I've had my Linksys BEFSX41 router for ages. Somewhere along the way, I added a separate Linksys WAP54G to our network.
Recently, came across an extra Linksys WRT160N that was not being used, and installed it to replace just the Wifi function of the WAP54G, but still kept the BEFSX41 as the main router for home.
OK - so, any comments on finally retiring the Linksys BEFSX41, and just let the Linksys WRT160N handle all the router and WiFi functions ?
