Hardwired internet ghosting?

I have an ethernet line plugged directly into my router. I get more ghosting (riders dropping in and out) when I am connected this way versus WiFi

Anyone have any suggestions to improve or reduce this ? Thanks for the consideration

You could have a bad cable, try replacing it with at least a CAT6.

Also what is the length?

Good suggestons, yes to your point it is about 50 feet & the ends are about 5 yrs old, I’ll try replacing them
