Hi everyone, Long time lurker, first time poster. I recently moved, and I transferred my comcast high-speed internet service. At my old residence, I used my airport express base station (802.11b/g) with my cable modem, and the internet was quite fast. At my new residence, I set up my network and the speed is quite slow. I initially attributed the problem to Comcast, and spent more than an hour on the phone with them this morning. However, I discovered that when I plugged my MBP directly into the cable modem, the internet was blazing fast. So the problem seems to be with the Airport Express. I'm thinking about just upgrading to an extreme, but I wanted to ask people in the forum to make sure there's not some obvious thing i'm missing so I don't waste my money. I don't really understand why my Airport Express would suddenly become very slow when it was working fine last week, but I don't know how else to explain this problem. I checked my speed using speedtest.net. It measured my download speed as 0.79 Mb/s when connected to airport, and approximately 15.5 Mb/s when connected directly to the cable modem. That's a nearly 20-fold difference! Anybody have any ideas? Thanks in advance.
