  • this is what i get when i run journalctl pastebin.com/RSzmB5U9 Nov 14, 2015 at 15:45
  • You should either paste the entire log or use the end -e flag journalctl -e when it happens Nov 14, 2015 at 15:48
  • sorry, this is the output of journalctl -e while the error appears pastebin.com/dpKGXNfh im trying to check with half duplex and if there is proper compatibility with the NIC on 15.10 Nov 14, 2015 at 16:48
  • a friend cleared it out: lspci -v says i have a realtek rtl8723be so i just need to * create /etc/modprobe.d/rtl8723be.conf file and edit it to this line: * options rtl8723be fwlps=0 Nov 14, 2015 at 22:28
