I recently received my tx2500 and am looking to update my home network. The snazziest new router seems to be the Linksys WRT610N which has simultaneous dual-N bands. Does anything actually use the 5.0 GHz band yet? Read here that Broadcom adapters are set up for both 2.4 GHz and 5.0 GHz. But that's a year old. Can I select this with the a/b/g/n/bt radio in my tx2500? Thanks for any help. I won't even start asking about 20 MHz vs 40 MHz specturm availablity. This stuff is pretty confusing.
