Not sure what can I omit from here using the image builder )
The history: (just for whining)
A friend flashed it for me (can't remember the version, but he did it like 1-3 months ago, seems like it was 17), then I've found out that it doesn't save the config and boots into default config including passwordless root login on all interfaces.
So, I've flashed 15.05.1, since it was on the OpenWRT wiki for the device a month ago (I was lost in architectures and download links and didn't want to risk bricking the router). The config survived reboot, but I've just installed a fresh xubuntu 18.04.1 onto my laptop and it was working ok for half an hour and then started losing connection once per minute both through wifi and ethernet, also lost the connection on eth so it couldn't even get an ip. I thought it could be because of an old firmware. (Seems like it was not the firmware, because it still doesn't connect and the windows box works ok, so did the ipad and iphone/androids)
I've watched the logs on the router and detected that it was sending dhcp handshakes to the laptop. Nevertheless I decided to upgrade the firmware and flashed the new 18.06.1 (the new link is in the wiki today).
