Reverting Windows doesn't affect my Wi-Fi drivers or card.
Last night I updated my Windows. I have a Qualcomm Wi-Fi card with its driver. My router supports speeds up to 10Mbps, but after the update I’m only getting around 400Kbps. I’m only seeing the built-in speed when sitting close to the router. After a driver update, nothing changed. I reinstalled the driver again but still had no improvement. I ran some troubleshooting and it fixed itself automatically, yet the speed didn’t rise. This matches what I mentioned yesterday. I reverted the update and it seemed to work, but after reinstalling my AMD graphics drivers it started again. Now plugging in the charger doesn’t connect me to Wi-Fi at all—Wi-Fi works fine when I unplug it. Should I restore Windows to its original version? Please help, I can’t play Fortnite.
I dislike strange issues like this. But it might be several things. I’m guessing you’re using a 2.4GHz network. Are there any devices connected between your router and your computer? Such problems usually fix themselves. You could try waiting a night. Sorry—I’m not very familiar with this topic.
Consider trying to release and renew the IPv4 address. It might not be effective, but it’s worth a try. I’ll go online for you. In the meantime, if you have an Android device, you can connect your Wi-Fi to your laptop using a USB cable. This seems like a hardware problem, though plugging in your charger makes it fail.
Consider reverting the update. It might be possible to do that in recovery mode or whatever method is available.
I identified the problem—it was a glitch in the power plan. I changed it from max performance to balanced and adjusted the settings. Now everything runs smoothly. I'm hoping the upcoming Windows update will resolve this issue.
