Do I need 108 Mbps??

    Hello all,

    I recently purchased the Linksys 802.11g router & adapter for my home. To
    make a long, painful story short, I'm very pleased with the router, but
    ended up exchanging the laptop adapter for a Netgear 108 Mbps card.

    So far so good. The difference in surfing speed is clear going from the -b
    to the -g spec, but with this 108 mg card, I'm now getting greedy. Is there
    really any more to be gained from going up to the Netgear 108 Mbps router?
    My knowledge of networking is nil, but my cable connection isn't even as
    high as 54 Mbps, is it?? I have the run-of-the-mill Comcast setup.

    Thanks for any info.

    There's no network surfing advantage at all in 108. In fact, there's no
    network surfing advantage in going from 802.11b to 802.11g. If you have
    ADSL, then (depending on what level of service you have), you may get
    anywhere from 384 kbps to 1.5 mbps. If you have cable you probably get
    somewhere between 1 mbps and 3 mbps. Unless you have a lot of devices on
    your home network chattering at the same time, 802.11b gives you far more
    than enough speed for the internet.

    That said, I'm a believer in getting 802.11g adapters, for a number of
    reasons I won't go into here. The 104 mbps feature is vast overkill for
    almost all users, and it's non-standard. I wouldn't pay a premium for it,
    but I wouldn't reject a reasonably-priced router just because it has this
    feature.

    The trouble with the 108 is that is uses all three available none
    overlapping channels. So if you have a neighbour with wireless then you will
    get interference and so will have to reduce to the single channel mode
    giving you the same 'g' performance.
    Conversely if your signal is stronger than his, then you might be ok, but
    your neighbour will have problems.

    Not a very good solution until they give more bandwidth to the 2.4G spectrum
    which is not likely to occur quickly

    This is true. But you're more likely to cause a problem for your neighbor
    than the other way around. Bottom line, whether the feature works or not,
    it's useless for internet surfing. If you're swapping gigabytes of mpeg and
    mp3 files between nodes on your wifi network, then it might be useful - but
    you won't get 108 mbps real througput, especially not with already
    compressed data.

    Just to clarify. If your ISP gives you 3 mbps raw bandwidth, then you can't
    possibly surf the net faster than that. Your 802.11g 54mbps connection
    allows you to zap every IP packet to the router at lightning speed, where it
    sits and waits for the modem to drain it at a rate which is, at best, 18
    times slower. It's still more than three times slower than the max 802.11b
    bitrate.

    I'd buy 802.11g, but the reasons have nothing to do with surfing the net
    faster.

    I agree 'g' is better for reasons of reception. having used both 11M and 54M
    there is no comparison in performance of getting a signal. With the 11M
    stuff there were two rooms in my house where no signal was received by my
    laptop.
    Now I can surf anywhere
