Question External SSD causes Slow WiFi

Recently I got a NVME enclosure and a 2tb SSD and if I plug it into the USB A ports on the back of my PC the wifi speeds are like 3mbps and 200 ping, but If i plug it into the front USB it works?

sound like interference

If you have a PCIe WiFi card with external antenna or a USB WiFi dongle plugged into the back of the computer, right next to the NVMe enclosure, this is a classic case of EMI.

As you've already discovered, separating the offending NVMe enclosure and moving it around to the front of the computer has improved WiFi speeds.

Even better would be an Ethernet connection from the PC to the broadband router if they're in the same room. Ethernet is practically immune from this type of EMI.

Ah ty i guess that makes sense and yes I have antennas from the built in wifi on the mobo would also explain why on my other PC using ethernet powerline I didnt have the problem

Turns out this wasnt the issue but updating the bios and chipset fixed it
