The only explanation I can get is that you had recently changed the clock settings.

This is where the problem began: I know DSs aren't compatible with WPA keys, so I removed the encryption. I tested the connection, but still, no signal was detected! Yeah, I even did that with my DS exactly at the spot where the router was, and I still got nothing! Could you please help me?
NOTE: I don't know if this factor counts, but here it goes: the first router was pen-enhaced, while this one is based on a phone connection.
