Where do I start... It feels like I've been batteling this issue for years now to no avail. The problem is simple: My network speed on my laptop is limited to a maximum of 3Mbit/s (tested at fast.com). I have tested absolutly everything trying to solve this issue and have forgotten most of what I've tried. Anyway, here is in short what I've tried and my conclusions (that I remember): The problem is NOT with my ISP or router! Every other device in my household works fine. Only my laptop is affected. The problem is without a doubt my network card or its drivers. My network card: Realtek 8821ae Wireless LAN 802.11ac PCI-E NIC I have tested pretty much all divers that the internet can provide, be it the official ASUS and AMD websites, various driver update software or manual web searches. I have reinstalled windows from scratch multiple times to no avail. I have just recently upgraded from Windows 7 to Windows 10 in case the drivers were incompatable with win7, but that only made it worse it seems. When I used win7 then this issue came and went, occationally throttling my network speed. As I upgraded to win10 the issue became permanent. I previously dualbooted ubuntu on this machine where the issue where different in it instead would occationally drop my internet connection altogether until I manually reset the network card. One thing that currently works to alleviate the problem is to go into the device manager and uninstall the driver. This gives me about 10-15 Mbit/s download speed, which at this point is good enough (I have 100Mbit/s and other devices have achieved 50+ Mbit/s on wireless). Sadly, this only lasts about 1 or 2 minutes until it reverts to the previous 3 Mbit/s limit, as if windows automatically updates the driver or something. Please do ask for more information if needed and I'll make sure to answer them. Please help me out here, I'm just sooo burnt out on this issue.
