- Ensure the VAP11S-232 is successfully connected to the upstream WiFi network (check status LEDs in the web interface).
- Verify the WiFi password and security settings are correct.
- Check if the upstream router has internet access.
- In Router mode, ensure WAN settings are correctly configured (DHCP, Static IP, PPPoE).
- Slow Connection Speed:
- Ensure the device is placed in an optimal location, ideally 10-40 feet from the main router, away from obstructions and interference.
- Check for sources of interference (e.g., microwaves, cordless phones, other 2.4GHz devices).
- Verify the upstream WiFi network is performing well.
- Ensure your connected devices support 802.11n for 300Mbps speeds.
- LAN Connector Issues:
- Ensure Ethernet cables are fully seated and click into place.
- Try different Ethernet cables to rule out cable faults.
