Wohhoo... I found how to fix my router. It's only possible when you set the manual IP adress with ip, mask and gateway and switch-off/on with pressing the restart button and connect using telnet while ten second. So now I can go into the telnet console. Now I have another question: which version of openWRT is better to compile? Is it possible to find somewhere precompiled version of the image?
And another question: how to downgrade to the original firmware. What can I do?
In your manual you are loading vxworks.raw
RedBoot> load -r -b %{FREEMEMLO} vxworks.raw
where did you found this raw file? Loaded using the TFTP?
Thanks,
Dmitry
