    Wireless not working after clean install

    I have just installed Kubuntu 10.04 on an IBM ThinkPad A30P.

    512MB RAM, 48GB harddrive, ATI graphics
    Ethernet is working fine
    Wireless is not working - IBM High Rate Wireless LAN Mini-PCI Adapter with Modem (Harris Semiconductor/Intersil Corporation Prism 2.5 Wavelan chipset (rev 01) )
    It is a mini-pci card and you can find some more information here:

    http://www.thinkwiki.org/wiki/IBM_Hi...ter_with_Modem

    On this page, it say that it should work with the orinoco driver...

    I had Linux Mint on this one before the Kubuntu installation, and wireless was working (One year old Mint).

    Is this a known problem? I have tried to find a solution to it, but nobody seems to have an exact way of handling it...

    I do NOT need WPA - for the purpose of this laptop, WEP is good enough.

    Tried installing wicd as I never have gotten the Kubuntu/KDE network configuration to work, but still no luck. I know the wireless network is running (can detect it from a different laptop), the card registers in the system as eth1. The card does not come up as disabled, there is just no detection of networks.

    As far as I can tell, it is using the orinoco driver.

    Any tip on how to fix this?

    And yes, Kubuntu 10.04 actually works ok on this old P3 - 1.2 GHz laptop! :-) It will only be used for some light internet access by guests, no gaming or playing video.

    I believe that unlike earlier versions installing wicd does not remove all the previous networkmanager components so you will need to trawl through synaptic for them.

      If what Liquidator recommends doesn't help you'll need to post the output from

      ifconfig

      and if that lists a wireless port (connected or not) then

      iwlist (whatever port) scanning

          Re: Wireless not working after clean install

          Did a general scan:

          Code:
          iwlist scan
lo    Interface doesn't support scanning.

eth0   Interface doesn't support scanning.

irda0   Interface doesn't support scanning.

eth1   No scan results
          Not sure what to make of it...

            Re: Wireless not working after clean install

            Just to make sure I have added all info:

            I had a look at this thread yesterday

            http://ubuntuforums.org/showthread.php?t=505920

            and tried the following series:

            Code:
            $ sudo modprobe -r orinoco_pci
$ sudo modprobe -r hostap_pci
$ sudo modprobe -r prism2_pci
$ sudo modprobe orinoco_pci

              A wireless port is not listed in that output of ifconfig, so your wireless device is not recognized.

              Code:
              lspci
.....
[b]02:02.0 Network controller: Intersil Corporation Prism 2.5 Wavelan chipset (rev 01)[/b]
02:08.0 Ethernet controller: Intel Corporation 82801CAM (ICH3) PRO/100 VE (LOM) Ethernet Controller (rev 41)
              lspci reads both your prism wireless chip and your ethernet chip bios outputs.

              The http://wireless.kernel.org/en/users/Devices/PCI page lists the following for the Prism 2.5 chip:
              orinoco Intersil Prism 2.5 0x1260 0x3873

              which leads you to this site: http://wireless.kernel.org/en/users/Drivers/orinoco

              Intersil Prism 2.5 orinoco_pci 0x1260 0x3873

              and the driver should be orinoco_pci, but going down farther you see this
              Note that support for Intersil (Prism) devices is being disabled from v2.6.35. The hostap driver should be more capable for these cards.
              So, your Prism 2.5 chip should work with the hostap.ko kernel module:

              sudo modprobe hostap

              Before you do that I'd "rmmod" all of the other wireless drivers you modprobed before and reboot.

              IF hostap works for your chip and you get a connection you can make it permanent by issuing

              sudo depmod -a

                And now the wireless is gone from the list in wicd. One step back and one step forward? :-)

                So what should I try next.

                  Re: Wireless not working after clean install

                  A wireless device getting configured as "eth1" is something I've seen, on rare occasions, when a wireless driver doesn't work or only partially works. I've never gotten an "eth1" wireless to work. Finding the right driver will result in an "wlan0", or "ath0" or some such designation.


                  I'm assuming that you followed the steps in my last msg by cleaning up your system and using only hostap.ko.
                  Unfortunately, it seems that contrary to the wireless.kernel.org page that driver doesn't work for your chip under the kernel you are using.



                  One solution found was, edited to fit your situation:
                  $ sudo rmmod prism2 prism2_pci hostap hostap_pci orinoco_pci orinoco hermes (or what ever was modprobed before. You can use lsmod to check and make sure all wireless drivers are removed.)

                  In /etc/modprobe.d/blacklist.conf add, as root, the following lines:

                  # This makes sure only orinoco_pci gets loaded for the prism2.5 card
                  blacklist prism2
                  blacklist prism2_pci
                  blacklist hostap
                  blacklist hostap_pci

                  Add to that list any wireless drivers you had to remove after examining the lsmod output.

                  reboot
                  $ sudo modprobe orinoco_pci (which becomes the only wireless module)
                  This makes sure only the orinoco drivers are loaded and there are no conflicts over the hardware, so everything works at boot.


                  As before, if it works use "sudo depmod -a" to make it permanent.

                  If it doesn't replace orinoco_pci with hostap_pci and repeat the process. One of the should work.
