BCM4312 802.11b/g LP-PHY

Can someone please help here.

First time trying Zorin and wireless will not work no matter what I've done. Searched a ton of Ubuntu fixes to no avail.

If I turn off the wireless for 20min and turn it back on it will connect and work briefly then lose connection. No other linux devices indicate any issues when connecting to my either of my two routers.


Laptop is Acer Aspire 5516

First of all please advise if you have got internet through an ethernet cable and updated all the packages in synaptics package manager?.
If yes, have you tried enabling the recommended Broadcom Driver in the "additional drivers"?


If you did all above and you did not get any result please read the following:

Your wifi card is BCM4312 LP-PHY. This means that you should go to synaptics package manager and install the following two packages:

b43-fwcutter
firmware-b43-ipphy-installer

(please make sure that no any other package regarding the b43 driver (like firmware-b43-installer or firmware-b43legacy-installer) is installed. Otherwise, uninstall it.

Finally, if you installed the above two packages, I think that you have to de-activate the recommended Broadcom driver in the additional drivers section.

Give that a try, reboot and let us know.
Otherwise please post the results of
Code:
lspci


and

Code:
dmesg

Can you please tell me first of all what did you do, step by step?

Also, regarding dmesg, try to locate the lines indicating the error of your broadcom card.

Ps. Always insert the outcome of terminal lines in <code>.

hi,

open network settings and then edit and highlight the wifi connection you wish to edit, make sure it says "Connect Automatically" and "All Users".

Regards Wolfman :D

Tried all as advised and wifi still keeps dropping.

The only way to get it to connect again is to turn off wifi, wait 5 min and turn it back on then it will connect automatically again. As soon as I try to use internet it drops.

Lan works fine and I can see SSID of in wifi. It just won't stay connected.

What I've done so far is:


Removed the additional driver and installed b43-fwcutter and firmware-b43-ipphy-installer

I then open network settings and then edit and highlight the wifi connection you wish to edit, make sure it says "Connect Automatically" and "All Users".

Then tried https://www.ultimateeditionoz.com/forum ... 259&t=2860

I have WEP mixed mode enabled on one router and 802.11n on the other router.

I tried killing WEP and the connection still drops.

Hi Zaphon,

try deleting any wifi connections you have listed in the wifi network manager and manually create a connection, make sure that your WEP ID and password are correct to the letter!!.

Try also this.

Go to synaptics and uninstall all the b43 related packages. (i.e. b43fwcutter, firmware-b43-ipphy-installer etc etc).

Then activate only the recomended STA broadcom driver from additional drivers and restart.

PS: Is your system updated? Which kernel are you using?

The recommended additional sta driver was what I originally started with that and the wifi was dropping. Across the board the wifi keeps dropping only on the acer 5516 laptop

Could you please post the results of
Code:
nm-tool

Hi,

go here and check for driver support:

http://linuxwireless.org/en/users/Devices

and/or, use the Windows Wireless driver tool assuming you have the Windows driver CD available!!.

Wolfman, since his card is BCM4312 LP-PHY the suggested drivers are b43-fwcutter and firmware-b43-ipphy-installer (and disable the STA driver).

Supposing that the above is true and ZaPHoN has done same (this is why I asked for the results of nm-tool to see if the correct driver is loaded), I have made an investigation and at some laptops there seems to be some problems with the lp-phy broadcom cards, and you get disconnections.

My next suggestion was going to be ZaPHoN to try to connect again, and when he gets a disconnection to open a terminal and write

Code:
modprobe b43


Let me know what happened, i.e. if you got connected again.


There is a possibility that you will have to disable Qos. To do this, open terminal and write the following, one by one:

Code:
modprobe -r b43
echo options b43 pio=1 qos=0 >> /etc/modprobe.d/local.conf
modprobe b43


And let us know if this helped at all.

First time trying Zorin and wireless will not work no matter what I've done. Searched a ton of Ubuntu fixes to no avail.

If I turn off the wireless for 20min and turn it back on it will connect and work briefly then lose connection. No other linux devices indicate any issues when connecting to my either of my two routers.

I notice that on the Wireless Interface your logical name is eth1 mine is wlan0 as I've underlined.. Why I don't know. But my wireless connected first time no problem straight out the box. This is one of the reasons I installed Zorin and its been rock solid ever since.
You seem to have 2 eth connections I have 1 eth and 1 wlan

Hope this helps cheers Aldyin.

Swarf, having said that, there is also the solution of using ndiswraper (windows wireless drivers) and see if wifi can be more stable in this way.

ZaPHoN

Thu Feb 16, 2012 8:43:20 pm

Oh man this is turning out to be a nightmare..

And I though Acer was linux friendly.

I removed

b43-fwcutter
firmware-b43-ipphy-installer

Rebooted

used ndiswraper to install L1C62x64.inf for 8131 LAN_Atheros(AR8131)_v1.0.0.10_Win7x82x64

Rebooted and now the wifi on/off switch doesn't work and no wifi at all.

I am so sorry that this turns out to be so difficult.

I have searched various pages in the web for this problem. I read somewere that someone managed to get it working by installing the bcmwl-kernel-source package from synaptics.

As regards the ndiswraper, maybe you need a different .inf file.

Go to the Acer support web page, and with your exact laptop model download the XP and win2000 drivers for your wireless card.
Try both .inf files from the drivers.

Just to let you know, today I have installed Zorin 5.2 core in a 32GB usb stick. The wireless card of the laptop I am using with this USB stick is BCM4312 LP-PHY.
I just updated the packages from synaptics, the broadcom STA driver appeared in additional drivers, I enabled it and rebooted. After the reboot my wireless network was fully working...

Simple as that.
