Hello all, I have noticed lately that my DL/UL speeds are not what they should be and was just looking for some clarification as to why. My main machine is PowerMac G5 quad connected to my network via WiFi and I have a consistent DL speed of 7Mbps and an UL speed of ~5 Mbps. I have a Zoom modem and the Apple EBS. My wife's iMac (Late 2009 21.5") , which is also connected to the network via WiFi, gets consistent speeds of 20+DL and 15+UL. Is this difference simply due to the fact that her computer is using 802.11n and I am limited to 802.11 b/g (via installed airport extreme card), or is there a configuration that I should be using that would increase my speeds? I'm also on a super budget so upgrading components is not an option. So if I am stuck with these speeds due to hardware limitations, then I will accept that; even if I don't like it. Thanks everyone in advance for your time and advice.
