Recovering an Isolated Mesh AP
To perform these procedures, you will need:
A notebook computer with wireless capability. If you are running Windows XP on the computer,
make sure that either the WPA2 patch or Service Pack 3 is installed.
The last known mesh configuration for the AP (steps for obtaining this information are provided
below).
An SSH client, such as PuTTY or OpenSSH.
Step 1: Obtain the AP's Last Known Mesh Configuration
1.
From the Browser-Based Configuration Pages, select Monitor> Access Points.
2.
Under Currently Managed APs, look for the status message Isolated Mesh AP (Config error), and then
click the Recover icon on the same row. A page appears, which shows the AP's last known mesh
configuration. Mesh information that appears on this page includes:
AP's MAC Address
Last Known Mesh SSID (mesh name)
Last Known Mesh PSK (mesh passphrase)
3.
Write down these details on a piece of paper. You will need them later in the next procedure.
Step 2: Set Up Your Computer for Wireless Connection to the AP
1.
Assign the following static IP address settings to your computer:
IP Address: 192.168.54.34
Mask: 255.255.255.252
2.
Create a wireless network from your computer. If you are running Windows XP, you can use the Wireless
Network Setup Wizard to create the wireless network. Configure the wireless network with the following
settings:
Association mode: WPA2
Encryption method: AES
SSID: Type the AP's last known SSID (which you obtained in the previous section)
PSK: Type the AP's last known PSK (which you obtained in the previous section)
Step 3: Connect to the AP and Update its ESSID and Passphrase
1.
After you create the wireless network, position the computer close enough to the AP to allow association.
2.
After your computer has associated with the AP, start the SSH client, and then connect to 192.168.54.33
(the AP's IP address).
3.
Log into the AP via SSH using the same user name and password that you use to log into the Browser-
Based Configuration Pages.
4.
Enter the command set meshcfg ssid “current_ssid”, where current_ssid is the SSID that the mesh
network is currently using.
5.
Enter the command set meshcfg passphrase “current_passphrase”, where current_passphrase is the
passphrase or PSK that the mesh network is currently using.
6.
Close the SSH client.
You have completed recovering the isolated mesh AP. You should be able to manage this AP again shortly.
Please wait at least 15 minutes (to allow the mesh network to stabilize), and then try managing this AP again
via the NXA-WAPZD1000.
