Preliminary Troubleshooting

If your wireless station cannot communicate with a computer in the Ethernet LAN when conﬁgured for Infrastructure mode, check the following:

■Make sure the access point which the station associated with is powered on.

■Make sure your wireless station is conﬁgured with the same operating radio channel as the access point.

■If you still cannot connect, change the access point and all the stations within the BSS to another radio channel.

■Make sure the BSSID is the same as the access point for a station with roaming disabled, or the SSID is the same as the access point for a station with roaming enabled.
