Wireless Joint

***9/15/20 UPDATE***
After some actual "production" testing (i.e. my wife and older son going through a couple weeks of at home learning) I'm finding that my chosen solution, Adam:ONE, was having some intermittent latency spikes as they don't have first tier anycast (routing DNS queries to the ...

October 2022 Update
I loathe boilerplate legalese but it was brought to my attention that someone had copied this tutorial wholesale on another site with only a passing reference to a pseudonym of mine at the very end and no link to this page as the source. Thus, I feel I have to give notice at ...

Any plan will work with the LBR20 assuming you configure it to be compatible. Read between the lines in my "Sending AT Commands to the Modem" section and check for spelling typos. That's all I will say here. Feel free to DM (hazarjast at proton mail dot com) if you need clarification.

...and whether you could set TTL to bypass hotspot detection on this propriety hardware with a locked down firmware...


Yes, it's running a customized version of OpenWRT Chaos Calmer with full iptables so mangling TTL is not difficult with the device. It is quick and easy to enable telnet access ...

@hazerjast, thank you for taking the time to document these tips. It is by far the best and most accurate information I have come across.

I have LBR20 router. I set it up with a SimpleMobile sim (T-Mobile). It worked great, immediately. I was setting this up for my Parents who have no internet ...

Updated the OP over the course of yesterday and today with router firmware v2.6.3.50 discovery information and an updated way to add reboot-persistent config leveraging the Circle functionality/filesystem.

Rookie mistake, the Windows Firewall re-enabled itself blocking TFTP. All is well now!


Fantastic! Glad to hear that is all it was. I had the same issue when creating/testing the script :)

I have gone back and updated the OP with troubleshooting suggestions based on the feedback I have received ...

Hi all, first time writing into this forum. I am thinking of getting an LBR20 because it looks like a great way to get a CAT 18 modem for the price. But I wanted to know what the circle_jerk script allows. I'm in fairly rural Washington and need to setup very directional MIMO antennas. The antenna ...

So with the updated ttl_mod script do we just make that script and comment out the TTL mod section of the script in fw_rules or do they both need to run? My Verizon tablet plan continues to use hotspot data and Circle keeps turning itself off so I'm trying to figure out what I'm doing wrong ...

What you describe is standard deprioritization. This will be worst during the most congested periods of the day. Try testing at 3AM vs. 8PM or at the very start of your next billing cycle vs. midway through a month. All other things being constant (band/tower/signal strength), this will confirm it.

ATT Post pay tablet plan will work with just APN change - but you risk termination as TOS requires SIM be used only in a tablet.


Pretty much anything done using the methods in this thread and forum are ToS violations to lesser or greater degrees (depending on which lawyer you ask on a given day ...

I found the price of the LBR20 quite competitive for the modem inside it of along with the basic functions it accomplishes (LAN Port, basic routing, etc.) Is there a much cheaper option I'm missing? Getting a CAT16 modem appears to run 225 by itself, and the LBR20 was only 300.


At those prices ...

Is there any chance someone can make a step by step guide on how to add the ttl mod for the V9.2.5.2.23SF-HW version ??????????????????????????? :? :? :? :? :? :? :? :? :? :? im just at a loss and i have done the circle mod but the ttl is not sticking so i could really really really use the help ...

Thank you hazerjast for your awesome work and info! I have my LBR20 running the newest Voxel. I'm running T-mobile Magent Max with working magic on the orbi and using the wifi from the orbi. Even with your great instructions I still can't get my TTL working correctly. Still having some leakage ...

Due to replies showing that the separate IPv6 script 'firewall6-start.sh' was not applying ip6tables rules I tested myself and found that indeed 'firewall6-start.sh' was not loading the IPv6 TTL rules on reboot/startup so I have updated my instructions below to reflect a single 'firewall-start.sh ...

Updated version of Voxel firmware is out (V9.2.5.2.25SF-HW):

https://voxel-firmware.com/Downloads/Voxel/Orbi-RBK50-Voxel-firmware/LBR20/LBR20-V9.2.5.2.25SF-HW.zip

I have updated the OP to reflect this as well. Release notes can be found here:

https://www.snbforums.com/threads/custom-firmware ...

In case anyone needed yet another reason to switch to Voxel and completely disable Circle, it looks like security researchers finally started exploiting ‘circled’ much as I did for my CJ implementation. Only difference being the remote attack vector of uploading malicious code into the unencrypted ...

Thought I would share something useful/fun that I thought I shared before but don't see it posted here so guess it slipped my mind. Netgear has a ~1400 line shell script which the LBR20 uses as a wrapper for some of the raw AT commands it issues to the modem. The script is 'mbctrl.sh' and can be ...

echo -ne "AT+QCAINFO?\r\n" | microcom -X -t 1000 /dev/ttyUSB2

...

I also have a few points on my own to all of you:

Somehow, the cell lock behaviour is quite strange in my case. When I lock it to one only, I partly still end up with CA enabled (as far as I can tell):

root@LBR20:~# echo -ne ...

