I wish I could be of help, but it'll take someone smart to help you.
If nothing else this will give you a small bump in the forum.
I've dreaded the day this happens to me as I'll have to relearn a lot of things to get it back on line. I've got a little $75 Dell laptop that's been running
www.beeweather.com for over 5-1/2 years now. I know one day it will decide to croak on me. My weather camera was located about 7 miles from the station...in our small town's downtown area, it died several months ago but I haven't attempted to get it back on line.
Anyhow, I'll be keeping up with how the re-establishing of your system works out.
Best wishes!!!
