Hello,
We installed 38 RUT200 2G/3G/4G, but we have seen the signal is bad for the 4G so the network not work. If we force for only 4G in config it’s the same. So we have 2G/3G in config and the customer have between 2 and 8Mbs, not good.
If we make a test with a phone with 4G we have 40Mbs and 3G we have 12Mbs.
We tested to change the antenna and it’s the same.
Have you any idea why is it to bad ? Have you a specific config to improve the signal ?
Thanks
Regards
Hello,
Firstly, to help optimize the mobile signal strength and connection quality, I would recommend reviewing signal improvement recommendations available on our wiki page below.
Note: Ensure that both mobile antennas are properly connected and securely fastened.
Secondly, for testing purposes, you can try locking the modem to a specific, most stable LTE band available in your area. This potentially can help to improve both signal quality and data throughput. You can find more information about band locking configuration here:
Additionally, using higher-gain directional antennas aimed towards the nearest operator’s base station (if its location is known) can significantly improve signal reception. Alternatively, if feasible, testing with a SIM card from another provider with better LTE coverage in your location could also be a good option.
Lastly, could you please check the internal modem firmware version currently installed on your device? You can find this under Status → System on the router’s WebUI.
Looking forward to your feedback.
Best regards,
Hello,
We do multiple test and we think there is a link between the authentication PAP and the IPV6.
If we connect the router in auto mode (2G/3G/4G), PAP authentication and the option IPV6 setting “delegate IPV6 prefixe” it not works with 4G. But if this option is disable the 4G network don’t work with the PAP authentication.
What do you think about this config ?
Thanks

Hello @chc,
May I ask which APN you are currently using? For testing purposes, I would suggest
temporarily setting the PDP type to IPv4 only (if not checked yet) and seeing if that gives an improvement.
Additionally, could you please check and let us know the internal modem firmware version currently installed on your device? You can find this information under Status → System on the router’s WebUI.
Lastly, it would be helpful and appreciated if you could provide a screenshot of the Status → Network → Mobile page, with any sensitive information such as public IP addresses, IMSI, ICCID, or cell IDs hidden.
Best regards,
Hi there,
Thank you for the update and providing a screenshot.
The first thing I’d recommend is considering an upgrade to the latest firmware version, 7.15, or at least to the previous stable 7.14.3 release.
Also, could you please clarify from which firmware version you initially upgraded to 7.14.2? If it was from 7.14 or 7.14.1, I trust you followed the mandatory update instruction outlined in the official firmware wiki page or here on the forum.
From the screenshot you shared, it seems the LTE signal is excellent, and the other signal parameters are also quite good. I’m assuming you might be using a better external antenna now, could you confirm what type/model it is?
Additionally, is band lock currently enabled? If so, it might be worth disabling it temporarily to see if the modem can connect to other available bands with higher capacity or better performance.
Lastly, could you confirm which APN is currently being used? If your SIM requires authentication (such as PAP or CHAP), please double-check that the credentials entered are correct and match those provided by your network operator.
Feel free to share these details – it’s very appreciated and helpful.
Best regards,
Hello,
Sorry i’m not the installer technician, I don’t know what is the version before the 7.14.2. Ok I will upgrade to 7.15.
For the antenna, it’s the default antenna in the router box, how can I send you the model ?
No the band is in auto mode :
Hello,
To complete my answer, we have a PAP authentication with 4G, and we think each 24h the router reboot or re-authenticate with the account because in the graph under you can see the link down. Why ?
Is it a problem with 4G and PAP auth ?
For each router it’s not the same hour, but it’s 24h too, and the customer the the break down during 20min approximatly.
In log we can see this :
