BCM4360 & bcmwl-kernel-source cause high cpu use

April 8, 2015, 10:39 am

Hi I have no issues with installing the software and getting my wifi running. What my problems is, when I use the driver my system grinds to a halt for 2-5 seconds every 2-5 seconds making the system unusable. This only occurs while wifi is running. I do a fresh install of 14.04.2 x64 and first thing I do is install bcmwl-kernel-source so I can untether my phone and use wifi.

As soon as the driver is making use of the hardware, the lags begin. Xorg, kworker, migration and even network manager tasks will show intermittent high cpu use (30-70%) while the lags are taking place. I am using an ASUS PCE-AC68 wifi card.

Has anyone run into this before or know how to solve the issue of high CPU use while using bcmwl-kernel driver for the BCM4360?

Okay Some friends suggested me to install the r8168 Realtek driver for Ubuntu 14.04 instead of the r8169 (which I previously did).
During the process, I remember executing this command: 'rmmod r8169'. I guess this basically means that my laptop no longer has any wired adapter drivers.
Sadly, the process for installation of the r168 failed, and I am now left with no drivers for the wired connection.
None of the usual commands to detect eth0 (like 'ifconfig -a') are recognizing it, the laptop waits around at bootup for network configuration, and I am frustrated. Any help please?

Hello everyone ive had this Dwa 160 b2 card for a while now.
I have tried countless google searching on and off for a few months but i can't find anything that will resolve my issues.

Here is the output from lsusb

On my labtop it has a built in wifi driver and it is working. But as soon as i plug in my wifi card it freezes the connection.

If someone could please help it would be much appreciated, im sure it would be a quick fix for some.

[ubuntu] Samba Domain Controller with LDAP Backend

≪ Previous: Wifi Card issues

I have followed this guide "http://www.unixmen.com/setup-samba-domain-controller-with-openldap-backend-in-ubuntu-13-04/" to try and set up samba to use ldap as the authentication. I got through the entire guide without error until i try to log into the domain or connect to the share. When trying to connect to the domain from a windows 7 client i get "An Active Directory Domain Controller for the domain "NOETIC" could not be contacted." When trying to map the share I get the error "You might not have permission to use this network resource... A device attached to the system is not functioning. I tried remaking the user account and now I am getting "Access Denied" but that is not my main issue I don't think.

I have tried looking at the SID and making sure that they match where they are supposed to go. It is probably some simple error but I am rather new to Linux and networking.

One thing i noticed in here that confused me was the [NETLOGON] share path. I read that this path should lead to some scripts and also that this path is different for most people. This path I have in my file does not lead to a folder with scripts in it, just an empty folder. I am not sure what this is about.

The SID is not actually all 1's. It is set to the return i get from net getlocalsid. I read other things and saw that some people had to set their domain SID to this SID using net setdomainsid "SID........". I did this so net getdomainsid returns both domain SID and local SID as this same one. I am not positive that this is correct either but it did not seem to create any new errors.

Any help is appreciated. Thank you.

Hello folks,

I am trying to setup a small LAN that consists of a Dell Server and an ASA (the LAN will eventually touch the interwebs). I have ubuntu server 14.04 loaded on the server.

I have the server connected to the ASA via serial so i can configure it through telnet (the shell) - but i am at a loss on where to start.

≪ Previous: Setting up LAN

Hi all,

I have a Synology NAS, DS210j, with network name "hNAS", installed in the same LAN with a Celeron J1900 Tiny Computer.
Ubuntu Mate 14.10 is installed in that Tiny Computer.

After some setup in DS210j, Ubuntu can see "hNAS"
-> by double click on the icon of "hNAS", I can login into my hNAS user account, double click one of the folders, e.g. "mfy_sa"
-> mfy_sa will be mounted and an icon of it is placed on the desktop of Ubuntu Mate
-> however after reboot, mfy_sa disappears.

So my question is:
How to setup Ubuntu so that "mfy_sa" will be mounted automatically after boot up?

Thanks for any kind of help!

Help, help help.....I upgraded to 14.04 a few days ago, and reset my wifi to use Wicd, as I had been doing in the past. I can connect to the internet with no problem, but my entire computer is running slowly, freezing and you tube videos are choppy and laggy. Although I've been with Ubuntu for a while, I am unfamiliar with coding, etc. When running top and System Monitor, I see that my CPU usage is 100% at all times, whether on the internet or not, and that wpa_supplicant is using 70% or more of that usage at all times. My computer is almost unusable because of this. I have tried researching this on the internet, but, to be honest, do not understand much of what I am reading. My laptop is fairly old and my graphics card is an AMD/ATI RS482M which is no longer supported by AMD and has no proprietary drivers. I need to sort this out, and wonder if there is an alternative to wpa_supplicant, if the fact that I am using Wicd rather than Network Manager is presenting a problem, or how to remedy this. Hopefully someone here has the answer to this, as I am totally frustrated. Thanks!

I just installed xubuntu. I'm using a VPN on my host machine. I can't connect to the internet. I tried pinging a public IP address with no luck. I have stopped and restarted networking.

