HP4510S - Wifi problem [solved]

My laptop HP4510s contains 14e4:4315 which is supported from kernel 2.6.32+ [here]. I read also wiki so I decided to use AUR.

I added (b43 !b43legacy) to rc.conf and installed b43-git-tools and b43-newest-firmware.  Reboot and after that I turned on my wifi in BIOS and run Archlinux. Unfortunately my system froze at loding modules.

Now here is the weird thing. My wifi works with WICD, but only with ACPI=OFF.

Another note:
1) Everything boots fine when I edit rc.conf and disable interfaces !eth0 !wlan0, but the catch is that network isn't working. I am a little bit confused, because this is recommended settings in WICD Wiki [disable interfaces].

2) Or when I deleted b43 module from rc.conf, again everything boots fine but wifi isn't working. Is it b43 issue?

Is there a possibility to enable these interfaces after successful boot? Or where is the problem? It has to be in wifi card because when I turn my wifi off in bios everthing works fine.

Where could be the problem? I am so close to have my first perfect linux setup. 2 days ago I was Windows user and I am not going back, I fell in love with Linux .

You can just comment out the whole interfaces array in rc.conf (wlan0 hasn't been declared anyway):

#eth0="dhcp"
#INTERFACES=(eth0 wlan0)

Next I would try to bring up the network manually (ifconfig up), and see if your card can scan for networks (iwlist scanning), to figure out if its a problem with WICD or with the card/acpi/module.

I tried ifconfig up/down and iwlist scan, but nothing. It has to be card/acpi/module problem.

What output do you get from "ifconfig wlan0 up"? Any errors? You can also reload b43 module (rmmod b43/modprobe b43) and check dmesg for errors.

Some quick google finds you may want to look into:

You need to do the following...
#eth0="dhcp"

INTERFACES=(!eth0 !wlan0)

as well. Otherwise wicd won't work. You see, wicd replaces the default method of network use, so you have to disable the default method in your rc.conf.

Re: HP4510S - Wifi problem [solved]

Good news! Problem solved. I removed b43 and used [BCM4312 Wiki Page]. It is working like a charm. I don't know why b43 did'nt work, but I am satisfied Archlinux customer now. Thank you for your time and effort.

This topic actually might help to a lot of people. There are really many desperate 4510's owners out there.

Boot with acpi=off and use [BCM4312 Wiki Page]. That is my solution. B43 didn't work for me.

Just to clarify - acpi=off is not needed once you got the alternative wl driver set up?

Yes, I guess there is bug in B43 module. But I am here for two days so I am not ready to make a detailed report.
