I'm having problem with the Ethernet USB adapter and Pi Zero. Adapter loses its ethernet connection for 2 or 4 seconds very ofter, sometimes many times in minute and sometimes it might take ten to twenty minutes, but anyway the connection breaks all the time. I tried the adapter also with my Ubuntu laptop and similar thing happens also with that. Pi Zero works fine with cheapest eBay ethernet-usb adapter so the problem seems to be with the adapter instead of the cable or router.
Here's a snippet of syslog which shows the problem. What should I try to do to fix the problem?
