WE826-T2 and EM7565 - No Modem Present?

Post by thejohnfist »

Had this set up for about a year now. Today we had a storm roll through, no big deal, storm blew off and everything was still working. Then we had a power outage that maybe lasted 30 seconds. This has happened before with no issues.

Today however, the internet didn't come back. Router still seems to operate, and it detects the modem:

However, on the Network Status page, there's No Modem Present at the top, and no data connection. Can't send commands to the modem at all.

I tried reseating the modem and connections. No success. Is it the modem that's dead? Router port? Sim card?

Any help would be great... Thanks

For anyone who checks this in the future -- I reflashed the router. No change as far as the modem was concerned.

I pulled the modem and tried connecting it to my Windows 10 PC with a USB adapter so I could flash new firmware on it. So far, no luck with that. Not sure yet if I'm doing something wrong or if it's dead-dead.

Will update later.

Did you download and install the Sierra software for Windows (drivers)?

I did install the drivers. Not sure what's supposed to happen though. I install the drivers, then plug the device in (device seemingly can't be found on my PC, no notifications or anything in the device manager) and run the firmware, only to get "device not found" error.

When you plug in the USB adapter, does it show any lights, or does the PC make a sound that it normally makes when a USB device is plugged in.

Also, under the Device Manager do you see any reference to the modem.

The light on the USB device lights up (I tried multiple ports, USB2 and USB3) but the computer didn't seem to notice anything was there.

The only mention of anything Sierra Wireless was something the drivers installed (it was present regardless of the USB device).

Giving up on this one. Going to order a MC7455 and hope it works out.

Which version of R00ter did you use? Is it newer than the one you were using before?

It was newer, yes. I'm pretty sure the modem is dead. Put in the new modem and everything went right back to normal.
