Good morning,
I currently have a Netgear MR1100 LTE modem / router and a TP-Link A6 router. Plex works great on the home network but I’m fighting the Double Nat issue. I’ve been through the guide to correct Double Nat and have been unsuccessful. I’m curious if I replace the router with a switch and let the Netgear do all the work, will plex still work on my home network like it does now and maybe help the Double Nat issue?
Thanks,
Larry
If supported by the device, put the TP Link router in Bridge Mode. This disables the routing capability, effectively turning it into a switch + WiFi access point. All routing, addressing, etc will be handled by the Netgear.
If you are using the mobile network for Internet access you may run into other issues.
Many mobile carriers now use Carrier Grade NAT to handle IPv4 addressing. The three major US carriers, Verizon, AT&T, & T-Mobile, all use CG-NAT in their mobile networks (a Google search for “AT&T mobile CGNAT” etc provides many links to confirm) .
CG-NAT does not support port forwarding, so it prevents remote access for services such as Plex. You can still access Plex remotely via Plex Relay, but the service will be limited to 2 Mbps (1 Mpbs w/o a Plex Pass).
Your carrier would need to provide you with a publicly reachable static IP address that supports port forwarding, and not all provide this capability.
There are several threads on the forum regarding Plex and CG NAT. This one has a good discussion of the issue and possible resolutions: How to Setup Remote Access with CGNAT & Static IP Address .

That makes sense. Thanks for the explanation.
