I have a laptop that dual boots to either Ubuntu 12.04 or Windows 7, but the I can't seem to do anything requiring an Internet connection on the Ubuntu side. I've been through the troubleshooting guide of clearing cache, restarting, etc. to no avail. The wireless icon on the top menu shows that I am connected to my wifi network but firefox doesn't work and I can't use ssh or sftp protocols either. The error message i get with Firefox is "Server not found." Any ideas are appreciated!
