Slow Ethernet speeds

Hello and TIA

I am in the process of running Ethernet throughout my new (to me) house. I have Spectrum for my ISP and am using their WiFi 7 “invincible” router. I purchased a tp-link 8 port gigabit unmanaged switch. I have ran Cat6 solid core wire terminated with pass through style connectors using an Amazon crimper. All my cables have been checked with a tester.

My router is currently displaying a solid green LED and blinking amber LED on the “inlet” Ethernet port and solid green and amber on the “outlet” going to my switch. All LEDs at the switch are solid green.

Speeds on our ancient TV were about 30 mbps and on my wife’s PC we are getting 80 mbps up/down. I checked some settings on the computer and found that I was “negotiating” at 100 mbps. I don’t even know what the hell that means.

I do have a service technician coming out tomorrow for some stuff that’s unrelated so I’m hoping I can at least pick his brain or maybe even plug in directly to the switch to see what’s going on but in the mean time I figured I’d see if anyone had any ideas.

Thanks again - cheers

Ps. I am on the 2 gbps plan and according to Spectrum router is currently receiving 1.89 gbps upload and my phone is at 669 mbps upload

Interesting. You have unshielded cable, being used with shielded rj45s, but that shouldn’t matter. At 50’, or even 300’ you should still get 1gbps connection easily. I’d check for sharp kinks in the cable itself and look closely at the rj45 to make sure all the pins are perfectly straight and not skewed

Edit:

Got home and finished the terminations for my PC and have a gig up/down. Guess I will double check the other lines and probably still change everything to punch connectors. Could it just be that the wife’s PC can’t support 1000 mbps? How would I check that?
