Had ongoing issues with my new G550 but noticed that web browsing, youtube etc works fine on the wireless network but gaming (TF2, WoW) doesn't - ping is in the thousands and usually just get kicked off the server.
Has anyone else experienced this? Running Windows 8.1.

When I got my JZ, I used the wireless for everything like for 2 weeks tops and didn't had this issue, although now am on Wired for better connection, Wireless still works fine if i'm using the laptop on a different room or place, though I might not get the same result, but not less then it too. Pretty okay to play CS:GO, League, Dota and Tf2. I would suggest go to Asus Support page below and get the Latest Killer-N Wireless Driver along with Wireless Drivers needed for your laptop and then give it a shot, since you haven't wrote your Model, Click on 'Change My Model' in the top accordingly to the one you have then see what are the results as I mentioned, give it a shot and let us know :)

Thanks for the advice - I should have said I have been to the support page and tried all of the different drivers with no success.

slimo, which Wifi hardware / driver version does your G550 have?

There are other download areas than the G550 area, that might have a newer version. What router make/model and firmware version are you connecting to? How fast is your upload/download as advertised by your ISP?

Wifi config gets a bit complicated beyond driver/firmware versions, but making sure you have the latest for both is a good place to start. Then we can debug from there.

Try these other locations to find newer versions of your wifi hardware/driver in your G550:

@Slimo: I was having these problems with my non-Killer Broadcom AC card. When i installed the drivers from Asus the performance in games was catastrophal (like you said, 500-1000ms latency). But then i removed the driver from the device manager (along with the option to delete the actual driver from the computer) and just let Windows use the Microsoft default one. And believe it or not, THAT driver is the best. Works like a charm now.

theclaw37, it may work, but it possibly isn't the best / latest choice :)

What is the driver version installed by Windows Update?

Did you go to the Asus WLAN download area and get the latest Broadcom driver? Which Broadcom driver version did you try from Asus? Version V6.30.223.228 is the latest here:

theclaw37, the 6.30.223.102 is an old Broadcom driver distributed by Microsoft 5/31/2013, a newer driver should work better. It is possible you got a corrupted download of the 6.30.223.228 driver, I see a couple of instances of that download with different sizes.

I used the latest Asus downloaded Broadcom driver when I had my JX / Broadcom 802.11ac with Windows 8.1, and it worked fine with an Asus RT-AC66 connecting as 802.11ac, probably the 6.30.223.143 version or the one just before that.

Maybe try another 6.30.223.228 download point, or back off a version at a time till it starts working again as desired. The .102 is pretty old now.

What make/model of router are you using?

Check the router channel as well... if you got an android phone use WiFi Analyzer. Many people don't realize that the culprit of any gaming issue via WiFi could be as simple as an overwhelmed channel in the area. Cheers!

It's not the channel mate (the channel is pretty clear anyway). The link speed is very low, and as a consequence the bandwidth is low too. Anyways, if the problem was on the router side, i would be getting the same results with different drivers.

theclaw37, so far I have been recommending everyone that asks for a solution to a Wifi problem to update to the latest Windows 8.1 Wifi driver available for the Wifi hardware in their G750, some have been Broadcom, and none have come back and said that the current/newest driver caused problems for them, in fact it has always been the opposite - the problem is solved and they are happy - so I was surprised by your responses.

Settling for the Microsoft Update found driver is rarely a good recommendation. They are usually so out of date so as to predate the release date of the new hardware you are updating.

It just so happens that your router, if it is the V8 model, hasn't had a firmware update since the release date of the .102 Broadcom Microsoft driver release, both are from 5/2013 - so in your particular case - that might be the best Wifi driver as it is the same month/year vintage of 802.11 design spec.

http://www.tp-link.com/lk/support/download/?model=TL-WR841ND&version=V8#tbl_j

If the .228 driver you download wasn't corrupted, then something in the 802.11n firmware implementation in the TL-WR841ND doesn't respond well to the current 802.11ac Broadcom driver.

Maxter, very true, response tactics to congestion can vary between driver/firmware releases and produce unpredictable results - what worked fine in the previous release completely fails in the same scenario in a new release. I have seen that happen a number of times. Reporting back the bug, or fixing it myself - and/or rolling back the driver is the result :)

Just taking a look at the Wifi landscape can open your eyes to an unseen world - with surprising perspective changing results.

