i can only telnet : as i set dhcp ip in router 871 :
here it ask for enable password ? which i didnt configure .......

sais

From what I understand, you have problems trying to obtain access to your router, despite the password recovery which you might have performed.

I'd advise you to follow step-by-step our password recovery article in order to successfully recover your configuration and reset your password(s):

Good luck!

i tired password recovery step
1 confreg 0x2142
2 reset
3 boot (its boot ios )

4 step its asking again username password . its not going usermode or privilege mode .

as i set dhcp ip address . i can telnet router . but can go to privilge mode . as it ask enable password which i didnt set .
but whn i enter sh version command .

my register show 0*0 ?
