The router and switches send out broadcast ARP requests to all the MAC addresses on the network asking them to respond with their IP addresses.
These tools are basically used in Penetration Testing of Wireless Networks and can be used to get to know who is in the Network by knowing their IP Address and MAC Address.ĪRP (Address Resolution Protocol) is used to map MAC addresses to IP addresses on an internal network. You can Use a number of tools for thus task such as Netdiscover, arp-scan, nmap and even WireShark. On Linux you can do the following: Getting MAC Address of Devices connected in your network So, I thought It would be useful to answer for Linux Platform too. Sit next to your repeater with your laptop.Well Everybody answered the Question for Windows Platform only. To analyze if your Router is working, try watching the output while switching the repeater on and of. Tx excessive retries:0 Invalid misc:173 Missed beacon:0īut both only show the connection to the wlan networks BSSID Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Retry short limit:7 RTS thr:off Fragment thr:off Mode:Managed Frequency:2.462 GHz Access Point: DC:9F:DB:F1:C2:88 Wlp1s0 IEEE 802.11bgn ESSID:"yourWLAN-SSID" On top you see the mac address dc:9f:db:f1:c2:88 which is the same that is shown on iwconfig $device Which will show something like: Station dc:9f:db:f1:c2:88 (on wlp1s0) Watch -d -n0,5 iw dev $device station dump On Linux, you can scan the connection with device="$(ip -o -4 route show to default | awk '')" If you're on Android you can use Apps like "WiFi Analyzer" which will also present you with the BSSID. You'll see all SSIDs listed and if a SSID has multiple BSSIDs - as it will if it's using a repeater - you can look at those BSSIDs if you hover over the SSID with your mouse. Once installed and started, go to "Tools"->"NSM WiFi Management". However, I found a tool which will show you the available BSSIDs and make it possible for you to connect to a specific BSSID: checkout NetSetMan. I was not able to display the BSSID which is currently used (eventually someone here is aware of such a built-in command). While I was able to find a command for windows which will show you all the known BSSIDs of a SSID: netsh wlan show network mode=BSSID
So, in order to tell to which device you're connected, you have to find a way to display the BSSID you're (currently) connected to. However, it will always have a different BSSID (think of it as of the MAC address of a network interface).
When using a repeater the repeater usually will have the same SSID as your WiFi AP.
