    Question Opensuse 11.0 and Super-G Wireless networking

    The title says it all. I was hoping to get my Netgear WG311T network card working at 108Mbps Super-G speed. Works fine under winblows.

    I currently use Madwifi and this works fine at 54Mbps. However it does, to my knowlegde, not do Super-G. It does do Turbo mode but this is basically Super-A. I am unsure if using Ndiswrapper would change this. The WG311T is not in the supported cards list so I haven't tried it yet.

    Can anyone advice me if Super-G is possible or if i should just be lucky that the card is working at all

    Regards,
    Bart

    Hi Bart,

    The 'rate' you connect with is dependent on what you tell the card you want to
    connect at. Often if I am distant from a wifi source, I'll shift down to
    11b speeds, which usually give better throughput. (fewer retransmits really)

    If you look at the output of the 'iwlist' command (as root), you will likely
    see some entries such as 'rate11b', 'rate11g', 'rate11a', and so on. These
    are settings which can indicate to the hardware that you want to enable (or
    disable) extra or non-standard features.

    No, I don't know offhand what would enable 108G, but I'd imagine it's
    possible, just not enabled by default since it's not a standard of the
    802.11g protocol.

    an educated guess would suggest that the following command might work:

    iwconfig ath0 rate 108M
    -or-
    iwconfig ath0 rate 108M auto

    The second should be useful, as it allows 108M and anything lower (the 'auto'
    part). makes system gracefully fall back if it cannot sustain the higher
    rate, but always tries to bump up to faster rate.

    A google search of 'iwconfig rate 108M' returned a small number of useful
    results, but looks like that rate is supported.

    Thanks for the suggestions Lornix and my apologies for the VERY late reply

    I tried your suggestions and they don't do anything. No error messages but still only 54Mbps. Windows XP has no problem with 108Mbps by default. Speed is also better with this rate as you would expect.

    Googling I found ndiswrapper should help but I am a bit worried trying to use it. Took me long enough getting this cards working with Madwifi. Think I will just except the speed downgrade.

    If anyone has their atheros card working at 108mbps please let me know how and I will try it as well

    The card may only be running in 802.11b/g mode by default, since Turbo Mode
    is not supported by ALL devices.

    From the MadWifi Wiki:

    How do I get my card to use turbo mode?
    http://madwifi.org/wiki/UserDocs/TurboMode

    Seems to be a better answer than I could do.
