    I have Realtek RTL8187 wireless 802.11b/g network adapter. would it need to be b/g/a in order to handle 5ghz?

    Thanks

    Typically the dual band adapters support 802.11 a/b/g/n. 802.11a is an outdated 5 GHz spec.
    Confusion arises because the 802.11n spec supports both 2.4 GHz and 5 GHz bands.
    Spec Recap
    802.11a = 5 GHz only
    802.11b = 2.4 GHz only
    802.11g = 2.4 GHz only
    802.11n = 2.4 GHz and 5 GHz
    802.11n adapters can be single or dual band.


    The latest spec on the 5 GHz band is 802.11ac. It can run speeds over 1 megabit per second.

    Ah, the RTL8187. I have two of them sitting here on my desk. Since it is "b/g", it is 2.4 GHz only.
