Yes, your computer running GlassWire has to be able to see the device. If your computer is cable connected and your phone is wireless connected then you may not be able to see it.
If you want to, here is how you can ping all the devices on the subnet that your computer is on.
Open a Windows command window:
- Press the Windows key to get the Start menu
- Type in “Command” to search for the “Command Prompt”.
- Select “Command Prompt”
Another way to do it is:
- Press Windows key + R
- Enter “CMD”
And a third way to do it is:
- Right click on the Start menu icon, normally at the bottom left of the screen
- Select “Command Prompt” from the menu
A new Window should open for you to enter commands. See the example below:
You need to know the IP address range for the local subnet. The IP address is four parts and you need to find out the first three parts:
- If you know your router/gateway IP address, e.g. 192.168.1.1, or your PC IP address, e.g. 192.168.1.9, then you know the all the addresses will start with the first three parts of that address, e.g. 192.168.1.
- If you don’t know those addresses then you can enter IPCONFIG and read the “Default Gateway” or “IPv4 Address” to get them, as shown below.
Now you can ping all addresses from 0-254 (you don’t need to ping 255) by entering the following command:
for /L %i in (1,1,254) do ping -n 1 192.168.1.%i | find /i “TTL”
Any IP address that returns a reply will be displayed. In my example below, 192.168.1.1 has a reply but 192.168.1.2 and 192.168.1.3 do not.
You can check the IP addresses that reply against the local network DHCP on your router and the GlassWire Device list.
