USB Wi-Fi adapter suggestions

My (older, now) computer has started having issues with the WiFi cutting out.

I looked at the connection strength and saw it was sometimes dropping to 0, so I picked up a WiFi extender, and now it’s signal strength is usually around 70% (Windows only shows a percentage). However, even while monitoring the strength via a PowerShell script to watch the connection strength, it still drops out while the connection strength is > 70%. When it “drops out” I’ll run a speed test and see that it is basically uploading/downloading with kbps speeds instead of Mbps.

My other devices in the same room don’t seem to have any issues, so I’m wondering if my antenna or WiFi card (built in to the motherboard) are just failing.

I know PCIe WiFi cards are better, but unfortunately, as it’s an older computer (can’t even support Windows 11), the motherboard only has one PCIe slot that is in-use by the GPU.

So, any suggestions for a USB WiFi card that actually works? (Or additional ways of troubleshooting a failing wifi connection…)
