I upgraded the firmware to 2.1.0 and ever since I have had issues. The first one is that it seems to disconnect from WU on a daily basis, sometimes for only 20 minutes or so and sometimes over 2 hours such as it did last night. The other issue is it doesn't update to WU as often as it did which makes the rather dismal wind speed data even less accurate. Near as I can tell it updates every 20 seconds now whereas before it was around every 8 seconds. I would like to revert back to 1.0.9 because that one worked quite well but I can't get to that anymore on Ambient Weather's web site and didn't save a copy. Hopefully they will fix this soon but in the mean time, to anyone thinking of upgrading your ObserverIP firmware to the latest and greatest, remember these words of wisdom from some great philosopher who said: "If it ain't broke, don't fix it".
