Nice……It’s great that everyone keeps adding more cool stuff to do with the LBR20.

FYI: Added the code boxes…..good point!

Here are some additional useful commands:

To disable Cell Lock:
echo -ne "AT+QNWLOCK=\"common/4g\",0\r\n" | microcom -X -t 1000 /dev/ttyUSB2

To query Cell Lock status:
echo -ne "AT+QNWLOCK=\"common/4g\"\r\n" | microcom -X -t 1000 /dev/ttyUSB2

You can also lock multiple cells using the ...

I’ve put together this guide to help anyone wishing to Cell Lock to a specific cell. Please use at your own risk and know the pros and cons of cell locking before jumping in. 🤓

Here is a roundup of the providers/data plans I’ve tested on the LBR20 during the past 3 months:

By Price:
1. $15 Verizon Tablet Plan: Magic & TTL
2. $15 MetroByTMobile Tablet Plan: Magic & TTL
3. $20 AT&T Tablet Plan: Magic only
4. $25 Visible Plan: Magic & TTL

By Performance (Upload:Download):

Ok, Verizon was able to fix the way the data usage was displaying on my account. Now I can clearly see the breakdown:

Data Usage: 23.4GB (sim in LBR20)
4G Hotspot Usage: 1.8GB (sim in iPad)

So, for my Verizon Postpaid Tablet Plan, it appears that TTL of either 64 or 65 will mask the hotspot usage ...

Unfortunately, the Verizon portal doesn’t differentiate mobile data vs hotspot data for this tablet plan, so it’s difficult to know exactly what’s being used.

Activated the sim in an iPad LTE and then migrated to the LBR20 with magic, so only shows 2.3GB usage on the data usage page since ...

Voila! Once I fixed the script, I regained SSH access. Crazy how that script would cause the issue.

Just updated to the newer v9.2.5.2.23.1 Voxel firmware and it seems to be running well. Will continue comparing speed and performance results via WiFi as I’ve already established a baseline.

Up and ...

Yes, I downgraded from v2.6.5.2 to v2.5.2.20, then did a factory reset and then installed Voxel’s build.

Ok, thanks for the help. Will update the script accordingly!

So does the netwall.conf file also need to be executable? That might help explain why the ports aren’t staying open on my specific install.

I would much prefer to avoid doing another downgrade/factory reset. Will see if the updated ...

Maybe it’s my firewall-start.sh script that’s creating the SSH issue. Let me know if you see anything in my script:

#!/bin/sh

while [ 1 ]
do

# IPv4 TTL mod
iptables -t mangle -C POSTROUTING -o wwan0 -j TTL --ttl-set 64 > /dev/null 2>&1 || \
iptables -t mangle -I POSTROUTING 1 -o wwan0 -j TTL ...

Did a fresh install of the Voxel build this morning.

LBR20 with Visible sim is now up and running. It appears that once you add the firewall-start.sh script, you lose the SSH capability. Still have port 22 open in netwall.conf. At least in this version Telnet is still available via debug page ...

Here are my initial notes on the Voxel firmware:

1. SSH/Telnet banner says LBK20 instead of LBR20. Easy Cosmetic Fix.

2. After initial SSH access, and creating folders to add the ‘firewall-start.sh’ script, I lost both SSH and Telnet access. Tried rebooting and still no access. I suspect some ...

This comparison was to compare which carrier’s plan is more suited to my needs, that’s why I merely wanted to test them side by side on the same (newest) firmware v2.6.5.2 vs the older v2.5.20. I’ve seen improved speeds on both carriers when running the newest firmware vs the older builds. Here’s ...

Great News! Will try it out before the end of this week and provide feedback.

The latest firmware v2.6.5.2 has been very stable and showing faster speedtest results. Currently have two units running to compare; one with Visible and the other with the AT&T Tablet Plan.

As expected, the AT&T unit ...

*** UPDATE ***
It’s safe to update to v2.6.5.2! CircleJerk still present and all is working as expected. No need to reinstall CJ. Performed about 4 reboots……and all is well.
***************

Anyone tested the new firmware 2.6.5.2? Does circlejerk still work with no issues?

May test it this weekend.

