Unable to bind wifi dongle to WPA2-PSK. Help pls

[rjalex]

Dear friends,
I hope not to bother you all too much, I'm just starting with Archlinux via a small but nifty "distro" called Archphile to drive a USB DAC off a Raspberry and I am almost good with the setup SAVE for the necessity of connecting via a wifi dongle.
The dongle is an Edimax Wireless 802.11b/g/n nano USB adapter part no. EW-7811Un which should connect to my FritzBox 7390 Wifi router running an 802.11n 2.4GHz network with WPA2-PSK (CCMP) authentication.
Here is what I tried to do to debug the situation but I am stuck.

Any further help please ?
My plan is after I fix the connection manually I'll setup the proper netctl file to automate.
Thank a LOT in advance

Thank you so much for attempting to help me ! I am 100% so far.

Pls bear with my ignorance but I promise to learn fast.

So you're saying that despite the dongle being recognized by some device driver already present in Archphile's kernel it's probably not working well and you suggest compiling a better one ? Did I get this right ?

Is there a dummy proof tutorial on how to go about downloading the BUILDPKG you mention, build it and use it on my Archphile which is a streamlined "distro" with minimal stuff to support hifi music ?

Ciao from Rome

You might want to check with those that make Archphile for their driver support. Depends on what they built in.

Yep I think it's the better path until I become more expert ! Thanks again very much.

Ok my friends,
I'm still stuck despite a GREAT help from Archphile developer. He prepared for me a package with the module and here's my current situation:
root@archphile ~]# dmesg | grep usbcore -> 12.897157] usbcore: registered new interface driver rtl8192cu (and no other reference to rtl8192cu in dmesg)

[root@archphile ~]# ip link -> 5: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 80:1f:02:f7:3a:71 brd ff:ff:ff:ff:ff:ff

[root@archphile ~]# ip link set wlan0 up -> 5: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000

[root@archphile ~]# iw dev wlan0 link
Not connected.

AND HERE is the step from the archlinux wiki where things start to go wrong:

[root@archphile ~]# iw dev wlan0 scan
command failed: No such device (-19)

Do I need to load any proprietary firmware ??? If so how ?

Thanks a lot
