Wireless AC 9462 unstable Connection in Zotac 622 box


The Zotac Zbox 622 uses AC 9462 as Wifi module. 


As described in this article the are troubles with this module, https://uk.pcmag.com/desktop-pcs/128474/zotac-zbox-ci622-nano 

Others article report the same problem, s. https://forums.linuxmint.com/viewtopic.php?t=329032 


I bought one box, installed win10 an wifi failed very often, slowing down till connection dropping, 4 Meters from the router. My Zbox ci521 with an older Intel module works fine in the same position. 


No influence if I install the win10 or Zotac wifi driver, Version 


When there are less other Wifi nearby, things get better, so even 2 hours are possible without interruption, but there is no guarantee. 


Any valid solutions? 

Is this a general module problem?

The latest Intel Wireless and Bluetooth driver packages are at version 22.100.1, far newer than the versions you say you've have tried.  I would give them a try and see if they alleviate your issue. Use this process to do a clean install of them:

  1. If you haven't already, download - but do not install just yet - the latest Bluetooth and WiFi drivers for your adapter. Here are links for these drivers: https://www.intel.com/content/www/us/en/download/19351 and: https://www.intel.com/content/www/us/en/download/18649.
  2. Disable Internet access. Unplug Ethernet cable and/or disable wireless. Keep disabled until told to re-enable.
  3. From the Apps & Features applet, check for instances of Intel PROSet/Wireless Software and Intel Wireless Bluetooth. If none, skip to Step 6.
  4. Uninstall each instance of Intel PROSet/Wireless Software and Intel Wireless Bluetooth that is present. When prompted, choose to "Discard Settings".
  5. Manually reboot your computer, keeping Internet access disabled throughout.
  6. From the Device Manager applet, check the Network Adapters section for an entry for Intel Wireless-AC 9462 and check the Bluetooth section for an entry for Intel Wireless Bluetooth that has an intel driver associated with it. If neither is present, go to Step 10.
  7. Right click on the entry for Intel Wireless-AC 9462 and uninstall it, choosing to (checkmark) Delete the driver software for this device.
  8. Right click on the entry for Intel Wireless Bluetooth and open its properties. If it has an Intel driver associated with it, then uninstall it, choosing to (checkmark) Delete the driver software for this device.
  9. Go to Step 5.
  10. (Optional but recommended) Clean out all temporary files using the Windows Clean Disk tool. Ensure you have enabled cleaning of System Files. I recommend that you then checkmark all categories offered, even if no files currently in this category (so it leaves it set up for next invocation). (Optional but recommended) Clear each of your browsers' cache.
  11. Install the Bluetooth driver package (my rule: always do Bluetooth first).
  12. Install the Wireless driver package.
  13. Manually shutdown and reboot your computer.
  14. Enable Internet access.
  15. Test.

Hope this helps,

Hello Scott, 


I updated to the newest driver 22.100.1, the problem still exists. 


In the windows events I see the following events:


Intel(R) Wireless-AC 9462 : Interner Fehler aufgetreten.
6062 - Lso was triggered
Das WLAN-Erweiterungsmodul wurde beendet.
Modulpfad: C:\Windows\system32\IntelWifiIhv08.dll
Intel(R) Wireless-AC 9462 : Interner Fehler aufgetreten.

This error, 6062 - Lso was triggered, is very often shown. 

What models of wifi card can be used as a replacement, ac9560?

Try disabling the Lso feature; this has worked for a lot of other people. Here's what to do:

  1. From Device Manager, double-click on the entry for your Wireless card and then click on the Advanced tab.
  2. Select Large Send Offload V2 (IPv4) and set the value to Disabled.
  3. Select Large Send Offload V2 (IPv6) and set the value to Disabled.
  4. Click OK.

Hope this helps,
