I would love to replace my current solution with RB912 boards (and cases), if they can reliably support the Sierra MC7455 (regardless of mode - serial PPP is fine with me, as long as the device is supported without the need for me to debug it). Unfortunately, it seems there's a difference of opinions regarding the MC7455 miniPCIe being supported. Can someone authoritatively tell me if this combination successfully works?
I have a commercial multi-site application, in which I used "business-grade" cellular routers from a Canadian company (with a Franklin U600 USB 3G stick). Unfortunately, the so-called "business grade" solution has wifi issues (every 5 to 12 minutes, the device issues a "deauth" command, causing all streaming and file transfers to fail). The device is based on OpenWrt (for the MediaTek MT7620A wiSoc chip), and the wifi driver is obviously buggy. Support for the devices is non-existent, and I must find a solution for my customers, who are tired of having to restart data transfers.
I simply need a reliable 2.4GHz wifi cellular router, with at least 27dBm output (the 1 Watt of the RB912 is great), that supports an MC7455 without hassles... and that has a mature wifi driver and stack that isn't experimental.
