Thread: Wifi does not work on 11.0

  1. #1

    Thumbs down Wifi does not work on 11.0

    When I switched to 11.0 I got the problem with my wireless card.
    I am using D-Link DWL-G122 ver B1 usb dongle (kernel module: rt2500usb)
    I use WPA-PSK encryption in my network

    Everything worked well on 10.3 out of the box, but on 11.0 i got some problems.
    First of all, I can scan for wireless networks and connect to them (via updated knetworkmanager). But when it comes to usage - the behavior is rather starnge. Here is an output of ping command. This is a single output (not a mix of different ones)

    Code:
    kolyanoid@linuxclient:~> ping 192.168.100.100
    PING 192.168.100.100 (192.168.100.100) 56(84) bytes of data.

    64 bytes from 192.168.100.100: icmp_seq=30 ttl=64 time=1.04 ms
    As you can see, it is pretty weird.

    I tried using both - yast configuration and knetworkmanager.

    I dont, actually, have opportunity to check other encryption methods, rather than wpa-psk.

    The question is - what's the reason for that? And how shall I make my D'link dongle work in my network?

    P.S.
    The network is working OK. The 192.168.100.100 - is 100% reachable from other PCs (it is my personal gateway\server)

    the Dlink dongle connects to my AP router (not PC)

    Tried installing ralink-firmware and rt2500-cvs-kmp-default packages, but with them the usb dongle did not work - no indication lights worked (but I could scan the air for wireless lan, as far as I remember).

    I don't see a thread behind this request.

    Please do the following:

    If you have a PCI device, issue the command '/sbin/lspci -v' and post the
    information regarding the wireless card.

    If your device is USB, the command '/sbin/lsusb -v' and post the info.

    Once we know what kind of device you have, then we can proceed.

    Thanks for reply!

    As I mentioned, this is a USB dongle. Here is the output for /usr/sbin/lsusb

    Your device is handled by rt2500usb.ko, but that driver is not found in the
    2.6.25.5... kernel that came on the CD and/or DVD. It is in the 2.6.25.9...
    kernel. You need to upgrade the kernel using YaST's "Online Upgrade". For me,
    the automatic upgrade did not install the new kernel. After you upgrade and
    reboot, you should be able to configure your wifi.

    No, this didn't work...

    As I mentioned before, I can scan for wireless networks and even connect to them.

    I set some "experiments" on it and found out, that my wifi works more stable when I get the my D'link dongle closer to the AP. In terms of wifi the change is not significant. Usually I use it on distance of 4 meters from the AP (AP is behind a single wall). I moved it to 3 meters and the things got better (strange). The knetworkmanager started to show almost 100% signal. When it is so, the connection works OK - I can access the internet and intranet.

    From 4 meter distance the signal is shown as approx. 50% strength. In this case the connection is absolutely unstable. Here is another ping output:

    The kernel update has not not changed a thing. To tell uou the truth, I got this problem since the first OpenSUSE 11 betas were released.
    Again, in 10.3 everything works fine!

    And there was no problem in configuration - I always could configure with yast or knetworkmanager. Yast always suggested the rt2500usb kernel module for this device, which is OK. That did not depend on kernel version.

    PS.
    I don't want to use ndiswrapper, if there is some other better way...
    I used it on 10.0 - there was no other way...

    Trouble is your original post doesn't show up in this group
    (opensuse.org.help.network-internet.wireless). The thread starts
    here only with your posting dated Sat, 12 Jul 2008 12:56:03 GMT.
    Looks like your previous postings went somewhere else, so the
    readers of this group cannot know what you mentioned in them.
    Perhaps it would be best to re-post that information.

    That's pretty strange, as I see it with no problems... Anyway, here it is reposted:

    Wireless support (at least as far as cards with rt2500 and rt61 chipsets) is totally broken in OpenSUSE 11.0 and just about every other distro using kernel versions newer than 2.6.22. The move to a "new" wireless driver infrastructure was an absolute disaster, but the upstream Linux kernel maintainers are unwilling to admit it and fix their mistake. Until they do so, I'm sticking with 10.3 (and its 2.6.22 kernel that actually WORKS)

    It's probably one of those web vs. NNTP access glitches.
