Broadband slowdown

[Johndek]

On June 15, 2022 I checked my broadband Wi-fi speed and it was 200Mbs - just a promised by my provider.  On Sept 3, 2022 I checked again and it was 44Mbs.  Had my provider come out and check and decided to upgrade me to 1Gbs and install a new modem - speed stayed at 44Mbs.  Checked all systems and found no problem - my laptop checked at 500+Mbs, my other desktop (Windows 10) checked at 500+Mbs and my iPhone checks at 500+Mbs.  

I ran all your suggested fixes and downloads to no avail.  The only thing I can think of is that I upgraded my desktop from windows 10 to Windows 11 22H2 during the period between June and Sept.  Did Windows 11 create a broadband problem on my unit? Is there another solution?  Has anyone else experienced this problem?

Any answers would be greatly appreciated.    Thank you in advance for responding.

HP does not supply drivers for Windows 11.  Please re-install drivers for Windows 10:

Updated: Your wifi adapter ONLY supports 44Mbs.

Thanks for responding.  I tried reinstalling the Windows 10 drivers and it did not help - as a matter of fact, my speed dropped to 24Mbs.  Since HP does not support drivers for Windows 11, does that mean I have to revert to Windows 10?  If that's the case, I'll scrap the machine and purchase a new desktop from another manufacturer.  I always thought HP was in the front of new technology, I guess they're not there anymore.  Again thanks for the info.
