View Full Version : g75vx ar 9485 wireless card disconnecting

04-07-2014, 02:15 AM
Hi, everyone

I am new here. I got a g75vx with ar 9485 wireless card. But it doesn't work well. It often disconnects while I play games or something. I don't know this is a driver problem or the hardware problem. So anyone have any solution about it?

Or if not, did anyone update the wireless card for g75vx? Any suggestion is welcome.

Try uninstalling it and re installing it.

Hey, I did this just last night by following these two videos:

I had the exact same Atheros 9485BG card, but it was giving me high Ms in games, even though I had the latest drivers from 2013-11-20, make sure you have them as well until your upgrade arrives. I upgraded to a Atheros 938X because I didn't need the Bluetooth offered in 9485BG. Other users who also did the upgrade chose the Intel Centrino Advanced-N 6250.

Basically, what you're looking for is a PCIe card of the size "half mini" with dual antenna. However, if your computer is under warranty or you're not qualified to make the operation (a lot of delicate ribbon cables to detach) you should consider buying a USB WiFi-dongle.

Thank you. I actually have done it. But it does not work.

Thank you. It is really useful. My laptop situation is that it would disconnect when I am doing download. I also tried to update the driver. But it cannot work.

Now I really want to upgrade the wireless card. Could u please send a link of the intel card? I mean the detailed model information. Because I found some similar cards on Amazon.

I can not personally verify that the 6250 will work in the G75VW since I haven't tried it myself.
Here's the spec in case you were interested in reading about Intel 6250: http://download.intel.com/support/wireless/wmax/6250/sb/intel_centrino_advancedn_wimax_6250_product_brief1 .pdf

What you should know is that I bought the Atheros AR9832 which gave me the Dual-band capabilities, so my connection went from a lagging 65Mbit/s up to 300Mbit/s. When gaming online the Millisecond response time went down from ~38 down to 22 and has been very stable ever since.
So I will definitely recommend the AR9832: http://www.ebay.com/itm/ATHEROS-AR9382-AR5BHB116-Wireless-Wifi-N-Half-PCIE-Card-/200821627890?pt=US_Internal_Network_Cards&hash=item2ec1e6dbf2

Thank you so much. I will have a look at them. Maybe the AR9832 is the best choice for me.

Thank you again.

well it might be the Intel 6230/6235's often is talking about. (6230 has Bluetooth 3.0 while 6235 has bluetooth 4.0)
while the 6250 is a WiMax capable thing with no bluetooth. no clue of what it is. but suspect that it is a Mobile broadband kinda thing for the USA
(my telecom, had no clue of what it was. here in Denmark)

and others use the Killer Wireless N - 1202.

I personally recommend the new Intel 7260 AC cards. it is dualband and is capable of the new 802.11ac the new speedy wifi stuff :)

with two antennaes wifi theoretical max speed:
Wireless N 300
Wireless AC 867

the signal is great. always have 100/100 Mbps internet with this on my schools net. the schools wireless N being the Bottleneck on the 5Ghz band :P

the other dudes that has those wretched so called Wireless N (AR9485 cards) runs on Wireless G with it's theoretical max speed being 54mbps

and they only get max 3/3 mbps and they are slow as balls, trouble connecting to the internet. and so on... even Acer laptops come with dualband wifi's and yet asus is still skimping on the wifi cards...

but the Atheros AR9832 sounds fine also since it is dualband and all. still recommending the Intel 7260 AC card.

Thanks man, I had forgotten about that brilliant brilliant card.
If we sum up some pro's and con's it would look something like this:

Atheros AR9832 802.11agn:
+ Supports dual band
+ Able to switch between 2,4GHz and 5,0GHz with just 1 millisecond latency thanks to FCS.
+/- No integrated bluetooth module.
- No support for 802.11Ac, which makes it slower when streaming big files through a WiFi.

Atheros Qualcomm Killer Wireless-N 1202:
+ Specially made for online gaming with the lowest latency on the market.
+ Includes bluetooth 4.0.
- No support for 802.11Ac, which makes it slower when streaming big files through a WiFi.
- The most expensive of the three.

Intel Wireless AC 7260:
+ 802.11AC, fast transfer when streaming large files.
+ Bluetooth 4.0
+ Backwards compatible with 802.11AGN-routers
- Some users have reported driver-related problems in Win8.

Here's a good review including the Killer N Wireless:
After reading it I pretty much want to upgrade again, gah :p

I think the driver related problems
Was when it was first released, on the market and there were simply no drivers for Windows 7

Maybe for windows 8 too... Never experienced driver problems though... Only on the 6235 card I had Bluetooth driver problems

The 7260 AC works fine with the most recent drivers. They probably have flatten out whatever problems there might have been in the start :)
Used it on: Windows 8/8.1/ and now 8.1 update 1 (got the leaked update files few weeks ago)

The new 16.0 drivers and up works fabulously. currently 17.0
Works well with my linksys AC router and other routers :)

Yeah pretty sad that a lot of screws has to be removed. To get access to the card :'(
