You are the best and my hero

Its Working like a charm

Thank you so much.

This long post it´s a good "How To"

MrEngman

Hi aabento, You need to update the driver. You can do this by running the following commands wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20130830.tar.gz tar -zxvf 8188eu-20130830.tar.gz sudo install -p -m 644 8188eu.ko /lib/modules/3.6.11+/kernel/drivers/net/wireless sudo insmod /lib/mo...

Hi MrEngman, My Wifi adapter is connected directly to the Raspberry Pi. I connect my Pi to a USB charger supplying 5.1V which I have been using so far without any problem. However, my Raspberry Pi previously connects to the internet with another USB adapter, could that be a problem? Settings conflic...

Hi jiangchen, I'm really not sure why you are having problems. To make sure the instructions are OK I have just tried a new raspbian SD card and set up the wifi using my instructions to load the driver and the Wifi Config GUI to connect the wifi and it set up correctly first time. This was on a old ...

Hi Dutch_Master,

I manage to key in the code using root access and I can see that the /etc/modules file has the 8188eu driver name within it.

However, once I restart the Raspberry Pi, the driver still does not load....

I wonder what is the problem.

Thanks for your help so far.

Dutch_Master

I assumed you're running a standard Raspbian install and thus was working as the pi user. If you've obtained root access some other way, drop the sudo prefix: echo "8188eu" >> /etc/modules Alternatively, use nano to open the /etc/modules file and add the name of the driver on a new line. Save the fi...

Hi Dutch_Master,

Thanks for the suggestion, however,

I get a permission denied after using this code:

sudo echo "8188eu" >> /etc/modules

Dutch_Master

Add the name of the driver to the file /etc/modules to make it persistently loaded by the kernel at boot. This is the easiest way: sudo echo "8188eu" >> /etc/modules Mind, the command requires 2 arrows, not a single one (you'll overwrite the existing file, bad idea) or more then 2 (dunno what'll hap...

Hi MrEngman, I redo all the steps again, this time it seems when I start the wpa_gui it does not notify me of disconnection again. Maybe it is because I am testing it my Pi headless connecting to my laptop and sharing my laptop wifi. After the installation I run lsmod, the module is listed there. Ho...

MrEngman

OK, driver is loaded, the scan shows you have a Wifi network available, but it also shows that encryption is on. Log in to your router and switch the encryption off (for now). Try to connect again. However, the scan also shows you need to use channel 6 (out of 11), so you may want to check your ada...
