Wireless Network connected however 'Network Unreachable'

[alex_r]

I've configured a wpa wireless link to my router and it says I have connected - with a graphic at the top telling me the signal level/status etc.

However when I open firefox I can't see the internet. Pinging my router (192.168.1.254) produces 'network unreachable' and I don't know what to do. Here's some statements I ran - can anyone figure this out for me?

Please see below for all the commands other users get asked.

Many thanks in advance!

I had a similar problem, but I found that it was intermittent.
Rebooting fixed it.
Not sure if you using wpa and me using wep, would make any difference.

Why is your default gateway 192.168.1.254, change it to 192.168.1.1 subnetmask 255.255.255.0
