It wasn't my laptop. It wasn't my firewall. Slowly every computer in the house lost it's ability to connect wirelessly. Finally the computer in the basement with the adapter matched to the router lost it's ability to connect. So the culprit must be the router's wireless capability. I guess that since it's a piece of hardware that I bought 9 years ago when we moved here, I should be pleased with a piece of electronic equipment that performed flawlessly for that long.
So today I installed a new router. The PC adapter for the old router worked with the new one but since it only connects at 11 mbps, I installed a new adapter on the basement PC. Everything is working just fine...hopefully for another 9 years.
