I did some more testing on different versions of Ubuntu. I installed on the same machine Ubuntu Precise and Maverick. On Ubuntu Precise 12.04 alpha 2 (with all current updates), I have the same behavior : channels>11 seem unreachable
But on Ubuntu Maverick 10.10, it works! It's certainly because Maverick does not use the same driver for Broadcam Wifi network adapters. By default, the wifi does not work, but Maverick suggests to install proprietary drivers : "Broadcam STA wireless drivers". After installing this suggested driver, I can connect to my wifi on channel 13, and the reported driver is "wl". If I restart on Oneiric or Precise, this same Wifi is not detected. That confirms it's not a hardware problem. It makes me suspect a bug in brcm80211 driver -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/931168 Title: brcm80211 Wifi driver : cannot connect to channels>11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/931168/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
