I am a geek. That's not a question. But even this problem, while I have lots of experience with networks, is beyond me.
I have had this ASUS Q302LA laptop for 3 or so years now. It's wifi was totally fine back when I first got it. A year or so ago, it started having problems, though. My wifi stopped working well. When I used to get 25Mbps in my room, I suddenly started getting around 1.5Mbps there instead. I thought it was my monitors blocking the signal, so I moved them and saw a short burst of speed, then back to 1.5Mbps again. So, I thought it was the adapter.
I tried 2 different wifi adapters inside my computer, one was an older one from my previous HP laptop (the laptop was crap, so of course being HP the laptop broke twice) and I tried another from eBay. While these wifi adapters weren't anything fancy or top notch, they could still do the job, but they didn't. They also worked for a few minutes to a few hours or so, then went back to my original 1.5Mbps. Moving on, what about an external wifi adapter.
I tried the external wifi adapter, and finally I had my normal speeds! Oh, but wait, it messed up again after about a week. I was, again, back to 1.5Mbps.
What about a network reset? No good. A driver update? Success for about a minute, then back to slow speeds. Uninstall the driver and reboot? No good.
Let's get closer to the router. It works perfectly fine. Until after about 15 minutes of use it slows down and becomes unreliable, reliable, and so on. The internet near the router is shaky still. But all other devices work fine with normal speeds in my room anyway.
Maybe it was a problem with the router? Nope, all other devices work fine and no matter what settings I change, there is still a problem. I even changed the router twice!
I'm stuck. I have no clue what on Earth could be causing this problem! Thanks ahead of time for the support!
I have the same question on Microsoft Community so here's the link for reference:
