Best (& cheap) USB wireless dongle?
I'm looking for a good cheap USB wireless dongle for my in progress car PC setup. My priorities (at my best rough guess at priority order) are:
1. Allow adhoc sharing with a laptop in the car with full security enabled. This is critical since I'll be remote desktopping into the car PC until I get my LCD set up (which I know will take me forever :)).
2. Allow a laptop to share the car pc's T-mobile internet connection (when I have the phone hooked up).
3. Allow the car PC to connect to my home WAP to synchronize my music collection off my home network. This may be more critical given I've found I can run the PC off my 7.2Ah battery for 20 minutes or so which makes a delayed shut down with sync over the wireless network a much more viable possibility.
4. War driving (the phone connection is *slow*!).
Any thoughts? Cost is probably one of my most driving concern at the moment. Also, it needs to be small since I'm intending to have it sticking out the back of the computer directly.
I didn't see any specific product recommendations searching the forums, hence the question. Thanks in advance.
