I'm getting intermittent problems with internet access on my Ubuntu 12.04 LTS desktop when connected to my Prolink Wifi router. I have Android devices connected to the same router that are working fine so I know the router isn't the problem.

While connected, I'm able to ping my own IP address as well as, but I'm unable to ping other devices in the same network, nor are other devices able to ping me. I'm also unable to ping

Any idea how I can fix this problem?

It is safe to run it was written by me and some good friends it will help diagnose your wireless issue. Paste this command in a terminal wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script It will download a script and create a file named (wireless-info.txt, or wireless-info.txt.tar.gz) in your home folder paste the contents of the file here pastebin.com then paste the link back here. No internet then go to this link for running the script without internet. <ubuntuforums.org/showpost.php?p=12350385>; –  Wild Man Feb 28 '14 at 5:13
Paste the output of ifconfig and route -n commands. –  Jay Feb 28 '14 at 5:36
Strangely, I have another Linksys WiFi AP that is plugged into the Prolink AP, and when I connect to the Linksys AP, I'm able to get internet access. –  user1118764 Feb 28 '14 at 9:11
