I recently bought HP Envy laptop with Intel(R) Wi-Fi 6 AX201 160MHz built-in network adapter. Wi-Fi internet speed is problematic. Theoretical, my max internet speed provided my internet provider is 250 Mbps for downloading and 25 Mbps for uploading. I use a router set to use 5 GHz Wi-Fi. Speed on my phone is almost max supported, i.e. about 240 / 24. However, speedtest.net shows only 140-160 / 10-14 Mbps on Windows 10 installed on HP Envy laptop. I read this Solved: Re: Spectre X360 AX201 - HP Support Community - 7302389 and when I did a system restore, the speed increased and that was great, even went to 244 / 24.5 Mbps. Unfortunately, after restarting, speed was back to previous bad one. I tried system restore two times and for both cases, speed was great, but only until the laptop turns off or restarts. I tried also Ubuntu live distribution and there was very good speed, above 230 / 24 Mbps, So, it seems that this is something specific for Windows 10 or network drivers, and it's not up to hardware. Current installed drivers of the network adapter have version 18.104.22.168 from 20/10/2020. Also, I run network tests through HP PC Hardware Diagnostics app and all tests passed.
Thank you for an answer, but unfortunately, that is not the solution to my problem. I uninstalled the wireless driver as you said and installed it again, but that didn't change anything. So, please focus on what I have already explained and what I have tried many times.This is a new laptop with pre-installed Windows 10 which includes some HP tools.
If I restore my computer to a previous state (it can even be to the state from today), Wi-Fi connection speed will be great. Therefore, it does not seem to be a version of the driver is so important, which in this case is the same as before the restoring, but there is some other limitation that I cannot detect. However, if I turn off the computer and turn it on later or restart, that great speed will be lost again and reduced even over 50%. I’ve tried a lot of things, but nothing helps. Once again, this is something specific for the current installation of Windows and it does not seem like a hardware problem.
Can you help me with that? If the potential solution is to reinstall Windows, can you tell me how to do it and keep all the HP tools that were preinstalled with the newly purchased laptop? However, I would like to know the exact cause of the problem, for possible future fixes. I've tried disabling the antivirus program and temporarily disabling bluetooth, but nothing helps, except the system restoring at any point, even if it was today's state, which is absolutely the same as the current one, regarding Windows updates, driver versions and similar things.
