I have a shiny new DS Lite, and a laptp that's wireless enabled. I wanted to get a router so I could play with my DS online.
So I went into Currys. Was having a look, and found something that went on about sharing broadband. Didn't say wireless, but did say router. So I picked it up, and took it to the sales guy. Explained what I wanted to do, and he agreed it would be fine. Double checked, because it doesn't say wireless on it. Yep, it will do what you want it to.
Got home, got it set up. Nowt.
Asked a friend who works with computers and generally knows a hell of alot more than the average turtle. Got the response of "Which idiot sold you that?" Apparently, it's nothing like what I need.
Yes, I should have done my reasearch better, and written down and exact model or something. But is it not their responsibility to give the correct answer? I'd have accepted "I don't know." - it's the fact that they assured me it would do what I wanted that annoys me.
