Hello,
Today I’ve played with Antergos live USB for about 15 minutes. Everything was working great so I just followed with installation.
After installing the system I’ve noticed that my internet connection became incredibly slow:
speedtest
I don’t know why is that, as I said when running from USB stict everything was just fine.

  • I don’t know what info I can provide to give you more information about the problem, I look forward to any guidelines
  • On login, I’ve encountered warning notification saying “cannot get IP configuration”
  • Downloading packages at installation was fast as usual
  • Connection is very slow even in local network (visiting my router we interface for example)

Pinging my router:

$ ping 192.168.8.1
