The modem firmware cannot be updated/flashed via GoldenOrb/ROOter.silverwing wrote: ↑Wed Jan 15, 2020 6:55 pm is there a special way to update the firmware for the chip? or do i basically just go to flash firmware in r00ter?
The usual process requires placing the modem in an USB to M.2 adapter and using a Windows or Linux PC.
It may also be done via Sierra Wireless AirVantage platform is you have an internet connection. The instructions can be found on the link.

Signal strength looks fine, but "IMS reg state: No Srv" may not be.
Have your rebooted your router once or twice after the upgrade?
Have you done the initial setup (MBIM/QMI mode, APN), including the selection of the "generic" firmware?

Re: Sierra Wireless EM7511 Aggregation Issue
Don't forget a good power cycle when making changes trumps a simple at!reset or reboot button too. Sometimes stuff jsut doesnt seem to work, then I unplug it and plug it back in and boom, werkz.
But you may have not set the mode and firmware like Bill said, it may have defaulted back to a branded firmware image after you loaded up the new firmware image, putting you back to where you were a few posts ago.. The Sierras hold multiple firmware images per carrier and a slot for generic I think.
Verify with the command: AT!IMPREF? It should tell you what its using

Re: Sierra Wireless EM7511 Aggregation Issue
The"IMS Svr: No Srv" is normal for a router since it does not use voice and multimedia communications.
Curiously, was the generic firmware used with the AirAdvantage?
I would upgrade the modem firmware a second time. I find this is often necessary on the Sierra Wireless EM75XX modems to function properly.

Re: Sierra Wireless EM7511 Aggregation Issue
They default to the generic but in advanced settings you can choose to go with a wireless carrier.
I might try the wireless carrier firmware when I get the antennas delivered and setup to see which one might be better.
