    I recently noticed I can no longer get to www.usps.com or www.bankone.com. Pings just time out. After a lot of troubleshooting, I determined the router to be at fault. When I removed it from the picture and connected a PC directly to the cable modem, there was no problem. All users behind the router are affected the same.

    So, what can be causing this? Has anyone else encountered it? Is there any known solution?

    I have upgraded to the latest firmware and reset the router.

    A tracert of www.usps.com ends here:

     16    42 ms    44 ms    43 ms  POS6-0.GW3.CHI2.ALTER.NET []
     17  usps1-gw.customer.alter.net []  reports: Destination net unreachable.
    while a tracert of www.bankone.com ends here:

     17    61 ms    59 ms    68 ms  bankone-gw.customer.alter.net []
     18     *        *        *     Request timed out.
    (maxes out to 30 hops)

    So is this some sort of incompatibility with alter.net?
  2. I have experienced similar issues in the past. Take a look at your MTU settings on the router. I bumped mine down to 1492 (from 1500) and have not had any more issues.

    You can also try 1400 and 1300 on the MTU if 1492 does not work.

    Although 1492 worked for me before. :)
