[Losing connection to Pineapple after short period of time]

What are the chances for this to be a software problem? Are there any other logs that I can collect?

[Losing connection to Pineapple after short period of time]

It happens even if I don't install any infusions and just connect to the AP and start browsing.

I think that if I start using karma or sslstrip I just got disconnected faster but I am not very sure if this is always the case.

[Losing connection to Pineapple after short period of time]

I have a brand new Pineapple Mark V purchased from Hakshop and I can't use it for more that 5-6 minutes. It boots normally, the web interface is available, I can ssh into it but after a few minutes it becomes inaccessible. I cannot ping it (172.16.42.1) and the AP is gone. It is like something happens with the network devices on the pineapple because the amber led goes off for about 6-7 seconds and when it comes back I cannot access it anymore. I am using an AC adapter, not batteries.

I have tried versions 1.2, 1.3 and 1.4 of the firmware and I get the same behavior with all of them. I bought a new SD card (SanDisk class10 8GB) and still no luck. I am out of ideas how to debug this thing.

These are the syslog messages and dmesg that I capture before I get disconnected:

Any ideas what else I can try? Any help is much appreciated.
