Help with Remote Play

The scenario:

Dad only turns on internet from about 5 - 9:30 :evil:

I wanna use Remote Play at night when i go to be, about 11:00 so I can listen to music on my PS3 (Putting on PSP is not possible, don't wanna do it anyway)

Everywhere I read it just says to use Register Device (did) then remote play on both systems (did)

PSP always times out.

Is it not possible for PS3 to transmit DIRECTLY to PSP?

Do I NEED a wifi connection on the PS3 always? :question:

Cause from 9:31 to 4:59 the next day I don't have internet! :cry:

HELP! ;)

Ah damn.

I checked for one when I first got.

I can get a connection when I'm in my mom's bedroom right next to the window on my PSP but thats about it.

PS3 is in the living room, 2 rooms away.

Anyone know of any hacks or anything for this occasion (If that is illegal to talk of, sorry I'm new here so please don't lock and disregard that last part!)

Anyother help at all
