i first tried a WE826-T2 then a mofi 4500 and had decent results on At&t. both used band 2 for the fastest speed, here i have b2 12 and 30. b2 and 12 have the best speeds, b30 has the strongest signal but slow speeds.
i have the cba850 set up after following the guide posted here but it locks to band 30 so slower speeds that the mofi and WE826 because i could get them to either lock or default to b2.
i've read to post here on band locking and the Sierra Wireless MC7455 | EM7455 -- AT! Command Guide . i am not very good with a computer and only have a chromebook and cannot get excel to work. i'm wondering if anyone has the commands to set the cba850 to at&t bands 2 and 12 that they would share with me? i also need the band command at startup from connection manager to retain the locked band settings.
attached are some info from my setup

AT!BAND=0F,"B2 & B12",0,802

atterm

AT!BAND=00

Does

Code: Select all

AT!BAND=?

list "0F" you added?

Does

Code: Select all

AT!BAND?

respond with "0F" you selected?

If not, you type

Code: Select all

AT!BAND=0F

to set and then verify it is set to 0F

Code: Select all

AT!BAND?

before resetting

Code: Select all

AT!RESET

if the modem reboots will i lose this setting since i can't find when to enter the AT config script?
also what would be the command to lock to b2 and CA on b30, please?

AT!BAND=1F,"B2+B30",0,20000002

AT!BAND=1F

motrac wrote: ↑Thu Aug 27, 2020 7:38 am first thank you for all your help.
i thought you have to enter the command in the AT config script? that's what i can't find.
i have the modem set up to reboot daily @ 3am and this morning it was back to b30, ca 12 because i can't find the WAN interface profile to set the bands.
also
AT!BAND=1F,"B2+B30",0,20000002 returns error

AT!ENTERCND="A710"

Yipzy wrote: ↑Thu Aug 27, 2020 9:43 am You usually don't need to set a startup AT command but it appears your cradlepoint is overriding your band setting? The WAN interface should be in Connection Manager. You click on the LTE modem name then click edit button IIRC. It should be there though.

Did you issue

Code: Select all

AT!ENTERCND="A710"

before adding the B2+B30 to the list? If so, maybe you need to change 1F to 0D instead.

Yipzy wrote: ↑Thu Aug 27, 2020 12:23 pm Ah. Exactly what I suspected. Hopefully you got it all sorted out now.
