Demonstrating how
1) how all modules loaded at the same time do not yield a working wlan interface
2) prism2_pci obviously isn't working
3) hostap_pci appears to be working (but is not)
4) orinoco_pci is working

Correction: hostap_pci is working as well. At least to the point that it will successfully ping a host on the internet. But the connection isn't stable and only lasts a few seconds. orinoco_pci also looses the connection easily but lasts a bit longer than hostap_pci fixed in beta1 hwinfo --wlan now only lists two available drivers: orinoco_pci and hostap_pci. And unlike with Alpha 7 the system no longer loads both/all available moduls. Instead just orinoco_pci gets loaded. And works fine (stable - so far). i just noticed a very odd thing! In comment #4 I stated that the problem was gone in Beta 1. Well, that's true if you use the KDE CD (I tried both update and fresh install - both showed the problematic behaviour gone). I then tried an installation with the Gnome CD and there the problem is still there (both hostap_pci and orinoco_pci are loaded together)! You should be able to work around this with "echo blacklist orinoco_pci > /etc/modprobe.d/prism2" (or blacklist hostap_pci if you wish). A general solution is not available yet. *** This bug has been marked as a duplicate of bug 173647 *** |
This is on a Thinkpad R32 (2658 BQG). Built-in wireless device is a prism2 based mini PCI card. Will attach hwinfo later. According to hwinfo, three different kernel modules can be chosen for this card: hostap_pci prism2_pci orinoco_pci Unfortunately all three kernel modules will be loaded on boot. With the result that wlan isn't working: r32:~ # lsmod | grep _pci hostap_pci 56208 0 hostap 106372 1 hostap_pci orinoco_pci 10880 0 orinoco 41748 1 orinoco_pci hermes 11136 2 orinoco_pci,orinoco prism2_pci 68608 0 p80211 32780 1 prism2_pci I have to manually unload these modules and pick the only one that is working on this paticular mini PCI card at this moment (orinoco_pci) r32:~ # rmmod hostap_pci orinoco_pci orinoco prism2_pci r32:~ # modprobe orinoco_pci r32:~ # iwconfig lo no wireless extensions. irda0 no wireless extensions. eth0 no wireless extensions. eth1 IEEE 802.11b ESSID:"" Nickname:"Prism I" Mode:Managed Frequency:2.412 GHz Access Point: None Bit Rate:2 Mb/s Sensitivity:1/3 Retry short limit:8 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=0/92 Signal level=-68 dBm Noise level=-122 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 It isn't the network script that causes the laoding of all these modules (rcnetwork restart after I manually unloaded the unwanted modules does not bring them back) - and YaST2 has configured the wireless device to use the orinoco_pci driver (prism2_pci was preselected but manually overridden). Even then, networkmanager does not work and I have to set essid and call ifup-dhcp for the device manually. But I guess that is another bug.
