A few months ago I had to setup a home office and decided I would take the opportunity to upgrade my home network. My Linksys BEFSR41 Etherfast Cable / DSL Router had never given me any problems and so I decided to upgrade to the Linksys BEFW11S4 Wireless-B broadband Router. I now have everything working reliably but getting to this happy state and resolving the problems took a lot of luck and in the end the solution was far from obvious. Judging by the bad reviews on Amazon and elsewhere it appears that many people have been unable to fix similar problems with this device. Below is my description of the problem and a solution that worked for me. Hopefully this will help others, but as always, your mileage may vary!
