I had an airlink g router that worked fine for 2 years and then broke down. Performance over 50 feet was variable and often degraded. I recently tried a Trendnet router with a new, improved, wider N-band. I now use an Actiontec 85 mega plug for my remote computers. It works great and uses existing house wiring. I couldn't get a cable in some places. Very easy to install - much more reliable than WiFi.
