Ethernet

Random Question, Does the distance of an Ethernet connection Matter. EX: would someone have a faster internet speed if they were only 5 feet from the router rather than another room across the house? (30 feet of Ethernet cable)

Cat 5e and Cat6 are rated for 1 Gbps up to 100 Meters 

Cat 6a can do 10 Gbps up to 100 Meters. 

Cat6 can hit 10 Gbps on short distances.

As you work with longer and longer cables or cables not rated for a given speed it's not that it'll operate at a slower speed as it will run at the speed of the slowest interface.

 

Where cable distance will hurt you is in signal degradation, this results in packet loss. This causes packets to have to be resent (at least for TCP, general data loss will occur for UDP). This is where longer cables can cause "slower speeds".

No, even with cat5e cable, you get up to 2.5gbps, up to 100 meters, no packet loss, no issues.

 

Minor nitpick: there are cheaper CCA (copper clad aluminum, aluminum wires coated in copper) network cables which have higher internal resistance than proper ethernet  cables.

With very long lengths of such cable (let's say 30m or longer) together with network cards configured by default in "green" mode (send and receive using lower power than standard mode), it's possible to have some packet loss. Easily fixable by disabling "'green" mode on such cards.

You won't get any faster internet speeds from using shorter or longer cables. You would get faster transfer speeds if you're using 1Gbps rather than 100Mbps.

Im pretty sure the standard is not out yet. And if it is, I havent seen any equipment available.

2.5Gbps and 5Gbps (both fall under mGig iirc) are out and rolling out slowly on enterprise and a few prosumer products in certain places now.

Lots of x570 motherboards will have 2.5 gbps capable ethernet cards.

for example  X570 AORUS XTREME (rev. 1.0) has a 10gbps Aquantia card (which can also do 2.5g) and a second 1g card.

The  X570 AORUS MASTER (rev. 1.0)   has an intel 1gbps as primary and a 2.5g realtek as secondary

That's just looking at the first I could think of, Gigabyte.. MSI, Asrock, Asus.. at least one of them has more.

Cable length would add latency, but in such insignificant amounts you wouldn't have to worry. Other than RFI (Radio Frequency Interference) or EMI (Electro-Magnetic Interference) as long as you keep under the recommended length you will see no difference in performance.
