ArchLinux on Macbook pro mid 2012 - Internet wifi dilema

bartuka · 2015-05-25 23:37:59

Hello Everyone,

I've been using Arch Linux with i3wm in my machine for the past 20 days and I am really enjoying and learning a lot about everything. I have a real problem with my wifi, I can connect but after some minutes or even hours (sometimes) I need to turn it down and on again because it just stops working. I already searched a lot in the forum and I am getting stuck with this situation.

I am using

 Wicd 1.7.3 (bzr-r933)

but already tried the networkmanager (nm-applet) and it's even worst.

I am posting some informations about my drivers.

lspci -vnn | grep 14e4:

 01:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM57765 Gigabit Ethernet PCIe [14e4:16b4] (rev 10)
	Subsystem: Broadcom Corporation NetXtreme BCM57765 Gigabit Ethernet PCIe [14e4:16b4]
01:00.1 SD Host controller [0805]: Broadcom Corporation BCM57765/57785 SDXC/MMC Card Reader [14e4:16bc] (rev 10) (prog-if 01)
	Subsystem: Broadcom Corporation Device [14e4:0000]
02:00.0 Network controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)

The ip link output is weird for me... the name is kind of messy:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp1s0f0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 68:5b:35:a1:c6:dd brd ff:ff:ff:ff:ff:ff
3: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DORMANT group default qlen 1000
    link/ether a8:86:dd:93:8a:9a brd ff:ff:ff:ff:ff:ff

I tried to use the b43-firmware and b43-legacy but that just worked for a while. I follow the Broadcom Arch wiki page and installed the broadcom-wl. Right now I have the following modules loaded relate to internet connection:

lsmod

Module                  Size      Used by
bcm5974                20480           0   (not sure if related to internet)
wl                          6303744        0 
cfg80211                483328          1 wl  (neither this one)

I also disabled the dhcpcd.service because I read that it may cause some issues.

I imagine that this problem is due to some interferences happening between the packages I have installed to handle the wifi connection. I really need some guidance here.

Thank you guys. This is my first post in here and any Arch community forum, so if there are some wrong formatting above, please point out.
Thx!!

Hello,

I'm no pro, started using Arch recently myself. Not sure about disabling dhcpcd.service. However, you might try blacklisting unneeded modules, more on that in https://wiki.archlinux.org/index.php/Kernel_modules. You may need to blacklist b43 and b43-legacy.

Here's how my /etc/modprobe.d/blacklist.conf looks like:

blacklist bcma-pci-bridge
blacklist ssb
blacklist b43
blacklist brcmsmac
blacklist brcmfmac
blacklist bcma

install bcma-pci-bridge /bin/false
install ssb /bin/false
install b43 /bin/false
install brcmsmac /bin/false
install brcmfmac /bin/false
install bcma /bin/false

Thanks riddle00 for your help. I looked for the blacklist.conf file and it was missing here. I created one similar to yours. I will pay attention for the next couple of hours if the stability of my connection will improve.

thx!

Hello everyone,

Your suggestion did help, I think, but the problem persists.

I've noticed something different right now. As I said I am using the WICD-client to connect to the WIFI, when I connect I have at the bottom of my screen a monitor telling me the percentage of quality of my connection. Let's say it is showing me 70%.

After some time, this number goes to 100% and the internet stops working. Then, I went to the WICD-client and pushed REFRESH. Now, the connection monitor is back to 80% let's suppose and the WIFI works again.

Any thoughts?

Thx!

I am posting this because I am having the same issue and it is an old threat. If anyone has solved this, hopefully a further comment will help generate some interest. Other than the above the only temporary solution I have found is to rescan the wireless options in cmst.

Read https://wiki.archlinux.org/title/Broadcom_wireless and install broadcom-wl, don't use wicd anymore but use something based on wpa_supplicant either wpa_supplicant itself or NetworkManager or so.

Open a new thread if you actually need help with any of this now, don't necrobump: https://wiki.archlinux.org/title/Genera … bumping%22

Closing.
