Hey, i know they exist but i cannot find one, it is a little adapter that connects two ethernet cables together, i am in desperate need of one, i do not want a switch with multiple hubs, or another router ( i am currently using a router for an extender and it is only causing problems) So if anyone can tell me where i can get one, it would be greatly appreciated
Your question is kind of vague. If your line is over 300 feet, you need an ethernet extender like the one listed above. If it's less than 300 feet, you can use an ethernet coupler, but I recommend a continuous single ethernet cable over using a coupler.
The ethernet network connectors don't work too well, I have tried a few and none worked. Get a longer cable, they are not expensive if you get it online.
I agree, which is why I recommended a longer cable. Most couplers have loose fittings which can cause you to lose the connection even though the cables still look attached to the coupler properly. The ones I used worked, but I only used them until I could get a longer run in place.
