[SOLVED] netctl wont auto-connect

Yesterday, I was playing around with e4rat and some kernel line options in GRUB to make my system boot faster. I edited /boot/grub/grub.cfg added "init=/sbin/e4rat-preload", "libahci.ignore_sss=1" and "quiet" to my kernel line as per this and this. My system boot time seemed to speed up, but after a few minutes of operation, my internet connection over eth0 would drop. I couldn't seem to find what was going on so I removed everything I added to the kernel line (save "quiet") and it seemed to fix itself. It might not have even been related as my status bar still showed a connection but I couldn't ping any websites. It could have been an issue with my university's internet. I just figured I would cover all my bases.

The real issue came when I went to connect over wifi. The profile I had been using had worked until then, but all of a sudden it didn't auto-connect. I then removed "quiet" from my kernel parameters and saw that netctl-auto@wlan0.service was failing on boot. Running "sudo netctl start <profile>" gave me errors that basically said that the interface was already up so I ran "sudo ifconfig wlan0 down" followed by "sudo netctl start <profile>" and I got a connection. This did not persist over reboot though. Whenever I reboot, I have to run "sudo netctl start <profile>" in order to connect.

So far, I have checked to see if I have any profiles enabled as per the netctl wiki that would keep netctl-auto@wlan0.service from starting and I don't. That was my previous problem, but I had since disabled all my profiles in order to auto-connect. I know that without more detailed errors at this point it will be hard to help me figure out what's going on, but I won't get out of class for another hour or so. I will post more details when I get to my laptop. Until then, I hope I have been thorough enough to at least give some kind of clue.

Thanks for reading.

Edit: while I can give more detailed errors after I get my laptop, I can't test any suggestions until later today when I get back to my girlfriends house. My laptop has trouble enough trying to connect to wifi at my university which is a different issue. The wifi at my girlfriends house worked fine with netctl previously.

Edit2: Solved the problem by removing a faulty profile generated by wifi-menu. It seems the content in this post was irrelevant.

Re: [SOLVED] netctl wont auto-connect

I google'd the status errors of netctl-auto@wlan0.service and found this thread with the same error. As soon as I read it I realized that the error was coming from a faulty profile for my university's wifi generated by wifi-menu. Deleting the profile solved the issue for me as well.

Thank you, everyone, for reading. I am marking this as solved. Hopefully I gave enough info to help others who have this problem.
