## Manually Update the Access Point Configuration

You can manually update the configuration of an Intel® PRO/Wireless 2011B LAN Access Point by editing a text-based configuration file and transferring that file to the access point. Use one of the following options to transfer the file:

- Telnet to the access point from a TFTP host computer using an Ethernet connection.
- Transfer the file with Xmodem file transfer protocol from a computer using a null modem serial cable.

| NOTE: Xmodem transfers require more time than TFTP transfers.

Before you update the access point, edit the AP_CFG.TXT file to match your site-specific network settings. You can use any text-based editor to change the file; for example, Notepad in Microsoft Windows*.

### Updating Configuration with TFTP

The Ethernet TFTP update method requires a connection between the access point and a computer on the same Ethernet segment. Make sure the computer has a TFTP server running on it. Running the server requires third-party software like NetManage, Inc. PC/TCP* for DOS or OnNet* for Windows*. The wireless TFTP update method requires a connection between the access point and a TFTP server. The TFTP server can be running on a computer connected to the network though a wireless network card.

To update the access point configuration

1. Copy the configuration file AP_CFG.TXT to the terminal or computer hard disk.
2. Telnet to the access point using its IP address.
3. At the prompt enter the password. The default password is Intel (the password is case-sensitive). The access point displays the Main Menu.
4. Select Special Functions from the Main Menu and press ENTER.
5. Press F3 to view the Special Functions update page.
6. Select Alter Filename(s)/HELP URL/TFTP Server and press ENTER.
7. Type the configuration file name in the Config. Filename field. Change this only if the network administrator requires a new file name. The default is AP_CFG.TXT. Verify the accuracy of the file name path (see step 1).
8. Type the TFTP Server IP address or name in the TFTP Server field.
9. Press F1 to save settings, and then type Y to confirm.

| CAUTION: Do not use the Use XMODEM to Update Access Point's Firmware option on the access point's Telnet menu. This option causes the access point to reset and look for the configuration file over the serial interface.

10. Under the function heading Use TFTP to Update Access Points , select Config .
11. Press ENTER and then type Y to confirm. This ends the Telnet session.

> Note that the Wired LAN Activity light on the access point does NOT flash during the transfer. To view the file transfer log, switch to the TFTP application. The access point resets when the file transfer completes.

To verify that the network settings are correct

1. Telnet to the access point using its IP address.
2. At the prompt enter the password. The default password is Intel (the password is case-sensitive). The access point displays the Main Menu.
3. View the network settings on the System Summary screen.
4. Press CTRL+D to end the Telnet session.

### Updating Configuration with Xmodem

The Xmodem upgrade method requires a direct connection between the access point and a computer using a null modem serial cable and using software like HyperTerminal* for Windows* 98.

Before you update the access point:

- Copy the configuration file AP_CFG.TXT to the hard disk of the computer that you will use to transfer the file to the access point.
- Attach a null modem serial cable from the access point to the computer serial port.

The following instructions describe how to use HyperTerminal* on a computer running Windows*.

To update the access point configuration

1. On the computer connected to the access point, start the HyperTerminal* communication program.
2. Type a name for the session, and then click OK .
3. Select the correct communication port and set the following parameters:

emulation | ANSI
bits per second | 19200
data bits | 8
stop bits | 1
parity | none
flow control | none

4. Click OK and press ENTER to display the access point Main Menu .
5. Select Enter Admin Mode and enter the password. The default password is Intel (the password is case-sensitive).
6. Select Special Functions from Main Menu.
7. Press F3 to view the Special Functions update page.
8. Under Use XMODEM to Update Access Points , select Config .
9. Press ENTER, and then type Y to confirm downloading the file AP_CFG.TXT.

| CAUTION: Make sure the file is correct before sending. An incorrect file can render the access point inoperable.

10. On the HyperTerminal Transfer menu, click Send File.
11. Click Browse and locate the file AP_CFG.TXT.
12. Select the XModem protocol from the drop-down list.
13. Click Send.

Hyper Terminal displays a progress bar during the transfer process. The download is complete when the terminal screen displays:

>     Download Successful
>     Updating AP
>     Set Successful

If the transfer fails, the access point displays an error message indicating the cause.

The access point automatically resets after the file transfer completes. Exit the communication program to terminate the session.
