Ahhh okay. That makes more sense. I'll right up a quick crash course for you on this after work and post it here

Firstly, I am soo sorry I forgot to get back with you on this. I've been extremely busy the past few weeks.

Anyway if you still need this information, here is a list of all the band masks that I currently have.

List of bandmasks

B65     0000000000000000        0000000000000001
B66     0000000000000000        0000000000000002
B67     0000000000000000        0000000000000004
B68     0000000000000000        0000000000000008

B71     0000000000000000        0000000000000040
B72     0000000000000000        0000000000000080
B73     0000000000000000        0000000000000100
B74     0000000000000000        0000000000000200
B75     0000000000000000        0000000000000400
B76     0000000000000000        0000000000000800
So you wanted these 3 bands together (B5+B13+B66). You take their bandmasks and add them together. Keep in mind that this is hexadecimal so letters can (and will) get involved at times when added the bandmasks together.

Code: Select all

B5      0000000000000010
B13     0000000000001000
B66     0000000000000000        0000000000000002
Your custom bandmask would look like this when they are all added together. This line of code is ready to send to the Sierra Wireless modem and in your case the EM7565. B5+B13+B66 is a pretty easy one to do.

Code: Select all

at!band=0A,"Custom",0,0000000000001010,0000000000000002
The part where it says "Custom" is going to be the name of the band and you can change this to whatever you like.

When using these commands make sure you change the at!band=** index to the numbers that you are not using ex. at!band=0A

Here are some examples of other carrier's bands and what adding their bandmasks together looks like.

You would be correct. Mine did not reflect one of the bands cause I believe the EM7565 does not support all of the Sprint bands.

When I run at!band=14,"B12",0,0000000000000800 I just get an ERROR
I got the same error but derived a solution based on info on menandmodems.


This worked to lock my mc7455 to B12 (ATT-M).

You want to associate an Index number (or profile)'04' that is unused by the modem FW. 03-05 are unused on my MC7455.
at!band=? shows the profile or 'Index' numbers of the bands currently in use by the FW, including custom Index numbers you created. You can use this cmd to make sure 04 is not used.

Enter this:
AT!ENTERCND="A710"

Next, this cmd below associates index 04 with B12. (04 was not in use on my MC7455). "LTE B12" will appear as a narrative or description for this index number (04).
AT!BAND=04,"LTE B12",0,800

send reset.
AT!RESET

After it resets, you can send the following band cmd to use Index number 04 to force and lock to B12.
AT!BAND=04

Send reset.
AT!RESET

After it resets, B12 will be locked if B12 is available and the signal strength is sufficient. Some folks say you need to power cycle but I did not find that to be the case with the WE826/MC7455. It's working here.

As previously shown in this thread:
To unlock just do:

AT!ENTERCND="A710"
AT!BAND=00
AT!RESET

Hey guys. Forgive my ignorance but how are you guys determining which bands are best in your area? Are you locking to one band at a time and doing speed tests? I've got a em7565 and so far performance is pretty good for what I'm used to (DSL). I get around 50Mb down and 10 up. I was hoping CA would be controllable on the modem side but from what I'm reading the carrier has to allow it as well. One other fact, the tower closest to me has only been live for about a month and a half so it doesn't even show on cellmapper yet. Thanks for any help.

You can figure out where the cell tower is and then use google earth to basically figure out what angle from your house is best to aim your antennas. Where are your antennas currently mounted and how high are they and how far are the antenna cable runs

Hello,

I just switched from a mofi 4500v2 to a WG3526-P + EM7411 CAT-7. I know this thread is titled for MC7455/EM7455 but was hoping the AT! commands are the same with 7411. With the mofi locked to B4 T-Mobile I was averaging 30-32mb down (a 3.5 miles on a hill from tower, as high as 55mb as lower as 10mb). With the same outdoor antennas (unmoved) and the WG+7411 i'm averaging 3-5mb down (its using B66 and/or B12). The switch was due to connection issues at peak PM usage hrs and wanting band 66+71 with better CA.

How do I lock to bands B4,B66 and B71. Zero background in programing.

Based on reading I this thread I think the below might do bands B4+B66 but was unsure on B71? Thanks in advance for any and all help.
AT!ENTERCND="A710"
at!band=11,"B4",0,0000000000000008
at!band=13,"B66",0,0,0000000000000002
AT!RESET

Did you set the TTL settings? Which plan and carrier? You may be getting hit with speed throttle due to hotspot cap, that the MOFI was set to mask with TTL changes.

Thank you for taking the time to try to help. I redid testing and it came up but still lower. pretty sure due to the band for SCC (if I can lock out b12 it should force it to use b4 or b71, but b4 is a strong signal)

Yes TTL is set to 65 (same as before), have been running the mofi for 3+ years and regularly hit 350gb+ of use without issues on T-Mobile (I have 6 lines with t-mobile but use just one of them for wifi, if I ever did hit a slow down I'd swap in another though). I think it's due to it using band b12 for the CA SCC1. The Mofi was locked to just band b4 20hz (best speeds by far and I locked to avoid it switching to band 12 on occasion, which is a 5hz slow band).

The new modem is great it picks up band 4,12,66,77 really great and 66 is decently strong signal (mofi only had 12/4), signal quality has always been an issue due to trees with RSRQ of -15 to -17 (but hasn't changed any from prior). I ran a bunch of tests with the mofi at noon on a weekday and over 20 tests I averaged 32mb down, the same tests with the new Sierra (both over Ethernet) averages about 17mb down (some lower / some higher but average of 20 tests and same speed test site I used for mofi). Reason for switch was I was getting disconnects which I'm pretty sure was b4 congestion related (I live way out but in 160 home development on 5 acre parcels and this is the only internet besides SAT or copper, both of which are aweful for speeds), with the new band 66 I'm still slow after 6 on weekdays but it stays connected (YES!!!!!).

I do think the Mofi made setting up antennas nice and easy as it it auto updated the readout strength/quality db (plus a signal strength readout like a phone) every second on one screen and that allowed me to diel my 26db Bolton laser pointer antenna and wide band aux antenna in to the strongest tower for b4 (mofi didn't have band 66 or 71). Based on below the same tower (3.5 miles away) has 66 though (best I got for b4 was mid -80s for DB).
