rv340w WAN1 loses internet but devices do not switch to WAN2 internet

[tonymiller60]

I am a sole proprietor and not a network specialist. I installed an RV340W to take advantage of dual WAN using two separate ISP's so if I lost one then the other would pick up my office internet traffic. But this has failed twice now. One ISP on WAN1 loses internet (the ISP stays active so my router doesn't see any connection drop, but there is no internet connection), but my computers do not automatically start getting internet from the other ISP on WAN2. I had to physically disconnect the wire to WAN1 and then my computers started getting internet from WAN2.  Is there some configuration that I need to do in my router to sense the loss of internet while not losing the ISP connection?

check the settings again one more time :

Also, you can ping 8.8.8.8 and fail over follow below thread :

Thanks!  I changed the NSD setting for both WAN connections to Detect Destination: Remote Host 8.8.8.8 (instead of Default Gateway).  Now I just have to wait for the next ISP failure, but I expect it should fail over as it should.
