My problem: I can see and connect to the network, most of the time (sometimes connecting does not work). My main problem is, that even when connection is established, I have no access to the internet. Resetting the router seems to correct the problem for a limited time (until it stops working seemingly arbitrarily). Other devices using the same router have no problem (1 Windows pc, 2 androids). On top of that, when I boot Windows on this very machine, there are no problems either.
I have run the analysis script from: My wireless/WiFi connection does not work. What information is needed to diagnose the issue?
My results are: http://pastebin.ubuntu.com/9215532/
Please help me!
