Analysis of the Output:
IPv4 Address: 192.168.1.20 (which seems fine for a private network)
Subnet Mask: 255.255.255.255 (this is incorrect)
This mask allows only one usable IP (itself), meaning the PC cannot communicate with other devices, including the gateway.
Default Gateway: 192.168.1.1 (which is correct for a typical home or office network)
DHCP Server: 192.168.1.1 (this confirms the network has DHCP enabled)
Solution:
The technician should change the subnet mask to 255.255.255.0, which is standard for a network using 192.168.1.x addresses.

Steps to Fix:
Open Network and Sharing Center.
Go to Adapter Settings > Right-click on the network adapter > Properties.
Select Internet Protocol Version 4 (TCP/IPv4) > Click Properties.
Change the Subnet Mask to 255.255.255.0.
Save and restart the network adapter.
Once the subnet mask is corrected, the computer should be able to communicate with the gateway and access the internet. 🚀
