Hello,
I have a Dell XPS 420 with Ubuntu 10.10 (2.6.35-23-generic x86_64).
My internet used to work (out of the box) without any problems, but after install of Windows Vista (Home Ed. 32bit), I am unable to use the internet in Ubuntu. The network card is a Linksys WMP600N Wireless-N PCI Adapter. In Windows it works without problems.
In ubuntu, the network manager indicates that I am connected to the network, and I have an IP address in the 192.168.* range. I am able to ping the router, but unable to ping outside addresses. I have not changed anything, but still my wireless connections has stopped working. Does anyone know how to fix this?
