Hi,
Cisco router in Melbourne is disconnecting more frequently Apparently it disconnected 4 times today, If it is restarted then it works again for a while, but eventually it disconnects from the internet and doesn’t attempt to reconnect
Can anyone help me ? this router has been a problem never have managed to get it to be reliable
the question is whether there is a hardware problem or a config problem
im sure the internet stops and starts all the time but this router doesn't appear to reconnect
also if swap router to BILLION from Cisco then all is fine
interface Dialer0
mtu 1454
ip address negotiated
ip mtu 1452
ip nat outside
ip virtual-reassembly
encapsulation ppp
ip route-cache flow
ip tcp adjust-mss 1452
dialer pool 1
dialer-group 1
ppp authentication pap callin
ppp chap refuse
ppp pap sent-username XXXXXXXXXXXXXXXXXXX password XXXXXXXX
Warm Regards
Vikrant

Hello,
Thanks for your quick reply, I didn't get ant error or any log, i am not sure why,
if it's disconnects from the internet and doesn’t attempt to reconnect, it should be connect Automatically, but if i restarted manualy by using power switch then it works again. I am very much irritate from this issue it will be a great if you will help me, i did post this issue on many forums but same issue yet

hi,
i've observed bouncing more on the LAN FE ports. what devices are connected behind your 877? if WAN is still intermittent, i would suggest to try replacing the RJ-11 cable or try connecting directly to the phone wall socket without the the splitter or fax connected with it. lastly if all still fails, ask your ISP to have a technician to inspect for any wiring problem.

Hello,
Thanks for giving comment, we are mostly using wi- fi, only two system are connected to FE LAN ports by RJ-45, we have issue in All System (WI-FI also LAN), If restarted Cisco Router then it works again for a while, but eventually it disconnects from the internet and doesn’t attempt to reconnect
if I change router menas swap to Billion Router then all is fine,
Please look on Snap when i lossed internet
