Are you sure this is a netctl specific issue or just a wifi issue?

Have you tried using other network managers and witnessed the same effect?

I used to use Network Manager a *very* long time ago and didn't notice an issue. Then I used netcfg and didn't have this problem until I switched to systemd. I looked into the issue a bit and concluded that the network managing application has to disconnect from the network prior to suspending and reconnect to the network after resuming the system. Neither netcfg nor netctl do this in systemd.

I've managed to create a temporarily solution, it's based on https://wiki.archlinux.org/index.php/Systemd#Combined_Suspend.2Fresume_service_file - I've attached the netctl version. It stores the running profiles before suspend and stops them. After resume it restores the saved profiles. To test the file, put it in `/etc/systemd/system/` and run `systemctl enable netctl-sleep`.

What is so temporary about this solution? This was one of the intended uses for `netctl (re)store`. In fact, this is something I like to include in netctl by default.

By temporarily I meant that it's a fix for the time until it gets resolved directly in netctl. I'd be glad, if this fix got included in netctl.

Can you also write a little documentation for netctl.special.7?
