Hello Radu

12000053

I have two Fritzbox Routers 7170 with firmware 58.04.77 and 7330 with firmware 107.06.20

No Problems

Hello all,

my FritzBox 7340 refused to talk with the uRadMonitor, it showed up with it’s local IP and that was all. The moment I connected an (very) old 10/100 mbit switch between the router and the uRadMonitor I could ping and see the local webpage.

To make it work, I also disabled ‘Teredo filter’ and did a ‘port 80 forward enable’ for the uRadMonitor.
The setup is not ideal because I have to reset the router, switch and uRadMonitor (in that sequence) on a regular basis.

Hello everyone,

since a few days I have the uRM (ID:12000059) connected to my network and since today also on the map.
It gave me a hard time to make it talk with my FritzBox router.
The solution seemed to place an 10/100 mbit 4-way switch inbetween the router and the uRM.
The uRM uses TCP on port 80 which I forwarded in the router.

Now I’m getting a hard time again as I try to include my Arduino with W5100 ethernetshield for my home-automation project in my network. It also uses port 80 and used to work like a charm in my network with the FritzBox. To make it work again I changed the port to 8080 in my sketch ( EthernetServer server(8080); ) and again the home-server works like a charm when I type : my_fixed_IP:8080/page_x . No problems with it.

The problem now again is the uRM which seems to do not like another server on my router, it refuses to talk normally to the router and I have to reset the uRM every few minutes to get it talking again, after a request to my home-server the uRM hangs again and needs to be disconnected from the powersupply temporary to reconnect.
So for the moment I disconnected the home-server while I try to find a solution.

Am I doing something wrong or is it firmware or hardware related ?
Any suggestions what I can try to do to make them both talk at the same time with the router ?

Tnx Steve, that was a helpfull hint.
I changed the router setup and connected the uRM with portforwarding rules from port 3837 to port 80.
Now I can reach my Arduino server as before in a browser without adding a port number.
From the outside world I can access the uRM with my_fixed_IP:3837 .

Right now when I connect the Arduino-server to the network and access it with a browser, the uRM ‘crashes’.
I can see on the local IP address 192.168.178.108 that the uRM went offline.
On https://www.uradmonitor.com/?open=12000059 the ‘Last instant readings’ does not update anymore.
5 to 10 minutes later the uRM reconnects to the network and I can connect again on 192.168.178.108 and a few minutes later the map will give a online sign again and the ‘Last instant readings’ updates again every minute.

As long as the Arduino server page is opened in a browser it lets the uRM ‘crash’ again and the sequence repeats itself as long as there is arduino-server-activity. In a browser the webserver site updates itself every 15 seconds with XML for time_information and some settings.

To me it looks like that the server traffic lets the uRM crash. But it may also be possible that my router goes nuts, i just do not know what and why this happens.

Radhoo, I had a lengthy telephone conversation with my I.S.P. after returning to the factory settings and thoroughly testing, the problems continued. The conclusion was that my FritzBox had severe problems. Probably only in a network with DHCP + fixed IP numbers together, what resulted in the repeatedly lost connections.
In a few days I’ll get a another router/DSL-modem. I will report the results here asap.

The new router, a Fritz.box 7360 solved all the connection issues with the uRM. It is now connected directly on one of the 10/100 Mbit router-ports and works perfectly together with more servers on my LAN.

It is guessing about what was wrong with the old modem/router. Maybe problems with DHCP and fixed IP’s together or a problem with correctly synchronising with the 10 Mbit ENC28C60 of the uRM, or else IP4/IP6 issues.

Whatever it was, everything is working now perfectly.
