Hi, I purchased a usb wifi antenna on ebay, you can see it by searching:

Range Extender 37dBm

The chipset is RT2500 from Ralink and I purchased it hoping I would find open networks, but I cant find any. Will I be able to connect to any other WEP network with this, if so, can you guide me, I read and read and I'm still confused with even where to just start, any help will be greatly appreciated, thanks for helping out, I cant thank you all enough.