On Windows I use inSSIDer, on Android I use Wifi Analyzer (farproc) and recently a new Wifi Analyzer (WEBPROVIDER) - I don't like that they have the same name, but I like the new interface - it lists AP's on the same channel as your AP, and recommends a free channel to move to - a nice touch.

Here is how bad it can get, and you would never know unless you looked :)

Hey Scott. Yea, my router is pretty old and apparently has no updated firmware. I'm travelling next week and i'll have a whole new world of routers to test the laptop against. Maybe i'll update the driver beforehand and see how it performs.

The only channel-related problem i had is that the router can't keep a 40MHz connection with my laptop, and as a result, no 300Mbps link speed. The area i'm living in is probably very crowded. Anyway, i'm probably going to revert to good old ethernet until maybe i'll get myself one of those gigabit port/AC routers.

theclaw37, cool, I saw the TP-Link Archer C7 for AC17590 for only $99! But, the V2 model hasn't had a firmware update since the initial release back 11/2013 - maybe TP-Link just gets it right the first time?

http://www.tp-link.com/lk/products/details/?categoryid=2872&model=Archer+C7

That is an odd one, not being able to build a 40mhz link, even when forcing it, so that is a sign of incompatibility.

For me the only available option was to use a 5ghz link, and turn off the 2.4ghz link so I didn't add to the congestion, I got a clear space on 5ghz all to myself :)

Let us know how the update / router upgrade goes!

So for an update:
Took my laptop to the service centre, they replaced the wifi card. Still unable to game online, ping of 1800 - 20000ms.

Tried various drivers from the ASUS website (including letting windows choose), no improvement.

Any other advice? To reiterate streaming videos, downloads, etc are completely fine, just get horrendous latency when gaming.
PLEASE HELP!!

Slimo, you haven't said what router you have or if you have updated it's firmware... or what your ISP download/upload advertised speeds are, and what you are getting for download/upload speeds - or what ping time you get to standard test sites - get us some more data so we can help you.

And, there are lots of games that get horrendous latency when everything else is working fine. Try other gaming servers, games, go to the specific game support sites and look for help there.

You have pretty much confirmed your laptop is ok now, so work on the router update, ISP, and specific gaming sites for tuning help.

Come back with the details so we can help you.

slimo, now do the same thing to the gaming servers you are connecting to, do it a few times to each site - the gaming server itself - not the support site - to see if the ping times are low enough to support game play, and steady enough to not induce occasional latency.

When you play multiplayer and you select a gaming server, you do sort by ping times and connect to the lowest ping time server that has a player slot, right?

If you find the ping times are low, then it isn't the network inducing the latency, it is something else.

Do you use an HDD or an SSD as the install/play drive for games?

Slimo, cool, now we know your link can provide low pings: google.com/TF2 servers, but your WOW server is 145ms, so if it was me, I would contact the ISP, and ask them if they can improve their path to WOW... it is possible for them to tweak their BGP partnering to provide a better latency - it is a combination of a geographical / distance / multi-hop problem.

Where are you physically located? How far in km are you from the WOW server?

You pay a penalty of about 1ms per 100km distance (200km round trip time). So if your base latency is 15ms and each hop is 2-10ms, you can calculate the distance by the remaining ms - or if you know the distance you can work back the number of hops - I'll let you do the math ;)

So it looks like it isn't a problem with the laptop, wireless, DSL, but it might be something your ISP can help with - be very friendly with them, positive, and appreciative and you might get a positive improvement / result.

You might want to go through all your games and figure out if there are any more latency issues - so you don't keep going back to the ISP - get them all the problematic routes in one request.

Let us know how it works out :)

slimo, did you test the latency on both laptops at the same time? It might have worked in the past on the old laptop, and now with the new laptop the routes have changed - or maybe a WOW server was available closer back then. The routes / situation can change from minute to minute as well. If you still have that laptop test the ping latency on both laptops at the same time :)

Have played on both laptops - 5+ year old HP laptop plays fine, 150ish ping (good for NZ), flash new ASUS laptop 1000ms ping (minimum) has gotten up to 20000ms.
Both on wifi in exactly the same position (right next to the router).

