Candidate for Deletion
The device has been tested with both, WEP as well as WPA mode, using a FRITZ!Box Fon WLAN 7050 (UI), Firmware-Version 14.04.01 as AP and is currently transmitting this page on a Sony Vaio PCG-SRX51P Notebook with D-Link PCMCIA USB 2.0 Adapter. If you need more help, please look to the WifiDocs page for more support channels or check
~$ man interfaces
- for configuration options.
Device Type: USB
Feisty 7.04 (Kernel 2.6.20-16-generic)
- The rt2570 vanilla driver works both for 32-bit and 64-bit.
Dapper 6.06 (Kernel 2.6.15-19-386) & Breezy (Kernel 2.6.12)
Did it configure during install?
YES for Dapper, NO for Breezy
Did it work by just configuring network settings after install (out of box)?
NO, the packaged driver will freeze the system on
~$ sudo ifup rausb0
- only powering down and up again will help.
(this looks like bug https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.15/+bug/39391 )
What driver did you use and ease of set up?
Please make sure you have the appropriate Kernel-Headers and GCC in place.
Download the tarball to the current directory and unpack
~$ wget http://rt2x00.serialmonkey.com/rt2570-cvs-daily.tar.gz ~$ tar -xvf rt2570-cvs-daily.tar.gz
Go into the source directory and compile
~$ cd rt2570-cvs-<timestamp>/Module ~$ make
For Dapper: Make a backup copy of the actual driver ( you never know... )
~$ mkdir rt2570-backup ~$ cp /lib/modules/$(uname -r)/kernel/drivers/usb/net/rt2570/rt2570.ko \ >./rt2570-backup/rt2570.ko
For Breezy Create the proper directory for the new driver
~$ sudo mkdir -p /lib/modules/$(uname -r)/kernel/drivers/usb/net/rt2570
Now copy the freshly compiled driver to its place
~$ sudo cp rt2570.ko /lib/modules/$(uname -r)/kernel/drivers/usb/net/rt2570
For Dapper Unload the current driver ( after you removed the USB WLAN Adapter )
~$ sudo rmmod rt2570
Register the new driver
~$ sudo depmod -a
Load the new driver
~$ sudo modprobe rt2570
Now edit the configuration file "/etc/network/interfaces" ( do you need a backup copy ?? )
~$ gksudo gedit /etc/network/interfaces
and add the following for WEP with DHCP
iface rausb0 inet dhcp wireless-essid myapname wireless-key s:myplaintextpassword auto rausb0
or the following for WPA with DHCP
iface rausb0 inet dhcp pre-up ip link set rausb0 up pre-up iwconfig rausb0 mode managed pre-up iwpriv rausb0 enc 3 pre-up iwpriv rausb0 auth 3 pre-up iwconfig rausb0 essid myapname pre-up iwpriv rausb0 wpapsk myplaintextwpapassword pre-up iwconfig rausb0 essid myapname auto rausb0
Reinsert the USB WLAN Adapter and issue
~$ sudo ifup rausb0
The Network connection will be made. If not, issue
~$ sudo dhclient rausb0
Repeat a few times with pauses if necessary.
Comments, tips, or other set up help...
To install basic compile support
~$ sudo apt-get install build-essential gcc-3.4
