Add, Don't Replace When Upgrading to 802.11n
Those of you who have slogged through the entire Performance test sections of our draft 802.11n product reviews already know the "dirty little secret" that I'm about to describe. So, if you get cranky when you feel that your time has been wasted, you can move along...there's nothing here to see.
But for the rest of you contemplating taking the plunge on a year-end draft 11n upgrade, I'm going to give you a few reasons to think about keeping your current 11g router and running it along with your shiny new draft 11n purchase.
The secret is that the current crop of draft 11n consumer routers handle two things quite badly: mixes of draft 11n and 802.11g clients; and any security option other than WPA2.
