Hi, all. My 4-year-old Airport Extreme seems to be failing, so I'm looking at getting either a new Extreme or switching to the cheaper Express. I think I understand the main differences between them, but I'm not sure which would be better for my needs. Here are my specs: 2-bedroom apartment cable internet with (I think) a download speed of 12.5MB/sec 2 users, one with a new iMac, one with a 4-year-old PC laptop nothing else connected to my current router except for a printer I had been thinking that the Express would be fine for my needs, but then I read about the dual-channel thingy in the Extreme. Am I correct that with the Extreme, I could set up two connections: a faster one between the Extreme and the newer modem in the iMac, and a slower one between the Extreme and the older modem in the PC? But with the Express, there would be some sort of mixed old/new network that would slow down the connection to the iMac compared to the Extreme? Obviously, I'm not terribly familiar with these issues... Thanks for any help.
