Never used the orbi app, but Netgear tells me that it will notify me of updated fw availability. SOO, I just installed the Android version and lo and behold, it is gave me an option to update to fw version 2.6.4.2; which is NOT available on the Netgear LBR20 download site... Since, I've little to lose, I upgraded. As expected, lbr worked fine after upgrade and survived 2 reboots.

I then tried the circle_jerk automated install script which failed with message "...No connection could be made because the target machine actively refused it at 192.168.1.1:23" However, manual install worked. I was able to enable circle, ssh in and make minimal necessary changes to call_once and fw_rules scripts. Speedtest.net showed excellent unthrottled speeds on Visible. I then rebooted and once again the LBR failed to connect. Statistics is showing "link Down" for WAN, LAN and LTE. Connection status shows 0.0.0.0 both for IP address and DNS Server; while SIM is READY and SIM IMSI is shown correctly. In addition, Band Number is shown as '2' which is a Visible/vzw band available here. But Connection Status is 'disconnected'

Update: Netgear is processing an RMA to replace my unit.
I have had the exact same issue on Visible with 2.5.2.20 and FW A05. I am not sure what causes this to happen. I switched my LBR20s so the one refusing to connect to Visible connected to ATT without issues. The other LBR20 had been on ATT for months connected with the Visible sim with no issue. I just had to update the configurations a bit (just the APNs).
I haven't yet tried to switch back. I am wondering if something in the Visible SIM config is causing the issue.

What is the best way to factory reset the modem of the LBR20? Is the AT&F command the best way to restore the modem to factory defaults and delete carrier network configurations? I have not tried sending the modem this command to see if this might fix the issue, then re-insert the SIM as things are working now, but I suspect the same issue will eventually happen to all my LBR20s with Visible.

Hello,
Skimmed thru this whole post. Wanting to know if you can use a AT&T post pay tablet plan with little effort? Been using it in a Netgear LB1120 with AT&T post pay tablet plan with no issues. Just this is an out of date device Category 4 modem with no band 66. Just looking to upgrade but want to keep it simple. Like change the APN and ready to go simple.

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.

How is everyone using custom DNS when Circle is enabled?

With Circle enabled the custom/static DNS option cannot be selected in the UI? With Circle disabled I can set custom DNS, but then it reverts back to dynamic when I re-enable Circle.

That works :)

Sounds good, I will be upgrading my stable unit to the newer firmware this weekend to use 'circle_jerk' as Voxel appears to have now accepted my offer to ship my 'dev' unit to him so that he can release his firmware for the LBR20. Hopefully one day soon this will mean we no longer have to bootstrap off of anything but can run the device in any way we wish without dancing around Netgear's code.

No problem!
Fingers crossed that Voxel is able to release his firmware for the LBR20 8-)

This custom DNS server example uses Google public DNS servers
In the /mnt/circle/mods directory, create a new resolv.conf file, that contains the IP addresses of your desired DNS servers
vi resolv.conf
Hit ‘a’ to append and paste in the following lines:

nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 2001:4860:4860::8888 # IPV6 wwan0
nameserver 2001:4860:4860::8844 # IPV6 wwan0

Write & Quit
Esc
:wq
Edit the ‘call_recurring’ script
vi call_recurring
Using arrow buttons, navigate to the end of the last line of the script, hit a to append from that location, hit enter twice to leave a blank line and start a new line then paste in the following

# This command periodically overwrites stock DNS servers with the ones you
# saved in the new resolv.conf file
cp /mnt/circle/mods/resolv.conf /tmp/resolv.conf

Write & Quit
esc
:wq

Reboot; give it a couple minutes after the LBR20’s WiFi link comes up and load up 192.168.1.1/adv_index.htm, you should see the Google IPv4 DNS servers, or the ones you choose to use under INTERNET PORT

I have been using my Orbi LBR20 on AT&T successfully now all winter following the original instructions with the ttl mod script and shutting down wifi and blocking updates.

I am on 2.5.2.20 and FW A05.

For some reason my MAGIC keeps reverting back and it I lose internet connection. Reboot, redo magic and I am back in business. Less than 24hrs later it happens again.

IS this a known issues now? Do I need to upgrade and try to figure out this new process listed above to make my Orbi stable with AT&T.

Bump...Is this a known issue?? Do I need to upgrade and figure out the circle_jerk hack? Perhaps my firmware got corrupted? I did have a power outage.

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

https://www.downloads.netgear.com/files ... ge(US).zip

Hope this helps if anyone needs to downgrade.

What magic is getting lost? Did this unit every get upgraded beyond 2.5.2.20, this seems to affect persistence of settings and I would go forward and try hazarjast's solution for the newest updates. If not I would upgrade the LTE firmware to A06 as this did help some settings for me that seems to be spontaneously resetting.
