Actually, it gives every indication that it's up and running. The wifi symbol is almost full-strength; however, the system monitor app shows weak or no real net traffic incoming. This will go on and on with me enabling, disabling, rebooting, trying Web, ssh, ping. But eventually it will work. I've got other family members on Thinkpads (T61, T410) and U14.04 and they don't have this problem.

I wonder if there's some laptop-mode thing that's causing issues. Things that come to mind are wlan power-saving mode and rfkill. Speaking of which, what's rfkill say when you're struggling?Also, could you clarify "works" and "doesn't work"? Do you mean that you can't get even get it to scan for access points, or just that it won't connect (or something else)? If the former, what's "iwlist wlan2 scan" tell you (when it's otherwise not working)?Cttoi, I'm left wondering why your is adapter wlan2... This might suggest some sort of driver issue, I guess?

Some more specific details would help.
I believe putting 'lshw -C network' in a terminal (without quotes) should give you a list of the network bits in your laptop. Don't hold it against me if I'm wrong though, I don't have a linux box with me to try it out on.

> I'm new to this state (up in Elkhart) and I'm on U14.04 on my Thinkpad X201. I could not get Wifi to work at all initially. Then a Xfinity support person "changed something" and it . . . sort of worked. That means it worked after fiddling with enable, disable, (I'm on Gnome classic). Actually, I don't know what I would do, but eventually it would work. Then I'd put it in suspend, come back . . . and it wouldn't work. Repeat fiddling, rebooting, etc., then it would work. Any ideas what I'm having probs with?
