I’m doing a post-move reorganisation of my network, so I purchased a WiFi adaptor to go with my non-WiFi-enabled ARTiGO. A very small amount of fiddling was required: Create /etc/udev/rules.d/10-wusb100.rules with:
# UDEV-Rule for wusb-100v2 ID 1737:0078 SUBSYSTEM=="usb", SYSFS{idVendor}=="1737", SYSFS{idProduct}=="0078", RUN+="/sbin/modprobe rt2870sta"
and then:
$ sudo /etc/init.d/udev reload
(or just reboot)
