Wireless Joint

I am happy to say Calyx has worked reasonably well except for streaming video.

Have been running Calyx 4g LTE for about 1 month. 4.8 miles away to somewhat tree obstructed tower, getting 20-40mb/s down 3-5 mb/s up with external antennas. Speeds can be quite variable. It will get over 60mb/s down in ...

Depends....

If you mean from one Sprint branded device to another Sprint branded device in order to swap to the new one, like one Sprint hotspot to another Sprint hotspot, then no. The SIM cards are provisioned to the device its activated in.
In that case you simply call Sprint and tell them that ...

That is the exact route I went, started with the r850, then r910 and never satisfied with the device serving my home internet. I went with a wg3526, but I recommend the 826 if you dont need PoE to power it. Mine is on the room in an enclosure.

I do, though, recommend using a Quectel modem (or a ...

I was incorrect, B41 is available on the EP-06

But you may want to check if your using B41, Modem->Network Status I believe

Or At command AT+CSQ I believe


The EP06-A does not have Band 41. Only the EP06-E and then it lacks a lot of the other bands. This is the reason we stock the EM06-A which ...

Also the r850 can pick up B41, the Quectel EP06 does not I think I read. Sprint Band 41 is the speedy DL channel, but very capped upload, whereas the FDD, lower, channels (25,26) CAN have better upload speeds but dont match B41 DL speeds.

Any idea of MBIM vs QMI would make any differences on sprint? It is currently using MBIM.
Also wondering if the TTL settings makes a difference, currently set at 65.



After a bit of research here are the three modes available on Quectel modems (EP06 and newer).

AT+QCFG="usbnet",0 - QMI/PPP ...

I prepared an Excel spreadsheet to assist in programming bands and/or a group of bands, on the Quectel modems.

As with all material on this forum, use at your own risk.

I have plans on including other Quectel modems when time permits, as well as a quick tutorial for commonly used AT Commands for ...

This thread seems pretty dead but I just wanted to say that I found a serial terminal under the metal shield nearest to the battery connector. Red is TX and black is RX and this is the boot log: https://pastebin.com/Rh2FAeJ9

It disables all serial input but if you hold down the wps button until the ...

TL:DR version: Yes, suggestions at the bottom.


Long general slightly noobie version:

So, lets Clarify...

The Sprint based devices do not allow SIM swapping. But! That is a completely literal statement. SPRINT based, official Sprint device, firmware will not allow you to use a SIM from another ...

I had a power outage this weekend, when the power came back, my EM06-a would not connect to verizon.



A power outage may have corrupted the modem's NVM (Non-Volatile-Memory).
I would reset it and try both QMI and MBIM modes.

QMI mode
Copy and paste each command one at a time, and make sure ...

I have one of these on the way to see if it works. It should plug on to the "testing port" and allow for external antenna.

I am currently using these antennas:

Band 41 has a 'decent' range. Good antennas should pick it up beyond 3 miles pretty easy, but the hill could prevent it.

That ...

Just in case someone else is having the problem after scouring the forums for a similar problem I think I have found the fix. I'm not sure why it worked but going into Goldenorb network settings then SQM Qos and changing Queue Discipline from the default fq_codel to cake and the queue setup script ...

Do you know what APN it was using? What plan is it run on Sprint with?

Ill make a guess at your APN...
Run the following AT commands:

AT+QMBNCFG="AutoSel",0

then

AT+QMBNCFG="Deactivate"

then

AT+CGDCONT=6
AT+CGDCONT=5
AT+CGDCONT=4
AT+CGDCONT=3
AT+CGDCONT=2,"IP","r.ispsn"
AT ...

Probably want to also re-do the cgdcont commands:


AT+CGDCONT=1,"IPV4V6","r.ispsn"
and
AT+CGDCONT=2,"IP","r.ispsn"
go ahead and add
AT+CGDCONT=3,"IPV4V6","otasn"


Some like to make the otasn one as AT+CGDCONT=1, then the others #2 and #3.
I'm not sure it matters.

They are called pdp contexts. Basically you are giving the modem the list of APNs it is allowed to use, as well as the allowed protocols to use with them.

Tmobile has been aggresively working on towers, messing with a lot. It will take repetitive calls to cust service asking wth is going on with signal and towers to get some answers. It's about all I've been able to get.

I started using this modem two months ago and wanted to compile a guide to all of the tweaks and hidden features I've discovered buried in various dusty corners of the web that may or may not exist by the time you're reading this 8-) .

WARNING
You will be going into debugging menus containing ...

Hello think this is a relatable post viewtopic.php?t=3448

Most modems I've used on old Sprint plans that are now T-mobile, lately, including the Calyx SIMs, needed the modem imei to match the hotspot the SIM came in. (SierraKeygen bkerler might be a good think to lookup)

You can also give a go at calling Tmobiles BUSINESS support line and tell them your ...

Got my Tmobile sim yesterday. Stuck it in my LT18 and had video throttling. Disabled TTL settings and fast.com shows 90Mbps. Re-enabled IPV6 and still good. Also changed APN back to fast.t-mobile.com as changing to b2b.tmobile.com didn't help

So my settings are:
identity crisis
fast.t-mobile.com ...

Set your APN to ipv4 only.. it's a setting under modem->connection profile. If needed, disable the modems ability to auto load apn's via at command.

For local, that's under network->interfaces->lan
And network-> dhcp i think.

Any particular reason to disable ipv6?

Might need a modem firmware update. Tmobile has changed a lot in the last year.
