1. Investigate
What wireless brand and specifications do you have?
For example I have this worthless piece of crap they call a wireless USB device.
- Asus WL-161
- 802.11 b
- USB 1.1
- data rates: 11/ 5.5/ 2/ 1 Mbps auto select.
- WEP 64/ 128 bit
Look at your hard copy manual and box for info or google your device numbers. If you are using built-in wireless on a laptop google your laptop brand and numbers for further clues.
