Windows 10 wifi slows down until reboot

Hello

i have noticed a problem with my Lenovo Legion laptop

After a while the internet connection completely slows down to the point it is pretty unusable, however a simple reboot fixes he issue until of course it slows again over time.

i've tried lots of things to rectify that i have seen online, but nothing has resolved the issue. i have all the latest window updates and network driver updates as far as i can tell. i've disable my AV and tested and that makes no difference.

Can someone help please?

Cheers

I found a very possible solution.

Go to settings - > network -> status -> change adapter options

select your wifi adapter.  right click and select "properties"

select the first "configure" button

go to the "advanced" tab.  select "preferred band" and select "prefer 5GHz band"

This will force your wireless adapter to stay on the 5GHz band of your router.

If all your devices intend to use the 5GHz band, disable the 2.4GHz band on the router (although not recommended as many other devices such as IoT uses the wider, slower band)

The BUG:

I appears that windows will constantly hunt for the stronger signal even if it is the slower signal.   For example, if you were moving around your house with your laptop, you may have started on the 5GHz band, but it picks up the 2.4GHz as stronger, and goes on there.  Your network speed instantly drops.  (this will even happen if you are stationary).  

HOWEVER, even if you go back to an area with strong 5GHz coverage, windows does not return to the 5GHz speeds.  For whatever reason, the speed stays limited to the slower output.  That's why if you reboot or turn off and on the adapter, it resets it and you get max throughput again.

Microsoft should really fix this bug.

    My legion desktop pc had been doing this exact same thing for a week now.. I first thought it was the modem so I bought a new one and still doing it.. Only thing that will fix is is the restart the pc. But that only lasts for a while n back to slow speeds.. Im getting 8mbps down and  0.8 up when I have the 400 plan. I'm hoping it's just a software issue.  I'm hooked up using a cat 8 cable from my router

    It seems lots of folk are experiencing this problem and its a disgrace that it hasnt been addressed bu Microsoft, but then again thats par for the course . impossible to,get them to addess basic flaws bit at the same time they continue to “improve” Windows with bags of tricks that most folk could not care less about !

    Unfortunately it seems to be the case! We'll suffer it till we may one day get fed up of it and move to IOS world, which my whole family has done already and are satisfied with it.
