Hello,
i've just put my hands on a NR7101. Installed openwrt and everything is ok.
However, since my internal router is another openwrt machine, i'm trying to understand if it is possible to get a "ip passthrough". I'd have bridged the modem connection with the lan connection (or better, with a vlan), but i'm stuck with the fact that the modem connection is managed through modemmanager, so i think in this form it can't be bridged.
If i bridge the device itself, i'm no more able to setup the connection.
So am i missing something? 
And bonus question: is it possible to see the real bands the modem is connected to (also with carrier aggregation) and not only the available/allowed ones?
thanks
