    I had Verizon fiberoptic internet service installed in my home 2 months ago and I noticed the Verizon modem/router uses 802.11b and 802.11g for its wireless connection, but not 802.11n. I use only the 802.11g band for my Wi-Fi connection to my notebook PC and the speed seems very good, but I'm curious--is 802.11n expected to supersede 802.11b/g for Wi-Fi and wireless internet broadcasting eventually and, if so, when is this expected to occur? The Wi-Fi card in my PC (Dell XPS M1330) does not transmit on 802.11n, so I expect I will have to upgrade the card when 802.11n is the new standard.

    No. 'n' cards and routers have backwards compatibility with 'g' so you're unlikely to have any problems for the forseeable future.

    b/g is 2.5 ghz while n si 5ghz, most routers I've seen can't simultanously work b/g/n it's either b/g or n so it's not woth geting n unless all your devices are n capapble.

    b/g is 2.4

    certain N is 5ghz.

    Also N can have better range and coverage for a house.

    N can also give you higher bandwidth to take advantage of your fast internet connection.

    Our internet connection speed is approaching the limits of what wireless G can offer in terms of bandwidth. With my cable broadband internet, my wireless G router always limits my download speed to around 20-25mbps download speed. Getting an wireless N with a computer which receives wirless N signals will improve your download and upload speed.

    Sorry dude - you're as wrong as the person you're trying to correct.

    Wireless A is 5ghz, B & G are 2.4ghz.

    All N routers broadcast on the 2.4ghz and 5ghz frequencies. However, only Dual-Band N Routers have the capability of accessing the 5ghz band as a separate network. Single band N Routers use an overlapping of the 2 frequencies to increase signal and range, also known as Multiple In, Multiple Out (MIMO) technology.
