I've connected my Aironet 1200 to my cable modem, and configured it to receive its IP and DNS-server addresses per DHCP. Well, this works fine. It's being assigned the correct ip address and the correct dns servers. However, I can't ping anything on the net, not even the dns server. I noticed in the "sh ip traffic" output, that every ping results in a packet drop caused by "encapsulation failed". According to the output ip packets are coming in and going out all the time... So can anyone please tell me, why I can't ping any address? I didn't find any command in the Aironet IOS to change the encapsulation..
I'd be grateful for any help
