I just want to check that this will fix the problem I have. I'm in the UK and have a BT wireless router downstairs, the one that on the adverts lets 3 people use it all at the same time all round the house for everything from surfing the net to watching movies. Mine (and I've changed it three times) has a strong signal by the router, cuts out if two of us are on the internet, and drops signal if you're more than about five metres from the router. However the download rate is good - 9-10 mbps, so when I do have a signal, it's a really good one.
My house is not huge, and the downstairs is shaped like an O - I have one wall in the middle of the house and that's it - no doors or anything that could block a signal, but for some reason, I get a rubbish signal at the opposite end of the house, virtually no signal upstairs (have to rely on 3G), but a strong signal by the router. I've had BT round and they've even moved my phone line from one end of the house to the other - whereever I place it I have a good signal, but at the opposite end it drops to 1 mbps. At the moment we've got it near the dining table for when we're working/playing games, but my wife would like to use her iPad upstairs in bed on the weekends, and at the moment she's having to use my iPhone's 3G.
Can I plug in an Airport express somewhere in the house to 'boost' or amplify the signal so that I have a good signal all around the house? I think this is what the airport express does, but the literature on the info page says to plug it into your router to set it up. I would want this plugged into a socket at one end of the house, with the router at the other end, so that I have a better all round signal. Can this be done with an airport express? And can I do that without wires? And without having to plug in another phone cable?
