I did on an Apple forum but I didn't see much action on it.
I have the dlink router on now, it's a good router. Last night I was out at a wi-fi spot and tried the Itouch and the response was immediate and it located me right at that spot. This morning at home I tried to locate at first it kept the location from last night, finally after a while maybe 10-15 minutes it finally placed me in the middle of a field about 250 yards away, close yes, but with the cisco g router it locates about 10 yards from my actual location, and instantly.
Very odd.
