Quincy Madunezim says:

I have a Late 2014 mac mini, core i5 2.6 that has Gigabit Ethernet(10/100/1000Base- T). What is the best ethernet cord to use to maximize the speed of my performance, cat 5e, cat 6, or cat 7. Which ethernet can support my mac mini and does the length of the ethernet cord matter?

aaron Snell says:

er, do some mobos have built in network interface shit now-a-days?

George Goddard says:

what CAT should I use for gaming?

amertino says:

Actually RJ45 is an old standard that does not use T568A or T568B nor standard 8P8C plugs.

I am not even sure why most people mention RJ45 when talking about CAT cables, which is even more incorrect that reefer the plugs as RJ45.

Infernial says:

I just moved my Xbox One so my router is literally on top of my Xbox. I’m using a CAT-5 cable, but plugging it into either the Ethernet or GigE ports leaves me with a download speed of 10Mb/s and 170ms lag. I’m good with technology but not very experienced with ethernet, what do I do?

Anirudh says:

I’ve 300Mbps connection

I Wesley says:

Jack Cooper says:

do you need a network adapter to get internet on a pc?

Barry is says:

whats better Flat or Round CAT 7 in the wall so stealth does not matter. I want fast fast!!!

Bernardo Rebolledo says:

so I want to connect my Ethernet cable to my PS4 but I want to know if my family can still use wifi while I’m gaming.

Jonne Backhaus says:

wait what. the links after the switches? They do not count, its the 100m per active segment, every jump from a switch to another or from ja ethernet device to the switch is counted as as single active segment. Naturally not counting hubs, but no-one uses those anymore

Julian Acosta says:

ok, this is by far the best video you guys made. I was actually looking for some information and got that and tons of laugh. Thanks!

Glenn Watkins says:

Please comment on the CAT6 Flat Ethernet cables sold on Amazon and eBay. Is a flat cable as good as a standard round ethernet cable ?

MrRandomman21 says:

hey I know little about ethernet cables and stuff so don’t be harsh but I moved into a house and next to my ps4 there is a out lit that says cat 5 but when I connect an ethernet cable to it and into my ps4 it obviously doesn’t do anything. how to I make it connect to my router/modem that is downstairs through that outlit??? someone please help

IntarwebUser says:

You’re so enthusiastic.

Lucian Andries says:

HELP PLEASE: I have a cat7 cable, that doesn’t support gigabyte speed…! WHY?!
When I plug it it, the network adapter sees it at only 100 Mbps. I tried all the ports in the router, still 100. Yes, the router is 1 Gigabyte. My first cable which is cat5e works at 1000 Gbps. So wtf? :(((
What can I do to make it work? Teach me please!
