Problem with R11e-LTE modem

RouterOS General
1

Hello everybody!
I have 2 SXT R . One is with R11e-LTE modem and second one with Huawei ME909s-120 V2.
On Huawei ME909s-120 V2 i get from ISP ip with /24 mask and all works ok. But With R11e-LTE i get ip from ISP with /32 mask nad nothing work for me.
Why i get ip with /32 mask on R11e-LTE?

There is nothing bad as such about getting a /32 address. It depends on the internal interface of the LTE modem what is the address assignment mode. What does /ip route print say? And what exactly “doesn’t work”? Have you tried to swap the SIMs between the devices?

This is my output with yet another LTE modem (non-Mikrotik one):

[me@myTik] > /ip address print

These sim cards issued by ISP are used to build up L3 VPN to our local network.
i just don’t understand why i get /32 on R11e-LTE

Ofc :slight_smile:

The network value same as the address value looks weird but as the gateway in the routes is the interface name, it should still be OK. Even ping 8.8.8.8 from the router itself doesn’t work? What does interface lte firmware-upgrade lte1 upgrade=no say?

After update R11e-LTE firmware to v018 all works! Thx!
