Could not discover WLC using static IP. Forcing AP to use DHCP....

[EmmanuelNdoping23803]

I have a standalone system running "AP3G1-K9W8-M" with with Laptop connected (wired).

I configured a static IP on the same subnet as the Laptop. 

I keep getting the error as seen in the title and the IP resets DHCP. 

How do get around this problem. Is there a way to increase the timer so that I have enough time to upgrade to full featured appli

The 3500 is loaded with CAPWAP image and is looking for a controller.
What are you trying to do?

Hello,
I am trying to upgrade to the full featured image. When it is switches to DHCP I communication to the TFTP server is lost resulting in timeout of the download process hence the upgrade.

You could do this variant if you don't have a WLC (physical or virtual):

Hello,
I followed the instructions you provided, however the commands "tftp_init" and "ether_init".
I did however entered the tar command and got "permission denied"

Can you show the exact output please? Make sure to make no typo, or you need to type the full line again.

Use "load_helper" first before "tftp_init".
