I have several cradlepoint IBR1100LP6 routers that use the MC7455 internal modems. The MC7455 went bad in one of the routers and was replaced with a new MC7455. Now, the router cannot detect the modem.
I contacted Cradlepoint who would offer no assistance since the 1 year warranty was up.
I thought perhaps the MC7455 firmware would have to be updated using the cradlepoint modem firmware. But I am unsure how to perform the update since the cradlepoint modem firmware is in a mdm file format (m_LP6_GN_02_20_03_00.mdm) and it cannot be performed via the router since it cannot detect the modem.
I also removed a MC7455 from a working IRB100LP6 to check what USBCOMP being used:

And, to check other configurations that I thought may show the problem:

Am I missing something here?
Does anyone have a suggestion on how to get this router to detect the new MC7455 modem (or how to update the new MC7455 firmware with the mdm file)?
