Last week, I had to reinstall Windows XP. After that, I had many problems, one of which may have been related to the XP reinstall. In particular, I found that I had to establish a new wireless network. Unfortunately, I didn't take exact notes of what happened and what I did, but I think I let Windows (or Linksys) detect and set up the network. Linksys then gave me a new SES network name and passphrase. I was soon able to connected to the Internet and all was well (until the next day). Whereupon my wife, who had previously used the wireless network, began to lose her wireless connection to the new network "often". When she tried to reconnect, her computer (a Mac) usually asked her to supply a passphase. This was annoying because the passphrase was always long and irregular, and different from time to time. Whenever she lost her connection, I could get her on again by pushing the lighted Cisco Goldem Gate logo on the front of the Cisco wireless router. Typically, (if not always), that seemed to generate a new wireless network name and sometimes a new passphrase. Soon, she was trying three and then four recently generated passphrases to reconnect. Now our collective passphrase list is up to five and I don't know what to make of that. So my question: what happened when I reinstalled Win XP and how do I get back to a situation (a) that doesn't drop a couple of times a day, and (b) doesn't create new network names and passphrases when it drops. I suppose I've brought this on myself, but I don't know why or what to do about it.
