Review: Didn't work Updated worked - So, had these sitting around and never tested. Finally got around to it and no joy. Hooked one end to the Internet router phone port (that works) then to RJ 45 to the other end of the house. Then into phone. No dial tone. Tried two different phones Ended up being a problem with the cat 6 cable. It only had four conductors! Who does that???
Review: good stuff just was not what i needed - did not work for me in attempt to increase my modem line to higher capacity

did not work for me in attempt to increase my modem line to higher capacity

### ⭐⭐⭐ Didn’t work for my purposes
*by C***S on March 20, 2024*

I really cannot say much about this other than I had to return because they didn’t work for what I wanted. I needed an adapter that would make a small cord that plugs into the back of a phone and make it into the larger size jack plug. I wasn’t sure if this would work but gave it a shot and it did not.
