wifi not working [solved]

stetim94 · 2015-01-20 15:08:11

i installed the latest version of arch (xfce4 + network manager), but i can't get my wifi to work.

i discovered acer aspire 5742g has a broadcom, command:
lspci -vnn | grep 14e4
output:

02:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink BCM57780 Gigabit Ethernet PCIe [14e4:1692] (rev 01)
03:00.0 Network controller [0280]: Broadcom Corporation BCM43225 802.11b/g/n [14e4:4357] (rev 01)

and i decided to use broadcom-wl. which seems to be loaded.

lspci -v produces:

03:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01)
	Subsystem: Foxconn International, Inc. T77H103.00 Wireless Half-size Mini PCIe Card
	Flags: bus master, fast devsel, latency 0, IRQ 17
	Memory at d3800000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: <access denied>
	Kernel driver in use: wl
	Kernel modules: bcma, wl

then in /etc/modprobe.d/nobeep.conf:

blacklist b43legacy
blacklist b43
blacklist ssb
blacklist brcm80211

still no wifi, anybody any ideas? if more code is required let me know, thank you in advance

Why are you trying to use wl with that card? Use b43. Please follow the instructions here then check `ip a` to see if the interface is shown.

downloaded and modprobed b43. still not working. ip a produces:

Not an Installation issue, moving to NC...

What do you mean it's not working? That ip output shows wlp3s0b1, that's your wireless interface. Now you just need to connect to something.

I am running an aspire 5742Z with the same wireless card and I stuck with the open source brcmsmac drivers as default and have had no real problems. I also use xfce4 with network manager. (There is the odd occasion where I don't get a connection on boot and have to reconnect but the drivers are known to be a bit buggy I believe.) I'm a newbie so can't offer much more assistance but have been using arch for a few months on that machine with brcmsmac with no real problem.
This link suggests that the 43225 is supported by brcmsmac.

i ran this command:

sudo pacman -S networkmanager network-manager-applet xfce4-notifyd

then i ran:

systemctl enable NetworkManager
systemctl start NetworkManager

then i tried to connect using the installed widget, but it won't allow me to enter any password (it does find wifi)

i would love to make a print screen, but i haven't installed a thing.

sorry, i had no idea where the question should be, i wasn't sure what the problem was. new to arch.

if any further commands must be run to check if things are working let me know, any help is really appricated.

Try installing gnome-keyring as recommended here?

jasonwryan · 2015-01-20 21:09:59

Before installing a network manager you should connect manually. This will generate error messages at the relevant point if something does fail, and means you will gain a deeper understanding of how networking actually works on your box. The wiki page has all the necessary steps.

installing gnome-kerying worked, thank you so much (all of you)

they said arch had a good community you guys most certainly proved that

thanks once again
