I have a client who lives in a big house - well, a castle... - and the wireless performance there is just ridiculous. They literally have about 6 phone lines, each with an Internet connection and a router. So, naturally I want to both cheapen and improve this somewhat, because connection stability is rubbish. What I'd like to do is have a decent router in a central location, and then just use wireless extenders to improve the signal in various wings of the building. Is chaining extenders together something that's possible? If not, what's the best solution?