Was able to request the EG18 modem AT Commands Manual from Quectel and put together the following Telnet commands that work with the LBR20:

Enable Auto Band Setting:
echo -ne "AT+QCFG=\"nwscanmode\",0,1\r\n" | microcom -X -t 1000 /dev/ttyUSB2

Enable Default Band Setting:
echo -ne "AT+QCFG ...

Need some help! Trying to lock Band 66, with Band 2 as the backup. This is what I tried:

echo -ne "AT+QCFG=\“band\”,0,20000000000000002a\r\n" | microcom -X -t 1000 /dev/ttyUSB2

Also, what’s the command for removing the band lock and putting it back to Auto?

Finally was able to find the LTE downgrade file to go from A06 back to A05.

Hope this helps if anyone needs to downgrade.

Login via SSH as root, not admin!

Think you’re right about the MBN mismatch with the Visible sim since the feature to select a preferred MBN only exists in the newer firmware.

The password issue is no big deal, just that I wanted to ssh into the device on the fly from my iPhone to make any script or ttl adjustments. Luckily, I ...

Comparison shows the new firmware 2.6.3.50(A06) with circle_jerk has slightly faster and more consistent speeds. Also the unit seems more reliable overall.

Day 3 and it’s been online 100% vs the other unit with older firmware 2.5.3.4(A06) which I had to reboot at least twice due to it randomly ...

Updated my Dev LBR20 unit today with v2.6.3.50 and A06 LTE firmware.

Did the manual circle_jerk install and all is working as expected. Visible sim and TTL of 64. Compared speeds on this Dev unit with my other Main unit running v2.5.3.4 and A06 (with old armor scripts, no cronjobs), and the speeds ...

Before I run the auto deploy on the circle_jerk, can you advise what exactly the scripts are enabling/disabling?

All I want is the speed cap removed (Visible) and the firmware auto update disabled. Does the auto script also disable wifi? If so then I won’t run in auto mode.

What do you think was causing the cronjobs to be deleted?

I was running A05 for weeks with no issue, then the problem started the day I updated to A06. Didn’t update the firmware, just the LTE.

I would like to dig deeper into this.......so if a method is discovered which allows one to downgrade to ...

Agreed, the A05 LTE firmware was the most stable before I upgraded to A06.

On A06, the speeds would randomly drop to 5mbps/5mbps overnight requiring a reboot to get back to faster speeds.

Followed hazarjast’s recommendation and deleted the cronjob method and moved to the simple script with ...

Played around with setting the sleep value at 120 and then 60. Appears that “sleep 60” seems to work best as it executes the script every minute, so once all the services are loaded....it fires up the ttl_mod much faster (approx 2-3 into the reboot).

I’m waiting on my second LBR20 to arrive this ...

With the revised basic ttl_mod script, I’m now getting uncapped speeds of 60/30. Upon each reboot, speeds are initially 5/5, but after about 10 minutes they are back to the higher speeds.

It appears the script isn’t running until 10 minutes after each reboot. I can live with it, but is there’s a ...

Ok, will try the updated script. Just to be clear, if I don’t need to turn off WiFi and don’t need the 60 second wait, can you let me know the bootstrap script format?

Is it just:

#!/bin/sh

/mnt/ntgr/armor/mods/ttl_mod &

Thanks again!

I’m using Visible in my LBR20. So, yesterday I did a factory reset 2.5.3.4, updated to A06 LTE and recreated all the scripts using telnet and old method. The unit appears to work fine during the day, but each morning, the speeds are back to the capped 5mbps/5mbps. It’s as if the scripts are somehow ...

Anyone have the A05 LTE firmware. Upgraded to A06 yesterday and it’s been very unstable. The connection seems to hang and I have to reboot to get reconnected every time it hangs.

Didn’t have this issue on the A05.

Cheers!

* I’m still on 2.5.3.4 and the TTL scripts are working fine with old method ...

Got everything working on the 2.5.3.4 version. After doing the TTL mod via telnet, I’m consistently getting 60/30 with Visible sim and the scripts are surviving reboots. Much thanks hazerjast for this tutorial. LBR20 seems like the best tri-band lte router once you get the TTL mod working. Let me ...
