Thank you galfert for your clear description. I will not soon forget about keys. Station is back online. BTW, the reason I changed VWS's password was that the station seemed to have gone offline coincident with my changing my web password. Alas, that must have been dirt in the fuel line.
Are you up for helping me get my webcam (re)connected. It worked solid for a year, then things seem to have gone south. It's associated with my PWS, uses ftp to webcam.wunderground.com with my username and web password. I continually get "incorrect username or password".
