Hi harris,

The AP that you are using is the LWAPP AP (LAP1242) this requires WLC.. this will not work without the WLC.. do you have one?? if you doner have one. then this behavious is expected.. the AP will be in reboot loop till it registers to the WLC.. and LWAPP == no Web access.. only Autonomous AP has the GUI access.. i request you to convert the AP using the below command..

1>> Download the Autonomous image from cisco.com

2>> connect the console cable between the PC running tftpd32 server and the AP.

3>> Point the image in the TFTPd32 server and then make sure you have the connectivity to the AP from the laptop (same subnet ip)..

here is the steps.

AP> en

AP# debug lwapp console cli

AP#conf t

AP(config)#int fa 0

AP(config-if)#ip address 10.0.0.1 255.255.255.0

AP(config-if)#no shut

AP(config-if)#end

on the laptop fa interface give 10.0.0.2 /24 and try pinging 10.0.0.1 (you should be able to)

then issue the command

AP#archive download-sw /force-reload /overwrite tftp://10.0.0.2/

eg..

archive download-sw /force-reload /overwrite tftp://10.0.0.2/c1240-k9w7-tar.124-21a.JY.tar

this will do it.. i mean stopping the logs on the switch and also getting the WEB access..

lemme know how this answered your question..

Hi Harris,

issue show version on the AP.. if the image says rcvrW8 then its LWAPP, if its W7 then its autonomous.. or even easy one is..

get into AP cli and issuew the command

en

conf t

if you ge ta invalid command then its in LWAPP if it goes to config mode then its in autonomous mode..

lemme know how this answered your question.. if its in LWAPP thne my first post will help you to resolve the issue.

Which interface?  Ethernet or Radio?

Have you checked the cable?
