Odd problem: Belkin N1 access point, connected to our business switch, slows the net

[markm75]

In our business network, we have a sonicwall 2040 router connected to
our comcast static ip modem.. the sonicwall connects to a gigabit
switch.

We had been having some internet connectivity issues.. The internet
would drag, ping times in the 300 etc..

I was able to find the root of the cause and surprisingly, for
whatever (yet to be determined) reason, our access point seems to drag
the internet connection down when connected to our switch.

I am not really sure why this would be the case, perhaps its just a
faulty belkin access point (f5d8231-4), as i have 3 switches, I tried
plugging it into each, each time the same results (though it starts
out fine, then by 30 seconds the ping times are bad).. I can say that
noone was connected to the N device during any of these tests, I also
tried various combinations of settings like N mode only, n and g, etc,
none of which made a difference.

Anyone run into this before?

Thanks

I'm probably going to need more info, but from what it looks like, you
got two routers in your system, the Sonicwall 2040, and the Belkin N1.
It also sounds like the Sonicwall is your main firewall/router to the
Internet. Meanwhile you're just using the wireless features of the
Belkin, but you really don't need any of its routing/firewalling
features. As such, what you should do is disable all of the routing and
LAN DHCP features of the Belkin. Also you should connect the Belkin to
one of your switches via its ethernet LAN ports, *not* via its ethernet
WAN port.
