LB2120 Failover Time - How long should it take to switch?

[jeff98363]

My system is set up using LB2120 in Bridge mode between my cable modem and my router.  It's configured to switch to 4G backup if my cable modem is disrupted.  I conducted quite a few tests disconnecting the cable from the cable modem to see how long it takes the system to switch over to 4G backup. It's averaging 2 minutes 45 seconds (give or take 15 seconds).

Question 1:  Is that the performance to be expected? 

Question 2:  Are there configurations I can make to improve the time it takes?

I was hoping for it to be faster, like about a minute.  Thanks.  Jeff

Are you browsing the internet when you disconnect? When I do a test it takes about 30 seconds to a minute.

Yes I have the internet browser open during tests to check for internet connectivity.  At the same time I'm watching the power button indicator on the LB2120 which indicates when cellular connectivity begins.  I'm also watching the Netgear dashboard page.
