I have a 2 year old Toshiba Tecra M3 which has been giving me the following problem for about a year, maybe more. I'll be logged in to the internet using the built in wireless, and suddenly I will lose my connection. The Wireless Network Connection Status window will show me as connected with excellent signal, but my web browser (Firefox or Internet Explorer--happens with both) will give the Unable to Connect message. (Meanwhile my husband will be connected on his Fujitsu LifeBook and be having absolutely no problems.) The only way to re-connect is to re-start my computer. Sometimes a few days go by without this happening, and sometimes, like today, it happens multiple times. I have not been able to pin it down to a particular sequence of keystrokes, whether it had been hibernating, or anything. It appears to be completely random. Any ideas?
