 |
|
This one throws me. After a kernel update, my wireless networked ceased functioning. After trying more than a few things, I tracked down that my external wireless module (ipw2200) was conflicting with the new kernel module. emerge -C ipw2200, rebuild the kernel, restart, and no more error.
It seems that the card is working. I can scan the area and pick up all the hotspots I expect. I can open wifi-radar and associate with my network. I can even get an IP. Once I unplug the hardline ethernet and try to rely on the wireless, it's like I'm not connected to anything at all.
To make this more confusing, I pinged both addresses (hardline and wireless) from another box. Once the hardline is disconnected, *both* go dead. Wierd! |

| That's probably because the default route is on the wired connection. Advice: Use wired or wireless, not both. |

You could try re remove the module and modprobe again it

I have the same problem than you and it's so confuding. When laptop starts i have both devices up, working with wired eth0 and i can ping both. Then if i stop eth0, the wireless eth1 remain up but i can't ping it. The if i put up again eth0 things remains equal. Not ping at any devices, but if i put down eth1 then eth0 starts working fine. Any idea?
The only warning i have when i try to put eth1 up is:
| Code: | Warning: Driver for device eth1 has been compiled with version 22
of Wireless Extension, while this program supports up to version 20.
Some things may be broken...

Some config outputs:
