Provider not found using RUTM51

Hi,
RUTM51 with latest version of firmware and modem firmware only finds 2 providers and not my provider when scanning for providers. The SIM-card works perfectly in a RUTX11 with all 3 available providers are found. RSRP and RSRQ are Excellent and SINR is Good. When setting APN and code for my provider manually I get Data connection state “Connected”, but no data transfer and Internet is not working. See pictures. Antenna is the same for RUTM51 and RUTX11. The result is the same if I use 4G only or 3G/4G/5G.


Any idea what this can be? Is there a specific difference between the modems in the two routers or is it a software problem?

Hi,

Check if RUTX11 and RUTM51 connects to your provider and uses same LTE bands. Because it could be that RUTM51 doesn’t support band which your provider use and RUTX11 supports.

Hi,

Thank you for your suggestion, but both routers use B3 and B20.

Interesting, maybe try going to Network Selection page and set operator code (24214) manually.

Also, is data limit turned off?

Hi,
Also tested. I tried adding ice.net and code 24214 manually. Then I got connection but no data transfer. Data limit is turned off. Roaming is also turned off because I don’t want it to use Teleneor, but it works perfectly with speed 25Mbit up and down when using Telenor.

In case someone else gets the same problem.

I found a method to make it work, but if it’s a workaround or a solution could be discussed I think. What I did was editing WAN settings for mob1s1a1. In General settings I changed PDP to IPv4 (turning off Ipv6) and restarted the router. Then it connected, and scan also finds the provider.
