I have a Linksys Wireless-G Broadband Router  (WRT54GS) in my shack and have no 
problems with any of the 
amateur bands...

But it does interfere with the X10 wireless cams. (2.4 gig)

But, once I installed the router, I lost the working EchoLink (now can not 
receive).  I have tried to disable all the 
firewalls in the computer ZoneAlarm) (and the router) and have verified that 
the proper ports were set in the router 
and firewall with no luck.

Good luck and 73
