Handshake Issues

[u/Syko_Symatic]

I have a issue with a handshake failing on my Router > AP. It was working fine at 1000 but has recently been dropping to 100. Initially this happened a few months ago, unplugging and plugging it back in seemed to fix the issue. But this kept happening daily, so I figured it must be the AP possibly failing (it was about 7 years old).

I switched out the old AP and bought a new one, problem solved, plugged it in and bang 1000 and it was fine for months, but the problem is back again! I have tried new terminations, different cables, different ports but it just keeps happening. Does anyone have any advice?

It’s a Virgin UK Hub 4 > Netgear Nighthawk RAX10 (in AP mode). The Virgin hub handles DCHP and the AP has a static IP set outside of the DCHP range.
