I need to replace my USB wireless adapter. I had a Motorola that recently died and got a replacement that doesn't work for me because although it can see the networks the signal is terribly faint and it won't connect.

Currently I'm figuring on getting a similar Motorola but don't want to end up with another low-power piece of equipment that doesn't work.

Does anyone have any recommendations? I don't need anything fancy, I'm just connecting my PC to a local network.
