how do I force cellular data while on Wi-Fi
Here is my problem: I want to run airplay from my iphone to a stereo in my garage that is under my house. I bought an airport express and put it in my garage and ran a 3.5 mm jack from it to my stereo. The problem is the range on the airport extreme ***** and does not reach to my garage, which is 30 feet away down one level. If I use the airport express as an extender I get horrible skipping, which is a known problem. I can use the airport express as an "internet device" and stream to it. The problem is the signal ***** in the garage and I have to put my iPhone in a closer room to get a strong enough signal. The only solution I can think of is to use the airport express in the basement as a seperate network and then I will have a strong signal. The downside to that is I have no internet to it. Is there a way I can force the iphone to use cellular for data?
I am sorely dissapointed that I have $200 of apple "It just works" routers and I can't use airplay. I have tried different channels, and tried both wireless G and N. I live in a wood framed house and have 0 wireless home phones. I should have minimal interference. My range of the airport extreme should be more then 30 or 40 feet. Any help on this would be much appreciated.
