[quote=silvarios]If your current router is single band, you are stuck with 2.4 GHz no matter what devices you own. I don't think I've seen a consumer, 802.11n, single band router that only offers 5 GHz. Your main point stands, even if you had a dual band router, you'd be stuck with 2.4 GHz mode on account of your single band devices. Simultaneous dual band is quite helpful for this kind of setup.

You are likely correct with the first part. I just vaguely remember I can't get my router out of the 2.4GHz range. As far as dual band goes, I thought any router that was specifically sold as "dual band" could do both simultaneously? There are some that can do one or the other, but they're not sold as dual band. No?

Not sure what "sold as" means, but my Express is dual band, not simultaneous dual band.
Netgear had this to say:
