I spent few days with Basebox2 + Huawei ME 909s-120 and found the only working solution.
I use latest ROS 6.37.3 and 11.617.01.00.00 for Huawei
I tried preconfigured LTE configuration for my setup but LTE modem was not able to register to mobile network, signal was too low.
For me the only working config is WISP AP in BRIDGE mode
. In Router mode again Huawei could not register in mobile network.
Of course, I enabled mini-PCIe in System --> Routerboard --> USB.
If after restart LTE interface is not visible USB Power reset for 5 sec and system restart solves the issue.
Now when LTE interface is up and rinning I enabled
- DHCP client for LTE intterface
- DHCP server on default bridge interface
- added default route to LTE interface
- changed firewall to enable incoming traffic from LTE interface and masquerade outgoing traffic from LTE interface
After that I am able to use Basebox2 with Huawei PCI modem as wireless basestation in my house (inside and outside).
Still to be investigated how to send SMS or USSD requests in Mikrotik with Huawei modem. Need to know balance of SIM card and traffic usage.
Hope this will help somebody
All the best in new year.
