Networking :: Extremely Slow Ethernet Connection On Multiple Distros
Jul 9, 2011
the title says I have painfully slow(connection times out when loading google) ethernet connection on my new pc. This comp had similar problems with the OEM windows 7 install but now it's strictly a linux box so I'm anxious to get it fixed.
I'm running Ubuntu 10.04 and Slackware 13.37, and have wireless working on Ubuntu but haven't set it up on Slack yet. The only thing I've done so far is try to change speed and duplex using ethtool but it didn't work, the settings stayed the same. I'm writing from another comp so I'll do my best to post any info you request but I'll have to use a flash drive lol
I've been troubleshooting this problem for several hours now and I'm out of ideas. My internet connection is fine in Windows 7 but an older computer I resurrected (AMD Athlon 1.7 GHz, 512 MB RAM, Fedora 14 Security Lab Spin) is having the stop-and-go's with its internet connection. It will work for very briefly, then it gets extremely slow, where any page I try to navigate to in Firefox 3.6 takes forever to load.I have a DSL connection and my DSL modem is connected to a Linksys WRT54G2 router. I set up a static IP in Windows but don't know how to do this yet in Fedora 14, and I need to get my internet connection working so I can troubleshoot further, but with it being so slow, I'm having to use Windows to search for problems and then switch over to the Fedora box via KVM (IOGEAR), which I also just started using. I don't think that would be related, but who knows.
I just got my internet working through the wireless card with some help. However, my downloading speeds are beyond extremely slow. While I type on this computer, I am downloading things @ ~500-700kb/s, but when I try to download the package updates etc for my Ubuntu 9.10 laptop, It downloads @ ~ 4k b/s- which is UNBEARABLY slow, putting me at 14h left to complete a 200 mb update. Dell Inspiron 1100. Ubuntu 9.10
my installed windows makes full use of the 32mbit connection. in fedora i get between 10kbit and 100kbit.this is very annoying especially while browsing the net or using the package manager to do updates or download new software. what could be the problem and how could i solve it?
i very much like the look and feel of fedora 15, but this just makes it unusable on a daily basis.
A couple of days ago my internet connections suddenly became very slow/intermittant.
I thought the problem was at my DSL provider but after more checking the problem seems to be in Ubuntu/Linux somewhere.
Reason: I can dual boot with windows 7 and have no ptoblem at all. Also I tried a Ubuntu laptop on the same router ethernet port and it also works fine. So its not my hardware or my provider, and its not a general Ubuntu problem either.
There are no error messages in any of the /var/log files and ifconfig looks normal.
It seems to be a DNS problem as it's the initial connection to a host which often times out. If I get a connection, I can e.g. stream an radio station fine.
If I try to e.g. traceroute any host it times out (no reply).
Ubuntu 10.10 is totally up to date as of today.
I'm stuck! How can I troubleshoot this to find the cause?
so i had Jaunty installed last week with no problem. But then i decided to install winxp, erasing it. I hated it, and reinstalled ubuntu, this time lucid.However, the internet has stopped working properly. I've tried wireless and wired connections and they either dont work or will load half a web page after a few minutes. A good deal of the time the browser will time out or fail to find server.The ethernet is working, so I'm assuming the issue is with a missing driver or the such. I have 10.04 32bit installed on Gateway MD2614u laptop.
I am currently facing a weird problem, It's that the internet connection becomes extremely slow when using static IP instead of DHCP when Im connected through a cable! The local network seems okay with both, but differs when using the internet!
I've ran a ping test and got the following results!
using static IP
Code: $ ping -c 3 google.com PING google.com (209.85.153.104) 56(84) bytes of data. 64 bytes from 209.85.153.104: icmp_seq=1 ttl=42 time=343 ms
[Code].....
When I used static IP i received only one packet while when using DHCP i received all three!! Also I lost 66% of the packets when using the Static IP connection! And most importantly, the speed, DHCP connection was 8 times faster than Static IP connection!
I have an old HP pavilion laptop (2005) that was useless.I installed Ubuntu 10.10 on it and it became a working computer again. It was excellent, snappy, it was as if I had bought a lower end modern laptop.Internet was working great.I did not have any complaints (in fact, I thought that a modern computer running Ubuntu would beat my so adored macbook, speed wise). For some time I had 2 efficient computer, a macbook and the hp with the Ubuntu OS. So on the last weekend of February, my internet got extremely slow on both computers. After that annoying weekend (February 28) the internet on my mac was good again,however, the internet on my linux continued to be messed up.I tried disabling IPv6 on my machine and on firefox, tried the openDNS, the MTU stuff, but nothing.I even formatted my disk and installed ubuntu again (all this using the installation CD).However, apparently the installation CD uses some of your existing configurations (for example, the layout of the close, minimize,maximize:menu buttons on the corner of windows did not go back to default). So I'm guessing whatever was messed up with the computer didn't change back to default or the previous configuration when I first installed ubuntu. To give you an idea of how slow the internet is, installing alien (terminal installation),I got low speeds of around 150B/s (no typo here, it was bites, not kilo bites) and the fastest around 5,000B/s. The fastest I got was downloading chrome at 6kB/s but that didn't last even a minute. So given that these transfer rates are obtained both on firefox and the terminal, I'm assuming it is not a browsing problem.
