In my last post we looked at how to fix the corrupted IOS in a Cisco 1250 Wireless Access Point, the other way of recovering the corrupted IOS is by again by using a solar winds TFTP server, but in this procedure the access point loads itself the image file from the TFTP server. In order do so follow the below mentioned steps.

Step 1

Configure the PC with Solar Winds TFTP server with a class A Static IP Address range of 10.0.0.2 to 10.0.0.30.

Step 2

Make sure that the PC with the solar winds TFTF server contains the Cisco 1250 Wireless Access Point IOS image file (such as c1250-k9w7-tar.124-21a.JA1 in the Solar Winds TFTP server folder) and the TFTP server is activated.

Step 3

Rename the Cisco 1250 Wireless Access Point IOS image file in the solar winds TFTP server folder to the default image name –c1250-k9w7-tar.default for a Cisco 1250 Wireless Access Point.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Step 4

Connect the PC with solar winds TFTF server to the Cisco 1250 Access point with a  Category 6or Cat5 Ethernet cable (straight cable).

 

 

Step 5

Disconnect power from the Cisco 1250 Access point.

Step 6

Press and hold the MODE button while you reconnect power to the Cisco 1250 Access point.

Step 7

 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the MODE button until the console indicates

Button is pressed; wait for button to be released

Once you release the button you will see the Cisco 1250 Access Point starts downloading the default IOS image from Solar wind TFTP sever as shown below

 

Step 8

Wait until the Cisco 1250 access point reboots as indicated by all LEDs turning green followed by the Status LED blinking green.

Step 9

After the Cisco 1250 access point reboots, reconfigure the access point using the Command Line Interface (CLI) or GUI.
