Wireless card help

[agollach]

I'm running windows vista on a brand new computer... upon restarting my computer (it's a dell) their wifi catcher thing told me something about changing frequencies and standards (went from b/g to a) I agreed because I didn't really know what I was doing. Well anyways, my router doesn't broadcast in a and I'm kind of in a bind.

I went through dell's quickset and wifi catcher to try and change it back to b/g but the option was blacked out. I don't know what to do, I know there must be a way to change it since it was working fine before... also, I have a wireless n card and was wondering why it didn't give me the option of n since my router broadcasts in n.

also, tried system restore to try and go back to before it happened, but the system restore failed.

I suggest you reinstall the drivers for your wireless card. If your computer is not showing the option for N, its because you likely have a default driver installed. If you do that and still do not see the options you need/want, open the device manager and go to your network cards properties. On the advanced tab, you should be able to change it from A, to B/G/N.
