What changes in RouterOS 7.23.6 and 7.24.3?
These versions introduce a specific regression that disables the LTE interface on the hardware models listed in the advisory. The issue does not affect other routing or switching features, but it completely blocks cellular connectivity on those specific devices. The MikroTik announcement on the forum clearly states that the interface becomes non-functional after the upgrade, rendering the router unusable for LTE traffic.
Who should update (or not update)?
Only administrators managing the following models should refrain from updating: RBSXTLTE3-7, EC25-EU&KNe, EG25-G&KNe, EC25-EU&SXTsq and EG25-G&SXTsq. If you own one of these devices, do not install versions 7.23.6 or 7.24.3. For all other MikroTik router models, the advisory does not report specific restrictions related to this LTE issue.
How to update (or remediate) safely?
If you have already installed one of the problematic versions, follow this procedure to restore LTE functionality:
- Downgrade RouterOS to version 7.23.5 or 7.24.2.
- Update the modem firmware by running the command:
/interface/lte/firmware-upgrade lte1 upgrade=yes. - Reboot the router.
If the router does not have an internet connection to download the firmware, manually download the package from the link provided by MikroTik, upload it to the router’s Files list, and reboot the device to install it. Specific firmware packages are available for RBSXTLTE3-7, EC25-EU&KNe/EC25-EU&SXTsq and EG25-G&KNe/EG25-G&SXTsq via the download links indicated in the official advisory.
