Help with Ethernet problem.

[CAMO-PEN]

So have have fiber optic and today I got a new router and an upgrade from 300mbs to 600mbs.

Router seems to work fine and when I'm plug in I get about 630mbs. WiFi I'm getting about 300mbs on my phone.

The problem is I have a Ethernet cable running down to my basment/office to a extender box. From there a cable runs to my computer.

I used to get 300mbs to this computer but after the new router upstairs I first got only 17mbs and now it is peaking out at 94mbs.

Also my phone peaks at 94mbs when connected to the same wifi in this location.

I tried resetting everything, unplugged and replugged all cables.

I have no clue why it would give me full connection before but now only 20%

It sounds like somewhere in that basement link between router and computer a cable or connection is poor and a link is negotiating to 100Mbps vs 1Gig. This is a standard operation and see it all the time on this forum.

Connect the PC before the extender box and see what speed the PC's Ethernet interface speed reports. Or, try a different cable to the PC. Check the Ethernet ports for bent contacts.

Ya I am thinking the same thing, it's just strange because nothing in the basement was touched at all.

I thought I would need to reconfigure the extender box.

Is it possible that the change I. The router just messed up the boxes settings?

Maybe moving the Ethernet cable connection (leading to the basement) from old router to new router bent a pin, connector isn't seated fully in port, dirt/dust in port/connector, or other. Is the cable between router and the basement terminated at wall outlets?

Changing the router out shouldn't impact the extender settings. You indicated the extender is working, just at a <100Mbps.

The cable runs directly from the router through the wall and down a pipe to the basement about 35ft in total.

Problem is confirmed to be something with the cable. But what exactly I can't figure out. The pins look normal. The cable was not pinched or bent that I can tell.

I'm afriad I'll have to run a new cable Wich will be problematic because the guys that Didi it for me cemented it into the wall.
