I've been using Linux Mint 9 Gnome for the past few months. I've thus far had no problems that I could not work out myself, until I installed KDE-full. I've been a Gnome user since coming to Mint from Ubuntu. I've been reading some good things about KDE 4.5 so decided to give it a try. First thing I noticed was I couldn't get online. I'm using a wireless usb adapter Rosewill RNX-N250UB. This piece of hardware works under Gnome fine, so I went on to explore my new KDE desktop. Checked out a few things, mostly system settings, and control panel stuff, trying to find networks and devices, configuring other little things along the way. I could not find any settings to connect to wireless networks. Secondly there's a usb device application of some sort that autostarts when you log in to KDE, tells me I have no usb devices connected, yet the wireless adapter sits plugged in, blue light blinking away. If someone could please help me connect to a network under the KDE desktop, and possibly explain why this is not a problem on the same system, under Gnome, this would be extremely helpful. Also under KDE system specs under USB, wireless adapter is present.

note that there has been much recent work done on the kde network manager (see http://lamarque-lvs.blogspot.com/) and it may not have been ported back to 4.5 so I would suggest up'ing to 4.6.2 which is current

as an interim solution you should be able to run the Gnome network manager under kde - this tutorial is for openSuse but should help http://susestarter.blogspot.com/2011/03 ... gnome.html

is the ralink driver package installed?

I don't think the devicebnotifier would show network cards just mountable devices
