Can not telnet Cisco 1601

[mocale]

Can not telnet Cisco 1601 when E0 is connected, only after I disconnect E0 from hub and reset router I can login.

the conf is as follows:
!
line con 0
transport input none
line vty 0 4
password 7 020F065211075678
login
!

Any sudgestions, is it possible HUB is damaged.

TIA

try this
router>EN
router#(config) line con 0
exec-timeout 30 0
password ????
login
transport input none

The only thing that was added was the 30 min timeout .
When you try to telnet and it does not work what appears on your screen ?
Can you ping the interface when this happens ?

When I try to telnet and it does not work I get...

% Destination unreachable; gateway or host down

But still i can ping the S0 and E0, and there is flow of traffic on both legs

TIA

You may want to verify that you don't have an access-list preventing telnet.

WOW , son of one has a good idea there on checking for an access list . However lets
look a little closer at the ip addresses on the LAN and make sure the gateways are
set up correctly . Heres an idea , remove the ethernet from the lan and hook it directly
to a lap-top, keep in mind your ip and gateway . Try to telnet in , if this does not work than it would appear to have some form of an access list set up . If possible can we see a sample of your config ? We have a 1601 here in the lab and it works just find !!!
Oh , also do a show arp to determine what the router is seeing on the LAN . Good Luck !!!

No access list on router, when i disconnect lan and reset i can telnet.
here is sample conf

Have you done a" show proccess cpu" on this RTR. I have seen a MSFC RTR in a Cisco 6500 get an SNMP engine ID on it's own after I turned on Informs. This caused my router to approach 99% usage because the SNMP process was using availabe bandwidth and walking all tables. It would not even let me Telnet in. I know you did not put that 100 number SNMP engine ID. Try doing a "no snmp-server engineID local XXXXXXXXXXXXXXX"

add this line

ip default-gateway 1.76.254.1
(or whatever)
