I have a Netgear CM2000 modem, an RAXE500 Router, a TP-Link TL-SG105-M2 Multigig switch, and I'm using Xfinity with 1.2 gig internet. I am having trouble setting up my switch. I think something is going wrong, so I can't figure it out. Can someone walk me through how to wire things? When I buy the switch, you should wire the modem all the way to the switch, then from the switch all the way to the router. That's weird... when I plug a cat6 cable into my switch and connect it to my PC there is no connection. But if I take that same cable off and plug it directly between my switch and the router, I get internet. I am stumped... my router only has 1gb lan ports, but on my speed test the PC clocks at 982. When I run a speed test through the router it shows 1249. I only have one 2.5 port on the modem and one 2.5 port on the router, so the switch must have four more 2.5 ports available.

If you wanted one PC to go faster than gigabit speeds, you should have bought a router with several ports that can handle 2.5Gbps+ traffic. A simple router with just gigabit ports won't be able to keep up when you connect many devices at once, including your Wi-Fi. You only pay the internet company for one IP address, but the router is what splits that single connection so everything on your network gets it. Putting a switch before the router usually works fine, if you just turn on one device at a time from the switch. However, if you plugged your PC into the switch while leaving the router plugged in, things wouldn't work as expected. Think about this: the modem only gives out one IP address and already gave it to the router. So for everything to work like you wanted, unplug the router and anything else that's connected to the switch when you're using your PC. Alternatively, just buy a real multi-gigabit router instead.

The router only has one port, and all its LAN ports are 1 gigabit. So, without a switch, you're using two wires: one for the modem to the router. The thing I want to know is how can I add more of those 2.5 gigabit ports with the switch and still get fast speeds?

You can't fix that with a normal switch; you actually need to buy a completely different router. The main reason? You have to make sure the "WAN" port can handle 2.5 gigabytes per second, and at least one "LAN" port must do the same. Even if there is an extra 2.5g port, that's not why it costs so much. It's mostly about having a big processor inside the router fast enough to move all that traffic between your internet and your computer. There are some routers with multiple 2.5g ports, but they usually cost more money upfront. Before you spend a lot of cash on this, ask yourself: why do I really need faster than 1 gigabit for my internet? It won't make Netflix or web surfing feel any different. It will just let you download files slightly quicker. How much is it worth saving just those few minutes every single month?

Your router only has ONE 2.5Gbe port. This means your setup won't work as planned. You need to buy a router that has two ports and use your current Netgear router just as an access point instead. The path should be: Modem --> Router --> Switch --> Access Point. Dong Knows has some links on routers with dual 2.5Gbe ports, but personally, those are all ARM processor routers which are a little too slow for my needs. If you play games and have several people in your house, I'd recommend getting one of these Intel Celeron X86 routers that sell on Amazon or other places. They cost less than $200 and will be able to use Fast Quality Code or CAKE algorithms at your full internet speed. Something like this: https://www.amazon.com/Qotom-Firewall-Ce...B09ZY26BPZ Load it with OpenWRT or Pfsense, whatever you want.
