OK, for whatever reason...this is what worked.
After pinging successfully (previous post)...
(I'd already disabled WEatherlink uploads before pinging...)
I disconnected the ethernet cable from the back of the WLIP unit.
Disconnected external power, then removed batteries.
Waited about 5 minutes then reinstalled batteries...reconnected the external power supply.
Once all readings were being displayed again, I reconnected the WLIP ethernet cable.
Restarted WCat and now, for whatever reason, everything is happy again!!!
Now....onto trying to get custom alerts to work. I have the same issue as before...user text will not hold once entered.
I'll work on that some more...that's another thread though.
