Hi all,

Looking to improve my home gigabit internet setup. Right now, I have my Netgear CM1000 DOCSIS 3.1 modem running into the Netgear Nighthawk AX1800 Mesh WiFi router. From the router I go into a TP-LINK TL-SG1005D ethernet switch. From the switch, it goes into my desktop, my roommates desktop, his Nintendo Switch, and the Philips Hue Hub. All cabling is Cat 5e. When I do a speedtest on my desktop, I only get about 90 Mbps. I am wondering what part(s) of my internet chain are causing the slowdown? Is the cabling on the front end not robust enought to transport multiple gigabit connections? Is is the switch that's the problem? Looking for any help I can get. Links for hardware provided below.

Router: https://www.bestbuy.com/site/netgea...6-system-2-pack-black/6392517.p?skuId=6392517
Ethernet Switch: https://www.microcenter.com/product/361816/tp-link-tl-sg1005d-5-port-gigabit-desktop-switch

Thanks in advance!

First I assume you have more than 90mbps internet connection ?

Speedtest is not really a good indicator of lan performance. It will only go as fast as your internet connection. There are other ways to test lan performance.

But 90mbps is one of those numbers you see when you have a bad ethernet cable. You have 3 in the path between you and the internet. You should be able to narrow it down by running speedtest on other devices and see if there is anything in common.

You might be able to tell by the lights. Your PC in the status display for the ethernet will tell you if are connecting to the switch at 1gbit.

Some cable is running at 100mbps. Generally this is a defective cable but it can also be fake cables. Cables...

Thanks for the response. We gigabit internet at the apartment so we should be getting higher than 90 down.
 
Almost certainly a bad cable.

Is your roommate's pc connection fast or slow? fast = bad cable to your desktop. slow = bad cable between modem and router or router and switch.

You can usually isolate the bad link with a few swaps - try plugging your pc into the router directly and the modem directly, etc.

Don't forget that there may be multiple bad cables - that always makes for tons of fun!
