I have a Wrt54g v1.0 using Openwrt Binary from Yani:

openwrt-g-code.bin      26-Sep-2004 17:33   1.5M 

After Flash was all ok,

Then Telnet and nvram commit ipaddr change and now DIag is red and no reset or tftp works?
I'm not the only one who destroyed his v1.0 with the current Openwrt!
It sounds like a Problem in the Openwrt Code.

Can any DEVELOPER solve this problem???
