Windows 10: Latest Intel 20.70.21.2 drivers drop in throughput speed

hi

just a heads up, i just updated to 20.70.21.2 yesterday and noticed a massive drop in wireless performance.

same desk where i keep my laptop, i noticed internet was slow today, upon testing i noticed that speed dropped from 80-85 to a mere 40 mbit after 2 minutes the PC was on. touched a few settings, all the same, checked ethernet with the cable and still i could get the proper speed here so 95-100 mbit. tested on my smartphone and i get also 80-85 mbit.

downgraded to 20.70.19.1 and works normally. speed stable to 80-85 mbit.





so yes downgraded and informed intel about it with their feedback thingie.

keep an eye on that!

- - - Updated - - -

hmhm now it happened also with the old driver that speed drops to 40 mbit, i am confused. what is going on? is it windows10 then?

- - - Updated - - -

it seems i found the culprit: it's the bluetooth - when bluetooth is on, the wireless speed is affected by 50%. i tested with old drivers etc but it seems to be the same thing.

shall i rest and just disable bluetooth or there's a smarter way? change wireless channel? some setting on bluetooth? cheers

Can't update to latest intel drivers

Hi,

Thank you for posting your query in Microsoft community. We are glad to assist you.

To assist you better, I would like to know the make and model of the computer.

The issue you are facing is probably with the drivers update. I would suggest you to uninstall and reinstall the latest updated drivers.



Please follow the below steps to uninstall the drivers:

1. Press Windows + x key.

2. Select Device manager.

3. Locate the driver.

4. Right click on the driver and click on uninstall.



Download the latest drivers from the manufacturer website and install it on compatibility mode and check.

Refer the steps to install a driver in compatibility mode:

a. Right click on the setup file of the driver and select
Properties

b. Select Compatibility Tab.

c. Place a check mark next to Run this program in Compatibility mode
and select the operating system accordingly from the drop down list

d. Let the driver to install and then check the functionality.

If the issue still persists you can try and install the latest chipset drivers
from the computer manufacturer website and check.


Hope this helps. Keep us posted on the status of the issue and we will be glad to help you further.

 

Latest Intel Management Engine Driver

It was the one from #20, I've tried the one you suggested and it says

Intel 495 (Ice Lake-U PCH-LP Premium)

Yep that's the one I've got. I've got the latest drivers off HP but I'm having a complete nightmare trying to solve this problem here

USB device malfunctioned

and thought if I could try some generic intel ones in case they have some bug fixes that HP haven't rolled out yet.

should it be Z490? I can't see that at all in either application. I've attached pictures in case I'm being completely blind!

 

Drop in Speed for my Intel 900p after installing Windows 10

Greetings,

It is no secret that with the recent microcode updates to protect consumers from the SPECTRE and Meltdown issues, there is generally expected a slow down in CPU processing speeds and SSD performance. Myself I have noticed that my Intel 900p SSDs were losing
about 33% in Q1 random 4k read/writes. Prior to all these updates I would get 300Mb/s in Q1 Random 4k read/writes. Once the new microcode was introduced that dropped to anywhere between 180-200MB/s.

Well the other day I did a fresh install of Windows 10 build 1809. Before installing anything I checked out my speed using Crystal Disk Mark and amazingly, my speed was back to the original 300Mb/s mark. I went through my normal installation process and
somewhere during installing my motherboard drivers, my speed dropped back to the 200Mb/s mark. Perplexed I was wondering what program or driver might be causing this drop? So I started over and installed WIndows again, then the Intel Chipset, Intel MEI,
Motherboard drivers, Intel IRST, ect. What I found was after about the 4th or 5th boot, regardless what order I installed these drivers, the speed of my 900p would drop upon the next reboot.

As I said I changed things up, installing the IRST driver first, audio second, ect. The next time, MEI first, LAN second, ect. Regardless of what I installed at the 4th or 5th boot, the speed would again drop. It seemed to coincide when Intel's Turbo
Boost window would pop up for the first time. Anyone that has installed Windows 10, knows that the Intel Turbo Boost doesn't load up immediately but takes a few boots to pop up at start up. So I thought that this might be the culprit.

I went into my BIOS and disabled the Turbo Boost and reinstalled Windows. This time all i did was reboot 5 times, installing nothing but CrystalDiskMark. Upon the 6th boot, the speed dropped again. I then repeated this installation except this time I
changed the group policy of installing Windows updating, basically turning Windows updates OFF or not to install without my permission. Same thing after the 5th reboot, my speed would drop.

I would really like to have my original speed of my Intel 900p back. A 33% drop is quite noticeable. The fact that I'm seeing the original speed after a fresh install made me quite happy and now I'm quite perplexed.

So my question is simple. Why is this happening? What happens in those first 5 boots that changes Windows so my Intel 900p loses 33% of its speed? Is the microcode meant to fix SPECTRE/Meltdown not enabled in those first 5 boots? Do I have to install
an INTEL driver for my 900p for Windows 10?

I am asking because a friend with a 905p has been able to do a fresh install and is retaining his speeds. He and I have the same motherboard, GPU, RAM.

**NOTE** I have downloaded the most up-to-date drivers for Intel Chipset, MEI, LAN, IRST, Audio, Bluetooth, Wifi, (all motherboard drivers)

Help?
