Issues with using male to female adapters for ethernet cables?

[southwestform]

I need to extend the length of some ethernet cables coming out of a wall. My first thought is to simply get male to female adapters on the ends of each ethernet cable coming from the wall so I could then simply add another ethernet cable on the ends to extend the lengths.

Does going this route (using these male to female adapters) slow speed down at all?

Thanks.

There is a slight penalty, but not noticeable.

Those connectors don't always work, you can either buy one and try it or simply get a longer cable online. Getting a cable from a store is usually a bad idea as they mark those type of things up a lot.

barrel connectors! i've used plenty of them in the past and you'll be fine. just make sure to purchase straight through connectors and not cross over connectors. they won't slow down your speed. ethernet, of course, is built upon using twisted pair, and barrel connectors don't provide twisted pair. so you don't get the shielding that twisted pair provides. the only way your speed would slow down would be if ethernet frames become corrupted on the line and get dropped when the receiving device performs the CRC check on the frame and finds that it doesn't match. and the speed slowdown doesn't mean your interface slows down it's transmission speed. the slowdown means the frame has to be resent, and that takes more time. that's where slowdown occurs. as long as you don't get dropped frames, your speed is still the same. you can always connect your barrel connector and then check for CRC errors on your interfaces.

^ Yeah it's called a coupler, which I will admit is better than a connector.

So should I be looking for a "barrel connector" or "coupler" or are these both just the same thing?

Thanks!

Same thing. A name is just a name. Print out the picture in the link I posted and take it in to your nearest computer store.

Some of the couplers, like this one, http://www.amazon.com/Your-Cable-Store-Ethernet-Networking/dp/B001SIS8YI/ref=sr_1_1?ie=UTF8&qid=1403506151&sr=8-1&keywords=coupler+cat6 are labeled as intended for cat6. I have no idea what the cable coming out of the wall is, though the cable that it will be connecting to will be either cat5 or cat6. Are these couplers universal with all ethernet? OR do I need to buy one that will match the speed of the cable?

Thanks.

Buy whatever is cheapest. Cat5e and cat6 both pass 1g. The speed is controlled by the equipment not the cable or the couplers. Pretty much the only impact the couplers have on the cable is the increase the resistance a little. You would only be concerned if you were trying to run at maximum distance of 100m. Even then there is a little extra in the standard so it will have no impact.

I would not buy from this company purely out of principle. "3-5 times faster than standard cat6" is a huge outright lie. Cable is certified to meet certain standards and only those standards matter. But lets say it can run 5x faster so now you get 5g. There is no such thing as a 5g port so what good does it do you. The ports in equipment go 1g or 10g. The standard for 10g is cat6a or cat7 cable.
