It doesn't appear to be broken. You weren't sure about using a space in the network name (SSID). I tried with one of my access points and it appears to be OK using a space character in the name. Can you define how you "disconnected from the network". Have you checked the output of command ifconfig ...

I'm beginning to think I have a bad dongle... I tried a fresh install of wheezy, with the new wifi setup, and was able to scan for networks, and join, but I had no internet access. If I ever disconnected from the network, the scan wouldn't work again. I would have to pull the dongle out and plug it ...

Well the driver is loading OK, and from the above the 70-persistent-net.rules looks OK provided the mac address is not 00:E0:4C:xx:yy:zz. If it is delete the line. For the EW-7811Un I would expect it to be something like 80:1f:02:xx:yy:zz. So why the scan isn't working is really odd. I'm sure I've ...

OK the driver is loaded OK - lsmod shows 8192cu installed and dmesg shows registered .. rtl8192cu. if there was a problem with the driver then it wouldn't be displayed in lsmod and dmesg would show some error or other. So why doesn't the dongle start up or scan? What does the file /etc/udev/rules.d...

I tried setting up my dongle to an old windows xp desktop. I was able to see my wifi network, but unable to connect. This is a common issue that I run into with some older xp machines. The LED also started blinking, but was not blinking when plugged into my rpi.

Is your wifi dongle OK have you checked it on any other system? If you run command dmesg do you see any messages about rtl8192cu? If you run the command lsmod do you see an entry for 8192cu? This is the only mention of rtl8192cu from dmesg. [ 317.695611] usbcore: registered new interface driver rtl...

I have actually tried both ways. Initially I tried going in through the command line, (I manually made sure all the files were in the root directory that were needed, according to the instructions). Later I reformated the SD card, and ran the script from the gui. Again, the drivers were installed, b...

I've tried using the script on Xbian to set up my dongle, but I keep getting hung up when it tries to connect. During a fresh install, it will tell me to plug in the dongle, but get hung up saying "ADDRCONF(NETDEV_UP): wlan0: link is not ready" It stays at this message until I stop the process. I'm ...