A thick headed solution, would probably be to install windows again to get the network configuration to "standard" and then install Ubuntu formatting the disk again (using the CD).I'm using ethernet,so,thinking it might be cable problems, I did try to use the cable that was on my mac on the machine with linux. No success there.
I don't know if others are experiencing this but browsing is extremely slow in firefox after "upgrading" to ubuntu 11.04. I have not tried other browsers. Even checking for updates fails several times.
I had to re-boot to windows to post this thread and now it's working fine. It's been 3 days since upgrading and I've observed many times that there's no such problem in windows while I have to wait like 4-5 minutes and refresh many times to open a single page. Some sites like google are quicker though. I use firefox 4.0 both in ubuntu and windows. I didn't have this problem in 10.10 and it took me about 5 hrs. to download 1 GB upgrade packages.
Trying to watch movies between my systems and I'm getting upload speeds of 6.5 kb/s from my system to the one connected to the tv. I'm running Ubuntu on both machines, tried with VLC and XBMC. Both are running wirelessly but I know that this issue is new, I used to get at least a meg a second on LAN.
I just did a fresh install of 10.04 on my system and everything runs perfect and exremely smooth, however the update manager and firefox are taking forever to load (the progress meter reads something like 2d 17hr 23m), however the internet connection is very fast.the logs are all insanely clean with the fewest errors I've ever seen, so this shouldn't be too terribly difficult to solve. Also I seem to be having a problem with the font on Firefox, every fourth letter or so has a bright streak in it. Anyway, that might be related or not but my main concern right now is getting my download speed up to par?
I have several Ubuntu installs, including one on a flash drive. I also have a server. I want to sync my home directories from all my client installs onto my server. What I want is really a combination of two things: Unison, which enables me to work without a network connection. An SFTP filesystem so that changes are immediatly sent to the server, not JUST at login and logout, which makes login and logout extremely slow. Is there any combination I could use? Could I make unison sync extremely frequently?
I just installed a fresh copy of Fedora 11 x64 on my Dell XPS M1530. Last week I purchased a NAS device and backed up my entire Fedora 9 x86 system on it. I have an NFS mount that I'm restoring my data from.
The first thing I noticed after installing is that downloading of very large files (several MB to several GB) over my wired network is extremely slow. What I'm seeing is that it will download 3 - 5MB then pause for several seconds and download another few MB and so on. If I download a lot of small files from the NAS device it works fine and very fast. If I upload large files to the NAS they upload fast. If I boot into Vista and download large files from the NAS it is fast. If I use my wifi card to download large files from the NAS it downloads OK (not too fast but it is wifi so naturally slower).
In Fedora 9 I did not have this issue. I'm not sure if the issue is specific to NFS or if it is will all large files via the ethernet port (I don't have a way to test at the moment). lspci says 09:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8040 PCI-E Fast Ethernet Controller (rev 12). dmesg doesn't indicate any issues.
I have been working with Linux for about 10 years and I have a good understanding of IPv4 networking and routing but not so much detailed knowledge of implementation or specific networking packages.
I have a Linux system running a custom-built (Linux from Scratch) distribution and using 2.6.15 kernel. My system has 4 Ethernet controllers (eth0, eth1, eth2, and eth3). I have intentionally left out support for forwarding/routing of packets as this machine is not intended to be a router and I specifically do not want it to be able to so. My intent for the machine is to function as a server to 4 different and separate networks without allowing traffic or hosts on one LAN to access or adversely affect those on the other LANs.
My main question: is there a way to completely isolate the connections to these LANs and if so, how might I achieve it, and through what packages?
I have been having some issues:
1) Default gateway. With only a single default gateway, network requests from a LAN that is not directly connected to one of the 4 NICs and for which there may not be a static route defined, may send a response to the default gateway which is on one of the LANs connected to a different NIC than the one that I received the initial request on. Is there anyway to isolate outgoing messages to only go out on the NIC that the corresponding request was received through?
2) Default gateways. I have a requirement to allow DHCP on these interfaces. It is possible that the DCHP servers on each of the 4 LANs may provide a default gateway, but I don't see how I can make use of that. I know that there is a way to configure multiple default gateways via the iproute2 package (which is what I am using) but I don't know how to make sure that the correct default gateway is used for requests that were received on a specific interface.
