Hey! So about a week ago my WiFi became really slow (What I can remember is that I was trying to download something to my SD card and when i started downloading the file the download speed was unbearably slow. Not only that, I was on windows 10 and my taskbar was completely nonfunctional! Making it incredibly difficult to troubleshoot, meaning i couldn't access anything through search and the only way i could access things was by right clicking on the taskbar and choosing what i wanted to go to. I couldn't even reset my computer because it was missing a drive partition! Then, earlier today, i backed up some of my files online and reset my computer in system recovery. It took me back to windows 8.1, but i'm ok with that. So, after logging on, setting up my PC, the taskbar worked! It was expected. Yet, not all problems disappeared with the reset. The only thing left is my incredibly slow WiFi.
My WiFi on about every other device in my household is about 30 mbps. But for some reason, on my PC, under network and sharing center, The WiFi is always either at 1, 2, 5.5, 6.5, or 13 mbps. Its mostly at 1,2, or 5.5 though. Why is this? I've searched countless times online but couldn't find the answer to my specific problem. I found most commonly that peoples problems were AMD quickstream, yet my computer doesn't have anything AMD or that software. I've tried diagnosing and troubleshooting my WiFi networks and it always says "Troubleshooting couldn't detect the problem." The network connection is always from 1-3 bars. I've updated my driver for my Broadcom BCM43142 802.11 bgn Wi-Fi Adapter, but nothing seems to work. Please help! Would like a response as soon as possible and try any proposed methods and reply to anyone as soon as possible!
