Sonicwall kills Uverse DSL performance (even on other ports)

I have a Uverse DSL model that connects to a Sonicwall and then a switch that connects the rest of the network.  When a machine is plugged directly into the DSL modem, the ping times are in the 40-70ms range & the bandwidth is 11ish.  Once my Sonicwall(and the rest of the network) is connected to the DSL modem, the ping times drop to 500-700ms-even on directly connected LAN ports on the DSL modem and the bandwidth drops to 1-3mb.  The modem & Sonicwall are both set to auto negotiate.

Any ideas?

I think you are on the right track. Check the interfaces to see if there are any errors. Also try setting them up at 100Mb/Full Duplex.

Also, just make sure you only have one computer at the otherwise of the Sonicwall. Something could be eating your bandwidth so you want to rule that out.

I was thinking along those lines & have been sniffing the network with Wireshark, and nothing is doing anything.  Every machine in the place is on, but no traffic at all.  I'm back to thinking it has something to do with the sonicwall itself.

Turned out to be a little rootkit infestation that none of the junk virus scanners on the market picked up-but Combofix sure did.
