Focus: Wireless Networking & Troubleshooting

Learning Intention

We are learning how Wi-Fi works, key wireless standards, and how to fix common connection issues.

Success Criteria

• I can name one Wi-Fi standard (802.11n, ac, ax) and explain its speed/frequency.
• I can troubleshoot a basic wireless connection issue.

📝 Seminar Study Notes – “Wi-Fi Deep Dive”

• Standards:
  • 802.11n → 2.4GHz, 300 Mbps.
  • 802.11ac → 5GHz, 1 Gbps+.
  • 802.11ax (Wi-Fi 6) → latest, efficient in crowded areas.
• Frequencies:
  • 2.4 GHz = longer range, slower speeds.
  • 5 GHz = shorter range, faster speeds.
• Security: WPA2 (older), WPA3 (stronger encryption).
• Troubleshooting Steps:
  • Check SSID + password.
  • Reboot router or adapter.
  • Verify IP address (DHCP working?).
  • Move closer to access point.
