Criando uma rede única usando WDS - Curso Redes #18

Technological concepts & goal

• This video is the closing/continuation of a networking course episode. It demonstrates how to create a single Wi‑Fi “network” coverage area using WDS (Wireless Distribution System).
• It uses two routers/APs configured as “Master” and “Slave”, allowing devices to roam/associate across them more seamlessly (same SSID/security), without cabling between them.

Key technical warnings / misconceptions addressed

• WDS is not the same as WPS. The speaker explicitly distinguishes:
  • WPS is a feature/concept of its own.
  • WDS is what enables wireless bridging/repeater behavior.
• Many problems arise from mismatched WDS/Wi‑Fi parameters or from installers/providers configuring things incorrectly.

Hardware / feature requirements

• The routers/APs must support WDS Bridge. The speaker recommends checking the router manual/specifications for WDS support.
• WDS configuration also depends on both devices being compatible with the required WDS mode.

Network topology described (Master/Slave via Ethernet ports)

• Master:
  • Connected to the upstream Internet modem/network.
• Slave:
  • Connected via WDS (wireless bridging).
  • Typically uses LAN ports for management/configuration.
  • The video stresses: do not connect the Internet/modem feed to the Slave.

Step-by-step configuration (core procedure)

1. Turn off Wi‑Fi on the upstream/ISP router/modem
   • Helps avoid interference and preference conflicts.
2. Connect Master to the modem network
   • Perform basic Wi‑Fi setup on the Master (e.g., WPA2/WPA, SSID, password).
3. Verify Master connectivity
   • Check IP configuration (example ranges like 192.168.0.x / 192.168.1.x appear).
   • Confirm Internet access with a Speedtest.
4. Configure Slave
   • Set the Slave IP to match the Master’s LAN/subnet management rules.
   • Ensure IPs do not conflict and remain in the correct network/subnet.
   • Disable DHCP on the Slave to prevent conflicting address assignments.
5. Enable WDS Bridge on the Slave
   • Slave scans for the Master’s Wi‑Fi.
   • Selects the Master connection as the WDS target.
6. Re-check WDS/Wi‑Fi matching
   • Channel alignment and security compatibility must match.
   • Keep SSID/security consistent so it behaves like one network.

IP / DHCP rules emphasized (analysis / lessons learned)

For stability, the speaker focuses on 3 main points:

1. Use the correct IP scheme
   • Slave and Master must align in the same LAN/subnet rules for management/communication.
2. Disable DHCP where appropriate
   • Especially on the Slave.
3. Ensure WDS bridging settings match
   • WDS mode/SSID/security/channel must be compatible.

The speaker also notes that some tutorials fail to highlight these points clearly, which leads to most common WDS failures.

Testing / verification methods

Tests described include:

• Confirming the client is connected to the expected SSID/WDS target.
• Verifying the client received the expected IP address
  • Example checks include 192.168.1.x / 192.168.11.x-style ranges.
• Confirming Internet works using Speedtest
  • Throughput/performance is observed (example figures appear in the video).

Roaming behavior is also discussed: clients may connect to the “closest” AP automatically, and disconnect/reconnect can occur depending on signal strength and router behavior.

Product features / alternatives mentioned

• The speaker briefly compares WDS with using a mesh system:
  • Mesh is often better, but WDS can be a cheaper solution.
• If WDS still doesn’t provide enough coverage, they mention using a universal Wi‑Fi repeater as a fallback, with a plan to cover it in a future video.

Review / guide/tutorial outcome

• The episode frames itself as a practical guide/course result: finishing a setup that creates a “single network” using two WDS points.
• The speaker claims the procedure can solve the problem reliably when WDS/IP/DHCP configuration is done correctly.
