Monday night it was below freezing here with sleet and ice - something that rarely happens and causes lots of problems, like car wrecks, when it does. My internet connection died and the ISP declared my problem was widespread and was being worked on. Okay.
Tuesday, I was still unable to connect to the internet. After an hour or more dealing with the ISP's tech team, we were able to get my daughter's computer to connect to the internet if it was directly connected to the ISP's modem. We determined that the router had died. So, we went to the store and bought a 5-port work group switch because the guy at the store told us that was what we needed to replace our dead router. We could still get my daughter's computer connected to the internet but I kept getting a 169 IP address, unidentified network, etc. The ISP tech people told me that as my modem worked, the failure of my machine to connect to the internet was not their problem.
Wednesday, I replaced the cable from the switch to my pc but was still unable to connect. I spoke with the manufacturer of my PC and the manufacturer of my new switch and neither one were able to resolve my issue.
Thursday I was sick - lost 5 pounds - and had to be in bed all day. Actually, I've been doing pretty good the last month but I had a piece of pie and some chocolate at the office Christmas party Wednesday and that much sugar made me sick.
Friday I spoke to a little weirdo guy in India about my 169 IP issues. Apparently this is a big issue these days and has something to do with a patch Microsoft has issued that has caused more problems than resolved. Anyway, as I was getting the 169 IP error, it was assumed that my poor little PC had become another casualty. But, the little weirdo guy in India actually listened to what I said. My router had died, I went to the store and they sold me a work group switch to replace my router. We were unable to get both computers to work at the same time.
So, do you know what the problem was?
