Fixing common WSS setup problems
Table 1 contains remedies for some common problems that can occur during basic installation and setup of a WSS.

Software or a web browser
(if you are using Web
View) warns that the
WSS’s certificate date is
invalid.
The switch’s time and date are
currently incorrect, or were
incorrect when you generated
the self-signed certificate or
certificate request.
1. Use set timezone to set the time zone in
which you are operating the switch. (See
“Setting the time zone” (page 139).)
2. Use set timedate to configure the current
time and date in that time zone. (See
“Statically configuring the system time and
date” (page 141).)
3. Reconfigure the administrative
certificate(s). (See “Managing keys and
certificates” (page 443).)
4. If you have already configured a certificate
on the switch for authentication by network
users, you must recreate this certificate, too.
WSS does not accept
configuration information
for an AP or a radio.
The country code might not be
set or might be set for another
country.
1. Type the show system command to display
the country code configured on the switch.
2. If the value in the System Countrycode field
is NONE or is for a country other than the
one in which you are operating the switch,
use the set system countrycode command
to configure the correct country code. (See
“Specifying the country of operation”
(page 229).)
Client cannot access the
network.
This symptom has more than
one possible cause:
• The client might be failing
authentication or might
not be authorized for a
VLAN.
1. Type the show aaa command to ensure that
the authentication rules on the WSS allow
the client to authenticate. (See “Displaying
the AAA configuration” (page 548).)
2. Check the authorization rules in the
switch’s local database (show aaa) or on
the RADIUS servers to ensure the client is
authorized to join a VLAN that is
configured on at least one of the WSSs in
the Mobility Domain. (See “Assigning
authorization attributes” (page 522).)
• If the client and switch
configurations are correct,
a VLAN might be
disconnected. A client
connected to a
disconnected VLAN is
unable to access the
network.
1. Type the show vlan config command to
check the status of each VLAN.
2. If a VLAN is disconnected (VLAN state is
Down), check the network cables for the
VLAN’s ports. At least one of the ports in a
VLAN must have a physical link to the
network for the VLAN to be connected.
