Ethernet cable - Packet loss

[footballvideosofficial]

Hey guys.

I just built my pc and I firsy connected PC to the internet using a wifi adapter. I had P packet loss which was good but occasional lag spikes.

So I moved PC to another room, connected ethernet cable but I was getting packet loss (1-2%). Ping was absolutely stable though unlike wifi adapter, but this packet loss is unbearable. Cable is a bit old, so is it the cable itself causing this? Because I had no packet loss with the wifi adapter.

Should I purchase a new one or is that not the reason?

Get a really short ethernet cable and hook it up to the router directly. It could be the cable but its likely your ISP service.

Also determine if it's between you and router or between your router/modem and ISP.

The fact that it happens both on wired and wifi tends to point at ISP side. (or simply overworked cheap router/modem that cannot handle all the traffic, resetting it should clear the problem most of the time for few minutes)

Find out your routers internal IP (usually something like 192.168.x.x)
do "ping 192.168.x.x -t" in command prompt.
check for packet loss.
if it exists, it's inside your house.
If it doesn't exist do "ping www.google.com -t" for few minutes to ping outside google server.
check for packet loss.
If it exists, it's outside your house and your internet providers problem.

Most cables last 20+ years unless damaged, which is why we got 1GBase-T which works over cat5/5e instead of 1GBase-TX which requires cat6a for maximum reach: companies didn't want to re-wire their facilities to upgrade from the cat5/5e they put in ~10 years earlier for 100Base-TX. I wouldn't be surprised if something similar happened to 10GbE (trading technical complexity and wire-level protocol overhead for the ability to continue using cat5/5e) before it goes mainstream to give existing wiring another 10+ years lease on life before having to go optical.
