 Chapter 19 Troubleshooting

NWA1123-ACv2 User’s Guide

173

1

Make sure the wireless LAN (wireless radio) is enabled on the NWA.

2

Make sure the radio or at least one of the NWA’s radios is operating in AP mode.

3

Make sure the wireless adapter (installed on your computer) is working properly.

4

Make sure the wireless adapter (installed on your computer) is IEEE 802.11 compatible and 
supports the same wireless standard as the NWA’s active radio.

5

Make sure your computer (with a wireless adapter installed) is within the transmission range of the 
NWA.

6

Check that both the NWA and your computer are using the same wireless and wireless security 
settings.

Hackers have accessed my WEP-encrypted wireless LAN.

WEP is extremely insecure. Its encryption can be broken by an attacker, using widely-available 
software. It is strongly recommended that you use a more effective security mechanism. Use the 
strongest security mechanism that all the wireless devices in your network support. WPA2 or WPA2-
PSK is recommended.

The wireless security is not following the re-authentication timer setting I specified.

If a RADIUS server authenticates wireless stations, the re-authentication timer on the RADIUS 
server has priority. Change the RADIUS server’s configuration if you need to use a different re-
authentication timer setting.

I cannot get a certificate to import into the NWA.

1

For 

My Certificates

, you can import a certificate that matches a corresponding certification 

request that was generated by the NWA. You can also import a certificate in PKCS#12 format, 
including the certificate’s public and private keys.

2

You must remove any spaces from the certificate’s filename before you can import the certificate.

3

Any certificate that you want to import has to be in one of these file formats:

• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters, 

uppercase letters and numerals to convert a binary X.509 certificate into a printable form.

• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital 

signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The 
private key is not included. The NWA currently allows the importation of a PKS#7 file that 
contains a single certificate.
