My wifi adapter keeps randomly disconnecting maybe once or twice a day regardless it happens so little, it's still very frustrating and I don't know what's causing it if it does it while i'm gaming i'm practically screwed. I am using windows 10 .
you posted this in the windows 8 forum when your on 10? (no worries, happens to the best of us)
is this a USB adapter? is it in a place where it could be "bumped"?
Used to happen to my mouse and fixed it. Imagine being in-game and you mouse stops working all of a sudden.
Go to device manager and locate "Universal Serial Bus Controllers"
Expand it and do the following for each one of them.
Right click and click Properties. Go to Power Management tab and uncheck all boxes.
If you see you device under Network Adapter in the device manager do the same.
If the problem persists search "edit power plan" in start. Click on change advanced power settings. Expand USB Settings and make sure "USB selective suspend setting" is disabled and "Wireless Adapter Setting" set to "Maximize Performance".
Hope that helped. Your computer basically turns the adapter off to save power. Please note your power consumption will increase though nothing noticeable.
i'd recommend using the USB2 port, as my adapter overheats somehow in the usb3 port, but works fine in 2. the software may actually not have power settings, it seems to vary by model. if you can't find it, it might not be an option.
