router - Cisco WRVS440N Keeps restarting randomly

    I have a Cisco WRVS440N Router, it keeps restarting at random intervals usually we can get by for most of the day before it happens. The logs were not enabled so I have no data to work with until it happens again.

    I had restored it to the factory settings and did a very basic setup to eliminate an improper setting but this did not solve the issue. Does anyone have any ideas what could cause it to restart like this?

    I did notice that when I ran the cable diagnostic utility that on "Port 1" that we have a Canon MFC8300 connected to it said pair A and B were ok, pair C had a short and pair D was open. After switching to another cable (undetermined good cable) it came back as pair A and B were ok but now pair C and D had a short. I will make a new cable tomorrow morning to see if I can get the shorts to disappear, but I am wondering if this could be causing the issue of it restarting?

    Without logs, any suggestions as to the source of your router's trouble would be pure speculation: not particularly helpful and rather unproductive. On advising a next action, you're already well along.. Enable the logs... Perhaps there may be some clues in them as to the trouble source before the next crash...

    Ensure your software is up-to-date.

    If you've a Cisco support contract, you might wish to open a case with the TAC, as they can alert you to any known issues with your particular product. (I can't tell if this is an enterprise or SOHO device based on its feature-set, so this may not apply.)

    For the wiring errors, ensure you're using the proper pin-outs, as a specific twist order are key to prevent cross-talk. Use of this standard is highly recommended.

    I've configured ADSL and added new public LAN IPs for the router. How can I reconnect DSL connection and apply the new configuration without executing the command reload?

    These are the commands I am using for DSL configuration:

     config terminal
 interface dialer 0
 ppp chap hostname User
 ppp chap password 0 Pass
 exit
 exit
 wr mem

    and these are the commands I am using for adding IP addresses:

    configure t
interface vlan 1
ip address xx.xx.xx.xx 255.255.255.252 Secondary
exit
wr mem

    Thanks!

    Just try shut / no shut on dialer port.

    conf t
 interface dialer 0
  shut #may be wait few seconds after this
  no shut
end

    And since this is not programming related, so, I am voting to close this (probably to superuser)
