Parsing iw wlan0 scan output, wlan_scan.sh #!/bin/sh sudo iw dev wlan0 scan | awk -f wlan_scan.awk | sort. wlan_scan.awk /^BSS/ { mac = gensub ( /^BSS[[:space:]]*([0-9a-fA-F:]+).*?$/, "\\1" iw phy phy0 interface add wds0 type wds iw dev wds0 set peer <MAC address>. In order for this to work the driver must implement the cfg80211 callback set_wds_peer (). mac80211 implements this callback, so the respective mac80211 driver would just need to support WDS type interfaces.
How do I scan for Wireless Access Points?, sudo iwlist wlan0 scanning | egrep 'Cell |Encryption|Quality|Last iw dev wlan0 scan : Scan for access points reachable via interface wlan0. iw dev wlan0 scan freq 5785 5200 ssid test1 freq - WLAN frequencies (refer to: < WLAN channels >) The EVM sends probe request when it needs to obtain information about AP's in range. When an AP gets this request, it replies using probe response containing the AP information (such as SSID, Channel, Capabilities and other information).
en:users:documentation:iw [Linux Wireless], iw wlan0 scan | egrep 'SSID|signal'. You can post-process this for SSIDs you are interested in.

Retrieving Specific SSID's Name,Quality and Signal Level using iwlist, You can post-process this for SSIDs you are interested in. Say you want SSID1 and SSID2, then you can do iw wlan0 scan | egrep 'SSID|signal' | egrep -B1 iw wlan0 scan | egrep 'SSID|signal' You can post-process this for SSIDs you are interested in. Say you want SSID1 and SSID2, then you can do. iw wlan0 scan | egrep 'SSID|signal' | egrep -B1 'SSID1|SSID2' The -B1 displays the line before the match, because in the scanning output, the signal strength comes before the SSID.

Retrieving Specific SSID's Name,Quality and Signal Level using iwlist, iwlist INTERFACE scanning essid SpecificESSID | grep ESSID,Signal. iwlist INTERFACE scan | grep 'ESSID:"SpecificESSID"\|Signal level' - This almost worked sudo iwlist wlan0 scanning essid ESSID | grep Channel | head -1 | awk -F: '{print $2}' Make sure to replace ESSID with your essid: For the address, (as requested in the comment) try this:
command line, iwconfig wlan0 2> /dev/null | awk -F: '/Mode:/ {print $2}' | awk '{print $1}' sudo iwlist wlan0 scanning essid ESSID | grep Channel | head -1 $ sudo iwlist wlan0 scan | perl -nle '/ESSID:(.*)$/ && print $1' This causes perl to run the command ( -e ) on each line of the input ( -n ) and adds a line feed at the end of each line ( -l ). The command is a regex which searches for ESSID: and captures the remaining line ( (.*)$ ).
iwlist: Get more detailed wireless information from a wireless , scan[ning]: Give the list of Access Points and Ad-Hoc cells in range, and optionally a whole bunch of information about them (ESSID, Quality, Frequency, Mode. By default, the way scanning is done (the scope of the scan) is dependant on the card and card settings. This command take optional arguments, however most drivers will ignore those. The option essid is used to specify a scan on a specific ESSID. The option last do not trigger a scan and read left-over scan results. freq[uency]/channel

How do I scan for Wireless Access Points?, sudo iwlist wlan0 scanning | egrep 'Cell |Encryption|Quality|Last beacon|ESSID' should help. It's the combination of sudo (run as root, do Iwconfig is similar to ifconfig, but is dedicated to the wireless interfaces. It is used to set the parameters of the network interface that are specific to the wireless operation (the wireless frequency, for example). Iwconfig may also be used to display those parameters, and the wireless statistics (extracted from /proc/net/wireless).

How to discover the hidden ssid of a WiFi network with these simple , One security mechanism is to hide the Wi-Fi network SSID. This is an obsolete security measure since a hidden wireless network name can be In this article, we will debunk this obsolete security mechanism and we will show you several ways to find out a hidden network’s SSID.
