Having Trouble With PS5 Connection on Deco BE25 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 BE25 mesh router system. I keep getting the NW-102265-6 error code which indicates a network connectivity problem.

I've tried everything found to troubleshoot and fix this:

• 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.
• Changed DNS for the Google ones (8.8.8.8 and 8.8.4.4)
• Changed MTU: In Advanced Settings, change the MTU setting from Automatic to Manual and set it to 1473Change MTU: In Advanced Settings, change the MTU setting from Automatic to Manual and set it to 1473
• Changed mesh from access point to router and vice versa
• Changed Frequency Bands: Switch from 5 GHz to 2.4 GHz (and vice versa) in network settings. 
• Reset PS5 setting.

It’s really frustrating because none of my other wireless devices at home have this issue—only the PS5 keeps running into constant connection problems. I’m not sure whether it’s a configuration problem with the Deco BE25 mesh system or some kind of incompatibility with the PS5.

If someone has run into this problem and managed to fix it, I’d really appreciate hearing about it. My mesh router is already updated to the latest firmware, and I’ve tried adjusting every setting I can think of with no success. Any tips on how to keep a wired PS5 connection stable would be greatly appreciated!
