Basic Network Troubleshooting (DNS & IP Refresh)
When a user says, "I have internet, but I can't reach certain sites," or "Teams says I'm offline but my browser works," the issue is often a DNS or IP conflict.
Open Command Prompt: Search for cmd and select Run as Administrator.
Release IP: Type ipconfig /release and press Enter. This drops the current connection.
Renew IP: Type ipconfig /renew and press Enter. This requests a fresh address from the router.
Flush DNS: Type ipconfig /flushdns and press Enter. This clears the "phonebook" of old web addresses.
[!NOTE] This is the "magic fix" for most "Limited Connectivity" errors without needing to reboot the entire router.
