Tor overwhelms my router

[Alan Brause]

I finally had to shutdown my Tor server because my Linksys WCG200 NAT 
broadband router can't keep up with Tor and 3 other clients on my LAN.  
The router does not crash outright, but I lose DNS and pings become 
unresponsive.
I have throttled bandwidth to 150Kb/s and that didn't seem to help.  I 
thought about limiting the number of connects but I read recently in 
this forum it is not recommended.

Can anyone suggest a suitable NAT router for use in a LAN that can 
handle Tor traffic?

Thanks,

Alan
