Could you help me with my internet?

[Cerezoss]

I have wireless internet here, and I'm on the attic, I use a 300N USB Adapter as a receiver
and my connection is really poor.
I'd like some tips, really, but here's my thought on the matter thusfar:

Buying a new Modem/router: I will propably get lots of shit from my parents saying we don't need one, but
it might be enough to send in a stronger signal, yet, this one is -supposed- to be fairly good.

Installing a wireless 300mbit pci adapter card: It's cheaper than a new router/modem and I won't get shit
from my parents, and the thing is a whole lot easier to install than setting up a new network as well.

I would like some feedback and tips on how I could improve my conection without doing something
drastic / expensive. (Over 40 euros)

How far from the router are you?

[Cerezoss]

Second Floor / Attic, opposite of the house too.

That's most likely the problem, and I doubt a different router will help too much. =/

I could be wrong, though.

could send the signal to the second router and the second to his PC

or get ethernet

Just wondering, are you getting poor connection speeds or constant drop of the connection?

Set up a hop point somewhere in between.  That should amplify the signal enough.  I can't guarantee good latency though.
