Wirless in old house, thick walls

[Jon12345]

My router is downstairs and I have a PC upstairs. It gets the signal fine. But in my bedroom, my iphone can only pick up one bar (and often nothing) from my Netgear DG834G a/b/g router. Since I want to use Skype on my iphone, I need a much better connection!

If I get one bar wireless on my iphone using g protocol on that router, what would a wireless n router give?

Thanks,

Jon

I've just checked and the iphone only supports wireless g. Does that mean that a Wireless n router wouldn't make any difference because the iphone can only pick up the g signal?

I have a spare Netgear DG834G v2 router. Could I use that upstairs as an extender?
