Right so.
My wifi used to work, right? A few couple of months ago... I can't tell you how long it's been, since I just started playing pearl again after several months.
So when I try to connect it gives me the error 52100. (What happens exactly is that the little bars (Idk what they're called) are red for a few seconds, then they turn green and stay green for about a minute then turn back to red.) So I went to the Nintendo Wifi website but that didn't help at all.
I've tried resetting my router, going to the router website (You know, the one where you put the IP in your adress bar?) and turning off the firewall and allowing my DS's MAC address. None of that has helped.
I tried upgrading the firmware for my router, but when I try to open the file to do so, it gives me this thing like, "Windows could not find a program to open this file with", or something to that effect.
So help me out guys. (If it helps, I'm using a Vista and my router is a Westell 327W/B90-327W15-06)
