Dear Gentoo Users/team,

First I will just say that historically on my gentoo installations I have always used WICD. Now I have need access to wireless N networks and have been advised to use NM.

So NM (and iw) are able to scan and see all available AP's. However I am unable to connect with them I have tried open network as well as normal WPA.
I have tried to connect manually to a open network without success with the follow command. (i not used to iw so I might have done that wrong)
Code:

# iw wlp4s0 connect testap


second problem is whenever
Code:

# iw dev scan

is called either by NM of manually it causes 2-3 seconds of screen flickering. Can I fix that ?

my sys information:
Hardware: Broadcom Corporation BCM4331 802.11a/b/g/n
Driver: Broadcom-sta-6.30.223.30-r1
Kernel: Gentoo-sources-3.9.11-r1
config file: http://bpaste.net/show/118546/

NB: I have followed install note from the Gentoo regarding MBPr (http://wiki.gentoo.org/wiki/Apple_Macbook_Pro_Retina)


Please let me know if there is anyone other system info i can give you in order to help. I would really appreciate any help you are able to provide cause not having proper wireless is making using gentoo impractical . :'(

Regards and Thanks in advance

MacTzu

Hi there,

That wiki article is now out of date. I tried to follow it and found better performance with the in kernel b43 driver, (assuming you too have a BCM4331).

You need to enable the following in the kernel (this is from memory I'll update fully when I'm on the right machine)

In the Drivers section of the kernel config:
Code:

Broadcom BCMA support  -- do this first or the options re unavailable

Networking -> Wireless -> b43 driver  -- you need to enable the HT phy option

then install the b43-firmware package and remove the broadcom-sta.

I've found this to be stable, using wpa_supplicant+dhcpcd as my configuration method.

Hi Telemin & 666,

So I have just tried to move to the B43 drvier as per http://wiki.gentoo.org/wiki/Wifi as also removed the broadcom-sta drivers. But my problems is still the same. I can see networks but I cant connect.
Here is my config file with B43 built in
http://pastebin.com/CgY2xA7Q

Telemin I don't fully understand what you mean but wpa_sup+dhcpcd method could you explain further

Also screen flickering is going to give me a aneurysm, any help with that would earn kisses and hugs.

Regards

NM is another front end for wpa_supplicant, NM is a front end for dhcp too. if you can connect with a static ip, its a dhcp problem. id try static ip, & open unlocked access point first. id make sure wpa_supplicant and dhcpcd are installed, & proper use flags set for networkmanager.

post the output of
Code:

rc-update

Code:

rc-update del dhcpcd default


{{warning|
network manager will not connect if net.* scripts are loaded by rc-update (with exception to net.lo)}}

{{warning|
failure to remove dhcp clients from rc-update will result in a system that will not connect to networks}}

added to wiki. :D hopefully your problems resolved by this, and you can get back to broadcom-sta (if you so choose)
