 |
|
Hello everyone,
after the last emerge world, and getting rid of systemd, I seem to screwed up my wireless or there was something in the upgrade that did that job for me.
In short - here is the snippet from dmesg
| Code: | [ 27.709386] Intel(R) Wireless WiFi driver for Linux, in-tree:d
[ 27.709394] Copyright(c) 2003- 2014 Intel Corporation

[ 27.749386] systemd-udevd[4569]: renamed network interface wlan0 to wlp3s0 |
trying to bring up the wlp3s0 interface with ifconfig outputs a 'rf-kill' error. trying to bring up the device with rf-kill immediately brings the device down - while staring at the wi-fi led there is a very very short blink - and the wireless interface is literally stuck with 'soft block' - Intel Centrino Ultimate-N 6300.
| Code: | rfkill list
0: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
|
There is another issue that I'll be happy to submit a but report for if someone shares the guide/steps to do so-
[ 728.753962] wpa_supplicant[4001]: segfault at 0 ip 0000000000475299 sp 00007fff0afb6f80 error 4 in wpa_supplicant[400000+ea000]
- wpa_supplicant segfaults after the first time i execute rfkill unblock wifi
I am out of options and out of wireless for the past 2 weeks. I'm open to any opinions/suggestions.

Thanks for the reply,
I started disabling a couple of services one by one, udev was one of them - just for the heck of it.
When I disabled DBus, I noticed a couple other services that were disabled and connman was one of them. I don't recall installing that ever, but a dependency pulled it.
I tried to reenable the wireless again and guess what - it worked.
I rebooted my box and tried again - the same issue. After unmerging connman, miraculously my wifi started working again without being 'soft-block'ed. |
