Hi tm,

You can convert AIR-LAP1121G-K-E9 to autonamus access point,pls do follow the procedur

Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:

Step 1 The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30.

Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.

Step 3 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, and c1240-k9w7-tar.default for a 1240 series access point.

Step 4

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

Step 5

Disconnect power from the access point.

Step 6

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

Step 7

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

Step 8

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

Step 9

After the access point reboots, reconfigure it using the GUI or the CLI.

Thankx&Regds
