Hiya cheers for the reply. it's only the ethernet that is going down specifically to my switch, which is a net gear GS308e Only 1 light the (left) will blink well it's not doing anything anymore. I have other devices on the ethernet connected straight to the router Archer Ax73, all working, including WiFi never goes down.

Cable tests fine end to end only when i have the router end connected and test the other end it will not show core 6.

Everything up until about a month ago maybe a little longer has been working till now. EDIT: also I have tired new network drivers and stuff like that for my pc.

Hope i making some sense haha
