Ensure all wireless devices have the same settings.
- SSID: this is case sensitive.
- Channel: the wireless channels are 1 to 11.
- Mode: the wireless mode should be set to either ad hoc or infrastructure.
- Encryption: you have these options for encryption:
- Don't use any
- Use WEP
- Use WPA
- Enable wireless access point
- If Access Control List (ACL) is enabled on your router, make sure the MAC address of the wireless adapter is included in that list.
- When configuring a router:
- The user name must include a whole address like [email protected] - NOT just "user".
- After making changes, click Apply.
- If you've enabled security and have problems connecting, disable security by setting encryption to None, then try connecting again.
