WiFi dies after returning from sleep/hybernation

So this has been a problem ever since I installed Windows 8 Pro on my Dell XPS15 L502X. Everything works fine but when I put the computer to sleep, if I come back after a lengthy period of time the computer will turn off, and when I turn it on it boots instantaneously but will not connect to the wifi networks. The Wifi icon has the little star to indicate that it is on and not connected and when you mouse over it, it says there are available networks however clicking it does not bring up the network selection panel. Mousing over to the right and clicking on settings does the same thing, wont bring up the network selection panel. Going in via control panel, the same thing. Logging out and logging in does not solve it either. It requires a full reboot. After a reboot it works fine again. This is not a problem with sleep if it is just for a short period of time, but for a longer (sorry I can't give you an exact time) it happens, and it is very annoying. Also it will not auto-connect to networks it recognizes in this mode.

Sorry for the bump, but I have something to add and no one replied yet. I found another thing,when you disable wifi using a hot key it wont change the sign on the bottom right. Basically disabling and enabling wifi does nothing.

Try turning fast startup off: Fast Startup - Turn On or Off in Windows 8. Not sure this is your answer, but give it a try.

Thanks znod, I just disabled it. I will reply here if it works or does not work. BTW, I was thinking about it and I believe this only happens if the computer is disconnected from the active network while sleeping (via being taken too far away) and then tries to connect to any network again. That would account for the extended periods of time, because the only time my laptop is put to sleep for extended periods of time is when i leave the house.

You are very welcome. The computer should disconnect from the network regardless of distance from the network when sleeping. Do you have an external Wifi connection light? If yes, then check it out. And, yes, do post back.

There is one, but the windows 8 drivers don't work with it, it never lights up aside from the LED "swoop" the computer does on boot. Speaking of which I picked the worst time to finally post (this has happened for a while), since we just left for spring vacation, and I live in my computer >.<

I'll find an excuse to leave soon, to see if I can recreate this.

So I left for a while and it did it again, even without fast boot.

Well heck. No more thoughts for now. I hope spring break at least was good.

Thanks for trying, and yeah the break is great

You are very welcome.
