RT2561/RT61 on ubuntu 9.04
My wireless Internet connection suddenly stopped working after upgrading Ubuntu Linux to 9.04 (Jaunty Jackalope). The LSPCI command told me my interface was using a RaLink RT2561/RT61 802.11g chip. The problem was solved after installing the WICD network manager from the repository. Apparently the Gnome network manager package does not recognize the RaLink RT2561/RT61 802.11g chipset. Oh, and installing WICD removes the Gnome network manager package. But that is okay.

@Dmitry: was this an upgrade from an earlier Ubuntu distro or a fresh install? I have read somewhere that the problem only occurs after an upgrade (and probably not always...)

So, my Gnome NetworkManager does recognize the RaLink RT2561/RT61 802.11g chipset and work perfectly. Ubuntu 9.04.
