    Ubuntu 10.10 & USB Wireless adapter

    Hello, I have installed ubuntu 10.10 on my 32-bit laptop that has wireless switch broken. On windows I used a usb wireless adapter to connect to wifi. The problem is, ubuntu automatically tries to connect to wifi through the internal wireless card and I don't know how to change that so that i would connect to wifi through usb wireless adapter. If im not wrong, the ubuntu has no problem making that usb wireless adapter working(it shows up in the list of connections), the problem is that it tries to connect through the internal one. I would be very greatful if someone would help me on this. If you need more info, just say because I don't know what kind of information you might need to help me.

    Btw, sorry for my broken english

    Re: Ubuntu 10.10 & USB Wireless adapter

    Hi,

    several things:

    1. Ubuntu 10.10 is outdated. Therefore I recommend installing 12.04 Long-Term-Support (Upgrading via 11.04 and 11.10 takes too long)

    2. Which hardware is in use?

    Please show the outputs of
    Code:
    lsusb
    lspci -nnk | grep -iA2 net
    lsmod
    3. Check this thread: Unload the pci-driver when the stick is in use via udev-rule:

    Re: Ubuntu 10.10 & USB Wireless adapter

    Hi praseodym and thanks for helping me!

    I am using ubuntu 10.10, because this laptop is not very good in specs(512 ram, 1.5GHz cpu) and I'm afraid the latest version of ubuntu would not run so well(ubuntu 10.10 runs very fast, the speed is uncomparible with sluggish winXP). And the only method I can install an OS now is through usb flash drive, but I have a problem with it(http://ubuntuforums.org/showthread.php?t=2038772). Currently I don't have a computer that could burn iso's into disks. Besides, I only need few programs on ubuntu. To be exact it's eclipse ide, android sdk, text editor, website browser, dropbox.

    The console output I got from those commands is:

    Code:

    I tried the udev-rule and it didn't work. It still tries to connect to wifi through the internal wireless card(at least it shows me that). And after some time of trying to connect it asks me for password again(the password is good, i checked it alot of times).

    Re: Ubuntu 10.10 & USB Wireless adapter

    If Ubuntu is slow then Lubuntu or Xubuntu 12.04 are good candidates.

    You need to replace "b43" in that rule twice with "ath5k".

    Re: Ubuntu 10.10 & USB Wireless adapter

    Additionally, you need to copy the firmware to the right place in 10.10:

    Code:
    sudo mkdir /lib/firmware/RTL8192SU
    sudo cp /lib/firmware/RTL8192SE/rtl8192sfw.bin /lib/firmware/RTL8192SU/
    Reload the USB-driver:

    Code:
    sudo modprobe -rf r8192s_usb
    sudo modprobe r8192s_usb
    The stick should work now with the channels 1-11

    I had lubuntu 12.04 installed, but there was the same problem with wireless and when I uninstalled it I can't boot from usb no more(http://ubuntuforums.org/showthread.php?t=2038772). I had ubuntu 10.10 on cd so I installed it instead.
