[solved] Wifi issues

bbm21 · 2013-08-24 02:05:35

I have Arch installed on my samsung series 9 ultrabook, one of the older models if that matters. I am having a few problems with wifi that I haven't been able to fix. First, I cannot connect to my family's password protected wpa2 network. I used to be be able to inconsistently, now I cannot connect to it at all. when I run 'sudo wifi-menu' and connect to the network I get this output:

"job for netctl@wlp1s0\x2dMynetworkl.service failed. See 'systemctl status netctl@wlp1s0\x2dMynetwork.service' and 'journalctl -xn' for details."

wlp1s0 is my wifi interface (like wlan0 for most people).

when I try to connect with wpa_gui it says:

"Could not get status from wpa_supplicant"

and also, I have been connecting to my neighbor's open network and it does not automatically connect on each boot, I have to manually connect with wifi-menu every time I turn on my computer

any ideas?

\x2d is an escape character representing a '-'.

It tells you to to use 'journalctl -xn' for more details… did you do that? I surely hope you have your neighbor's permission to be using his/her network. Open or not, if you don't have permission, what you are doing is likely illegal.

I did not know that about /x2d, I just updated the op. Also I do have permission to use her network, but obviously, I would rather use my own. I did run journalctl -xn and it didn't hep me much but here is the output if someone better than me wants help:

Aug 23 19:23:09 arch network[8905]: DHCP IP lease attempt failed on interface 'wlp1s0'

try increasing the DHCP timeout in your networks profile.

check out man netctl.profile if you are unsure of how to do that.

@bbm21

Make sure your stop network before you start another one. For example to disable wlp3s0.

ip link set wlp3s0 down

Is that intentional? Why not just use '-'?

WonderWoofy · 2013-08-24 04:16:47

@donniezazen, systemd considers a '-' in a unit name a representation of a '/'. So you can probably see that things from your fstab are translated to these specially named mount units. For example, the rootfs is the -.mount file (which BTW, kind of sucks since the CLI thinks you are trying to issue a flag/switch… so you have to use ./-.mount instead). So you should also have some sys filesystems that are moutned automatically by systemd. So if you do systemctl --type=mount then you will see that there is the sys-kernel-config.mount unit, which translates to /sys/kernel/config.

@WonderWoofy Thanks. I did notice that.

Sweet, that worked. Thanks for the help. Now all I need is to be able to connect on boot if that is possible.

WonderWoofy · 2013-08-24 18:50:02

So I assume that you are still using netctl… if that is the case, then enable the profile.

bbm21 · 2013-08-24 19:10:57

cool that worked too. Thank you to all of you for the help!

bbm21 · 2013-09-07 03:59:08

ok so it worked for a while, not its not again, I tried increaseing my dhcp timeout even more and that didn't work, here is my output of journal -xn this time

Try renaming the config file to something without the '-'. I know it was autogenerated this way, but systemd treats a '-' in a special way, as you can see from that journalctl output. So often times this can lead to problems… or so I have read from reports of other users.

When systemd creates the mount units, from your fstab, it replaces the path's '/' with '-'. So mounting something at /var/lib/whatever would result in var-lib-whatever.mount. That is why the unit that is trying to be started has a \x2d in place of the '-'.

Also, please learn how to use code tags and go back and fix that post above.

ok well that seems to have worked. I'll update this post again if I have further problems, thanks!
