Slow internet with RTL8723AE

$
0
0
Hi,

I have been trying to configure my wifi card, and I found a few threads on this, but somehow the things I've tried haven't worked (these include compiling drivers from several repositories and trying them). I tried to find the definitive RTL8723AE thread, but couldn't find it. Any help would be very appreciated.

Symptoms are: I can connect to Wifi, but the internet is rather slow (~60 kb/s, instead of 5 mb/s I get on a Windows box).

Here is the output of the wireless script.

Code:

Slow wireless connection behind the wall

Hello!


I am having connection problems with Intel Corporation Centrino Ultimate-N 6300 wireless card on my laptop.


When the laptop is near the router, I get full internet speed but when I go behind the 20 cm thick wall (that is about one meter, about three feet total distance) the router is pingable but I cannot connect to its web interface or get internet access to any other website before connection timeout/closed.


Here us the output of ping next to the router
Code:

PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

I have seen similar issues on other forums. But their suggestions like setting the regulatory domain to correct frequency or following the instructions http://www.linksys.com/us/support-ar...icleNum=135766 didn't help.


This is likely driver issue, I think, but I am not sure what to do with it. Here is some noteworthy details, hope you can help me with.
Please note that the output is from Gentoo but I can reproduce this on Kubuntu as well.

Please notice how late iwlwifi is (not) loaded! It is always about 60 seconds + 60 seconds.


Hopefully syslog messages will be most helpful.

Can you please tell me what else I can check and what can I do with all these?


Thanks very much for your time in advance!

Static IPv6 address sometimes on boot

Hello

I've noticed sometimes the statically configured IPv6 address doesn't get assigned at boot time. I've found some messages in journalctl relating to:
IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready

Any ideas appreciated :)

Thanks

[ubuntu] [zfs] nfs client: cat to changed file ends with not found

$
0
0
Hey all.

We get in trouble since an update from our clients from Ubuntu 12.04 to Ubuntu 14.04.

The behavior:

On client A I change an existing file foo on a nfs share.
On client B I do a cat foo.

1st time after mounting it works. cat shows the content of foo. But if I change foo on client A again and do the cat on B I get the error:
cat: foo: No such file or directory

Doing a `ls` on B resolves the problem and `cat foo` works again showing the new content. But if I change foo on client A again the cat on client B wont work.

Analysis:

If a Program on B does the system call "stat" first, everything works. But if a program like cat directly uses the system call open it will not find the file!

With tcpdump and wireshark I can see that Ubuntu 12.04 calls in the NFS paket under "PUTFH" using the correct (updated) filehandle but in 14.04 the filehandle is wrong (equals the old filehandle. before the change on system A).

Now the very interesting part: If my nfs share on the server site resides on ext4 filesystem and I share it over the /etc/exports, the nfs server answers with the error code NFS4ERR_STALE. The client (B) will do a second request with the correct filehandle and everything works fine. Even on 14.04.

If my nfs share on the server site resides on a ZFS filesystem (ZoL 0.6.4.1, CentOS 7 and Ubuntu 14.04) and I share it over the sharefs option or /etx/exports, the nfs server answers with the error code NFS4ERR_NOENT. The client will fail.

Questions:
1. How can I get the newer clients (14.04+) to update the filehandle correctly like on 12.04
2. (Alternatively) How can I get the server to answer with NFS4ERR_STALE on a ZFS filesystem? Or how should the server answer look like according to the specifications?

L2TP / IPSec VPN Connection

$

I can't for the live of me figure this out. I have been trying for a few hours now to get a L2TP/IPSec connection going but its just not happening.

I am using the standard network-manager in Kubuntu 14.04, I am unsure what additional packages I installed over the past few hours because I have been trying so much.

I enter all the correct info into the L2TP Network-Manager connection window and save the settings, This is the config file it creates:

Code:

[connection]
id=connection
uuid=9a6ff370-0fe0-463a-a08d-442bf9b0b460
type=vpn
permissions=user:muntrue:;

[vpn]
service-type=org.freedesktop.NetworkManager.l2tp
gateway=<my_gateway>
ipsec-psk=<my_shared_key>
user=Mario
ipsec-enabled=yes
password-flags=2

[ipv4]
method=auto

But when I try to start the connection I first get:

Code:

> nmcli con up id vpnconnection
Error: Connection activation failed: no valid VPN secrets.

But when I try it again it will give me:

Code:

> nmcli con up id vpnconnection

** (process:16365): WARNING **: Could not create object for /org/freedesktop/NetworkManager/ActiveConnection/104: Method "GetAll" with signature "s" on interface "org.freedesktop.DBus.Properties" doesn't exist

Error: Connection activation failed: Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/104' failed in libnm-glib.

I am at a loss here and really hope someone has some answers or can point me in the right direction.

