[SOLVED]Wifi almost instantly dropping out after successful connection

Hi,

I'm having an issue where my wifi connection drops about 1-2 seconds after connecting. I'm able to load 1 website in that time usually, then it drops. I was using wicd, but switched to netctl and I'm getting exactly the same issue. Wired is unaffected and works perfectly. I only have this issue with Arch, Windows seems fine.

Can anyone advise me on how best to debug this issue? Here is my 'lspci -nn' output:

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

31 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

The dhcpcd fails even though I'm successfully connected via wired connection, can I disable that if I'm using netctl?

Re: [SOLVED]Wifi almost instantly dropping out after successful connection

Don't run both netctl and dhcpd service for the same interface.  Netctl will invoke dhcpcd when it needs it.  The dhcpcd service will fight with netctl.
