Hi all. I have purchased a new RUTC50 as a replacement for an old RUT240 and immediately started to have internet connectivity problems with it using the internal 5G modem. The 5G/LTE NSA link aggregation works as expected and speeds and signal levels are satisfactory. In spite of this, every couple of hours of continuous uninterrupted service I get another few hours of modem throttling. That is to say, the internet connectivity stops for a few seconds, sometimes a minute or two, then it resumes for another minute or two. After a few hours, the modem recovers and works perfectly for another few hours. In the logs I get a long series of “IPv4 connectivity started to fail / restored” entries or “DNS resolutions started to fail / restored”. I set up ping reboot as a workaround but with little success. I have also reviewed similar topics in this forum but they give little help. One workaround solution suggested by others (for a different model however) was to use the modem in a passthrough mode which I am reluctant to try. I also set up the wifi wan interface (wisp mode in other words) to try the router part itself with a different wifi router (huawei) as the internet source to see if the problem indeed lies in the internal modem. The wifi wan is now working fine which suggests that my problem really lies in the internal modem/mobile interface. Finally I have to add that a similar problem started to appear with my old RUT240 a few months ago after one of the firmware updates which was one of the reasons I bought the new RUTC50. The difference in behaviour is that with the old router the internet connection stopped completely until the modem was restarted while with the new RUTC50 there is this throttling and also better log documentation.
Any help would be welcome as I don’t want to start to believe that one of the most expensive industrial routers on the market can be that worthless…
