    Could someone explain it to me? I'm a graduate student working on a lot of public WiFi networks, as well as home networks. Can I have both channels enabled simultaneously - might they interfere with each other, or draw battery power more? Any ideas?

    thanks!

    Wireless G operates at 2.4 GHz, and Wireless N operates at 2.4 and 5.0 GHz.

    2.4 GHz will interfere with cordless phones and microwaves, but usually not noticeably. 5.0 GHz doesn't interfere with much.

    Also N is much faster and the range is much better...
    If you have a compatible laptop (US SZ or TZ) then go for it!

    You can use WLAN to disable 5ghz if you know the router your using doesnt broadcast at 5ghz. The utility tells you they interfere with one another. I noticed i have a more stable signal and transfer rate with just one activated. My router is a basic n and so the max i can achieve is 130mbps through 2.4ghz.

    Always keep in mind that unles you're sharing the wifi and/or transfering files wirelessly over this network, that the hard line (cat 5/6) only operates at a max of 100mbps.

    By deactivating one of the frequencies you can reduce chances of interference within the card itself, unless you have a router broadcasting at both frequencies in which you can benifit from speed/range. Using one frequency may save some power too, but that is very debatable.
