 |
|
I'm totally noob in wifi field so need a help to get wifi card working
It is a PCI card
| Code: | 01:06.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
Subsystem: ASUSTeK Computer Inc. WL-138G v2 / WL-138gE / WL-100gE |
What I did till now:
SInce kernel has it's own driver for this card, I enabled wifi stuffs in kernel config, built brcmsmac module and loaded it with modprobe, but ifconfig -a doesn't show wireless interface.
I thought it may be module issue and went in other way (following gentoo wiki): emerged sys-firmware/b43-firmware. Though I expected b43 module will built, I can't found it. modprobe says that module not found. But I found brcmutil.ko module and assumed it is a module built by emerge. I modprobed it, but still ifconfig doesn't show wireless interface.
Is it a module issue or is it just broked hardware? |

Somehow getting my card starting. The next trouble is that it can't find any access point.
| Code: | # ip link set wlan0 up
# iw dev wlan0 link
Not connected
# iw dev wlan0 scan
# |
shows nothing. Though I'm pretty sure there are 5 or 6 wifi access points around.
Have I to do some additional configurations except wpa_supplicant.conf and /etc/conf.d/net ? |

Maybe your wifi is blocked by rfkill. Does your computer have a wifi button or switch?
rfkill can be managed using the controls in /sys/class/rfkill/* or by installing the rfkill package. |

It's a PCI card wifi, so no any switches or buttons.
Interface started by 'ip link set wlan0 up' and it's state is UP.
I installed rfkill to check for blockage:
| Code: | server ~ # rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no |
Seems not blocked, but can't locate any access point |

| It turns out wifi scans for AP, but in some strange manner. At first run iw shows nothing, but it recognizes APs if command was running once more immediately. After a some timeout I have to run iw twice again to get output. Looks like card sleeps by default and first scan command awakes it up. Next scan collects AP info. After a while it sleeps again. Hmm. |
