Want A Constant Readout Of Who's Connected To Your LAN?


Do you know who's currently connected to your network?  Are you sure it's just your PC and your router?  What about all those other IP-capable devices in your house?  And what about all those other IP-capable devices in houses in your street or your block?  Are they connecting too?  

Your router can probably give you such information, but it requires logging into the router each time and the list doesn't update automatically.  Which are just 2 of the reasons why I rather like Wireless Network Watcher, from Nir Sofer's excellent "nirsoft" web site.

Despite the name, Wireless Network Watcher will watch any small network that consists of both wired and wireless clients.  In the example shown below, it's picking up routers, IP cameras, smartphones and more.  You can show all sorts of useful information columns, such as the MAC address of all devices and the date they were first detected.  Plus, as mentioned, the display updates automatically, so keep it open on your desktop to watch users and devices come and go.

The easiest way to try WNW is to download from http://www.nirsoft.net/utils/wireless_network_watcher.html (click on the Download In Zip File link from about two thirds of the way down the page).  This is a portable version that's only around 0.3 MB to download, needs no installation, and runs on all recent versions of Windows.  The program is malware-free according to VirusTotal and Web of Trust.  If you don't find it useful, just delete the unzipped folder and you're done.

Just installed Wi Fi Guard on my Linux Mint 17.1 PC and it works great.

Many users are not aware they they don't need to install software to get this information. While this program is convenient it didn't get everything correct compared to the reporting from my WiFi router. WiFi routers can provide lists of connected devices including whether they are connected by WiFi/WLAN or cable/LAN. Provided you have administrative access for the router then you can check this at anytime. The WiFi router is also where you block specific devices from accessing your network.

Good Idea Remah.
I just logged into my router and confirmed each device connected to it and renamed them for easy reference in the future.


Thank you VERY MUCH!

I missed that gem on my occasional visits to NirSoft.

What a surprise, I have at least 8 active IP addresses That I don't have a clue of!

Thanks again, lots to investigate.

Remember well this app .. used it for many years and it is still installed but only used on demand. I for whatever reason migrated to WiFi Guard to alert me to when anyone new is on my network .. check it out at https://www.softperfect.com/products/wifiguard/
