Also, what kind of router? You may want to try this: 8320 Stable Wi-Fi UMA Connection Settings (Linksys)
It switches when the phone is within three feet of the router. I just said that it worked in other rooms as a reference to the fact that the range is there. BTW its a linksys WRT54G. I will look at the link you gave, but i'm not sure i know how to change all those settings.
