Insignia Cat-5/5e/6 RJ45 Inline Ethernet Cable Coupler Adapter - Grey - Only at Best Buy

Got the job done , allowed them (DirecTV) for first time in 10+ years to register/establish an internet connection to this specific DVR after losing home tel line to another office device 10 years ago. Able to connect home router to my DirecTV HD DVR using this handy coupler x 3, and allow easy browsing of their movie library, pick my favorite adventure/drama/war movies to watch. Needed 3 of these couplers to bridge the gap from TV area to router room in basement and the price for each coupler was reasonably priced. The electronics person was extremely helpful in finding this coupler and getting the needed footage of cat cabling to make all this happen.

Got a call for a customer having problems getting abysmal transfer speeds and experiencing file transfer errors etc. Upon troubleshooting I found what is perhaps the worst couplers produced. Actually I found they bought 8 of them off of which went promptly into the trash immediately resolving their issues! You can ignore the CAT 5 or CAT 5e Rating because they are NOT suitable for FastEthernet or GigabitEthernet... The product description is bogus.

Of note is that I bought this for a particular need - I have a desktop 4 port gigabit switch that I sometimes want to bypass with a direct connection. This allows me to easily do a temporary bypass, though at the cost of some speed (it's only rated for 10/100). So it's great for my use cases and a great price. I would not recommend it though if you want to leave it in place permanently joining two shorter cables, UNLESS you're absolutely ok with the slowdown. A single cat 5e or cat 6 line will be faster than two joined with this. That said, it's great at doing exactly what it says it will do and a great price, so hard to argue with that.

You just never know when you will need one, and when you do, everyone, especially you, is glad you had them. Couples two Ethernet cables together to give you their combined length. (Cables sold separately or you must have your own.) Connect devices that out of range of WiFi via an Ethernet cable or when visitors come and the kids need more speed online to enjoy faster multi player games. Just use them to click in the Cat 5 cables and off they go! Beyond clicking in the cables, no set up required, they are just a pass through of the signal in the cable literally making it child's play to use.

I had gotten this coupler in hopes of being able to couple two Insignia Cat6 Ethernet cables. Unfortunately, on my end, it did not work at all. I had the coupler connect a 14' Ethernet and an 8' Ethernet cable. I did notice that the rating for the Ethernet coupler was set for a Cat5/Cat5e. This could very well be my mistake, however, it was the only Ethernet coupler available and offered. The build of it was plastic, felt like if you hit it hard it would break easily. Would not recommend for anyone planning on joining two Cat6 Ethernet cables. The purpose on my end was to create a hard wire connection to the Xbox One S. Ended up returning the adapter and buying a 25' Cat6 Insignia Ethernet cable.
