My son installed 11.04 on his Acer Aspire 5742z-4601 laptop for dual booting after using the live cd and everything worked perfectly. Now that it is installed, Ubuntu doesn't even attempt to find the wireless network. With the livecd, it was simple as picking it off a list and entering the password. I have made him an administrator, which entailed checking him off to access wireless networks, but no go. Does anyone have an idea what may be going on here?

Thank you.
