I bought one of these about 12 mths ago: http://www.jaycar.com.au/productView.asp?ID=YN8306&keywords=high+power+wireless+n&form=KEYWORD
I downloaded the drivers from the link above then installed them on a windows computer. How do I use these linux drivers/installers on the raspberry pi to get the wireless adaptor to work?
Will this work with the Raspberry Pi?
Fergus, with a bit of luck, you may be able to ignore those build instructions altogether, and just do a network package install of the driver you need. Take a look at this post by GizmoB73:
Although I don't know whether it resolved his own problem, he points out that the rt2870 chipset is handled by the regular "ralink" driver, which you can install directly on your Debian with nothing more than:
Unfortunately I don't have my Pi yet and I'm not running Debian here on any machine, but it's worth a try doing the above install command, then running "depmod -a", and finally running "modprobe" on the right kernel module that the apt-get installed.
To find the module name, run "uname -a" to discover your kernel version/build name (it should be the 3rd field of the single line of output, for example 3.2.0-xxx), and then use that name to look in the appropriate wireless modules directory:
In that directory you should find a number of driver modules (.ko files), and with a bit of luck that will include a rt2870.ko --- if so then try "modprobe rt2870". If it's not there then you could try one of the others, although that can lead to a crash sometimes.
It would be so much easier to give proper advice if I had a Pi, grrrr ... Good luck!
