Help! I’ve stuffed up my adsl router address

I’ve stuffed up my adsl router ip.

Setup : network 192.168.1.x netmask 255.255.255.0
on a linux network

Original – router ip 10.0.0.2 netmask 255.0.0.0

Firstly communicated with router by setting an ip alias on eth0 of 10.0.0.1 netmask 255.0.0.0 – and communicated fine, so I decided to change the ip to 192.168.1.10 netmask 255.255.255.127 (don’t ask me why 127, just thought I’d try it!), then rebooted the router.

Now I can’t see it or ping it. I’ve tried various ip aliases on eth0, and adding gateways to the routing table, but now I’m stuck.

Any ideas gratefully accepted.
