Ravo W54-AP firmware
mirrored by Vidar Holen, http://www.vidarholen.net
It seems Ravo has gone belly up and taken all the docs and firmware with it. I had a copy lying around, so I might as well mirror it now that google is incapable of finding it anymore: W54-AP_v3.00.05_3in1.trx. There's also the manual, which google had plenty of.
