Can you assist in the setup of a B2 as a Wireless Access Point?

I've bought a USB Wifi adapter, which seems to register:
mybubba@b2:~$ lsusb
Bus 001 Device 003: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN

I have done this:
apt-get install firmware-realtek

root@mybubba:/home/owner# lsmod

But I don't think the kernel module for the device has loaded.

How would I know the correct kernel module has loaded? Or should I be looking for some errors somewhere?

Also, my interfaces file just has the following. Do I need to add an entry for wlan0 ? Or if the correct kernel module loads, will that file be updated automatically?

root@mybubba:/home/owner# more /etc/network/interfaces
iface eth0 inet dhcp

iface eth1 inet static
address 192.168.1.10
gateway 192.168.1.1
netmask 255.255.255.0

auto lo
iface lo inet loopback


Any help on my next steps would be appreciated.

Apparently there are no Squeeze packages to support the CUS version of this chip - the SU drivers don't work. I guess you need to compile it yourself.

driver source

Thanks Gordon.

I had started to go down that road. But I am getting the following build error:

8188C_8192C_usb_linux_v4.0.2_9000.20130911# make
make ARCH=ppc CROSS_COMPILE= -C /lib/modules/2.6.39.4-13/build M=/home/owner/rtl/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911/driver/rtl8188C_8192C_usb_linux_v4.0.2_9000.20130911 modules
make: *** /lib/modules/2.6.39.4-13/build: No such file or directory. Stop.
make: *** [modules] Error 2

I do have the build essentials and kernel headers installed. Any suggestions welcome.

Are you compiling on the B2 itself? I had a similar issue with one of my first projects. The modules directory should contain a symlink to the kernel source ( build -> ../../../usr/src/linux ). Obviously this means you need to have the source and it needs to be prepared. There is a second issue here as well and that is that the source as distributed by Excito is meant to create a Debian package and adds additional symbols during that build. The result is that if you use that source to create external modules, the version stamping is off and the module won't work. You need to change the Makefile so that the module version you're creating matches `uname -r`: i.e. change the value for EXTRAVERSION from ".4" to ".4-13", or whatever that last number says on your B2 (my B3 has 11).

Hi,

I bought a Netis Wireless N nano USB Adapter WF2120.

lsusb shows it as:
Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

My Bubba system is a Debian Wheezy system; my /etc/apt/sources.list is: I'm running the kernel version: 2.6.39.4-4.

I builded the custom kernel as adivsed abowe and reboot Bubba 2 successfully.

I setup the network by following advices here:
http://www.cyberciti.biz/faq/debian-ubu ... ess-point/
and here:
https://agentoss.wordpress.com/2011/10/ ... ian-linux/

But, when I'm trying to run the command: I get the messages:
random: Trying to read entropy from /dev/random
Configuration file: /etc/hostapd/hostapd.conf
Line 6: invalid/unknown driver 'rtl8192sfw'
1 errors found in configuration file '/etc/hostapd/hostapd.conf'

I tried with driver names: rtl8192cu, rtlwifi to, but without any success.
Which drivername is walid? How can I find the proper drivername for my usb wireless network adapter?
