Believe me, I have searched the forums here, and tried a lot of stuff!

apt-get update and apt-get upgrade did improve things a bit, as now it appears that a driver is being loaded, I see this in dmesg:

Code: Select all

[   18.489644] usbcore: registered new interface driver rtl8192cu

I downloaded and ran the install-rtl8188cus-latest.sh script, and got the following:

Code: Select all

Press any key to continue... 

An RTL8188CUS driver module is installed and loaded.

You have 1 wifi adapter configured.
wlan0 is configured but is not installed.

The Pi has an internet connection.

Any files needed for the installation/upgrade will be downloaded from the
Internet unless they have already been copied to the SD card /boot directory.


Unrecognised software version: Linux raspberrypi 3.6.11+ #446 PREEMPT Fri May 10 20:17:25 BST 2013 armv6l GNU/Linux

Downloading the latest script.

The script you're using is the latest version.

Aborting the rtl8188cus installation script.

It looks like "wlan0 is configured but not installed" might be a clue, but I have no idea how to address that.

Any help would be greatly appreciated!

The wifi configuration on the standard Raspdian desktop should work. You don't need any script to install a driver for it.

Apparently, something I did prior to attempting to get wifi working had hosed things.

I tried again with a fresh OS image, and things worked much better. The wifi dongle was recognized at boot time, and wlan0 appeared in the WiFi Config applet.

So... it worked with a clean OS image, but apt-get update and apt-get dist-upgrade broke it.

No wifi interface available, no module loaded.

Don't judge Linux by the Pi.......

I don't. I have been a Linux user for years, and a user of various *nix before that. Like when it was impressive that you could send an email and get a response the same day.

Raspbian is the most challenging I have encountered.

I used details at http://wiki.debian.org/WiFi/HowToUse#Command_Line point 3, and making wifi work on pi is not pi specific problem, it is really a linux configuration problem (or task)

I never installed any driver in my default whizzy image and it worked like charm.

#lsusb
showed
Bus 001 Device 004: ID 0846:9041 NetGear, Inc. WNA1000M 802.11bgn [Realtek RTL8188CUS]

Most probably

I used netgear WNA1000M adapter and now it is working great.

Scan for available networks and get network details:

$ su
# iwlist scan

If you lan card is working it will show the available network

Now edit /etc/network/interfaces

it should already have entries like
----------------------------------------------
auto lo
iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
----------------------------------------------

now login to gui and use wifi manager to put in setting (using gui will really make your life easy)

what it do is internally update wpa_supplicant.conf (to make your life easy)

--
after this your wifi should work. (if blue light on your wifi is blinking most probably it is working)

I'm sure it did.

The problem was indeed RPi specific. A version of the kernel was released which included a version of the driver that did not recognize the WNA-1000M. As long as you weren't using such a kernel, it would indeed just be a matter of linux configuration for the adapter.
