LBR20 - 4G/LTE as failover doesn't work flawlessly
Hi everyone, as suggested by a fellow user in the "Orbi" Forum, I repost my question here trying to get an well informed answer from the community. I've got an issue with my LBR20 configuration...
What I called the patch panel is a kind of "switch" for home dispatching of TV (DVB-T or DVB-S), TEL or Internet through RJ45 outlets. I far as I remember (I'm not at home), there are 3 IN ports (TV, TEL and NET) and 8 OUT ports; for each out port, you choose what type of signal the outlet behind the port is expected to receive (TV, TEL or NEt). I suspect that those litlle selectors are only for visual purpose, it doesn't really filter the signal or wathever. Anyway, I only use that patch panel to connect the plugged devices to the LAN (no TV or TEL signals injected)
Here is the model of that patch panel :
Here is the chain of connection :
- Cable Modem > LBR20 Router WAN Port (LAN 1) (Directly)
- LBR20 (LAN 2) > Small netgear Switch (Netgear) (Port 1: NAS, Port 2: Hue Bridge, Port 3: Patch Panel) > Satellite and other wired devices (Macs, TV, STB, AppleTV, etc).
Hi clemtys
The expected failure switch time is 2.5 mins.
To verify, is this how you setup Failover:
1. Please make sure that you have the latest firmware v2.5.2.20.
2. Enable WAN/LAN port as WAN port only
Go to Advanced TAB > LAN Setup > uncheck "Enable WAN/LAN1 port as LAN port" > click APPLY to save the changes.
3. Enable failover mode
Go to Advanced TAB > Setup > Internet Setup > Mobile Broadband Settings > Select "Use WAN Ethernet with mobile as back up in case of failure"
You will see the warning message "you have enable WAN/LAN1 PORT as LAN function when mobile mode, please disable it first". Click OK to continue.
4. Setup WAN
Go to Advanced TAB > Setup > Internet Setup > Internet Setup Page. Please input the WAN type and click Apply for setup

Hello Blanca_O ,
Thank you for your detailed answer and sorry for my late feedback. I finally managed to find the time to check the settings as you suggested and everything seemed properly configured.
You say that the expected switch time is 2.5 mins, which is good to know. Do you know if we can change this value and if not, do you know if it's planned to make it possible for a next firmware release?
And, my last question is : do you know how the router detects a connection failure? Does it ping a specific IP (if so, which one?) for example ?
I am testing the LBR20.. latest firmware v2.5.2.20
The time it switches from wires to Mobile from 2:15 - 3:15 minutes (need to do more testing). When i reconnect the wired internet connection, it is not switching over. The only way for it to switch is to power cycle the LBR20. This is not acceptable. if there is limited data server on the mobile internet connection, it could technically stay there for weeks if it's not monitored.
I'll continue tinkering with the for the rest of the week, otherwise, I will have to return this product.
Seconded on this question. A failover time of over 2 minutes is not useful, and the inability to revert to ISP connectivity automatically is even more disqualifying -- it would be far too easy to blow through an LTE bandwidth allocation without realizing it!
If it may help, after a few months with the LBR20, I can confirm that the switch to 4G when the main link fails can take up to 3 mns, I suspect I miss it sometimes but when you watch Netflix or similar, you can't miss it and this can be long, especially when the main link gets back up and down a few times in the evening.
However I have to say that I can't confirm that it doesn't switch back to the main link when it's up again. I can take some time (a few minutes) but it always switch back to the main link when available.
Dear Netgear team, it would be really useful to be able to manage the default detection time/frequency to be something closer to 30/45 secs.
