1. No Internet Connection (Wi-Fi Connected, But No Internet)
Possible Causes:
- ISP (Internet Service Provider) outage
- Router/modem malfunction
- IP address conflict
- DNS server issues
Fixes:
- Restart your modem and router: Unplug for 30 seconds, then plug back in.
- Check with your ISP: Use mobile data to visit your ISP’s status page.
- Renew IP address:
- On Windows: ipconfig /release then ipconfig /renew in Command Prompt
- On macOS: Go to System Preferences > Network > Advanced > TCP/IP > Renew DHCP Lease
- Change DNS servers: Try Google DNS (8.8.8.8, 8.8.4.4) or Cloudflare (1.1.1.1)
2. Dropped Wi-Fi Signal
Possible Causes:
- Weak signal due to distance or obstacles
- Interference from other devices (microwaves, cordless phones)
- Outdated router firmware
3. Slow Wi-Fi Speeds
Possible Causes:
- Network congestion (too many devices)
- Bandwidth-heavy apps (streaming, downloads)
- Outdated hardware
Fixes:
- Limit background apps: Pause downloads or streaming
- Upgrade your router: Especially if it’s older than 5 years
- Use Ethernet for critical devices
- Enable QoS (Quality of Service): Prioritize traffic for work or gaming
- Scan for malware: Infected devices can hog bandwidth
4. Wi-Fi Keeps Asking for Password or Won’t Connect
Possible Causes:
- Incorrect password saved
- Router security settings changed
- Device software issues
Fixes:
