dlink 624 XtremeG Router performance issues?

Hi,

I am having what appears to be router related performance issues.

I currently have a DI-624 Rev C2 and a DWL-G650 rev B4 (both 108
Mbps).
I have one hardwired computer and one wireless laptop.
I have the performance settings set to the defaults.
On my wired connection, I am running edonkey2k (p2p program).

My symptoms are that after edonkey has been running awhile performance
goes to hell on both the wired machine and the wireless laptop.
Shutting down edonkey fixes the issue. Unfortunately there are no
tools to view things such as dropped packets/bad packets etc on the
dI-624.

The funny thing is, I had an older DI-624 and a rev A DWL-G650 running
for about a year with the SAME machines and the SAME setup with no
such performance problems.

Is anyone seeing this? Does anyone believe it is related to their
ExtremeG stuff?
Does anyone know of a hidden URL for any debugging tools on the
router?
Does anyone know if their is an SNMP engine on the router? and if so
what the snmpget string is?

Thanks,
Ed
