Hi I'd like to share my little weekend project - virtual radar for airplane tracking. The radar is virtual because it doesn't use big rotating antennas, it doesn't transmit, etc - it received ADS-B broadcasts from airplanes and decodes them using cheap RTL-SDR USB dongle worth around £8 (<£10 with s...

If the card is Edimax EW-7811un, you may want to check http://www.ctrl-alt-del.cc/2012/05/rasp ... s-ada.html

uhm...8192cu != 8191su

but was worth a try - glad you got it working and thanks for the pointer to the solution

tqm

rtl8192cu is the name of the original module that comes with debian package…

The fact it loads means you didn't blacklist it first… unless blacklisted it will load before the 8192cu (from the website) and block the card because it can't use it.

tqm

Having the plaintext psk is a risky thing... but if you run it via wpa_passphrase and put result in config file exactly as wpa_passphrase returns it, it will work as well.

Glad you got it going!

tqm

Yup... and above you have exact working configuration examples for all of those options - WPA-PSK (from documentation) and WPA2-CCMP (via my blog) - sorry, can't help any more than that.

tqm

<t>Where did you get key_mgmt=WPA-PSK from? I guess from the docs… The config in my blog post works on AP that doesn"t do WPA, only WPA2. The chkmic error you get is related to one of the security checks on the packet (for simplicity let"s say it"s checksum) so you have misconfiguration s...

tqm

Did you follow the whole of my blog post?

What do you have in /etc/network/interfaces?

tqm

<t>There is no such thing in config like WPA2 or AES-CCMP… The config I gave in the post was already for WPA2 network (AES-CCMP), so DO NOT change 'WPA' to 'WPA2' - it will not work. For WPA/WPA2 with TKIP and CCMP (auto-negotiate) you should use: key_mgmt=WPA pairwi...

tqm

<t>Ok, the depmod errors are for sound stuff, not really related to wireless so I'll ignore them in this thread. iwconfig shows your wlan0 properly, the card was detected and works - now all you have to do is to connect to your network. WPA and WPA2 networks need wpa_supplicant - I hope y...

tqm

<t>First of all show me what "sudo iwconfig" shows… iwconfig is for configuring wireless interfaces (mode, frequency/channel, etc), then ifconfig to set link up/down and IP – do not confuse them. Mine says: root@raspberrypi:~# iwconfig lo no wireless extension...

tqm

<t>Mine is USB ID 7392:7811 Yes, adding the 8192cu module (binary blob) was fine to get the card running but then serious stability issues started showing up - that's what pushed me to update kernel.I've seen various threads and comments saying there is several revisions of the hardware i...

tqm

<r>firmware-realtek package doesn't seem to help at all I've dropped complete step by step description of getting 8192cu driver (binary blob mentioned above in this thread) working. Have a look at <URL url="http://www.ctrl-alt-del.cc/201.....s-ada.html">http://www.ctrl-alt-del.cc/201.......

<r>gooeygeek said: I can"t find any information about the current drain of the Edimax EW-7811Un, but using a powered hub (Belkin F5U027 7-port hub) makes no difference This is not the power drain issue – 1A psu is more than enough. Problem is with the kernel module...

tqm

<t>If you have blacklisted the original rtl8192 module you have to load the new one modprobe 8192cu or add this line 8192cu to /etc/modules and reboot to test... this will load this module regardless of hardware present or not and if hardware is there, it ...

<t>GPS + accelerometer + OBDII is more than YES YES and I hope Pi will cope with it - there's not as much data on first two, not sure about OBDII. Video is a bit harder, there's a lot of bandwidth to be served and data to save. You will run out of storage fairly quickly and in multiple wr...
