I got a new monitor somewhat recently, and I have noticed it causing interference with my wifi card (Ax210, not sure what brand). The wifi gets really slow (like 1/10 speed, sometimes dropping connections) when the monitor is plugged in and goes back to normal when unplugged. I’ve tried multiple hdmi cables but it still does it. I know you can buy antennas that can be moved, but I’m not sure where to start looking for them. Does anyone have any recommendations or info?
Edit: solution was putting aluminum foil around GPU Iowa and cable
Any omnidirectional antenna should be fine. You’ll want to either get one for each antenna connection or find one that has the same number of connectors as your card.
Generally, longer antennas mean more sensitive reception and probably better transmission.
