NWA1123-AC HD in boot loop. Hardware or software problem ?

Guillaume_21

Hello, I've a NWA1123-AC HD Access Point. It runs firmware 6.25.
When I got it, it was already not working : no Wifi network, no Web GUI access, no IP address assigned by my DHCP server.
I connected to it via console port and saw that it was stuck in a boot loop.
I succeeded at flashing the last firmware available but the boot loop is still there.
Here is the log file of the boot, my successful flash and the boot loop after the flash.

Is it a software problem or, more problematic, a hardware problem ?

As the device is EOL, I guess I couldn't make it repaired if it's a hardware problem.

Thanks in advance for your answers.

Hi @Guillaume_21,

Given that the NWA1123-AC HD has reached its EoL, support for this product is limited. We recommend trying to resolve the issue by performing a factory reset. If the problem persists after the reset, we suggest considering our newer access point solutions to ensure the security and performance of your network.
