#48. You work as a network administrator at Braindumps.com.ua. A DSL subscriber says that his DSL modem is trained at the subscribed rates, 1024 kbps downstream and 256 kbps upstream, but he has no access to the internet. The internet service was working until today. The modem remains trained – it is not dropping train or frequently retraining. Manually retraining the modem does not correct the problem. The customer can ping from his PC to the Ethernet interface on the DSL modem, but not addresses “in the network”. Initial troubleshooting shows that the DSL modem can ping the subscriber’s PC, but no addresses in the network. What could cause this problem?
