X220 always-on wifi

Hey guys,

So I remember how Lenovo included a "feature" for keeping the wifi on even when the system was in standby (for up to 90 minutes) so that when you came out of standby, it could associate with the AP faster.

I've been having SEVERE wireless issues lately, regarding reconnecting to access points on resume from standby, etc. (Takes 5+ minutes of fiddling with wifi and toggling on and off for it to finally connect). I believe that "feature" is the culprit... except I can't seem to find that setting anywhere. Does anybody know where to turn this off?

 

It is under Power Manager (right click the gauge at the bottom). Though, I turned it on once, and never found a way to turn it off.

 

Power Manager, Global Settings, Lid Closed/Instant Resume. Or right-click Instant Resume.

 

Thanks. Found the setting.. it seemed to be turned off, but I toggled it just to be sure. I've been having MAJOR issues with wifi on system resume.. if this keeps up I think I'll just do a clean install and try to have as little Lenovo crapware as possible (I consider their drivers crapware.. seeing how much trouble they've given me).

 

This may not be of any help - I have two Dell laptops with the same wireless chipset in, and they do exactly the same - very hard to connect to the wireless network after resuming from hibernation, but only with the wireless router at work. They are fine on my home router.

It may be worth trying on another router.

 

I've had problems with my home router and the wifi system at my university, however the problems are WAY more severe on campus than at home. At home I can muck with it for about 2 minutes and it will work. Earlier today, I spent about an hour on and off trying to get the wifi to connect and it just wouldn't do it. It connected just fine to the non-secure access point, but when connecting to the WPA2, no matter what I did it wouldn't give me an IP address, so the adapter just got stuck with a 169.254.x.x address which is useless. This didn't happen the first 2 or so months that I've had this laptop.. only recently.. and I've never had any other problems with any of my other wifi devices using the campus access points...

 

I know this may sounds odd but after having similar issues I disabled the bluetooth and voila. Now it works without any problem.

Also, you may want to fiddle a bit with the channel.
