What Does “Default Gateway Not Available” Mean?

Your default gateway is the device that connects your computer to the internet  usually your router.

• Internet works on phone but not on PC
  

Why This Happens

This issue is usually triggered by:

• Outdated or broken network drivers
  
• Power-saving settings turning off your adapter
  
• Corrupted TCP/IP stack
  
• Wrong IP configuration
  
• Windows 11 updates replacing stable drivers
