What I have found best for setting up the wep key on the router is to set it manually. I use numbers and letters a through f in combination and take care to enter the letters in lower case. It's then easy to enter the identical key onto the braillenote. The key is definitely case-sensitive. For most home use, this works just fine and does provide what is probably a quite adequate degree of security.
As Jeff pointed out, you can also employ mac address which limits outside access even further. You should be able to locate the mac address on a printed label on the underside of the wireless card. Note that the mac address is specific to the wireless card you use and not to the braillenote itself. So, if you have one wireless card and two braillenotes such as in a family, the same mac address works for both units. Don
