Seems like it might be your WiFi router. Even if you have no issues with Internet with other devices. Are you using your own decent WiFi router or are you using the junk that ISP companies give you?
Not using an ISP router, it's a Netgear N600. Not the latest/greatest, but still sold and we replaced it at home with a Nighthawk AC2300. Remember- 2nd home.
I have an update. Last week I thought all the missing uploads were matched on WU and Ambient. On Thursday I realized that I had it configured with Ambient relaying data to WU, and changed the settings to do it independently.
Since 4pm Thursday afternoon (when I configured the base station) on Ambientweather.net there were 21 data blackouts on the 20th, 62 on the 21st, 61 on the 22nd and 29 so far today (with the 5 minute display intervals any single missing block could mean the transmissions stopped for 1 to 9 minutes, there were many periods with no data for 30-45 minutes too). I just went through all the data tables on Weather Underground for my station since then and there have been zero missed uploads.
I do not have it linked to WeatherCloud yet, just set up the account and will configure the base station later today. If that works with no problems then it'll confirm the problem is with Ambient's website.
So it is ONLY Ambient that is not receiving data. I will edit my post above for anyone dropping into this thread from the beginning.
