I'm still very new to Ubuntu and I need help resolving an issue with my wireless. My connection shows up clearly as "dlink" but ubuntu simply won't connect to it. It worked fine downloading updates during the install. Could you please help?

Here is the output of lspci

Hm, I think this is an old bug, which affects some wireless adapters: When wired connection is enabled, wireless will disconnect after some seconds (or the way round, I don't remember exactly). To solve this you have to disable the connection you don't want to use. Greetings
