Which wireless usb adapter for me?

[MAMAFUFU]

I just bought a Linksys wireless router(802.11b) and linksys usb adapter(also 11b).
As the adapter is about 60ft and 4 block of walls away, it constantly drop line.

Can anyone recommend a usb adapter that's better at picking up weak signal?

Try building this homemade antenna first.

What does your signal strength look like? I would recommend switching channels on the router first to see if you can find one that works a little better.
