LM960A18 on AT&T AT COMMAND HELP

[greatness]

Greetings!

I've been troubleshooting connectivity issues I'm experiencing with my LM960A18 on AT&T's tablet plan. Modem has had magic applied to it, so its showing up as iPad Air (that I own). Download speeds have been horrible to say the least. I've performed speed tests on my ipad with sim installed and speeds reach 100Mbps down 20 Mbps up. Speeds in my NEXR5GO 20Mbps down and 3 Mbps up.

At first I thought the identity crisis would fix my problems, it hasn't. So I'm checking on firmware and possibly band selection in hopes of solving my problem.

Some AT COMMANDS work like,

Code: Select all

AT#GETFW

resulting in

Code: Select all

AT#GETFW

HOST FIRMWARE  : 32.00.004_2
SLOT   STATUS     CARRIER  VERSION         TMCFG  CNV
1      Activated  Generic  32.00.114       1023   32101006
2                 Verizon  32.00.124       2020   32101006
3                 ATT      32.00.143       4021   32101006
4                 empty    empty           empty  empty   

OK

Question 1: Does the firmware being set to Generic have an impact on speeds when my carrier is AT&T?

I've tried setting the firmware to AT&T but keep getting an error.

Code: Select all

AT#ACTIVEFW=1,3
ERROR

Question 2: Do I need to enter another AT COMMAND in order to be able to make changes to the modem?

Question 3: Would band locking be a better solution? If so, are there preferred AT&T bands I should be locking my Modem to?

Any help or ideas would be greatly appreciated.

1: Try AT#FIRMWARE=3

2: No "unlock" command needed to do it

3: I only like band locking when you keep getting a band that is garbage, knowing full well the other available bands are better, and it refuses to connect to the better ones.

Thank you for the response. I’ve tried using the following combinations:

AT#ACTIVEFW=1,3
AT#ACTIVEFW=3,1
AT#ACTIVEFW=1.3
AT#ACTIVEFW=3.1
AT#ACTIVEFW=3

They all return ERROR. I’m using the miscellaneous section found under Modem in GoldenOrb, should I send the commands using a different method?

I've been researching this a bit more. It turns out that the generic profile has all bands enabled by default, to include AT&T bands.

Should I focus my efforts in trying to BLOCK B5 or set B2 as my primary to improve my connection. Or should I try to enable the ATT profile first?

Definitely miss the old cable internet days

I just picked up the LM960A18. Mind pointing me in the direction of the spell you cast? Much appreciated

I just resurrected my AER2200 with LM960A18, it looked like from your other post you were successful with that spell, can you please point me in the same direction? Thanks!

You can read the current band via
AT#BND?
and how to use it
AT#BND=?
To set the generic band list, AT#BND? should look like this
#BND: 0,11,1A03B0918DF

Carrier Aggregation (CA) can be done via
#LCFC?
AT#BND=?
Modes
0 - GENERIC
1 - ATT
2 - VZW
3 - EU
4 - AU
5 - Sprint

Thanks Bill, I was thinking of a different kind of magic, related setting the IMEI part
