Hi hmscott,

first of all thank you for your answer.
I ofc installed setpoint, and i haven't had any problem syncing my mouse, any.
But when i use it, sometimes it has horrible lags, or delay, 1 every 30 min +/-.
i didn't install the wireless driver of asus, i let the pc install themselves when the pc upgraded to 8.1...
The only problem i think could be, is that i have my router 3 meters from me, and it is dual band 2.4 and 5 ghz.

this is so frustrating because all i tried didn't work, and i keep having these lags, i had a logitech mouse wireless before,it was like my m557 but it was wireless with a dongle, it worked perfectly for 5 years....
But this doesn't want to work, and i dunno why 😕

eliuss89, try installing the hardware driver specific to your Bluetooth hardware, not using the Windows installed driver.

The Bluetooth connects directly with the laptop Bluetooth, the router doesn't get involved.

Did you check what hardware you have installed for Bluetooth before blowing away the Asus Windows Install? If you still have that HDD, boot on it and check what hardware you have installed, and update all the drivers as below.

They aren't Asus drivers, they are hardware drivers from each manufacturer that Asus hosts from their website.

Here is the list of places I look for updates for my G750JH; the best way to get a stable fully functioning G750/G751 is to update all the drivers / apps to the latest Windows 8.1 release.

The G750JW/JX/JH/JM/JS/JZ download areas haven't had new updates for a while, BIOS updates still happen in your model's support area, so check there from time to time.

The G750/G751/551/500/etc share the same basic hardware components; check support download areas for new hardware for newer drivers.

Asus maintains central support areas for hardware component features common to all products, those areas usually have the latest drivers after new hardware releases, sometimes there is a lag before the newer drivers show up there, so still to new product releases support downloads for the latest drivers.

Asus G751 Support / Download areas - Asus hasn't updated all the versions of these support areas, this link discusses the 3 locations were started independantly and not sync'd/updated through to the latest driver releases - check them all to be sure.

Here are the latest Asus posted VGA drivers currently 347.25 ; it's better to get the latest from Nvidia - 347.88

Asus doesn't modify the drivers, they release the identical driver packages as Nvidia releases.

If you are running only on Windows installed drivers you aren't getting the most from your laptop, and will likely continue to have problems like the BT lag 🙂

You can try installing the BT driver first to see if that is enough, but installing all the updated Windows 8.1 drivers is best.

Let us know how it works out 🙂

Maybe i didn't explain correctly what i meant.

I installed latest drivers i found on asus support for windows 8.1, followings:

http://www.asus.com/it/Notebooks_Ultrabooks/ASUS_ROG_G750JH/HelpDesk_Download/

And couldn't solve the problem....

eliuss89, that is because Asus doesn't update the download area for products after release, that is why the big long list, and the explanation that the JW/JX/ JH download areas aren't up to date. They have old Windows 8.1 drivers...

G750 support areas - The JM download area has the latest of all the G750, with JS/JZ next, the G750JW/JX/JH are out of date:
http://support.asus.com/Search.aspx?...750&ps=10&pn=1

The G750JH download area Windows 8.1 drivers haven't been updated, the G750JM/JS/JZ driver downloads are newer, and the general download areas are even newer. Get the idea? 🙂

When the G751 models are released, those download areas will be worth checking too.

Please look for newer Windows 8.1 drivers in the other locations, and compare the driver versions available, download them if newer, and update.

Let us know what you find, and how it works 🙂

Oh now i see, i'll check them and i'll let you know it, thanks really so much hmscott! 😄

eliuss89, np, it surprises everyone the first time, why Asus doesn't backfill all the download areas for products using the new drivers... but you get used to it, and learn how to forage through new Asus Product releases to find the latest drivers.

Have fun! 🙂

last bluetooth driver of the list isn't helping, mouse still get lags 😞

eliuss89, from what Version to what Version, of which driver? 🙂

Also, when you change drivers, delete the device from the Bluetooth driver list, and re-pair it.
