30.6 Wireless LAN Troubleshooting
I cannot access the P-2812HNU-51c or ping any computer from the WLAN
(wireless AP or router).
1 Make sure the wireless LAN is enabled on the P-2812HNU-51c.
2 Make sure the wireless adapter on the wireless station is working properly.
3 Make sure the wireless adapter installed on your computer is IEEE 802.11
compatible and supports the same wireless standard as the P-2812HNU-51c.
4 Make sure your computer (with a wireless adapter installed) is within the
transmission range of the P-2812HNU-51c.
5 Check that both the P-2812HNU-51c and your wireless station are using the same
wireless and wireless security settings.
6 Check if MAC Filter is configured to deny wireless access to certain MAC addresses
to the P-2812HNU-51c. See Chapter 7 Wireless LAN in the User’s Guide for more
information.
I cannot use WDS connection.
1 You can use WDS only when WPS is disabled or wireless security is set to “No
Security”, “WEP”, “WPA-PSK” or “WPA2-PSK”. The wireless security settings apply
to both WDS links and the connections between the P-2812HNU-51c and any
wireless clients.
2 WDS is only compatible with other ZyXEL Devices of the same model.
30.7 UPnP
When using UPnP and the P-2812HNU-51c reboots, my computer cannot detect
UPnP and refresh My Network Places > Local Network.
