Brand new Nano v6, wlan1 dies after 2-10 min, requires unplugging


Recommended Posts

Okay, so I just got this. I'm familiar with how it works, but I'm having an issue with wlan1 dying after using it for a while. I've tried soft-resets, hard-resets. I've tried testing and making sure that no additional plugins/modules were installed and I can replicate the issue every time. The dmesg log has nothing of interest, no errors, just... 'usual business'. 

I've seen a bunch of other users in here having similar issues, but let me show what I've done and what I've discovered so far. Hopefully someone can give me some direction other than "It's broken" because I have a hard time believing that so many units could be shipped with the same issue. 

1 - I'm on software 1.1.1
2 - I'm running Zorin 11 linux (Based on Ubuntu 15.10)
3 - I did the things mentioned above (One of the symptoms was having the recon searches coming back with no results, or moving to 100% and never updating past that)
4 - Once I figured out that the hardware seems to be dying, I decided to SSH into it and manually start scanning using airodump-ng. I SSH'd into the Nano, put wlan1 into monitor mode (airmon-ng) and started scanning for networks. This worked fine initially. After monitoring a network for a while, maybe 2-10 minutes, airodump-ng stops giving results. As soon as this happens, I can take wlan1 out of monitor mode and put it back into monitor mode, but still the same problem of no clients found. (Just a blank page)
5 - I tried soft-resetting it, no luck. The only way I've found to get it to come back is to hard reset or unplug from USB

It 'feels' intuitively to me as though the wifi chip is overheating, though I have no good evidence to support what I'm suggesting. That's just kind of how it's behaving. I really want to say it's a firmware problem, but the fact that nothing changes and it just suddenly stops monitoring data packets leads me to believe otherwise. 

I can provide any logs needed, screenshots, more detailed steps, I can do troubleshooting... I'm pretty handy with the terminal for the most part, just let me know something I might have missed.

Okay, I've found something that might be of interest. 
Immediately after enabling the PineAP (associations, probes, etc) I get this output from the ifconfig: 
 

wlan1mon  Link encap:UNSPEC  HWaddr 00-C0-CA-90-A9-27-00-44-00-00-00-00-00-00-00-00

          collisions:0 txqueuelen:1000
          RX bytes:3518961 (3.3 MiB)  TX bytes:0 (0.0 B)

Something is very wrong with the HWaddr and Link encap. 

Here's the output from dmesg which was no different before when it worked and after it stopped:

[   83.640000] br-lan: port 1(eth0) entered forwarding state
[  216.460000] device wlan1mon entered promiscuous mode
 

All of this was immediately after hard-resetting, configuring and then immediately checking the wlan1mon mode. It was just fine until I enabled the PineAP stuff.

Please, use the [ spoiler ] [ /spoiler ] (Without spaces) tags when posting long logs.

The "issue" with the HWAddr and Link Encap isn't an indication of any issue at all, it is normal to see such output, because its a monitor interface. Disable wlan1mon and run ifconfig and you will see it return to a more normal output.

I tried to go back and edit it, I just didn't see any obvious way to do that. Sorry about the long post. 

Funny enough, that's not quite what happened. When I turned off wlan1mon, it stayed as wlan1mon with the same info, and the interface is still 'broken'

There's another thread where someone mentioned that theirs started showing only 1 bssid at a time, and then eventually stopped outputting altogether. I think I have it narrowed down - When I enable all 6 options under the PineAP tab. I can enable 5, and things are okay. As soon as I enable the 6th one, within a few seconds all hell breaks loose. I don't know if it's just coincidence, but I'm going to test more when I have more time and see if I can repro the issue more specifically.

Unless the device is rebooting when it's warm, or is melting the chassis, it is probably doing okay temperature wise. The CPU% indicator in the UI is "inflated" because the call to get the CPU% generates usages itself. Use top to get a more accurate reading.

Thank You! Real data is REAL! If you subtract the Idle% The true CPU usage is shown. With just the Pine AP running it's peaking at around 35%. This sure is a cool little tool!

I'm getting much the same stuff happening on my Nano, haven't had a lot of chance to look into it yet though. It seems random as to how long before wlan1 fails, sometimes it is quick(2-3 minutes), and I've had it run as long as 15-20 minutes in continuous recon with associations allowed.

 

Generally run it through my phone via the management AP, but a hard reboot always brings it right back up(though that's a bit annoying, especially if it happens after 2-3 minutes).
