A new wireless client that is 802.11 compliant cannot connect to a wireless network given that the client can
see the network and it has compatible hardware and software installed. Upon further tests and investigation it
was found out that the Wireless Access Point (WAP) was not responding to the association requests being sent
by the wireless client. What MOST likely is the issue on this scenario?
A.
The client cannot see the SSID of the wireless network
B.
The WAP does not recognize the client’s MAC address.
C.
The wireless client is not configured to use DHCP.
D.
Client is configured for the wrong channel
C.
Answer: D Client is configured for the wrong channel.
The client can only send association requests once authenticated. So, ‘A’, ‘B’, and ‘C’ are ruled out. The association requests are sent from the client to ‘an’ AP that the client wishes to associate with. For the association to happen, both the AP and client need to be on the same channel. If there is only one AP on the WLAN network and the client is on a different channel, the AP assumes the association request is not meant for it, and ignores the requests.
C. The WAP does not recognize the client’s MAC address
D
‘The client is using the same hardware and software as everyone else”
Which means being on the wrong channel is ruled out.
“Client can see the network”
SSID not broadcasting is ruled out.
DHCP has nothing to do with Association probes being dropped.
That leaves B. MAC Filtering is common with WAPs. It is marked at B on every other dump site as well.
If MAC filtering is enabled, it will ignore Association requests. This is most likely.
