alright soo ive read on ciscos page that the firmware can be reloaded but just renamed as c1200-k9w7-tar.default ... thatss fine i got software i just cant get it to seem to get to the access point , im not using telnet only differnt windows tftp programs , it will say peer 10.0.0.1 asking for default file after i let go of the mode button when center light turns color .but ill get error saying blocked or cannot overright or file invalid . right now im using 3com daemon tftp and windows xp all firewall off .i have access point plugged into router dhcp. i just need to know exaclty what to put in tftp program , asks me for remote file , local file ,tftp server ip.. i cannot see this access point anywhere through pc , router, except for when i let go of that mode button after 30 secondss thats the only time i see it come alive.

if this helps . this pc ip 192.168.1.3 access point was 10.0.0.1 have c1200-k9w7-tar.default in c:/cisco/ i have n netgear router now , any specific settings? firmware screwed no web access to access point

In order to use MODE button recovery of image, the PC that is running the TFTP server needs to be on the same subnet as the access point - i.e. it cannot have IP address 192.168.1.3

The AP should assign itself a default IP address of 10.0.0.1 so manual configured the PC to have IP address 10.0.0.2

Suggest connecting the AP directly to PC using a crossover cable.

Default IP Address Behavior When you connect a 1200 series access point running Cisco IOS Release

12.3(2)JA or later software with a default configuration to your LAN, the access point requests an IP address from your DHCP server and, if it does not receive an IP address, continues to send requests indefinitely.

When you connect a 1200 series access point running Cisco IOS Release

12.2(15)JA or earlier software with a default configuration to your LAN, the access point requests an IP address from your DHCP server and, if it does not receive an IP address, the access point assigns a default IP address of 10.0.0.1

Reloading the Access Point Image

Using the MODE button

You can use the MODE button on the access point to reload the access point image file from an active Trivial File Transfer Protocol (TFTP) server on your network or on a PC connected to the access point Ethernet port.

--------------------------------------------------------------------------------

Note If your access point experiences a firmware failure or a corrupt firmware image,

indicated by three red LEDs, you must reload the image from a connected TFTP server.

--------------------------------------------------------------------------------

Note This process resets all configuration settings to factory defaults, including passwords, WEP keys, the access point IP address, and SSIDs.

--------------------------------------------------------------------------------

Follow the steps below to reload the access point image file:

--------------------------------------------------------------------------------

Step 1 The PC you intend to use must be configured with a static IP address in the same subnet as the access point.

Step 2 Place a copy of the access point image file (such as c1200-k9w7- tar.123-8.JA.tar) into the TFTP server folder on your PC. For additional information, refer to the "Obtaining the Access Point Image File" and "Obtaining the TFTP Server Software" sections.

Step 3 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default.

Step 4 Activate the TFTP server.

Step 5 Connect the PC to the access point power injector using a Category 5 (CAT5) Ethernet cable.

Step 6 Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the access point.

Step 7 Press and hold the MODE button while you reconnect power to the access point.

Step 8 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the MODE button.

Step 9 Wait until the access point reboots as indicated by all LEDs turning green followed by the status LED blinking green.

Step 10 After the access point reboots, you must reconfigure the access point by using the Web interface, the Telnet interface, or Cisco IOS commands.
