Trendnet's TEW-637AP 300Mbps Wireless Easy-N-Upgrader

I have purchased for around $25 a new router add on to upgrade my existing WRT54GL Linksys router (G) to "N". Setup was pretty much straight forward, however I had changed back the TEW-637AP back to the A-G-N setting as I kept dropping out the Linksys signal. I had the new add on set to N so I could use the Vaio which has N for increased signal and thru put. May tinker with the settings later on in the testing phase for signal strength around the property. Using Vistumbler on the Vaio I want to see if the Trendnet add on lives up to its hype. For now all of the "B", and one "G" laptops are using the TEW-637AP. I will update as time allows. Some of the problems with the dropping out for Internet access may have more to do with Windstreams occasional signal loss from the land line. No DSL signal, no Internet or Email.