Thanks in advance!

creating a fake interface in ubuntu14.10 - Cannot find device "dummy1"

Hi,

I was trying this code in order to create fake interfaces in ubuntu14.10
I need it for bonding

sudo /sbin/modprobe dummy numdummies=3
sudo /sbin/ip link set name eth10 dev dummy0
sudo /sbin/ifconfig eth10 hw ether 00:10:10:ff:ff:ff


sudo /sbin/ip link set name eth11 dev dummy0:1
sudo /sbin/ifconfig eth10 hw ether 00:11:11:ff:ff:ff

while I got eth10 , I couldn't get eth11 , I tried it both with dummy0:1 and dummy1
in both cases the result was the same

Cannot find device "dummy1"
Any ideas?

eth10 seems OK though
ifconfig -a

[lubuntu] Install wifi driver, no wireless after reboot, load driver module and can't connect

$

So i'm running Lubuntu on a macbook pro 13 (2010).

I install the wifi drivers and everything is okay, driver works beautifully.

After rebooting or shutting down the computer the driver won't show any available networks. (There are a ton around here).

So I remove everything using the b43 driver through sudo modprobe -r b43 bcma mac80211 and after a while I do sudo modprobe b43. Everything is okay and the networks show up.

Then when I try to connect the connection fails and when I do dmesg | grep -e wlan0 I get this

Code:

[ 1328.138624] wlan0: authenticate with cc:d5:39:e3:c3:52[ 1328.164562] wlan0: send auth to cc:d5:39:e3:c3:52 (try 1/3)
[ 1328.167437] wlan0: authenticated

[ 1338.177552] wlan0: aborting authentication with cc:d5:39:e3:c3:52 by local choice (Reason: 3=DEAUTH_LEAVING)

And it just does this over and over and over.

My hardware is a broadcom BCM432b (it's based on the BCM4322).

Can anyone help me with this?

Thank you.

[ubuntu] No wireless on HP 15-G261SA laptop

$

0
Well, it's finally happened to me. After many years of Ubuntu-ing, I've bought a laptop that won't give me wireless in Ubuntu! I have wireless when using Windows 8.1, but I stick in my Ubuntu 14.04 live usb and... no wireless. :(

I've done some gooogling, and I haven't yet found a guide. Does anyone know how to make wireless on the HP 15-G261SA? A simple step-by-step guide would be grrreat (I'm no wizard, more like a Mickey Mouse).

Also, how do I discover what wireless chipset my HP 15-G261SA uses? The Windows 8.1 Start screen is a chaotic mix of icons and pictures, no seeming rhyme and reason... I'm afraid I'm really regretting this purchase...

So, any nice ppl wanna help me out? Undying gratitude etc...

Connectify replacement for Linux (hostapd)

I couldn't get hostapd to work.
Code:

sudo /etc/init.d/hostapd start * Starting advanced IEEE 802.11 management hostapd                      [fail]
I might have done something wrong. My device supports AP and I am using connectify in windows. However I was never able to share(repeat/retransmit) my own wifi network. Please help.

Is there a replacement for connectify in Linux?

I am new to the forum, please forgive if am posting in the wrong place.

[ubuntu] lstp client login blank for lstp server on ubuntu 14.04 , what I'm missing here..?

$

0
I am trying to configure a lstp server ( `ip of lstp server : 172.16.40.0` ) on a `64bit ubuntu 14.04` and check it network booting virtualbox vm (harddisk less vm)
I configured everything according to this doc http://ubuntuforums.org/showthread.php?t=2173749


But when I enter root user and password in "virtualbox vm ltsp client", It boots perfect, authenticates perfect.. but not loading desktop.. I mean not loading unity kind of desktop.. just blank..







Here are the things I did while configuring lstp server


First Updated the server


Code:

sudo apt-get update && sudo apt-get upgrade
Then install LTSP, a proxy DHCP server, and a TFTP server:


s
Code:

udo apt-get install ltsp-server dnsmasq tftpd-hpa
Client operating system image built using


Code:

sudo ltsp-build-client --arch i386
Then, to enable support for proxy DHCP by default i ran


Code:

sudo sed -i 's/ipappend 2/ipappend 3/g' /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
and here is my configured `ltsp.conf` at `/etc/dnsmasq.d/ltsp.conf`


Code:

#
    # Dnsmasq running as a proxy DHCP and TFTP server
    #
    # See: http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html
    #
   
    #
    # TFTP
    #
   
    # This might work instead of tftpd-hpa:
    #enable-tftp
    #tftp-root=/var/lib/tftpboot
   
    #
    # DHCP
    #
   
    # DHCP proxy on this network
    dhcp-range=172.16.40.0,proxy
   
    # Tell PXE clients not to use multicast discovery
    # See section 3.2.3.1 in http://tools.ietf.org/html/draft-henry-remote-boot-protocol-00
    dhcp-option=vendor:PXEClient,6,2b
   
    # Better support for old or broken DHCP clients
    dhcp-no-override
   
    # Enable this for better debugging
    #log-dhcp
   
    #
    # PXE
    #
   
    # Note the file paths are relative to our "tftp-root" and that ".0" will be appended
   
    pxe-prompt="Press F8 for boot menu", 3
    pxe-service=x86PC, "Boot from network", /ltsp/i386/pxelinux
    pxe-service=x86PC, "Boot from local hard disk"