Redirecting traffic sent to a specific IP to a different IP

April 9, 2015, 9:06 am

≪ Previous: Can't connect to the internet

Hello all, I'm trying to redirect port 80 traffic from a virtual machine running on a host box with Ubuntu 12.04 to a different IP. Essentially, the host box is acting as the router in this situation, and is for all intents and purposes I'm trying to do exactly what was done in this thread: http://ubuntuforums.org/showthread.php?t=1786334

I've followed this guide http://www.debuntu.org/how-to-redire...sing-iptables/, which is exactly what is given in the aforementioned thread, however I'm able to see via tcpdump that my packets are still being sent to the original IP, rather than the IP I've specified that it be redirected to.

Here is my nat table:

Code:

~# iptables -t nat -L

Chain PREROUTING (policy ACCEPT)

target     prot opt source               destination         

DNAT       tcp  --  anywhere             69.28.95.246         tcp dpt:http to:104.219.53.230:80





Chain INPUT (policy ACCEPT)

target     prot opt source               destination         





Chain OUTPUT (policy ACCEPT)

target     prot opt source               destination         





Chain POSTROUTING (policy ACCEPT)

target     prot opt source               destination         

MASQUERADE  all  --  anywhere             anywhere

also:

Code:

~# sysctl net.ipv4.ip_forward

net.ipv4.ip_forward = 1

You can see, I'm trying to redirect connections going to port 80 on 69.28.95.246 to port 80 on 104.219.53.230...everything I've read tells me that I've set this up correctly, yet tcpdump shows me that this is not the case. Wanted to bounce this off you guys to see if anyone had any ideas.

Hi!
I'm really hoping you guys will help me in solving this since it's setting me back on my Python studying program I made myself.
I've tried using wired connection but now I don't the option to get a wired connection (like 0 chance).

I've got an acer E1572G running windows 64bit and using a qualcomm atheros 956x.

here's an lshw -C network

≪ Previous: Backing up Win machines onto Ubuntu

I have hostapd and isc-dhcp-server working on my linux 14.04 box. My WiFi devices can find the hotspot and are assigned an ipaddress. At this point there is no connection through to eth0.

I also have a nodejs servers on localhost port 23 and port 80. How do I get all requests coming in on the WiFi to be sent to localhost. My network will all be local and not connected to the www. I assume it's an item in /etc/dhcp/dhcpd.conf but I'm not up to speed with subnet mask configuration.

If I wanted to allow certain domain requests to be forwarded to the outside world over eth0 how would that be done? I know that some WiFi Routers throw up a local html page to get people to log in before they can get access to www. How is that accomplished?

Maybe you know where I should look for help?

With my new Alfa AWUS036NHV USB Wifi using Win-10, I generally shut off the PCI wifi switch on the side of the laptop, in order to use the Alfa USB wifi radio.
In other words, it's an either-or when using the wifi in Windows.

Ubuntu 14.04 problem: I installed Alfa's drivers for Linux, but now, the Alfa USB wifi will only work if the PCI wifi is ALSO activated!
If I shut off the wifi switch on the laptop, then the Alfa USB is ALSO deactivated!

So which one am I actually using in Ubuntu when my Alfa USB is plugged in?
And how can I get the Alfa USB radio to work in Ubuntu, when the laptop's own wifi is shut off, either thru software or the external switch?

I just installed 14.04 LTS and am having issues with DNS and connecting to the Internet. I can ping, I can go to google using IP (216.58.216.196), the same with other sites using IP address.

After setting up my static IP through network manager didn't work I looked around on the net for solutions, nothing has worked.

I've tried editing /etc/network/interfaces

Code:

auto eth0

iface eth0 inet static

address 10.0.0.89

netmask 255.255.255.0

gateway 10.0.01

dns-nameservers 162.253.119.65 162.253.108.30

I also tried editing /etc/resolv.conf

Code:

#Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)

#        DO NOT EDIT THIS FILE BY HAND - - YOUR CHANGES WILL BE OVERWRITTEN

nameserver 162.253.119.65

nameserver 162.253.108.30

I've tried restarting the system and I still can't get to the Internet. Every other computer on my home network works (Windows and Linux) so I know the settings are correct.

Any help would be appreciated before I switch to another OS.

[ubuntu] Ubuntu 15.04 Ethernet interface not appearing

≪ Previous: [ubuntu] DNS issue with static IP in 14.04 LTS

All of a sudden Ethernet stopped working. Originally the network dropdown in the panel said

Code:

Ethernet Networks

Ethernet Connection 1

Disconnect

with all three lines grayed out and unselectable.

Well, I started with the turn it off and back on again, and that did nothing. After searching and performing most of what I could find on the forums, still nothing.

Command outputs:

Code:

Originally:

Code:

paul@serenity:~$ cat /etc/network/interfaces# interfaces(5) file used by ifup(8) and ifdown(8)

auto lo

iface lo inet loopback

But at the advice of the forums I edited and it is now:

Code:

paul@serenity:~$ cat /etc/network/interfaces# interfaces(5) file used by ifup(8) and ifdown(8)

auto lo

iface lo inet loopback



auto eth0
