Edimax USB Wireless device strange behaviour.

[Axolotl9250]

Hi, I've been trying to use the Edimax EW-7811Un nano wireless adapter in Arch. To my understanding this chipset should be supported in the current linux kernel. According to wireless compatibility lists it is of chipset 8192cu and I've seen some threads (they date back some time so I don't know the current situation) say they install another driver. I've tried to get it working out of the box so to speak:

iwconfig shows the interface.
$this->bbcode_second_pass_code('', 'ip link set wlan0 up')
I get no errors and the blue indication light flashes on once and then stops (on raspbian it's always flashing on and off, indicating it's active).
$this->bbcode_second_pass_code('', 'iwlist wlan0 scanning')
Results in detection of my home wireless, strangely the below returns and error:
$this->bbcode_second_pass_code('', 'iw dev wlan0 scan') the error says n180211 not found.
If I make a profile for my wifi network with a template file from netcfg and make netcfg connect the following happens:
$this->bbcode_second_pass_quote('', ':'): Network Up [BUSY]
n180211: 'n180211' generic netlink not found
Failed to initialize driver 'n180211'
rfkill: Cannot open RFKILL control device
ioctl[SIOCSIWAP]: Operation not permitted.
[DONE]

Hi all, I've been playing about some more and I'm beginning to wonder if actually I'm trying to solve a problem which does not exist, since if I use commands modprobe 8192cu it passes fine, no errors, and if I rmmod 8192cu and then unplug my device and plug it back in and look at dmesg, I see it picks up the device, saying at the end "registered new interface driver rtl8192cu. So it appears I don't need to do anything?

I've seen threads in the past saying one day the drivers will be in the kernel, so perhaps that "one day" has passed? I used to use linux but haven't for a about a year and a half so I'm never sure what has happened since the time people wrote these threads for pi and wireless. My keyboard was doing the phantom stroking thing even with the wireless dongle off, albeit not as often so maybe it's the keyboard. I have two wireless keyboards (different makes and models) and the other one has always been fine.

Still none the wiser about the error messages when starting up the network though. Does anybody know what they mean?

Best,
Ben.

Yes, sorry, module is supplied with kernel
I think wext and n180211 are used by default, there is a way of just saying wext to stop messages, can't remember, but it's harmless I believe

Hi, I've been searching some more and it seems the error about netlink is because netcfg uses netlink which is not supported by all devices, if it can't set up with netlink it falls back and uses wireless extensions, so it's nothing serious. I'm searching now for the remaining meanings of the remaining error messages.

[EDIT] It appears that the whole series of errors are because of the netlink / wext issue. So I think it's all harmless, unless someone knows otherwise or knows one of them does really require action.