Then restarted service `sudo service dnsmasq restart`


**(Tried without `/var/lib/tftpboot/ltsp/i386/lts.conf` and same result of above blank desktop when booting vm client.. )**




Then go ahead and edited, `/var/lib/tftpboot/ltsp/i386/lts.conf`


added


Code:

[Default]
    LDM_DIRECTX = True

then updated image and run the following


Code:

sudo ltsp-update-image


    sudo sed -i 's/ipappend 2/ipappend 3/g' /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

**-----------------------------------------------------------------------------**


Please note: Since they have stated in the above tute " that on Ubuntu 14.04, there is currently a bug with tftpd-hpa" I edited `/etc/init/tftpd-hpa.conf` according to this https://bugs.launchpad.net/ubuntu/+s...09/comments/40


and here is my `/etc/init/tftpd-hpa.conf`




Code:

# tftp-hpa - trivial ftp server

                    echo "Please correct your /etc/default/tftpd-hpa."
                    stop
                    exit 0

            do
                    if [ ! -d "${_DIRECTORY}" ]
                    then
                            echo "${_DIRECTORY} missing, aborting."
                            stop
                            exit 0
                    fi
            done
   
    end script
   
    script
            if [ -f ${DEFAULTS} ]; then

            fi
            exec /usr/sbin/in.tftpd --listen  --user ${TFTP_USERNAME} --address ${TFTP_ADDRESS} ${TFTP_OPTIONS} ${TFTP_DIRECTORY}

Rebooted the server as well , yet I'm stuck with blank screen as above..No matter if I keep it one hour , still its blank... What I'm missing here, ? any help would be greatly appreciated ..

[ubuntu] Shows connection to working wi-fi but stopped connecting to internet

I have been running Ubuntu 12.04 for several years, and it suddenly will not connect to our wireless internet. Firefox says the server was not found, and when I tried installing another browser through the software center, it could not connect to the internet. Other devices are able to connect, so it is not the router's fault.

I don't have an ethernet cable handy, so I'm using another device to troubleshoot.

Here's what I entered so far:

cat /etc/lsb-release; uname -a
lspci -nnk | grep -iA2 net

where to put fake interface commands and startup? which file?

$
0
0
Hi,

I finally succeeded in creating fake interfaces, from command line
it goes like this:
sudo /sbin/modprobe dummy numdummies=5
sudo /sbin/ip link set name eth10 dev dummy0
sudo /sbin/ip link set name eth11 dev dummy1
sudo /sbin/ip link set name eth12 dev dummy2

ifconfig -a confirms that interfaces were created

my problem:
I need this to happen at startup, when the system is coming up
so I followed some guy's advice to put the following line in /etc/modules
dummy numdummies=5 (interface name and parameters)
which was a good advice
only I'm not sure where to put the other lines:
/sbin/ip link set name eth10 dev dummy0
/sbin/ip link set name eth11 dev dummy1
/sbin/ip link set name eth12 dev dummy2

I tried creating a file named /etc/modprobe.d/dummy.conf and place these commands there
only it seemed that this file was never executed at startup...

any ideas?

thanks

[ubuntu] No Wifi After Installing Ubuntu 14.04

After installing Ubuntu 14.04 I tried to get onto my Wifi. But there is no option to do that. Only ethernet cord.
I did research and there's supposed to be options in Additional Drivers in Software & Updates. But all it says is 'No additional Drivers Available.'

I've also read in a few places that my Wifi Card might not be turned on? im just not sure what's wrong

I'm on a Lenovo Edge 15.

Any help would be much appreciated.

[ubuntu] Cant Connect Over Ethernet

I m trying to set up my new pc. I can get WiFi but not wired connection. It uses a Qualcom atheros AR928x wireless card, which also handle ethernet, from what I can work out.

I ve spent ages googling it and read loads of posts but nothing I do seems to work. I ve never had to do this before because I ve always just plugged the cable in and it works.

Also if I plug the cable in when the pc is on it will freeze and I ll have to reboot, which is strange.

Some possibly useful terminal outputs :

EDIT: literally after hitting "start new thread" software updater said I had some updates and one is "DHCP client for automatically obtaining an IP address", maybe this will sort it ? Maybe its as a result of running one of the commands I just ran in the terminal ?

EDIT2: Made no difference, still cant connect.

[ubuntu] Passing VPN Traffic to another interface.

Hi Guys

I have a PPTP Server setup,I followed the instruction here https://help.ubuntu.com/community/PPTPServer
I have 2 NICs on this machine, on eth0 I am connected to my WAN side which allows for the
PPTP clients to dial in.The other interface connects to a switch of an internal network.

I followed the instruction here to have traffic routed between my 2 interfaces http://ubuntuforums.org/showthread.php?t=1905048

My problem is that the VPN clients when connected are not able to access any of the machines on the internal network,connected on eth1.

Please let me know how to achieve this please.

Thanks
Shaun
