Well, this is my problem. My mom knows NOTHING about wireless connections, so she got a friend of hers to come over and set up our wifi router. The problem is, he set it up as a WEP Pre-Shared. It works excellent for her laptop and all, but the DS doesn't support it. :\ So every time I want to go on wifi on my DS, I have to dig through the router settings, change it to WEP, and then change it back before my mom gets home from work. (which is tedious, and it sucks) So my question is... what are the differences? I was planning on secretly changing it to WEP and trying to get it set up on my moms laptop (because when I switch it from WPA Pre Shared to WEP, it doesnt work on my moms computer anymore...probably because WPA has a password or something?) Are there any speed differences between the two? Which one is safer? Thanks for the help!
