Home phone no longer working after installing mesh network
We installed a Netgear Mesh Wifi System today, with ATT Fiber internet and voice in the house. In other parts of these forums, I found instructions on how to put the ATT router on IP Passthrough, etc: https://forums.att.com/conversations/att-fiber-equipment/set-up-netgear-router-with-att-fiber/5e5be2aee0718126f46b688d.
Well, I got the mesh network seemingly working just fine, but now the house phones aren't working. The ATT router has a green light for phone, I log into said router and it says everything is fine with the voice line, but the house phones have no dial tone and they say 'check phone line'. I didn't change anything whatsoever about the phones, just the internet, so why are the phones seemingly completely disconnected now? Help.
