[SOLVED]Wifi almost instantly dropping out after successful connection

Question

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?

Answer 1

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.
