My internet speed is 1.5 gigabits per second, but my desktop only has a port that handles 1 gigabit per second. Should I buy a USB-to-ethernet adapter that goes up to 2.5 gigabits per second, or should I get a PCIE card instead? If the adapters work fine, which brand would you suggest?

my computer has a 1gbps ethernet port. I would need your make and model of the motherboard so we have more details. Also, please tell me the make and model of your computer case, because that helps us avoid problems with space if you want to add something new (like a card). Regarding what to buy, can you say where you are in the world and how much money you plan to spend on an adapter?

So I guess your router has a 2.5 Gbps LAN port and you're going to plug in a cable right to it? If you can put an internal PCIe card, that should be easier for good results. USB is all over the place because there are so many different types and some ports go at different speeds. You'll need USB 3G at least but instead of figuring out which port is fast or slow I just would use a built-in card. Don't worry if you find almost no information online that runs that speed. Maybe try the speedtest site but most other places either can't do it or have fake limits to stop people from hitting them with too many users and super-fast connections.

I have a modem with a fast 10 gigabyte per second port, so I run an ethernet wire straight to my computer. Does the type of connection matter? Is a wireless dongle or a wired PCI-E card faster than just using the built-in port on the PC itself?

It's probably safe to say this port can handle 2.5, 5, or 10 gigabytes per second. However, some ports only support up to 10 Gbps. You should use the right USB 3 connection for this. It gets really confusing because they change the names all the time, like calling it "3.1 gen 1" or "3.2 1x1" instead of just saying gigabit speed. PCIE slots are much easier to check if they will work or fit your device.

My setup uses a Bell Gigahub with Fibe 1.5 technology. What PCIE card do I need to buy? There are many choices, and they come in different versions depending on the chip used. The main options include rtl8125, rtl8125b, or an I225-V.

Most websites don't work at all. You don't know what computers or other things are behind them, and even if you find them, they have boring web pages with common questions instead of a manual where you can check their specs easily. I would call those people idiots and ask for help.

I think @ bill001g is right that some 10 Gb NICs won't work on 2.5 Gb networks, so watch out for that. The bigger issue to your question is about USB average speeds. If you use the right connector (something like USB3+) and don't share a root HUB with another device, you can get the speed you need. But this only works if you aren't sharing that internal HUB among other USB3 devices without realizing it. That said, a PCIe card is better for lower latency. If you go with PCIe completely, you skip the long USB path and get faster response times. Also, reliability will probably be higher on this setup.

I'll be using this adapter. I want to see if I can get 1.5 gigabits per second from this card and that Bell Gigahub modem. What makes them offer a 1.5 gigabit plan alongside the Gigahub?
