Ubuntu Networking :: 10.04 Lucid Lynx Network WiFi Slow Speed

May 18, 2010

A lot of people have the problem to find themselves with Lucid Lynx 10.04 and experience massive issues when connecting to wireless - me too. As a service, here some relevant links which promise relief:

[code]...

I tried all of them, and none reliably worked. Every solution which required re-association wtih the AP helped for some time, but nothing helped for long. First, don't let yourself fool by the disable IPv6 trap - while it is "enabled" it is acutally not used by Lucid! I have a clean install of Kubuntu 10.04 on an AMD64 Laptop with Broadcom STA driver: 03:00.0 Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03) However I can reliably stabilize my connection for some time either by manually disabling WiFi with the hardware switch or disabling WiFi by software means and re-activating. This brings speed at par with Kubuntu 9.10 until some time. Can anybody confirm this behaviour?

Ubuntu Networking :: Slow Wifi - But Fast Connection On Network Cable

Jan 22, 2011

I have a strange problem that I cannot diagnose -- slow wifi. About two or three weeks ago, I noticed that my wifi began to slow down dramatically. The problem is the same on my ubuntu laptop and my ipad. But when I connect directly to the router with a network cable, my connection is fine. So it is definitely a problem with the wifi signal itself.

What I have done so far:
(1) I checked all of the MAC addresses connected to my wifi. I identified my tivo box, laptop, and ipad. Nothing else.

(2) I used [I]wifi analyzer[I] on my android phone and selected an unused wifi channel (channel 8).

(3) I changed the username/password on my wifi signal. I also changed the password for my router's admin privileges.

(4) I restarted my router and computer.
None of this helped.

I am using a Netgear WGR614 wireless router.

Ubuntu :: Slow Network Speed When Writing To Server?

Jan 13, 2010

I have just formated and did a fresh install to start all over. I installed Ubuntu 9.1 and everything went fine but the network. The computer serve as a NAS and MediaPlayer. When getting a file from the server, I get a speed of 40-60mb/sec, which are good for a Gigabit network. When I try to put a file in, the speed can't pass more than 1mb/sec and often stop.

Here's the network info:

Code:

vric@XBMC:~$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:24:8c:a1:eb:55
inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::224:8cff:fea1:eb55/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

[code]...

Edit: Looks like it's a Gigabit Problem. I connected the Ubuntu box to my Linksys router which is 10/100 and everything is MUCH faster.

Ubuntu Networking :: Dial-up Networking In Lucid Lynx 10.01 ?

Feb 16, 2011

I've been running 8.04 Hardy since its first release, and was hoping to deal with its loss of support by going to 8.10 but learned that it has already been dropped.

So I'm back to installing 10.04 - and up against the bizarre choice to drop dial-up networking! Fortunately, I have my 8.04 machine still live, and I've researched it extensively without success.

The best summary of what I've done follows this post I found online:

-----QUOTE-----

I read many threads about dialup, including those on this forum; made sure to get an external hw modem [USRobotics 5637 USB, advertised as controller-based and tested to work in Linux], to avoid the softmodem/winmodem problem.

Using the 10.04 LiveCD, I installed the four .deb packages that are in poolmainwwvdial and in poolmainwwvstreams.

Now I'm stuck because I get errors when I try command line stuff, errors like "cannot open /dev/modem" and "can't find /dev/modem in /etc/fstab or /etc/mtab"

I'm confused; I've read so many threads with so much different info that I can't sort it out. Maybe I'm following info that applied to earlier versions of Ubuntu. Every error I try to fix leads to more errors. Can someone suggest a constrained, step-by-step procedure to ensure I've mounted the modem, added myself to whatever groups, and whatever else I need to do?

I know there's no wizard to make it simple, but is there a checklist or something to help me sort this out? I have the ISP info, DNS primary+secondary server numbers, phone numbers, etc. Is there a UI/graphical path, instead of command line? Had no idea this would be so difficult.

Networking :: Lucid Lynx Suddenly Lost Connection ?

Mar 5, 2011

All of a sudden without rhyme or reason, My Lucid Lynx install stopped connecting to my network. This was without any intervention from me as I did not modify install or change anything prior to this happening.

