Network cable issues
Lengthy issue here but fairly unusual.
I have some xboxes, ps3s and pcs in a basement wired via cat 5e in wall (I didn't do the install, previous owner did) to an upstairs jack then to router/AP. All was well for a year, used to get gigabit connectivity to downstairs. Then one day my main router stops working (only the wired connections), wifi works fine. I decide without much diagnosis to replace it with an Asus RT-AC66U router. All is well, then few weeks later, that router starts cutting out (no internet connectivity). After some major trial and error I find the issue, the network cable from the basement is causing the outage, I unplug it and router is fine.
So I'm thinking it's the giga switch in the basement. Replace that with an asus switch. Negotiated speed drops to 100mbits but at least I have connectivity. Then after a few weeks, the router starts doing its death dance again.
Now I'm thinking it's clearly some sort of intermittent signal/cable issue that's knocking out the router. Problem is how can I diagnose this without wall disassembly preferably. I've recrimped/resocketed both ends of this in wall cable without much success.
