I have put my computer to sleep twice and the wifi was still working. Okay I went to my wifi adapter and unchecked Allow the computer to turn off this device to save power I seen that option many times before since I kept going to device manager and trying to replace driver. I'm not going to make this change unless I see this problem happening, but I figured I'd mention it as it seems to have been common on win7 and win8 so we might run into that too. On a related note, a lot of people running win7 and win8 report that they get random WiFi disconnects where it drops and comes right back and they report that going to the advanced tab and disabling '802.11 mode' fixes this. I'm currently on the Intel driver, but I suspect this fix will work on the Microsoft driver too. I just slept 5 times in a row and it came back every time. I've bookmaked this topic and will check back if I find a solution, but for now I think I'm stuck.Īha! I got it! Properties of the WiFi adapter -> Power Management -> disable 'allow the computer to turn off this device to save power'. So, it seems that the problem is specifically WiFi authentication that is breaking, not the entire card.ĭisabling and re-enabling the device (either from device manager or network connections) restores connectivity until the next sleep. Trying to connect again shows me all the WiFi networks (so the card works enough to scan) but still can't connect.

Both drivers can't resume from sleep and the status gets stuck on 'attempting to authenticate'. Yes, that driver number doesn't match what Intel's web site says of '15.3.1' but that is what it provides.Īnyway, no luck so far. If I download the latest '15.3.1' driver file from Intel, I end up with this: Once I return from sleep, WiFi is broken.

WiFi works fine as long as I don't sleep. I have a Lenovo X61 with Intel 4965AGN wireless adapter and just installed Windows 10 last night.
