    Default WiFi Data rate.

    After my recent problems with co frequency interference, the actual 'Data Rate' details have had me curious.
    I am sure the router is supposed to 'handle' 300 mbps but does it and what governs that rate.
    The desktop not 2 metres from the router shows a 'flow' of 150mbps but when looked at a L/top, it wasnt showing anywhere near that rate and neither 'rate' alters if that computer is the only one on line, so why the difference ?
    Its something I am grappling with but from what I have learnt since we went digital with television, signal strength is only a part of the equation, QUALITY or BER is the main factor so even though you may have a good signal reading, if the data flow is low it causes problems or is there something else I am missing?
    I stand unequivicably behind everything I say , I just dont ever remember saying it !!

    Hopefully, these links will provide some useful information.

    Concerning wifi connection speeds .

    I couldn't find a review of the NetComm 3G18WV, but there is a useful review of the NetComm 3G18Wn at with signal strength and throughput tables, and other comments, which might expand your knowledge.

    An 802.11g Wi-Fi device (2.4 GHz) in close proximity to a network router can onyl connect with a data rate of 54 Mbps maximal. For 802.11g, the defined ratings are (from highest to lowest)

    54 Mbps
    48 Mbps
    36 Mbps
    24 Mbps
    18 Mbps
    12 Mbps
    9 Mbps
    6 Mbps

    Similarly, old 802.11b (5 GHz) devices supported the following ratings

    11 Mbps
    5.5 Mbps
    2 Mbps
    1 Mbps

    Data rates up to 600 Mbps are achieved only with Wi-Fi 802.11n ( can be enabled in the 5 GHz mode, or within the 2.4 GHz mode ) and the use of four spatial streams using one 40 MHz-wide channel. See also:

    Very interesting and not what I expected at all to read about the data rate.
    This netcomm version they tested is almost identical to the one I have but has 2 antenna where I have one.
    There is also cosmetic differences and placement on the front panel of the display between the two but beyond that I would be surprised if to all intents and purposes, they arent identical.
    I too had hell's own job getting mine set up to the point where Netcomm had to do a 'Remote' and even that took them several minutes so except for changing channels on the WiFi I am not touching it.

    Would you have named the type of Wi-Fi in use, I indeed could have saved my efforts ... Until now for me it's not obvious which type of Wi-Fi used.
