Here is an update on my issues. I have flashed this modem with a linux and windows machine and I am still getting low power mode. I have gotten it out on a windows pc with a at+cfun=0 command. I can't ever get it online with a WE826 from thewirelesshaven.com. I have tried everything I can on this.

Jim,

I will give that a go.

current carrier name: mismatched
current config name: mismatched

Says this to when you do a IMPREF command.

I tried to do a reset and it said there are now saves nor did it change anything. I did both at!RMARESET=1 and at!RMARESET=3 neither worked.

When I run a at!gstatus? I get low power mode and no signal read outs. I have searched and searched around. I first tried to flash the firm where with a windows pc with a usb adapter. I then installed Ubuntu and flashed it with a linux files. Still the same issues. No dice.

Thanks Jim for your quick response. I have been sending over lots of people to buy from the store today! More to follow shortly!!!!!

I am fixing to build my latest modem build and was wondering if there is a firmware for pi 3 b+ that has the EM20 drivers on it?

And here's some more info on AT commands.

Also, don't forget to disable 3G by setting the modem to 4G only ...

If you lock in a single band properly, there's no way for the carrier to switch your modem to another band. Evidently you've still got two or more working bands enabled in your modem, that's why it keeps on switching you. Make sure to calculate those band parameters properly and send the commands ...

AT- Command is the line before the big window. You just put in your commands in there. The read out will be in the big window.

I have a question about carrier switching bands at night to Band 4. During the day it will switch to Band 2 which is must faster for me. I have locked in band 2 and band 12 and it will still pull band 4 on me. Is there a way to make this stay on band 4 or is the carrier switching me to another tower ...
