Inconsistency with connecting to my Jellyfin server from local network

[NightFury]

I have recently updated my spectrum router to take advantage of the wifi 6e. Since then, I have been having issues connecting devices in my local network to the Jellyfin server hosted on my Windows 11 machine (Jellyfin Media Player works on this machine). I can sometimes connect from my TV and mobile phone in my local network but sometimes the server cannot be discovered. What might be the issue?

Verify that it isn't putting your devices on separate subnets. Make sure that AP Isolation isn't enabled.

I don't have an option to disable it as Spectrum doesn't allow me to change the router settings. Is there any other workaround?

Are you able to see any info about what the router is doing? Do you clients on the 6E network get different IP addresses?