VERY disappointed with this, getting pretty fed up trying to get this to work. Must be a Win 8.1 or ASUS issue.

slimo, no need to affix blame until we know what is causing the problem.

You said you were getting 150ms ping's to WOW from the G750 earlier, what changed? What do you mean by "flash new Asus laptop"? Did you do another reset on the OS for the G750 since getting the 150ms pings?

Please stop changing things and get the G750 patched up the the latest Windows 8.1 Microsoft updates + Windows 8.1 drivers, not just Wifi, and then we can debug where the problem is fix it.

At the same time as the ping test over Wifi, do a ping test on Ethernet so we can see the difference between ethernet and Wifi on both laptops.

Grab a snippet shot of the Wifi status - connection speed / etc, for both laptops - like this:

I have gone through forum after forum - all windows and driver updates are current, I have disabled firewalls and anti-virus and had the service center replace the wifi card, I have tried different wifi channels and used an interference/channel analyser...

Call me overly optimistic but it's 2014 and I was hoping to play a game over wireless internet with a gaming laptop.

slimo, a new gaming console, a new computer, any new network device they can both have incompatibility issues with other / older devices.

It isn't a big deal, and is common enough for you to want to gain the skills it takes to overcome this problem - you will run across it again - either at home or at work.

Did you run TCP Optimizer, setting the speed slider to the speed of your link? And, follow the other instructions to improve latency?

When you run on ethernet directly connected to the router with the G750, what kind of results do you get? You complain about the wireless link, but what do you see on ethernet?

The older Windows OS's had TCP tuned for slower links, but the Windows 8/8.1 assumes a faster internet connection, so it is tuned for larger packets and faster transactions - your slow DSL link is likely suffering for that tuning - re-tune your Windows 8.1 TCP with TCP Optimizer and performance should improve.

The reason I am not going to drop hundreds of dollars on a new router is that I took the laptop to a friend's house (who have an expensive new router) and I was experiencing frequent disconnects and couldn't download at 60Mb game update.

Slimo, can you swap the G750 for a new one at your seller? That would be the quickest replacement. Otherwise RMA to Asus. Replacing it yourself, opening the laptop and swapping the PCIE-Mini card might void your warranty, so it isn't recommended. You shouldn't need to go out of your way to fix the problem, let Asus fix it.

On Windows 8/8.1 I have had the Killer 1202 and 802.11ac adapter, and both ran fine with every router I tried, without disconnects.

If you want to do a complete reset / recovery restore to your G750 and try again, you can, but it looks like you have debugged this to a hardware issue, and if you have time left in your return period with the vendor, that would be the best / quickest fix.

slimo, you have a G550, so you want to look for the correct download version/series from your download area first.

It looks like the release you downloaded is from a different series - numbering is different - and this series is for your Wifi adapter - that is why you are getting the message you got.

The driver package you downloaded is either for different cards - or so old as to not have the right payload - you didn't include the 'dot' number version - but parsing it from the download name it is either very different or very old.

If that version has problems, then you will need to uninstall the driver you have installed first, do it from the Device Manager - uninstall the device and driver - if that option doesn't come up then uninstall the driver from the Programs and Features control panel.

slimo, those are both the same download areas, just with a different face/page layout.

The driver package you downloaded first: Version V1.0.37.1274 , is an older version of the newest Version V1.1.41.1277 at the top of the WIreless download section, but it looks like there is a different numbering/series Version V10.0.0.287, so if V1.1.41.1277 doesn't work then try V10.0.0.287

When you get the right driver update, don't forget to install and run as Administrator the TCP Optimizer to tune Windows for your connection speed.

slimo, I guess the only other thing I would try is to plug in a newish USB Wireless dongle into the G550, install the update software for the dongle, and see if the problem goes away. Just to make sure it isn't another Windows issue getting in the way of Wifi IP devices.

Otherwise, it sounds like time to get that G550 swapped back at the seller if it is still in the return period, or RMA to Asus with detailed information given in the Technical Inquiry / RMA request - and printed out and put in the box for the Engineer to find :)

802.11n speeds faster than 54mbps require using WPA-2 + AES Encryption, otherwise the connection is limited to 54mbps...

