Global BG Scan blocking - Setting missing

Airwave

Hi,

 

I've noticed since driver version 22.150.0 the advance setting 'Global BG Scan blocking' has been removed and therefore can't be changed. I've just tried version 22.160.0 and the setting is still missing (the setting is available in version 22.140.0).

 

This there a reason for removing this setting? Can the setting be added back as the default setting is bad for latency and I would like to be able to change the default setting from 'Never' to 'Always'.

 

Thanks

Hello Airwave,


Thanks for waiting for a response.


Several changes/improvements were implemented in 22.150 to reduce/eliminate the impact of BG Scan on user experience. In other words, a background scan is now performed in a much more efficient manner and reduces the impact on other activities that the user might be performing. With the new improvements, the setting 'Global BG Scan blocking' is no longer needed in the latest driver 22.150. If you need to Roam you can try using a background scan, which is typically performed in order to figure out what other APs are available in the vicinity.

Hello Airwave,


I appreciate your response. The information provided has been helpful.


I still want to confirm some information to better assist you.

  • Can you try your motherboard manufacturer driver and check if the Global BG Scan blocking option is there?
  • Is this the original adapter that came pre-installed in your system or have you changed/installed a new adapter recently?
  • To have more complete information about your system, please, create a report using the Intel System Support Utility (Intel SSU)

Hi Jean,

 

My motherboard never came with a WiFi adaptor. I recently bought and installed a new adaptor.

 

Please find attached a report of my desktop PC.

 

My work laptop, a Dell Latitude 5420, has an Intel AX201 WiFi card and currently has the generic Intel driver installed, version 22.140.0. The setting 'Global BG Scan blocking' is available to change. However I just installed version 22.150.0 and the setting isn't listed in the advance settings.

 

Thanks

Hi there,

I have setup another thread on this - but I'm finding the latest driver with this setting removed STILL causes periodic issues (every 10 minutes) when using applications that are highly sensitive to latency (moonlight game streaming in my example).

The only workaround I have is to downgrade the driver to when the block Global BG Scanning option is still available, and then set it to always.

Is there any possibility of Intel either adding this option back, or fixing the latency that seems to be caused by the BG Scanning?

My thread with more detail around this issue is here: https://community.intel.com/t5/Wireless/AX210-Periodic-Lag-Spike/m-p/1566089#M52106
