I’ve a huawey K3806 internet key and a RB411U routerboard (firmware v5.21).
From the supported hardware list (http://wiki.mikrotik.com/wiki/Supported_Hardware) the K3806 board is supported.
The router recognize the key as visible in the following image:
but when I try to communicate with the modem using a serial-terminal it doesn’t respond, also the PPP interface can not communicate with the modem.
When I type a character in the serial terminal window nothing appear, nor “OK” response from AT commands.
Could anyone help me?
An update:
Ros 5.21 recognize the data card but not communicate with it
Ros 5.18 communicate with it after a downgrade from 5.21 but when the power goes down and the router reboot then the data card is not regognized
The only way to resume back the internet key is to upgrade the RouterOS to v5.21 and the re-downgrade to 5.18.
Any idea? Actually the system is inusable.
