Weird issue with cable modem, speed, and connection
I have an Arris cable modem from Spectrum. It has 4 ethernet out ports. For many months i've been running two ethernet cables out from it, 1 directly to my PC 3 feet away, and one to the router for the rest of the house.
reason: if i go to the router, then out from that to my PC, i get about 65 Mbps. If I ran direct from the modem to my PC, I always speedtest at my full 120 Mbps. I gave up trying to figure out why my router was only yielding roughly half speed, and since a direct ethernet from modem worked, i left it at that.
This morning upon turning on the PC, i had no internet on my PC. I checked, and the rest of the house is fine. Now, no matter what, I can't get internet to the PC on the direct line from the modem. If I run a line from the router to the PC, it works, but still at ~50% speed
I have tried:
- all network reset commands (netsh winsock reset, etc)
- rebooting PC
- rebooting modem (twice)
- windows updates, incl drivers
- running network troubleshooter
- running ONLY direct line from modem to PC (pulled line from modem going to router)
- switched ethernet wires
- using 2nd ethernet in port on PC
by the way, months back, in trying to solve the 50% speed problem, I went out and bought a new router with all the latest standards, and to my amazement, still got 50% speed. So yeah, I have no idea what's going on.
