This weekend I upgraded KDE4.2 to KDE4.3. For whatever reason, the upgrade didn't go perfectly well, so I removed KDE4.3 and then reinstalled it. The second time there were no errors during the installation, but I lot of applications/settings got lost. Let's deal with the networking issues first.
I thought that the networking issues may be related to Knetwork manager (lots of forum posts about it being problematic), so I installed Wicd. Installing Wicd made no difference - still have the same problems (see below). The two main networking problems are: (1) i can't get a wired network connection established. I am on the UC Davis campus in my office. I click the button to connect and it just hangs on "obtaining IP address". Under the Wicd preferences tab, I have the DHCP client, Wired Link Detection, and Route Table Flushing all set to "automatic". Other people in my lab running, windows, mac and other linux distros seem to have no wired connection troubles. (2) my ability to connect to wireless networks is also limited. I can connect to SOME unencrypted wireless networks, e.g., I can connect to moobilenet. However, my labmate has a open wireless network setup (with our lab printer on it) which I cannot connect to. No encryption, no MAC address filtering, just an open 802.11g access point. I generally cannot connect to encrypted networks. However, I did finally managed to get connected to my wireless DSL router at home. I am fairly novice Linux user, so I don't really know what information i should be giving you in order to diagnose the problem. But below is the output of eight terminal commands that I hope are relevant. Since the output is kind of long, here is a list of the commands that I issued and indicates the order of the output. Maybe this will help you jump to the important parts of the output. % (1) sudo lshw -C network % (2) sudo iwlist scan % (3) lspci -nn % (4) lsmod % (5) route -n % (6) uname -r % (7) sudo iwconfig %
