+
+|**Property**|**Value**|
+|--------|-----|
+|Channel Width for 5GHz|Auto (Access Point determines width)|
+|Roaming Aggressiveness|Medium|
+|Throughput Booster|Disabled|
+|Transmit Power|Highest|
+|802.11a/b/g Wireless Mode or Wireless Mode|Dual-band 802.11a/b/g or 802.11a/b/g|
+|802.11n/ac Wireless Mode or HT Mode|802.11ac or VHT Mode|
+|Other Advanced Properties|[more details](https://www.intel.com/content/www/us/en/support/articles/000005585.html)|
+
+- **802.11n/ac Wireless Mode or HT Mode:** determines the supported data rates/throughput mode
+  Ensure WiFi Router/Access Point supports 5 GHz and configured for 11ac mode
+  
+  - `HT=High=802.11n`
+  - `VHT=Very High=802.11ac`
+  - `Disabled=11a/g rates`
+- **Key settings related to 11ac**
+  _**NOTE:** The actual name and feature of the setting may vary depending on the AP. Check the user manual or contact your AP manufacturer for details_
+  
+  - **Channel**
+    
+    - This setting controls the channel your AP uses to communicate with client devices on your Wi-Fi network.
+    
+    - Most APs should have this set to Auto by default. We don't recommend changing this setting unless you:
+      
+      - Have a good understanding of Wi-Fi channels
+      - Know how to determine the least congested channel in your environment
+  - **Channel Width**
+    
+    For optimal performance and compatibility, enable support for all channel widths. If configured for 40MHz only or 80MHz only, this setting prevents legacy devices that support only 20MHz from connecting to the AP.
+  
+  - **(Wireless) Mode**
+    
+    This setting controls the type of Wi-Fi devices (802.11a/b/g/n/ac) that can connect to the AP.
+    For optimal performance and compatibility, enable support for all wireless modes.
+    If configured for 11ac mode only, legacy devices that support only 11n or 11a/g aren't able to connect to the AP.
