I have a Qualcomm Atheros AR945WB-EG Wireless adapter in my notebook, it was fine in Windows 8.1, It would transfer about 6mb/ps and the general network speed wouldn't slow down when doing so such as browsing and remote desktop. However... with Windows 10 the thing is terrible, If I copy a file through the Wifi adapter to another computer on the network I am getting about 1.5mb/ps and while it's copying the wifi access is slowed to a crawl, I can't even refresh a webpage, and the remote desktop session doesn't move at all until the copy is finished. I tried removing the drivers and letting Windows update install the driver, it brought down version 10.0.0.321 which was newer than what I had. It made no difference at all, I hunted the internet and the latest driver I could find was 10.0.0.115 so I tried that also, no difference, same result. Has anyone else got this network adapter and if so can they try replicate my results It does work fine with small tasks such as web browsing and downloading files off internet and remote desktop is fine, its just when you copy files through the network (maxing out the card) that you notice the problems.
