Hiding neighbors' wireless routers • ITCRS

Windows displays visible wireless networks nearby [WLAN] Wireless Local Area Network. Wired networks are called LAN. WLAN can be hidden in Windows, Not important but comfortable. Hiding neighbors' wireless routers is done by filtering out the WLAN nearby that you don't want to see. You do it with just a few commands..

Wi-Fi is a common alias for WLAN.

Start a command prompt (administrator).
Type this command to see the names of WLAN [Wi-Fi] which is nearby.

netsh wlan show networks

Type the following command and replace ”WLAN name” with the name of the WLAN that you want to hide.

netsh wlan add filter permission=block ssid="WLAN-namn" networktype=infrastructure

To restore the network in the list again, byt ut add against delete in the above command.

If you forgot which filters you've added, you can type

netsh wlan show filters

In my LAN, it looks like this:

C:\WINDOWS\system32>netsh wlan show filters

Allow list on the system (group policy)
---------------------------------------
    <None>

Allow list on the system (user)
-------------------------------
    SSID: "SVARD24", Type: Infrastructure
    SSID: "SVARD50", Type: Infrastructure
    SSID: "TV-50", Type: Infrastructure
    SSID: "TV-24", Type: Infrastructure

Block list on the system (group policy)
---------------------------------------
    <None>

Block list on the system (user)
-------------------------------
    SSID: "Tele2_35acfb", Type: Infrastructure
    SSID: "DIRECT-jUC48x Series", Type: Infrastructure
    SSID: "DIRECT-EC-HP OfficeJet Pro 6960", Type: Infrastructure

Another option is first to add your own WLAN with allow and then filter out all other WLAN.

netsh wlan add filter permission=allow ssid="wifi-namn" networktype=infrastructure
netsh wlan add filter permission=denyall networktype=infrastructure

To remove the filtering of all other WLAN, type the commissar with delete.

netsh wlan delete filter permission=denyall networktype=infrastructure

Note that no name of [ssid="wifi-namn"] to be used when the command contains "permission=denyall".
