I have a very weak connection through my Airport Express. By this I mean not a single Spotify song can play without being interrupted.
My computer is located 6m from the Airport Express in a straight line, with no walls or other obstacles in the way. No DECT phones and no microwave turned on.
Wireless speedtest: download of 0.52Mb/s and upload of 0.07Mb/s
Wired speedtest: download of 23.34Mb/s and upload of 1.80Mb/s with a ping of 43ms.
iStumbler 6m away tells me signal between 35% - 45% and noise around 20%. iStumbler right next to the Airport Express tells me a signal of around 55% - 60%.
Up until last week things were better, in the sense that Spotify played uninterrupted unless I visit heavy webpages or download big files.
It seems my wired connection is good enough but wireless is awful. How can I fix / debug this further?