What I have gathered so far is that upon initial boot eth0 seems to always be disabled. So I ifconfig eth0 up to bring it back online. All the settings in the network applet seem to be intact for my manual network that has DHCP disabled. Let me re-iterate that these settings worked fine for months then all of a sudden something went belly up. The same machine will connect fine with the same settings from within Win7.

ifconfig command shows both eth0 and the loopback interface but eth0 never manages to secure the 192.168.1.3 address that it should have. ping 192.168.1.1 returns "Network unreachable" so it appears the connection is being cut off at the machine and not the router. I did check to make sure the connection was even recognized and it sees the wired connection going to the router, but nothing else.

/etc/network/interfaces only shows two lines regarding the loopback interface and nothing else; eth0 seems non-existant within this file which I find odd.

General :: Network Speed Is Abysmally Slow While WinXP Is Ok?

Sep 18, 2010

I have a Dell inspiron 640m (1405). I am a reasonably clued in linux user, but I am getting serious networking speed problems. The networking card is an intel 3945ABG When wirelessly connecting with windows XP, everything runs fine and the network connection is fast.

When connecting with any linux distro, the networking speed is abysmally slow, and the connection drops randomly. (the network is recognised and the connection is made however)

Ubuntu Networking :: Headless GNOME VNC Server On Lucid Lynx Desktop ?

May 9, 2010

I had to do quite a lot of digging before I managed to work out how to do this. It turns out to be reasonably straight forward, and so here is my howto all in one place.

Objective: Connect to my Ubuntu (Lucid Lynx) Desktop machine (which does not have a screen or keyboard) using a remote desktop viewer and get my usual GNOME desktop interface. And have the desktop persist while I am not disconnected.

I have recently discovered one niggly issue with some of the keys being messed up. 'm' and 's' in particular? I am looking into it and will update this post when I have resolved it.

The following steps were performed on a freshly installed version of Ubuntu 10.04-desktop. Just for clarity:

Code:

Install a VNC server. There is a choice of servers I chose the "tight" one.

Code:

Setup your VNC password. This password isn't very important as my setup will only allow for connections via SSH, so 123456 is what I used. One can possibly disable it?

Code:

At this point or the first time you run 'vncserver' (I forgot to check) the all important and much discussed ~/.vnc/xstartup file is auto generated. This is the make or break place where you can either get GNOME over VNC or not. My xstartup which required NO changes was:

Code:

Give the VNC server a test, by running it from the command line.

Code:

Try connecting to the VNC server:

Code:

Ok if that all worked then great! It all did for me and my machine was fresh from the CD.

Now we setup the VNC server to run all the time. There are a variety of ways of doing this. Since this howto requires the use of a SSH shell one could quite easily run the vncserver (as we did above to test it) and then disown (haven't tested if this is actually required) commands the first time you connect. This would leave the VNC server running until you used the vncserver --kill command. This would be a suitable approach if you had many different users wanting to have VNC GNOME desktops.

For convenience in a single user setup we can get the VNC server to be started at boot time:

Code:

Make the contents of 'vncserver.user' (credits to some smart guy on some blog out there that I couldn't find again. and then I made a few improvements):

Code:

Ubuntu Networking :: Can't Connect To WPA2-Personal After Update To Lucid Lynx

Jun 24, 2010

I updated to the latest version of Ubuntu and before I could connect to the network "krafft" that is a WPA2-Personal protected network.If I go into Windows and change security to none I can connect with Ubuntu, but not when it's protected.After a bit of time logged in without network a dialogue pops up and looks almost like this :but "Focus" is replaced with "krafft" and the password is something else.I know that the password is right and the network worked perfectly before update.I got an USB wireless network receiver from D-Link and the chipste is ralink rt2870.In the previous Ubuntu distribution you had to write "blacklist rt2800usb" in /etc/modprobe.d/blacklist.conf but it won't work with or without that blacklist.When I updated I saw some message about the network manager(at least I think so) so maybe the problem is in that.

Fedora Networking :: Wireless At Run Level 3 Using Public Wifi With Lynx?

