Having Trouble With PS5 Connection on Deco BE85 Mesh Router

I've been having frustrating issues with keeping a stable internet connection on my PS5 that is wired directly to my TP-Link Deco BE85 mesh router system. I keep getting the NW-102265-6 error code which indicates a network connectivity problem.

I've tried a few things to troubleshoot and fix this:

• Port Forwarding - I followed tutorials to set up port forwarding on the Deco BE85 for the necessary PS5 ports. Unfortunately, this did not resolve the connection drops.
• Wired vs Wireless - My PS5 is connected via ethernet cable directly to one of the Deco router nodes. I tried connecting wirelessly as well and still experienced connection issues and error codes.
• Router Restarts - I've tried restarting both the PS5 and rebooting the Deco router multiple times. The connection seems to work for a while but then ends up dropping out again after a period of time.
•  

It's frustrating because my other wireless devices in the house don't seem to have this problem, it's only the PS5 that is having constant connection headaches. I'm not sure if it's a configuration issue with the Deco BE85 mesh system or if there is some incompatibility with the PS5.

If anyone has experienced this issue and found a solution I would love to hear! My mesh router system is up to date on the latest firmware. And I've tried tweaking every setting I can think of without luck. Let me know if you have any advice for keeping a wired PS5 connected reliably!
