    isl3887usb Problem

    I am installing Arch Linux on my computer, however I cannot get wi-fi. I know from using Ubuntu that I use p54 for my wi-fi adapter. When I type "dmesg" I get a lot of messages that tell me that I need the isl3887usb and isl3887usb_bare files, so I go to the kernel wireless page and download the file: Rename it both isl3887usb and isl3887usb_bare and move it to /lib/firmware and do "modprobe p54usb" and then "iwconfig" but nothing changes. I type "dmesg" and the same thing happens. So nothing happens. Any ideas?

    Hello and Welcome.
    I'm not very familiar with Arch Linux but it should be the same basic steps as any other Linux, Click the Wireless link in my signature to get started with Wireless and Linux. Try to use the code tags as mentioned in the link. If the wireless script doesn't work correctly, then post the info manually if you can. Good Luck.

    I'd rather be lost at the lake than found at home.

    Just to be sure, this is a usb wireless adapter, right?

    Post the output of
    dmesg | grep firmware
    Are you sure you downloaded the correct firmware? From the p54 wireless site, isl3887 would correspond to the download for kernel 2.6.29 and above. It looks like what you downloaded is for older kernels.
