I am visiting my folks who have a westell7500 modem. I am running kubuntu 10.10 on a lenovo c200 with an internal network card and can connect to most wireless networks that I encounter. With this router/modem, network management finds it when doing a scan and I read that I enter the SN for the ssid and the WPA# for the password. I have gotten it to connect for a few minutes but then it asks for the password again. If I switch over to my windows partition, I can connect with no difficulty, so I don't think it is a hardware issue. I have tried both the internal network card as well as a netgear wg511 pci card with the same results. Any ideas how I can solve this?
