XR500 Lan Ports Issue

I have suddenly got an issue with the LAN ports on my xr500.

They were intermittent, while back now, but in last couple of days it seems they don't seem to be recognizing anything at all.

I have connected to my LAN;

PS4

SKY

SONOS Playbar

Switch

TP-Link

every one of the above worked perfectly until a couple of days ago.

I have done a complete factory reset on the xr500, after first trying the power off leave for a while and turn on, which I did for all devices connected via ethernet.

I then changed out ethernet cables, had spares, and again to no avail.

WiFi works effortlessly, except for the Sky Q box, but personally think thas a sky issue as everything else connects and works no problem.

I really want my ethernet ports back, especially for my PS4 and gaming, the whole reason for buying this router.

Don't know if it means anything, but the lights on the front still light up as and when devices are apparently connected, i.e. PS4 is connected port 1, and when its off light is orange, when I turn PS4 on light goes white, but when I try to setup network using LAN it doesn't happen, same for everything else connected.

I see that some have had a PM with a firmware update, so praying that's going to be a fix for me too.

Heres hoping someone can help.
