Changing Subnet Mask to Broaden Connectivity
- Open Command Prompt (Windows + R → type cmd → Enter) or Terminal on Mac.
- Run ipconfig /all (Windows) or ifconfig -all (Mac) and note the IPv4 Address, Subnet Mask, and Default Gateway.
- Compare the subnet masks for your computer and phone to check if they are in the same network.
If the Subnet Mask Needs to Be Broadened:
-
Access Command Prompt as Administrator
- Right-click on Command Prompt → Run as Administrator.
- Modify Subnet Mask
Run the following command:
netsh interface ip set address "WIFI NAME" static <Your Computer IP> 255.255.0.0 <Your Gateway IP>
- Replace <Your Computer IP> and <Your Gateway IP> with the respective values.
-
Verify the Change
- Run ipconfig to confirm that the subnet mask now reads 255.255.0.0.
-
Test the Connectivity
- Run ping <VoIP Phone IP> to check if the computer can now communicate with the phone.
Reverting to Original Subnet Mask
-
Restore the Subnet Mask
Run this command:
netsh interface ip set address "WIFI NAME" static <Your Computer IP> 255.255.255.0 <Your Gateway IP>
- Switch to DHCP (Optional)
To let the network automatically assign an IP:
netsh interface ip set address "WIFI NAME" dhcp ipconfig /renew
Notes
- This change is temporary and intended for troubleshooting. Revert to the original settings once the task is complete.
- Ensure the phone is powered on and connected to the network during this process.
- If issues persist, check the physical connections or consult the network administrator.
Current Wi-Fi Configuration (based on your screenshot):
-
Wi-Fi Adapter Name: Wi-Fi
-
IPv4 Address: 10.160.13.186
-
Subnet Mask: 255.255.254.0
Default Gateway: 10.160.12.1
