    Re: wifi trouble

    i'm new here but not new to computing. its easy to see that the wifi problem is not new to ubuntu.
    i had hope of leaving windows but i dont want a new technical saga adventure like we had in the early days of win/io/interupts
    etc,etc. so i wont hold out much hope!!

    Re: wifi trouble

    Wifi issues affect the broader Linux ecosystem, not just Ubuntu.

    Unfortunately, until OEMs make Linux drivers for their hardware more common we will continue to have to struggle and find work-arounds.

    It is not a wise business decision for many OEMs to expend the resources to maintain drivers that work for such a small segment of the market, so they concentrate on Windows. I don't blame them.

    Re: wifi trouble

    A good first step would be to report the output from one or both these commands. If your wifi adapter is internal, type this in a terminal:

    Code:
    lspci
    If it's a USB 'dongle', type this:

    Code:
    lsusb
    What we're looking for is something like this:

    Code:
    :~$ lsusb

    There are families of devices that have similar characteristics and similar fixes. The actual manufacturer of the device isn't that relevant, what's relevant is the make and model of the chipset in the device.

    Re: wifi trouble

    The plot thickens!
    the seller uploaded a zip file with the driver disc data that i lost,my dvd "ate" the disc.
    i copied the zip file to a folder on my win 7 comp.and also extracted the file to that folder. then copied both to a thumb drive,to my ubuntu comp.no matter what i try on ubuntu i get errors.
    so,back to win 7 comp. i disable the internal wifi and run the realtek driver for win 7,THIS COMP,and i am now connected with the widemac/realtek usb wifi on win 7 so i know it works!!,but alas not on ubuntu??

    i tried extracting on the ubunto comp but get errors when i run it??
    so im lost again

    Re: wifi trouble

    So i guess im in the same boat as many others, no answers,and i was very much looking to use ubuntu.
    im using my usb wifi adapter on my win 7 comp as a very sucessful test. i think its better than the built in wifi in my laptop.
    i installed the win driver and it works as you can see. (im on win 7 now)
    i cannot get the ubuntu driver to setup. in fact cant find setup. when i extract the driver package on my linux comp and try anything i get errors that i dont understand.
    the usb unit connects without the drivers but looses connection.
    last call?
