I recently purchased a dream plug
Where from ? If not from NewIT knowing the serial number helps...(search this forum for why)
What Distro are you running (from internal u-SDHC or external SDHC)
What do you want to use the plug for (Squeezebox Server, Firewall\Router, etc) to what (Laptop running XP, Windows 7 PC, etc)
Which instructions did you follow to set up AP mode ?
I suggest you search this forum and plugcomputer.org for past issues with Wifi, you will then know what to try and what to look for.
Follow one of the available guides, when you hit difficulties post again (linking to the guide you used so we can see what you have tried to do) with any specific error message you got.
From what you have posted I can see your kernel is trying to load both AP Mode and Client Mode drivers at the same time, start by blacklisting the relevant modules.
