So the problem is with this antenna as I have no problems not using it. I have never had a problem with a Wi-Fi repeater that "converted" my Wi-Fi signal to cable for the PC. My problem is that I use a Steamlink box to stream games on my TV (my PC, box and TV are in the same room), and when the network is set to 80Mhz, everything crashes (the box, the steamlink, this network card). When I do a local data rate test, it's a real pain in the ass, and the data rates I get exceed my expectations. My Wi-Fi (Freebox) is set to 5Ghz with a bandwidth of 80Mhz, ("AC" Wi-Fi). I was a bit fooled, because I need my PC to kick ass on upload too.

Nevertheless it does the job, much more appreciable speed now. Another negative point, 250mbit/s is not 1000mbit/s either. A small negative point, the length of the wire for the mobile antenna could be extended by 50cm easily, it's a bit tight to put it where you want. I finally found the solution: the antennas connected to the card were probably not picking up the wifi, because on the mobile antenna provided, the connection is close to 250mbit/s and stable now. However, the speed with the wifi card did not exceed 50mbit/s with interruptions. I went from a real ADSL speed of 15Mbit/s to a theoretical fibre speed of 1000Mbit/s. I've been using it for a while now, but I'm not sure I'll ever be able to use it again. I've been using this card for a while now and it's a great product.

I almost gave it a bad mark, but in the end it didn't. I therefore opted for this card with very good reviews. Having changed my ADSL box for a fibre offer, the installation does not allow me to have a wire connection at the moment.
