Permanent drop in internet connection from airport express
Hi,
Around 6 months ago, I set up a wireless network composed of an airport extreme - as the main base station, connected to a router - and an airport express to extend the network into the other room. During this time, it worked successfully. But, today, out of a sudden, the internet speed, when connecting through the airport express slowed dramatically, independent of which device (macbook pro, iPad, android smartphones, Apple TV...) is used. The point is the problem only occurs when connecting through the airport express. If I move the laptop to the adjacent room and connect through the airport extreme, it works perfectly.
Has anybody dealt with such a situation? It does not appear to be related to wi-fi channel interference, since a wi-fi scan showed that the airport express has been operating in a channel not used by any other router.
Thanks.
