 + 
 + \\ 
 + 
 +**Toggle:** 
 + 
 +\\  ''/sbin/radio toggle'' 
 + 
 + \\  \\ 
 +

 + \\  ''/sbin/radio off''

 +**Force radio on:** 
 + 
 + \\  ''/sbin/radio on'' 
 + 
 + 
 +===== Specific Wireless chipset (2.4/5GHz) operations ===== 
 + 
 +Modern routers come with two or more chipsets/WiFi interfaces. There is usually one 2.4GHz interface and one or more 5GHz interfaces. In certain cases you might want to control a specific chipset via the command line. 
 + 
 +Once you've identified the name of the appropriate radio interface (via the [[advanced-wlanvifs|Virtual Wireless]] page): 
 + 
 + \\ 
 + 
 +{{:pasted:20221127-160308.png}}\\  \\ 
 + 
 +Do not blindly use this table. It is only an example. Router interface names may vary. For full chipset operation, refer to the "ethX" name reference of your interface(s). Once you have the correct names, you can check the status of your WiFi interface as follows: 
 + 
 +\\ 
 + 
 +For example, using "eth1" in my the above example: 
 + 
 +**Verify interface state** 
 + 
 + \\  ''int=eth1''\\ '' [ $(wl -i $int radio | grep -Eo [0-1]$) -eq 1 ] && echo "radio $int is off" || echo "radio $int is on"'' 
 + 
 + \\ 
 + 
 + \\ 
 + 
 +**Toggle interface state** 
 + 
 +\\  ''int=eth1''\\ '' [ $(wl -i $int radio | grep -Eo [0-1]$) -eq 1 ] && wl -i $int radio on || wl -i $int radio off'' 
 + 
 + \\ 
 + 
 + \\ 
 + 
 +**Force interface off** 
 + 
 + \\  ''int=eth1''\\ '' wl -i $int radio off'' 
 + 
 + \\ 
 + 
 + \\ 
 + 
 +**Force interface on** 
 + 
 + \\ \\  ''int=eth1''\\ '' wl -i $int radio on'' 
 + 
 + 
 +===== WiFi SSID-specific operation ===== 
 + 
 +In some cases, you might want to just restrict access to only one specific SSID or change settings specific to only one WiFi interface. 
 + 
 +This can be achieved as follows: 
 + 
 +First, identify the SSID virtual interface you want to control. The full list of WiFi interfaces on your router and all its sub-interfaces can be found in the [[advanced-wireless|Virtual Wireless]] menu. 
 + 
 +Virtual interfaces are always defined as: ''[ main wireless interface name ] + [.] + [number 0-3]'' 
 + 
 +For example, on this router, in the Virtual Wireless menu, we can see the  2.4GHz interface named: "wl0.1".

 +Now, let's assume you want to turn off wl1.3 which is associated to SSID "test"

 + \\ \\ {{:pasted:20221127-162109.png}} 
 + 
 + \\

 +We could perform the following tasks:\\

-Modern routers come with 2 or more chipsets, there's usually 1x 2.4GHz and 1x (or more) 5GHz chipset. In some certain case you might want to enable/disable a specifi chipset from the command line.

-{{:pasted:20221127-160308.png}}\\ + \\
-Do not blindly use this table. Check what it says on your router as it might be different. FOr full chipset operation we refer to the ethX name reference of the interface. Once you have the correct name (I'm using eth1 in my example here below), you can check the status of your wireless interface as follow:+
  
-**Verify**\\ 
-''int=eth1\\ 
-[ $(wl -i $int radio | grep -Eo [0-1]$) -eq 1 ] && echo "radio $int is off" || echo "radio $int is on"'' 
  
-**Toggle**\\ +==== Wireless SSID-specific operation ====
-''int=eth1\\  +
-[ $(wl -i $int radio | grep -Eo [0-1]$) -eq 1 ] && wl -i $int radio on || wl -i $int radio off''+
  
-**Force off**\\ +Often, a specific defined SSID operates on multiple interfaces/sub-interfaces.
-''int=eth1\\ +
-wl -i $int radio off''+
  
-**Force on**\\ +You can disable that SSID on all interfaces everywhere, as follows:\\
-''int=eth1\\ +
-wl -i $int radio on''+
  
-===== Wireless SSID specific operation =====+ \\
  
-There might be cases where you don't want to affect the full radio chipset but rather restrict access to a specific SSID. This is achieved as follow: +**Force Off**
-- Identify the SSID virtual interface you want to affect. Remember virtual interfaces are always defined as [ main wireless interface name ] + [.] + [a number 0-3] so e.g. "wl0.1". The full list of wireless interfaces available on your router and the all their sub-interfaces once again can be found under [[advanced-wlanvifs|Virtual Wireless]] e.g.\\ +
