Have installed the Deco X95 to replace a damaged Archer AX90. The wired devices were working fine with the AX90 through the switch, however through the Deco X95, whilst they show as connected and obtain an IP, they fail to have any internet connectivity..

I swapped out the switch with a spare consumer grade 8 port DLink device and the 7 connected devices all connect, get IP's and have perfect internet connectivity, so it isnt the device or the cabling, it has to be an issue between the Switch and the Deco router.

What is puzzling is the same switch was working fine with the Archer AX90...

(Side note, i have an open case with TP Link, but the business support is only M-F for the switch)

Any ideas on what might be causing this issue???