This specifications PDF from Qualcomm only mentions 2.4ghz.

You could use a USB dongle adapter to bring 5ghz and 802.11ac now, and power off the internal adapter.

Or, if your 2.4ghz landscape (congestion) allows you 100% speed (when you set WPA-2/AES on the router/laptop), a 2.4ghz 802.11n connection runs more than fast enough to provide 100% throughput for 99% of the internet connections you will come across, you could live with the AR9485 until a really cool Wifi adapter comes out later.

Also, there has been some discussion on the forum today about disabling WMM, don't do it, it may also limit the connection speed, the default setting should work - Auto or Enable. You shouldn't need to change it on the router/adapter properties.

This is the new router http://www.dlink.co.nz/products/?pid=1020

5Ghz security is WPA2 + AES
Updated drivers installed
Just can't find 5Ghz network
Also speedtest on this laptop only gets 7Mbps whereas old laptop gets 15Mbps. New laptop is connected at 150Mbps

Conclusion must be that the laptop is at fault. Have already had it fixed at ASUS service centre and the seller told me to take it back to them. All this adds up to a lot of running around and a large waste of my time.

slimo, your G750 Wifi adapter doesn't support 5ghz, just 2.4ghz. Details in my post above, look at the pdf file url.

Did you download and update the new router firmware? Or is it already running release AU_1.10_20140709 ?

http://files.dlink.com.au/Products/DSL-2544N/REV_T/Firmware/

40319

Here is the main page for your DSL-2544N router, it took me a little digging to find the firmware download... the Resources / Download link from this page fails:
http://www.dlink.co.nz/products/?pid=1020

So I went to the Support page, went to the ftp site, and searched in the big long list:
http://support.dlink.com.au/

Big long list:
http://files.dlink.com.au/Products/

And, dug down till I hit firmware :)

I would think if you have updated firmware and driver, you should be able to connect at 300-600mbps, not just 150mbps. What speed were you connecting at to the old router?

Read the Release notes before updating the Firmware:
http://files.dlink.com.au/Products/DSL-2544N/REV_T/Firmware/AU_1.10_20140709/Release_Notes.txt

The speedtest.net speed can vary, I test for a few hosts, the closer the better usually, but sometimes at various times of the day some sites slow down due to load / congestion.

I recommend initially setting up the router and getting the WAN/DSL connection set up on Ethernet, not on Wifi. Check your speedtest.net speed on Ethernet and get that sorted first before testing / tuning Wifi. After checking the firmware version installed.

Which driver did you end up installing on the G750, the one that finally worked / installed?

If you need 5Ghz, you can add one of these USB Wifi adapters

Slimo, I would try the other things first, to get your 2.4Ghz Wifi working as best it can, then you should be ok without 5Ghz. Your 2.4ghz will be more than adequate for DSL speeds.

If you want to replace your Wifi card, I would wait for a new Wifi card based on 802.11ac, at least a couple new ones should be showing up on the aftermarket in the next few months.

You need to pull apart your G750 to replace the Wifi card, it's not pretty, so I would find a local service shop - preferably an Asus approved shop - to do the replacement.

Asus itself won't do Custom work like upgrading the Wifi card, you get what was originally configured at shipment - that is why it is a good idea to google all the parts listed on the box / spec before purchase.

I don't understand why Asus would configure any G750 with a single band card - my original JW also had a 2.4ghz only Wifi - but it was the only G750 in stock at the time. I bought it at an Intel Haswell release event.

If having a single band 2.4ghz Wifi card really bothers you, I would suggest returning to the vendor for a JS with a dual band card, or a JZ.

slimo, you are throwing away a perfectly good laptop... only the Wifi is giving you problems, and it is fixable several ways. That Wifi part isn't even made by Asus.

Lots of other laptops / Wifi cards would likely give you similar problems to update drivers - router firmware - tuning, try to work with this laptop rather than giving up, you've already made a lot of progress.

Your recent complaint was about 1/2 throughput on the new router compared to the performance with the old router and the G750 - did you try Ethernet to see if the throughput was the same, or better?

