I have a strange problem since moving from Vodafone to TrustPower ADSL with my previous configuration working flawlessly.
My symptoms are that with my new TrustPower-supplied desktop wired to the ADSL router (Netcomm NB604N-NZ) I have no problems connecting to and surfing the web

If I plug in my Linksys EA6500 (running as a WAP in bridge mode dishing our addresses via DHCP in a separate subset to the DSL router) into one of the Netcomm LAN ports, after about two minutes the internet on my wired PC (and WiFi devices slows to a halt. See below for a trace route to www.google.com from my wired PC. You'll see it's flying along nicely @ ~22ms and it starts slowing at about the 130th ping iteration and then times out

Ping statistics for 131.203.2.42:
Packets: Sent = 140, Received = 139, Lost = 1 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 22ms, Maximum = 3759ms, Average = 142ms
I also have a Yealink W52P VOIP handset and similar behavior occurs plugged into the Netcomm with or without the Linksys.
I have not changed the config on the Linksys or the Yealink. The Netcomm is out of the box as per TrustPower's supply.
What is strange is I cant ping the 'external' interface of the WAP (the Netcomm side) but I can see the Netcomm DHCP server has successfully dished out an IP address.
I'm beginning to this I should give both the VOIP handset and the WAP static IP addresses. Other than that, any clues?
thanks in advance!
