I have two airport expresses that join my wireless network, and each into a hi-fi. The unit closer to my wireless router works flawlessy, but the second unit which is a little further away cuts out every now and then for a few seconds at a time. I suspect that my original wireless signal is too weak, and that a stronger router (a la airport extreme) is required. Is there any way for me to measure the signal loss? Can I be sure that an airport extreme will solve the problem? My broadband is by http://www.plus.net/ (I'm in the UK) and I only have their basic supplied router, a Thomson model, apart from the two airport expresses, of course Many Thanks for any help!