Wifi/router/dsl debugging sucks, but you will need to do this with any new laptop / router / wifi connection for the first time through.

If you do pick another G750 with a 2.4ghz/5ghz Wifi card let us know :)

Internet is slower but stable. What i noticed it worked fine without repeater when laptop was placed near router. However from my room connectivity is terrible - big ping, random disconnects. On the other hand my 6 year old laptop works fine from my room without any problems at max speed.

Grothmog, with the G750 most problems are solved with driver updates and updated router firmware, but the G550 seems sensitive in compatibility with some routers chipsets.

It may be that your new repeater isn't just needed for improved signal strength, it may be that the Wifi chipset in the repeater is more compatible with the G550 Wifi chipset, which fixes the connectivity problem with the router.

What is the make/model/firmware release of the Wifi Repeater?

If that repeater solves the problem with the router connections, maybe Slimo can use it too?

Grothmog, that's weird, my JW/JX/JH all got slightly faster throughput on Wifi as on Ethernet - actually the same - but sometimes the load on the testing end favored the timing of the Wifi test :)

Even a 54mbps link should give your DSL speed throughput 100% on Wifi. You could try forcing Wide mode 40mhz to see if that helps, but a flat halving of performance doesn't make sense.

What is your Wifi Connection rate?

40798

Can you plug in the Repeater into an ethernet port on the router / DSL modem ethernet port, and serve ethernet speed through just the repeater wirelessly? That would remove the router Wifi from the path. And, see if the speed improves.

PROBLEM SOLVED works EXCELLENT WITHOUT repeater. I did 2 things at the same time so not sure which one had impact (probably second)
1st) Moved router in front of the doors (well now on back wall a bit more away then before but i believe it gave me better signal ^^)
2nd) there seems to be problem with intel drivers, they seemed to install ok but the driver date wouldn't change for me in device manager no matter what i did so I Uninstalled prevoriusly installed intel driver, then in device manager i chose my Wifi intel 7260N card and clicked uninstall driver there too. This removed my wifi card from device manager and uninstalled windows driver. Then I installed latest Intel drivers avalible for this card. Everything works perfectly and in device manager i have proper driver date, version, i have stable max internet speed.
I have yet to confirm ping in games.
@Edit Lol completly playable ping around 60-70 had only few lag spikes for 1 sec in nearly 1h game
Could anyone having problems check if this works for them too?

Grothmog, that's great!

I think you are the first I have seen with an Intel Wifi from Asus, most have been Qualcomm/Broadcom, so that trick of uninstalling the Intel driver from the Programs and Features and then uninstalling the device/driver from Device Manager is new too.

Suggesting you try the repeater alone was to see if it was a chipset incompatibility in the router vs repeater and the laptop - just trying to vary the endpoint to see if that made a difference to try to isolate the cause.

Sitting next to the router to test as well as far away is a good idea, sometimes getting close can over drive the receiver on the router/laptop if your power is up too high. I usually run with the lowest power setting on the router / laptop card as possible, to reduce the range that both can be heard.

Did you install Intel WiFi Wireless LAN Driver Version V17.0.1.5 from the Asus G550JK download area, or did you find a newer version somewhere else? Where?

Glad to hear it is working! :)

1st I tried drivers from asus download area for g550jk, and when saw its working(like 15min without lags and disconnets on my max speed) did whole uninstalling process again (intel drivers -> windows drivers) and installed newest avalible drivers from Intel website for this card (found by auto update) 17.1.0.0.

I believe on both You should be fine I just tend to always install latest drivers if they are working properly.

Well i must admit it was good idea.

Grothmog, it's good to hear that updating to either the Asus newest Intel Wireless driver, or the latest from Intel worked. I use the same Intel Auto-Update to find things too. As it turns out it sometimes is a bit behind times too, like for the Chipset.inf I found a newer one by using the Intel search available through the download area, so now I try them all when looking for a specific update.

Do you have Optimus and therefore an Intel GPU driver as well? Did Intel Auto-Update find a new one? Trying the manual search might get a newer one as well.

When you got the same result from the repeater and the router, that does indicate either a new driver update was needed or the laptop Wifi was needing replacing, glad it was the driver :)

Now you can get your $ back for the Repeater :)
