Male To 2 Female RJ45 Splitter Ethernet 2-in-1 Internet Adapter Cable Separator

It simply does not and can't work with two connections at the same time. It should say so in the description. It only works if just one connection is used, which is useless for my purposes. As soon as you connect another device via the second connection, both connections will stop working. Very disappointed 😞. I will ask for a refund. Updated: I increased the rating to 2 stars just because I got a refund. This product simply cannot physically work as described, and here's why: https://youtu.be/QgrVVyIzecM?si=r71JDrP9N9IBVLmm

For the price is doing its job. But I think in description should be added that if both 2 ports are connected simultaneously, you will receive a speed of ~ 10MB Upload and 10 MB Download. If I leave just one port of 2 connected I get the original speed, like ~100 MB Upload and ~100MB Download. I have attached screenshots to show somehow a proof.

So plugged two devices into this and fort it would share access but unfortunately which ether one is turned on first dominates pretty useless

A really nice packaged item. Let's hope it works as good as it looks.
