Tp- R605 with dual WANs. When I move my modem to WAN2 (backup) I lose internet
I have the R605 which has the capability of dual WANs. I am getting my second internet installed this week so, I wanted to test it. I moved my connection from WAN1 to WAN2 but I completely lost the internet. I moved the modem connection back to WAN1 and it works. I have the first and second WAN/LANs set up as a WANs.
My question is:
Why won't the R605 work from either WAN1 or WAN2? Why does it only work on WAN1? Do you have to have two internet connections before the load balancing works? Will WAN2 work if WAN1 fails to connect to the internet?
Do I have a setup problem? I believe that I have everythinng setup correctly, but if I don't, what is the correct way to set this router up with two WANs?
Thanks for your help!
