Solved: Wireless AC 9560 - Wifi Connections Rejected - Page 2

StefanoBordoni · ‎09-07-2020

I had several issues on my notebook ASUS GL703GM with Windows 10 Pro 64-bit with all lastest v2004 updates.

connection laziness at the system startup.
I wasn't able to connect to 2.4ghz wifi networks anymore.
I wasn't able to change the router with the same wifi settings.
and finally, I cannot connect to any known wifi. It continues to ask me the password...

I reset connections, TCPIP stack... but nothing.

My solution was uninstalling and removing wifi drivers until the Windows 10 2004 64-bits built-in ones (v21.10.2.2).

[<win>+x, select Device Manager, select the wifi card, right-click, select uninstall, and check 'remove drivers']

With these drivers, everything is working fine without any problem.

Then Windows Update applied v21.80 and the problems rose again.

Again I downgraded to v21.10.2.2 by the device manager, and the problems disappeared again.

As far as I could see, these problems are present at least in these versions:

21.40
21.80
21.90
21.110
21.120

A last detail that might help is that I have Core Isolation enabled.

Several days later, connection problems suddenly popped up... and I was forced to roll back to root drivers.

Yesterday I tried the latest Wifi drivers (22.30 64 bits) and they have the usual connection problems (on both 2.4 & 5ghz).

Again I had to roll back to root drivers...

Then I gave a look at the Reliability History report and I noted that I have a problem with Window Wireless LAN 802.11 Extensibility Framework crashing during the startup.

Looking at the Event Viewer I discovered that it is something related to INTELWIFIIHV08.DLL (found in my 'System32' folder).

After a short investigation, I discovered that it is a file included in the root driver package but not in the latest drivers.

I also noted that these crashes also occurred during my driver update test...

Then I re-installed the latest drivers, and I renamed the DLL.

After the reboot, my WiFi connection problems disappeared.

Up to now, the device appears working, fast, and responsive...

...Maybe I am lucky this time.

I have exactly the same problem. But the solution described does not work for me. I also found the INTELWIFIIHV08.DLL under System32. Which file has to be renamed? I would be very grateful for a hint. Thank you very much!

StefanoBordoni · ‎05-06-2021

In my case, I renamed that file in something like (*.dll_) and rebooted.

This solved my problem.

ps: after 4-5 weeks, I deleted the renamed file.

StefanoBordoni · ‎06-22-2021

In my case,

I installed the latest drivers
I went to the system32 and I renamed "INTELWIFIIHV08.DLL" into something like "_INTELWIFIIHV08.DLL_" (in this way you can always restore it with minimal effort).
reboot.
from this point, my WIFI started to work fine

It is about 3 months that I haven't connection problems anymore.

(after the first 2 running-fine weeks, I also deleted the renamed file)

Good luck

StefanoBordoni thanks for your replies.

I tried exactly these steps for several times without success.
Driver Version 22.50.1.1 on HP ZBook 17 G5 with Windows 10 Enterprise 21H1

Downgrade to driver version 21.10.2.2 = everything works fine.

Using a Ubuntu Live CD = everything works fine.

Should anyone still have an idea, I would be very grateful.
HP Support couldn't help me, so the Intel Community is my last hope.

StefanoBordoni · ‎07-08-2021

... if you didn't already do, you can try the following steps:

starting from v21.10.2.2, install latest drivers
rename the file
reboot
try your wifi
if it still doesn't work, you can try a 'network reset' from 'network & internet' settings (at the end of the page)
reboot again
try your wifi

If it still fails, you can try to look for some evident problem from Reliability Report.

StefanoBordoni · ‎08-05-2021

Sometimes the antivirus might be corrupted or unstable, and removing it to re-install it from scratch can be a good idea.

Another idea can be viewing again the Reliability History report and look for any unusual event.

Another step I took when struggling with my wifi card was to buy a USB WiFi card as an 'option omega' solution.
The interesting side is that it is something you can use on any PC.

It took a LOT of working with the Intel support engineers but Intel was able to identify the problem with the 9560 driver and will be releasing a fix for this in November, 2021 driver update is what I was told.

StefanoBordoni · ‎09-29-2021

Wow. Great job!!!

StefanoBordoni · ‎11-17-2021

New drivers are published today.

The change lot is not so clear but let's hope they include the fix.

William_2021 · ‎11-17-2021

The Intel Tech said the fix will not be out until Release 22.100.0. So I'm still waiting.

StefanoBordoni · ‎11-17-2021

hmmm... it sounds like something around December/January driver release.

StefanoBordoni · ‎01-06-2022

Finally v22.100.0 are published... and they seem working smoothly (for now).

PS: the funny thing is that 3 weeks ago I changed my flagship notebook ... with no Intel HW inside.

William_2021 · ‎01-06-2022

Yes, Very similar story with me. but Glad it's working for now.

StefanoBordoni · ‎01-07-2022

we spoke too early...

After only a day, the problem is again here.

I will revert to v21.80...