There is no bridge mode, for all practical purposes, on the LBR20.


This is true. The real question becomes 'Why do you require a bridge?'. For most folks, the answer is usually "Because I need open NAT for gaming / running a server / torrenting.' In that case, bridging 'wwan0' from the modem to ...

Is there an error log somewhere after getting error sending AT commands?


Unfortunately, no; at least not easily accessible outside of the modem's internal logging. But, even if such a log existed that we could access from the LBR20 itself, it would likely not provide anything more verbose than ...

Voxel firmware V9.2.5.2.26SF has been released. Mostly package updates with some fixes as well. OP updated with download and release notes links.

Also, the successor to the LBR20 with WiFi 6 (though not the newer 6e standard) and 5G is now being sold by Netgear: https://www.netgear.com/home/wifi ...

I have noticed this in some setups especially VZW. Depending on the SKU of the unit and SIM ICCID the unit appears to struggle with the attach to VZW and then may be resetting itself with different MBN. Would be interested to know if your IMEI persists as long as you don’t reboot or if it is ...

Would not hurt to add '-w' (--wait) switch for anything using iptables based on the xtables-legacy* packages, IMHO.

FYI, I noticed at some point I broke the OP by accidentally truncating some of the earliest entries in one of my last few updates. Luckily I had a backup so I went back and restored the truncated info. The truncated info was all old stuff which is pretty deprecated by the newer updates but I figured ...

Thank you for clarifying this!

Several important updates have been made to the OP. Most notable: further simplification of the 'ttl_mod' script, a thorough fleshing-out of the 'bootstrap' method/script for clarity, and a change in execution method which now uses crontab for calling 'ttl_mod' (and any other scripts) at precise ...

Just as a heads up to anyone contacting me for LBR20 help: life is pretty busy at the moment so it may be awhile before I see and/or respond to your messages. Not trying to ignore anyone but have to keep my priorities in order. Thanks for understanding!

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 ...

Since folks keep installing my old circle_jerk mod on top of Voxel and gumming up the works I've removed all references to CJ in the OP. The relevant pieces of CJ info were moved to its github page for posterity.

Hi All,
While the LBR20 w/ Voxel firmware is still my daily driver, I have been working on a 5G build featuring the Quectel RM502Q-AE on a Raspberry Pi 4 for hardware using OpenWRT and ModemManager on the software side. Since github and markdown lent themselves a little better to hosting the build ...

Updated OP with link to latest Voxel firmware.

This may be the last update for awhile due to the current geopolitical events going on in Voxel's region of the world: https://www.snbforums.com/threads/voxel ... tus.77704/

Is there any additional detail on this post? I have an NBR750 I would love to try this firmware on. I attempted to upload the LBR20 but it won't take it.


Nothing additional yet. Voxel is only creating firmware for the LBR20 not for the NBR750. Not sure if/when NBR750 would receive aftermarket ...

Thanks. I think the only thing I really need is to lock out sprint bands as once in awhile it seems to REALLY want to do sprint only, even resetting, turning antennas etc. I get 7/.5 if I'm lucky on sprint.

Otherwise I'm getting 80/10, which is perfect for me, a big upgrade from the M1. B71 has ...

Well I seemed to answer a couple of my own questions while in a training about asset management, it was riveting!! :lol:

No problem, glad it can be helpful to you.

Yes, if you want to try the failsafe script just create it in the ‘scripts’ overlay folder (/mnt/circle/overlay/opt/scripts/), make it executable (chmod +x) and call the actual file (/opt/scripts/script_name) from rc.local to run on startup.

Circle_Jerk sits in a partition that doesn’t get wiped by a factory reset but factory reset does reset Circle settings which should keep it from running. Without SSH’ing in and manually removing the files and reverting to the factory files in the backup folder, you would probably have to flash ...

Introduction
Most likely you've purchased or are considering purchasing an Netgear NBR750/NBK752 (the latter being the bundle SKU with an additional satellite included), a.k.a. "Orbi 5G", as your primary or secondary source of Internet connectivity and found your way here through an Amazon review ...

Have you bricked your device? Did a firmware fail to upload and you had no choice to yank the plug? Is the light just sitting there blinking mocking you, EFF YOU, EFF YOU.

I did.

This saved my bacon.

Excellent guide and firmware, I was able to get it working very quickly.

Two questions...

Anyone attempt to update the firmware on the RM502 in this device? I didn't know if you could just get the latest and flash it manual via the GUI or if it would mess up what we have going on here.

Also wondering if anyone knows if the port labeled WAN/LAN can actually be used ...

I am hoping I can get some help. I have two Orbi devices. One is working fine with Voxel and needed no TTL mods as it is running a Mobile Beacon sim. The second is running Voxel and I cannot seem to get the TTL to stick. Carrier is Verizon phone postpaid unlimited plan and it is leaking hotspot ...

Thank you for the detailed post.
