    Re: EW-7728In, Ralink chipset problem with drivers

    Just (re)installed the driver as per instructions, the outcome's the same:
    1) The device comes up
    2) I can see all wireless networks
    3) My router prompts for the WPA password
    4) it fails to connect

    I then disabled the security on the router and could connect without any problems so I guess this would point to the Security setting.
    the log shows these errors, but not sure if this is the problem:

    Hi folks

    I had read that the drivers for this card, which I've just bought, were built in to the latest kernels - certainly for 9.10 and 10.04. Initially my wireless wasn't working with this card and my router - and I almost thought about compiling them from the v1.8 source drivers at the Edimax website. I'm running 10.04.

    but a few posts on here mentioned unhiding the SSID. Mine was hidden - worked fine when connecting to a Belkin G USB dongle previously - but when I unhid my SSID the Edimax card found the router and connected no problem and has been working really well since!

    It does appear it just doesn't like hidden SSIDs much!

    Hi,

    I just purchased this card to install in an older Dell desktop running 10.04. So all you had to do was install the card, boot up and it worked straight away? (as long as your SSID isn't hidden - which mine isn't)

    Thank you.