Aug 5, 2009

I have been trying to test the use of X window forwarding over SSH in a cafe. The Cafe's WiFi requires login via a web browser. Using Fedora 11 with Gnome on a Dell Latitude D600 laptop, the wireless works just fine. I am able to use a virtual terminal to ssh to my server at home. NX client/server works also. However, when I change to Run Level 3 on the Laptop in order to use X Window forwarding, wireless networking fails to function. Will wireless networking function at Run Level 3, and if so, how is that accomplished? Also, if I get Wireless to work at Run Level 3, will I be able to login to the free public wifi using Lynx or some other text browser, as I can with IE and Firefox?

Debian Hardware :: Slow Outgoing Network Speed With RTL8111 / 8168B

Sep 18, 2014

I'm experiencing very slow network speeds in one direction (out) on a clean install of debian.

I've tried with different cables on the server, no luck. Also note that the laptop gets full speed to speedtest.net as per my internet subscription (75/75 gbit fiber), so the laptop can be ruled out as a problem since it gets more than 75X performance to the internet compared to the local server.

The main purpose of this server is to be a virtualbox host. I've set up one guest system and ran iperf between the host/guest (bridged network). It gives better numbers, still the host -> guest direction is much slower than it should be:

Ubuntu Networking :: Why Is Internet Speed Is So Slow?

Feb 10, 2010

When using launchpad and the ubuntu daily build website it is very slow. I get 1.2mb/s normally and the speed drops quickly to 0kb/s This is the case from any version of ubuntu that is installed on my laptop.In windows it is no problem, equally there is no problem from a live cd or an install on my external hard disk. Is canonical blacklisting/slow listing my ip?

I am behind a university network but am sure this problem occurs at home .I did a clean install and had no problem until about an hour ago. When I tried to re download a project using bzr my speed instantly ropped.I had downloaded it fine a couple of hours ago. I hope that someone can shine some light on this, its very hard to work on projects if I can't download them.

Ubuntu Networking :: 10.10 - Very Slow Wireless Speed

Mar 28, 2011

I have very suboptimal Internet speed in Wifi with Ubuntu. Normally in WIndows 7 I get download speeds up to 800 KB/s and a very fast Wifi experience, but in Ubuntu I get 100KB/s maximum and web page load speed is very extremely slow. Also, pinging to AP often gives very high response times and a lot of lost packages while in Windows they are very low and none packages are lost. I have a Netgear wg111v3 which worked out of box when I installed Ubuntu but always with this problem. It is updated and I've reinstalled Ubuntu many times..

Also I forgot to say that in Ubuntu the connection goes down very often and sometimes will not connect again until I reboot. Again in Windows never happened that.
Motherboard: GA-MA74GM-S2H

Ubuntu Networking :: 8.04 - Wireless Speed Slow / Drop

Jan 15, 2010

I've been using Ubuntu 8.04 for about a year and the wireless has been fine but now it's gone screwy and I can't figure out why. This has happened on my laptop and wife's who uses Ubuntu Hardy also. The speed drops to almost 0 mb/s whenever the signal strength is less than 95%.

It isn't the internet connection as vista (I dual boot) works fine below 95% signal strength. To get the internet speed to be at a level that can load an internet page, I have to within 3 feet of the router!! Both of the laptops don't use ndiswrapper, the internet connected straight away from a fresh install.

Fedora Networking :: VERY Slow Speed - Intel 5300AGN - F12?

Feb 5, 2010

I am experiencing very slow speed with the Intel 5300AGN on a Dell Studio XPS notebook and the iwlagn driver. I'm using Fedora 12 with all the latest updates available. When connecting to a G network with WPA2 security, everything goes fine at "normal" speed. When connecting to a N network with WPA2 security, the download speed falls between 0 k/s and 20 k/s max. The connection speed (as stated by Network Manager and iwconfig) is between 0 kb/s (?) and 11 Mb/s during the same session. I'm can't connect through ssh or download with scp (stalled). Web pages take a lot of time to render.

When connecting to the same N network on Window 7, everything runs fine enough. Every N network I try is the same story. Works fine on windows, badly on F12..
