For Flash, this from the Downloads section (getFlash10) worked for me:
NOTE: You must have already downloaded the browser and OSS.
You must have started the browser at least once!
You must have OSS started with the sound on menu option.
Then select getFlash10 from the Apps menu.
.
If you already have your tce directory setup, then a flash10.tcz
will be installed there, otherwise it is in /tmp/tce/. flash10.tcz
will be loaded upon completion of the getflash script.
Sorry, I can't help with the wireless -- I'm one of those primitives who's still chained to his desktop...
