today I updated my ubuntu 11.10 via the update manager. Now, the wifi connection is not working. I see my wifi station and the network manager also connects to the station but I cannot ping any other machine as well as connect to any other machine.
I use dhcp and I have disabled ipv6. If I call ifconfig everything looks fine, I see If my address. I also tried to setup the network manually without success. route also looks ok.
Any ideas what could have happend?
