Excuse me for bad english and may be for some mistakes in mind about mipsel - I am a stupid user, I can't port and compile any package by my-self. But I have a problem - udhcpc become useless with my provider. It worked some time, but one day it have changed. Provider's admin change settings of his dhcp-server and it's become not working. But my dhclient in Debian on the desktop is still working good and in google I find advices to make port of dhclient for mipsel to replace udhcpc and it will be work good.
Can anybody make that porting for whiterussian and give me the link for download or send me to mail: searcher(dog)ukr.net. Please, help!

Admin offer to use DD-WRT...

DD-WRT use udhcpc too and don't work
