Review on Cat8 Ethernet Cable, Shielded For Outdoor&Indoor, 25FT Heavy Duty 26AWG Cat8 LAN Cable, Weatherproof, With Gold Plated RJ45 Connector, 40Gbps 2000Mhz High Speed For Router/Gaming/Xbox/IP Cam/Modem by Danny Robertson

The Quality of these looks fine but I'm wondering what is actually in the shielding, What wires are actually in there if this is actually a cat 8, Or something cheaper. Ever since I plugged these in I noticed my Internet speeds from my router have been way off. I Disconnected these cat 8 cables and put on cat 5E From my Motum to my router and another one to my xbox series X. Ran the speed test again and my speed is where I'm supposed to be. It's a shame I'm way past my return for these or I would return them
