I'm not sure you can find something that cheap in store. But if you want a big selection with a pretty good price range, I'd go with Frys Electronics. Frys is where I usually go for all my in-store electronic buys.
There isn't any software based way to increase the range. There was an old hardware hack for the 1000 that stuck on an antenna, but it killed the portability of the PSP and made it hard to hold.
id like to learn about that hardware
i see... i hope one comes out soon.. but im just hoping for a solution thats cheap and fast my best solution right now is wifi max at circuit city thanks +rep for u!
Is it actually possible to forcefully increase the wireless range through software, on any system?
