Surface Book and AT&T Unite Pro Wifi Issues

I have a new Surface Book i7/16GB/512GB laptop and I also own a AT&T Unite Pro ( Netgear ) wifi hotspot that I have used with my Surface Pro 2 for almost a year with no issues. With the new Surface Book you see the UnitePro in the available wifi devices and it connects just fine. Open a browser and it surfs the internet fine if you hurry because after about 10-20 seconds the wifi connection closes leaving you without internet. Go back to wifi list in Windows 10 and the UnitePro has disappeared. The only way I can get the UnitePro back in list is by restarting the hotspot. You can watch the Windows 10 available devices and it appears. Make your connection and 10-20 seconds later it is gone again. Strange thing is when hotspot disappears from Windows 10 list and connectivity is gone the UnitePro says the Surface Book is still connected.

Now all that being said, I can turn on internet sharing on my HTC Windows 8.1 phone and the Surface Book uses that wifi connection just fine without errors or loss of connectivity.

So does anyone have a clue on how to use the AT&T Unite Pro with the new Surface Book just as I have for almost a year with my Surface Pro 2?

Answer

try this and report back with results. if it does not work, change the parameter back.

1.Press Windows button. Search for regedit. Open it

2. Navigate to the following path:

 HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\mrvlpcie8897

3. Find the item labeled “TXAMSDU”. Double tap and modify the value from 1 to 0

4. Restart the machine

Cause:

Microsoft states there a known issue with the .41 Marvell driver that results in low throughput with specific access points. The issue is specific to MAC layer aggregation (AMSDU over AMPDU) and only impacts a small subset of access points. They state they are working on a fix for an upcoming update. Until the fix is available, please update the registry key setting to work around this issue
