 |
|
Hi,
I recently had problems getting my wlan card to work after a system update (it used to work before that).
I'm using the ndiswrapper to get the card to work. Now, when I tried to start /etc/init.d/net.wlan0 (which is a link to /etc/init.d/net.eth0), the following happened:
| Quote: |
shifty ~ # /etc/init.d/net.wlan0 start
* Starting wlan0
* Configuring wireless network for wlan0
* Couldn't associate with any access points on wlan0
* Failed to configure wireless for wlan0
|
The output of ifconfig was:
| Quote: |
shifty ~ # ifconfig
lo Protokoll:Lokale Schleife
inet Adresse:127.0.0.1 Maske:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:8 errors:0 dropped:0 overruns:0 frame:0
TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
Kollisionen:0 Sendewarteschlangenlänge:0
RX bytes:400 (400.0 b) TX bytes:400 (400.0 b)
|
i.e., the wlan0 device was down. So the routing table had only one entry:
| Quote: |
shifty ~ # route -n
Kernel IP Routentabelle
Ziel Router Genmask Flags Metric Ref Use Iface
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
|
Even if I loaded the wlan0 device with ifconfig wlan0 up, the routing table wouldn't change and it still wouldn't work.
This, albeit the fact that the card was recognized by the kernel and even actually got a signal from the access point, as you can see:
| Quote: |
shifty ~ # lspci | grep -i network

I searched the internet and found a few people having the same problem (all under Gentoo), but nobody had solved it (or, at least, noone had written anything about a solution).
In short, it looks like everything's right, but the network isn't set up correctly anyways.
The only weird thing I noticed is the following:
| Quote: |
shifty ~ # dmesg | grep ndis
ndiswrapper version 1.2 loaded (preempt=yes,smp=no)
ndiswrapper: driver rt2500 (Ralink Technology, Inc.,06/10/2004, 2.02.06.0000) loaded
ndiswrapper: using irq 10
wlan0: ndiswrapper ethernet device 00:0e:2e:38:f7:36 using driver rt2500, configuration file 1814:0201:1814:2560.5.conf
ndiswrapper (iw_set_tx_power:421): setting tx_power failed (C0010015)
ndiswrapper (set_infra_mode:189): setting operating mode failed (C0010015)
ndiswrapper (iw_set_tx_power:421): setting tx_power failed (C0010015)
|
The "setting tx_power failed" and "setting operating mode failed" didn't occur before.
I tried many different things (like recompile the module, reload the drivers, even different kernel versions etc.), but what finally led me to success was to replace my new after-the-system-update /etc/init.d/net.eth0 with an old one (from another Gentoo machine here).
With the old init script, my wlan card works flawlessly and there are no warnings in dmesg.
So what's up? Is this a bug in the new init script or did I just workaround the actual problem? Anyone has any idea? Should I file a bug report?
For reference, here are the two init scripts, the old one (which works) and the current one (which doesn't work):
http://hetzner.scummunity.de/~malte/gentoo/net.eth0.old
http://hetzner.scummunity.de/~malte/gentoo/net.eth0.new
I'd be grateful for any help. While it works now, I wouldn't like to keep the "old" init script for all eterniy.

Have you recently also updated your baselayout?
In general terms, I had a similar problem with my NICs after a kernel and baselayout update. I had to fall back to older (pre-baselayout changes) to get the network back, until I realized what the changes were.
Search the forum for posts by uberlord. It seems he was a principal in the baselayout changes and his posts were very helpful in learning about what changed and how to make the required changes.
