I've been having problems with Internet slowdowns and reliability. After reading this month's Macworld article about troubleshooting your Internet connection, I tested my cable speed straight from the modem and got the fastest speed I've gotten in a long time, 19.5 Mbps down. After connecting back through my AirPort Express (802.11g), I was back down to ~9 Mbps. I'm sure part of the problem is the old cables in my house that have been split 3 times before getting to the modem, but there's not much I can do about that. Could upgrading to the newer 802.11n AirPort Express make a difference for me? I'm sure I could get faster tI'm trying to speed up my network as much as I can before I have to switch broadband carriers when I move, this local ISP is much slower than Comcast.
