Hello.
I have a PC Engines Alix 2 board with a mini pci wifi adapter:
Model: WLM54GP23ESD; FCC ID: TK4-WLM54GP23ESD (Atheros)

I flashed the pre built /chaos_calmer/15.05.1/x86/generic/openwrt-15.05.1-x86-generic-combined-ext4.img image.
It boots and I can access it via LuCi and SSH, but WiFi does not seem to work. Running the ifconfig command does not show a wlan0 interface. I already installed some drivers with opkg which were listed in the wireless wiki page (ath5k, ...), but no success.
Is my wifi card unsupported?

bump

Probably worth stating the drivers you loaded, your config files and relevant log entries.

That said if you look on the PC-Engines site they basically offer compex and wistron cards. 
https://www.pcengines.ch/newshop.php?c=4

The old product list contains, I think, all the items they offered which does not seem to include this card.
https://www.pcengines.ch/product.htm

I had discussions with them a couple years back on this and seem to recall them suggesting Compex, but do not recall the item number.  Also be aware that if you read the card info it says they are dual band, but what that really means is they can do either band, but not both bands simultaneously.

I found using a separate AP just works better and easier to locate in a good location.

Compex worth a try. I use Compex on APU2 running openwrt. And used Compex on ALIX runing voyage.

Thanks for your replies.
The hardware previously was used with fli4l which is also a router firmware similar to OpenWRT.
With the fli4l software the wifi card worked, so I do not think it is a incompatibility between the board and the mini pci card...
fli4l is also linux based, so linux drivers for the wifi card should be available?
The reason I want to switch to OpenWRT is that it seems more flexible configuration wise (in fli4l you have to choose your packages at build time).
I used the package manager to install the following packages: kmod-ath9k, kmod-ath5k, kmod-b43, kmod-mac80211, kmod-cfg80211, wireless-tools

Which log files should I post and where can I find them?

First you need to be sure the PCI bus is working.  The bus itself requires a kernel driver. 

Install pcitools and use lspci to see if your card is found on the PCI bus.  Then look at the wifi driver.  This should be an ath5k card.  IN that case, you will not need ath9k (Atheros n cards) or b43 (Broadcom).

I removed the other drivers and only kept kmod-ath5k and regenerated the config but still no wlan0 when running the ifconfig command...

Is installed the generic x86 image, would the geode image be better / more suitable?

Check dmesg for any ath5k related messages.  Run iw list to see if any wifi device exists.

//edit:
Just did a clean flash with the x86 geode pre-built image, enabled wifi over LuCi, and now wifi works! Dont know if it is because of the different image or I just messed up my config somehow before...
Thanks for your help
