I'm fairly new to Ubuntu, and this is the first time I've reached out and asked for help. Please let me know if you need any more information.
I did a clean install of Ubuntu 12.04 (64-bit) replacing Ubuntu 10.10 (32-bit) on my Samsung n150plus netbook last week.
Just before I did the install, we had a new router fitted with a new network and password etc.
My netbook worked fine with this router when it was using 10.10. But immediately after I installed 12.04, the SSID for that network was no longer detected. It does not come up in the list of available wireless networks.
However, if I use a wireless USB adapter/stick, it connects fine. The netbook's internal wifi also works when used with other wireless networks. But not with this one router.
Please let me know if I can give any more information that would help to solve the problem.
Some other details copied from comments
- The router is a Virgin Media Super Hub (VMSH) made by Netgear.
- My Samsung N150plus connects with no problem to other wifi networks. I appear to only have problems with this router.
- I tried using a friend's Mac and it had no problem establishing a wifi connection to this router.
