WiFi performance decreases significantly under high demand?
I've got a desktop with a wireless adapter in my PCIe slot. Recently, I've noticed my Wi-Fi drops significantly during downloads when I also use the internet for browsing or streaming. I'm sure it's not the router since my phone and other devices still connect properly. I have to toggle Windows Wi-Fi settings, enter the SSID, or even restart the computer, which is becoming frustrating. Normally, I experience fewer drops—only during downloads and other activities. My maximum download speed is just 6 Mbps, so it's not a lot of data. I've never had this issue with my old machines (an i7 920 with a gigabyte motherboard from 13 years ago and a 3570k + Z77 motherboard), both using the same adapter. I recently switched to a Ryzen 5600 + B550 motherboard, hoping it won't cause the problem. The adapter has the latest drivers, I've restarted my PC, reinserted the card, tightened the antennas, but nothing works. It's really strange and I don’t even know how to search for solutions online. Many results mention laptops, but I'm not sure if anyone else has faced this issue.
PCI-based Wi-Fi adapters are terrible. I’m saying they’re designed to push you toward paying extra for physical Ethernet installation. I’d try switching the adapter to 2.4 or 5GHz and see if it improves things. For my desktops, I usually use a USB Wi-Fi dongle with a long USB cable.
There might be several problems. Your device could be overheating, which the AC WIFI chipset is known to run hot with. Outdated or poor drivers might also be causing issues. Weak signal strength or interference can lead to complications. A defective WiFi adapter could be another factor.
This card consistently maintains stable connections during downloads and while browsing or streaming on older systems. It seems unusual for it to behave differently now, right?
Basic rule about computers – it’s normal for things to behave unexpectedly at any moment. I often wonder if an OS update was released, whether the “latest driver” is actually better or just different, since newer versions aren’t always superior and bugs can appear. When troubleshooting issues, I usually look into the WiFi chipset itself and seek drivers from the chip manufacturer instead of the card manufacturer.
