Dear all,
we recently made a purchase for a RB411U with a Huawei ME909u-521 mini-PCI-e card, in order to use LTE network through the RouterBoard. We have some difficulties getting mobile network information from the router, following list summarize our questions:
- Is it possible to read the frequency (EARFCN) for this mini-PCI-e card ? or is it a limitation of the board itself ?

- Which mini-PCI-e would you recommend for cellular network (LTE or other) connection ?
- The Scanning function for LTE connection seems to be unstable, and provides no detailed information about scanned cells and networks, do you think this is software or hardware related ?

- We have used the latest version of RouterOS, 6.40.1, and tested older versions as well, but we have not seen any difference in outcome, would you recommend a specific software version for our system ?
Many thanks in advance.
