Hello,
The MTU value depends on your operator and his mobile network. Thus, I would suggest trying different values to see if there are improvements.
For SMS messages, can you perform the following checks and tests for troubleshooting?
- Insert the SIM card into your phone and check if you can send SMS messages from it. Ensure that the APN on your router matches the APN on your phone.
- If you can send SMS from the phone, manually change the VOLTE setting to ON or OFF in Network → Mobile, depending on your operator.
- If the issue persists, try setting the network type to 3G and see if it allows you to send SMS.
Regarding the SMS utilities, the correct syntax should be:
- password status
The word ‘send’ is unnecessary.
For the freezes, it’s possible that overheating or power issues are causing the problem. To test this, try placing the router in a different room, away from direct sunlight.
Moreover, if available, test the router with another PSU. Additionally, consider powering the RUTX50 via Passive PoE to see if it makes any difference. Power information for RUTX50 can be found here.
Also, it seems that placing the router horizontally has helped one of the users here. Thus, please try placing the router horizontally for the testing purposes.
Kind Regards,
