    If you have the console cable to connect NWA1100-NH.

    Please refer to below operating procedure to do firmware recovery.

    Hi together! I have also the problem, that my NWA1100n is bricked after failed update. So I've searched for a console cable. Can you tell me which one I must use? Seriell to RJ45 or USB to RJ45 or which one?

    Hi @Ludibubi

    Your AP is NWA1100-N without NWA1100-NH, right?
    If so, NWA1100-N is a legacy AP which is not supported the console port. 

    Below is how to update the firmware via FTP method on NWA1100-N, please try to do it.

    1. PC connects to NWA1100-N and configure PC's IP in same subnet.

    2. Copy firmware to C:\ and change file name of firmware to ras with no extension.
    For example,
    100AAQ3C0.bin is changed to ras

    3. Open command window on PC to load firmware and its path moves to C:\

    3-1 ftp>NWA1100-N IP
    3-2 admin-------------------------> device username
    3-3 1234-------------------------->device password
    3-4 bin--------------------------->transmit data in binary mode
    3-5 put ras -------------> firmware filename

    Please await FW write time done.(LED SYS and WLAN both are green)

    Hi! Thanks for reply. I tried this without success. I think the problem is that the AP is bricked and so the interface is not reachable because it doesn't recognize the IP-adress and cannot answer. Any other idea?

    Hi @Ludibubi

    Please run the RMA process with local agent.
    But actually this legacy AP is EoL for a while.
    I think the warranty period should be expired too.

    What do you mean with "run process with local agent"?
