I have two WiFi routers in my home. One is a nice Airport Extreme 802.11 n, but the signal is very weak by the time it reaches the end of the house where I work. So I dug up an old Linksys 802.11 g to connect in this end of the house. Whenever I am in this room, I need my iPhone to connect to the Linksys router. But there is still about half a bar of signal from the Airport Extreme in the other room. The iPhone keeps trying to connect to that, I assume because it gives an 802.11 N signal higher priority over 802.11 G, even though the G is closer and has a much stronger signal. Is there any way I can fix this, or am I stuck having to manually switch connections every time I walk back into this room?
