I have been using Lynksys BEFW11S4 version4 for 2 months w/o major problems. During the pass 2 days my router can't connect to the internet wirelessly. But it works when I plug the output cable into my notebook. This is the only computer I use and don't have any other networked computers. I am using earthlink as my ISP and run Toshiba cable modem model PCX1100. Before, when I used it wirelessly, I would also have ocassional drops and reconnects and signal strengh would fluctuate and recover. This is another question that I want to find out how to resolve. Rightnow my main concern is to get the router back up. Please be easy on the technical stuff, as I may not understand too much technical stuff about networking. I am a newbee at this. Thank you LuisCarlos
