routers and RFI

Can anyone out there recommend a router that doesn't generate much Radio
Frequency Interference?

I'm a shortwave listener, and I've found that my current setup makes too
much RFI. By process of elimination I have narrowed it down to my Linksys
WRT54Gv3 router. It isn't the b/g wifi, that's turned off and the WLAN
led is out. I don't need wifi, and if I did, I'd configure this old
router as a simple AP. The router has an injection-molded case,
apparently not much shielding.

Goal: I want to use fldigi for receiving digital modes like CW, RTTY,
PSK31, and all the others found these days especially on the ham bands.
Thanks for your recommendation.

Why are you using a wireless capable router? First step would be shell out $25 bucks at Newegg/Tiger/Walmart/Bestbuy and get a simple basic router w/o wifi. Or trade a friend one. There is going to be some RFI escaping regardless of how you have it turned off. Just go with the other
