• Before reporting problems with your board running Armbian, check the following:

    • 1. Check power supply, check SD card and check other people experiences

      Power supply issues are one of the three biggest issues you'll face when starting with Single Board Computers (SBCs). SD card issues, whether fake or faulty, are another and issues resulting from poor board design is the other common issues you can encounter.   Power supply issues can be tricky. You might have a noisy power supply that works with one board because it has extra filtering, but won't work with another. Or you're using that cheap phone charger because your board has a microUSB connector, and it is either erratic, or doesn't start up, or even becomes the cause of some SD card issues.    Some tips to avoid the most common causes of problems reported:   Don't power via micro USB  - unless you have optimised your setup for low power requirements. Micro USB is great for mobile phones because they are simply charging a battery. It's bad for SBCs. Yes, it does work for a lot of people, but it also causes more problems and headaches over time than it is worth, unless you know exactly what you are doing. If you have a barrel jack power connector on your SBC, use it instead! If there is an option for powering via header connections, use that option!
        Don't use mobile phone chargers. They might be convenient and cheap, but this is because they are meant for charging phones, not powering your SBC which has particular power requirements.
        When you are evaluating a power supply, make sure you run some stress tests on your system to ensure that it will not cause issues down the path.   (Micro) SD card issues can be sneaky. They might appear right at the start causing strange boot and login errors, or they might cause problems over time. It is best to run a test on any new SD card you use, to ensure that it really is what it is, and to ensure that isn't faulty. Armbian provides you a simple way to do this   --   armbianmonitor -c /path/to/device/to/test  

    • 2. Make sure to collect and provide all necessary information

      We can only help if you provide quality information for us to work with. All stable images from the download section are tested, most stable upgrades are tested and we have tens of thousands of users. Even with regular and extensive testings, bugs sometimes do slip through. This is a voluntary support service and is unrelated to board makers, and is not obligated to provide you any answers. Repeated asking the same questions because you're not happy with the answers will result in you being ignored.

      Before you post a question, use the forum search as someone else might have already had the same problem and resolved it. And make sure you've read the Armbian documentation. If you still haven't found an answer, make sure you include the following in your post:   1. Logs when you can boot the board: armbianmonitor -u (paste URL to your forum post)   2. If your board does not boot, provide a log from serial console or at least make a picture, where it stops.   3. Describe the problem the best you can and provide all necessary info that we can reproduce the problem. We are not clairvoyant or mind readers. Please describe your setup as best as possible so we know what your operating environment is like.     We will not help in cases you are not using stable official Armbian builds, you have a problem with 3rd party hardware or reported problem would not be able to reproduced.

We are not clairvoyant or mind readers :P Please describe your setup as best as possible so we know what your operating environment is like.

 

1. Logs, when you can boot the board: armbianmonitor -u (paste URL to your forum post)

2. If your board does not boot, provide a log from serial console or at least make and attach a picture, where it stops.

3. Describe the problem the best you can and provide all necessary info that we can reproduce the problem.

No problem. That's why we made application armbianmonitor :)


Nothing suspicious from quick look on logs. I heard about similar network problems, but it never occurred to me. Kernel, that you use (4.9) might have still some rough edges, which manifest this way ... don't know. We need to investigate deeper and that will take some time ... Does the driver hangs or it's problem on higher level. You can try one simple trick - I assume you are using standard setup with DHCP (you don't set IP address, but it's acquired automatically). Remove content of /etc/network/interfaces and reboot.

 

Changing cables won't make any damage.

# and hassles consider using 'sudo nmtui' instead of configuring Wi-Fi settings
# manually. The below lines are only meant as an example how configuration could
# be done in an anachronistic way:
# 
#allow-hotplug wlan0
#iface wlan0 inet dhcp
#address 192.168.0.100
#netmask 255.255.255.0
#gateway 192.168.0.1
#dns-nameservers 8.8.8.8 8.8.4.4
#   wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
# Disable power saving on compatible chipsets (prevents SSH/connection dropouts over WiFi)
#wireless-mode Managed
#wireless-power off

# Local loopback
auto lo
iface lo inet loopback

This is my .interfaces

 

so delete this. and reboot.

will send after some days report if this solve the problem.

In this case network manager should kick. I assume you have our latest install? What if you start with a clean image on one spare SD card? What do you get?
