Are you able to connect online using a LAN cable to the router ? I ran into this same issue after an updated download. Later I found that a lot of other Ubuntu users were running into the wireless (or lack of) problem also. I am using an Intel with a Linksys router. I had to 'Hardwire' my connection to get on line. After getting online with a Linksys rep, I had to enter 192.168.1.1 into my browser address line & reset my parameters. Hope this helps.
