If this is the wrong area then please let me know so I can change it.
I just bought a new Netgear AX3000 Nighthawk router for my home, I have installed it ok and it’s running much faster internet than with my previous old router on all devices however now my plex videos seem to buffer after 2-5 mins on everything that I watch in my plex library and I have tried a heap of different things in my library. I did not have this issue on my old tp-link router. My pc where I run my plex server is connected via ethernet directly to the router as with my TV. There is no transcoding happening as my connection is fast enough to run all my various video qualities so it’s not a transcoding issue. My Plex app is running on my Hisense tv with Plex for Vidaa.
I feel it’s some sort of setting in my router that I may have to change but I’m not sure what that would be.
I hope someone is able to help me.
a different local network, which means any IP and IP range-related settings in Plex server need to be adjusted.
Windows has classified its network connection as “public”, though you want it to be “private”.
If you used a manually created port forwarding, you need to re-create this in the settings of the new router. If you don’t remember the public port number you used previously, you will need to change this in Plex’s configuration accordingly. https://support.plex.tv/articles/200289506-remote-access/
DNS server settings are back to their defaults (which usually means DNS servers operated by the ISP). You might want to use alternatives, like 8.8.8.8 or 9.9.9.9
DNS rebinding protection might be active on the new router. If you’re lucky, the new router allows you to define an exception from this for the domain plex.direct. Poorer implementations only allow for a global ON/OFF. And the worst don’t allow any configuration. https://support.plex.tv/articles/206225077-how-to-use-secure-server-connections/
other detail settings like “NAT reflection” might need adjustment, too.
Most important of all, though, is to reboot all devices on your local network after the router has been exchanged. This is to ensure that none of them is trying to use cached information which was only correct for the old router and its configuration.
