Hi people

I have been having ongoing issues recently. It appears to be related to DNS. I am on the fusion plan.

When I set up the ADSL connection, my router WAG54GP2 is allocated 2 DNS servers:
58.28.5.2





58.28.6.2





I telnet to the WAG54GP2, login as admin and then:
   Router(main)#ping 58.28.5.2
   PING 58.28.5.2 (58.28.5.2): 56 data bytes

   --- 58.28.5.2 ping statistics ---
   4 packets transmitted, 0 packets received, 100% packet loss
   Router(main)#ping 58.28.6.2
   PING 58.28.6.2 (58.28.6.2): 56 data bytes
   64 bytes from 58.28.6.2: icmp_seq=0 ttl=60 time=50.0 ms
   64 bytes from 58.28.6.2: icmp_seq=1 ttl=60 time=40.0 ms
   64 bytes from 58.28.6.2: icmp_seq=2 ttl=60 time=40.0 ms
   64 bytes from 58.28.6.2: icmp_seq=3 ttl=60 time=50.0 ms

   --- 58.28.6.2 ping statistics ---
   4 packets transmitted, 4 packets received, 0% packet loss
   round-trip min/avg/max = 40.0/45.0/50.0 ms

The primary DNS appears to be down. Despite this, the WAG picks up and uses the secondary DNS for between a few minutes and a few hours and then the local DNS proxy server on the WAG collapses in a heap and everything using the WAG DNS comes to a grinding halt. The only way to resolve this is to either reboot the router or to tear down the ADSL connection and re-establsh. This temporarily resolves this issue again, but this is not a suitable long term solution.

I have also got RTA1025W that exhibits similar behaviour when it replaces the WAG54GP2. Unfortunately, it does not have a telnet interface (that I am aware of) and I therefore cannot definitively test whether it has exactly the same issue.

Do I have 2x faulty routers or is there something else at play here?
TIA
