 Posted: Thu Mar 28, 2013 10:48 pm Post subject: [solved] wlan0 disappeared |
 |
|
I always connected the interface wlan0.
I enabled in kernel "Device Drivers > Network device support > Universal TUN/TAP device driver support"
compiled and installed the kernel, rebooted the PC.
I added "openconnect" in USE variable.
ran emerge
| Code: | | emerge -uNDv world && emerge -c |
thereafter disappeared wlan0
I did the reverse process, the problem continues.

Can you provide some outputs? Does the driver use firmware, are you using >=sys-fs/udev-199-r1 where USE="firmware-loader" is optional? Anything in /sys/class/net/*
Are you using new enough udev so that the predictable names could be used instead? Is the emerge of sys-fs/udev saying any warnings about leftover files, or anything else
in the end? It has various checks for possible old conflicting configuration files for example.
Some push to right direction, I hope:
| Code: |
# emerge -pv sys-fs/udev
# rmmod rtl8192se
# modprobe rtl8192se
# dmesg
# ls -l /sys/class/net/*
# udevadm test-builtin net_id /sys/class/net/wlan0 2> /dev/null
# ls -l /etc/udev/rules.d/*

I want to remove everything related to the kernel.
I removed the "/lib64/modules"
remove the "/sys/modules" would be a good idea? |

Err, /proc and /sys gets created by the kernel you are running, don't delete anything there ... no point |

before doing the procedure, updated the gentoo.
I saw that udev was updated.
wlan0 is working again.
thanks |

This was what bit me when I merged world last night, which upgraded udev from 197-r9 to 199-r1. I didn't have the firmware-loader USE flag set before and it didn't matter for udev-197-r8 but certainly did for udev-199-r1. The dmesg command showed me that the firmware for my Intel Ultimate N WiFi Link 5300 wireless controller was not being loaded, and wlan0 was completely absent. Adding firmware-loader to the sys-fs/udev entry in /etc/portage/package.use and rebuilding udev solved the problem.

Nod. The USE="firmware-loader" is enabled by default in the ebuild so only users of USE="-*" should have issues (and that's what the users of -* asked for, to not be handheld at all).
I don't think we can disable it anytime soon, since the kernel firmware loader is only in 3.7'ish, well, properly in 3.8/3.9. So leaving it enabled by default for few years, I hope they
don't completely remove it (I mean the upstream maintainers, not the Gentoo maintainers) |
