Hi,
Thanks for your input. I am 99% sure it is not a local network problem. It works 100% when I use Davis' Weatherlink to do the uploads which I was doing for years before getting the WiFiLogger. I agree with you that problem is almost certainly with the firmware in the logger. I have an E-mail from Wojtek and he said he was going to look into it.
Your questions:
The main router is the one provided by Verizon. Not sure what the model number is; the home page just says Fios by Verizon. The FIOS provided IP address is 71.115.211.XXX. It's DHCP. On the lease time, frankly I don't know. The IP address has been unchanged for years, so I am not sure it matters. If I am not mistaken, all devices on the network are set for DHCP, *except* one, the computer closest to the router, which runs 24/7 and has Ethernet connection to the router. It has port forwarding in the router for incoming HTTP packets (I have a small "webserver" ab2tc.com running on it. It's mainly used so I can host various stuff,like pictures and screen shots, that are too large to send in an E-mail.) The router is not set for daily restarts as far as I know. Full disclosure: My wife is the real expert on networks and typically handles setting things up on new devices. She works as a network administrator for our local (fairly large) school board and she is not back from work yet. Our network has really exploded in size in recent years with doorbell camera, web accessible outdoor lighting, etc., etc. No, the fridge is not web enabled yet.
The closest WiFi access point is a NetGear Horizon. The signal from it is *much* stronger than the one from the Verizon router in the basement. I use Vistumbler on my laptop to check these things. They both have the same SSID. The connection to the main router is via coax, a MOCA bridge and a short CAT5 cable. Nothing on the network is mesh or WiFi extender. I have a $30 extender collecting dust after trying it for one day.
The WiFiLogger is set up for DHCP and is currently 192.168.1.203. I do not think there is a reservation on the server for it. All other functionality on the logger works 100%. E.g. I can have Weatherlink on any computer on the LAN and have it working 100% including CWOP uploads if I turn that on (and turn it off in the WiFiLogger). Actually, I have not tried that for a full 24 hours after installing WiFiLogger, but since the live data on the WiFiLogger's home page works 24/7 I would expect the WeatherLink CWOP uploads to work 24/7, too. The firmware version is 2.34, which is an upgrade since we first installed it.
I think that answers most of your questions. Sorry if it is a little disorganized. I am not a professional forum jogger.