I run F12. Since some days my laptop has become very sluggish. In Mozilla, switching between the tabs takes like seconds instead of fraction of a second. Also minimizing and mximizing windows takes long. Switching between the windows too takes long. Now I can't see the cursor while typing this post. I disabled some services that start at the boot time. I'm posting a list of services that are on in the runlevel 5 as that's the one I use.
Not much else to say. I'd say it takes at least a minute before I get to the login screen. After that it runs fine and most of the previous problems I've had since upgrading have resolved themselves. why it's taking so long to boot up?
Have a little problem/annoyance. I was trying to use a Live CD with Lucid Lynx 10.04 x86 edition and the speed was incredibly slow. I took more than 10 minutes just to start. I noticed the CD drive stopped spinning (or spinning so slow I couldn't hear it) at times, then starting up again. I also noticed multiple i/o error in the logs after it finally booted up. The reason why I think this is a bug and not my drive/cd is simple:
a) The MD5ed the iso and even made two CDs with different burners. I tried older Ubuntu as well as several other Linux distros and the Live CD boot time is much faster (1-2 min). Tried the CD on a way, way older ancient laptop and i booted just fine and much faster.(I will provide any other info if needed).
At work, we use Ubuntu to compile large numbers of C, C++, Java, and AIDL files.My system is a Core i7 Quad-Core with 8GiB of RAM. Prior to this install, it ran Ubuntu 9.10, 32-bit. A basic compile took roughly 45 minutes.I just did a clean install with (x)Ubuntu 10.04 64-bit. After setting up the build environment to allow 32-bit libraries (mobile development), a compile took roughly an hour:15.
I have had an extremely slow startup (upwards of a few minutes) for awhile now, and nothing seems to work to fix it. Regular boot time is far slower than it should be, and the time of logging in to a workable desktop is just really bad. I will log in, and then I will either get a blank desktop screen for awhile or an all black screen until the desktop will fully load with errors from gnome-panel and AWN not starting up automatically.Some of the fixes I have tried:
Disabling floppy from bios
Downgrading gnome keyring
Removing gnome* and gconf* from the home directory
Putting this script in /etc/init.d #!/bin/sh echo "nameserver 0.0.0.0" > /etc/resolv.conf

I have an HP LaserJet 2100M.Printing OpenOffice documents is o.k. no great delay but when I print out from browser pages (html) each page can take up to 10 minutes to print.I don't know how to troubleshoot this.
I downloaded the emulator called pSX so i can play my playstation cds in my computer. on my laptop i have slackware 12.2 installed.
The dependencies for the emulator are: opengl gtk alsa gtkglext libxml
I found the appropriate packages for all of these (with the exception of opengl, I assume that means it's preinstalled, correct me if I'm wrong) and installed them. the emulator runs, at about a quarter the speed it's supposed to. I get no error messages in the terminal, just the huge speed drop. has anybody else gotten this emulator to work fine in slackware?
I have 2 LAN ports. one from the motherboard (on board) and the other from a lan card i bought a few days back. one is use for browsing the net, the other for a media player.
problem is i cant connect to both the eth0 and eth1 at the same time. i have to disconnect one of them to connect to the other. and this really gets irritating as it doesnt always work as flawlessly as it should. what am i doing wrong?
I know this has technically been posted but I think my situation is a bit different. People have been complaining that karmic is slower to boot. But from what I gather, it's only a few seconds extra due to an extra splash screen. I'm running Ubuntu Studio and mine takes like 5 minutes and is showing me 3 splash screens! 2 for regular Ubuntu and 1 for studio, which is the most sluggish of the three.

EDIT: Also, recovering from hibernate takes a few min. Related?
I'm getting horrible (unusable) performance every time swap is accessed. This was compounded by the GEMS leak and a few other memory leaks, but now under normal non-leaky memory usage swapping is still intolerable. For instance swapping out ~300mb when I opened a new program with RAM full resulted in the system nearly freezing up for about 3-5 minutes (however long it took to brew a cup of coffee and come back to the system just finally unfreezing).
I've got Ubuntu Server 10.04 on a fairly beefy box (quad-core xeon 2.67ghz, 2gb ram) Standard mysql-server installed, with many databases.Lately, mysql has been extremely slow and almost non-responsive. Server loads are low.Running mtop reveals many, many processes from the user: debian-sys-maint querying the information_schema table with the exact same query, over and over."Select count(*) from tables where engine = 'innodb'"
This is adversely affecting my database server, and thus my websites which rely on mysql. Every search I've done looking for more information about the debian-sys-maint user shows problems where that users was deleted. The user isn't deleted.
Is there something wrong with the repositories? Update manager is downloading very slow, about 1/10 the normal speed. I am running Lucid, and I have normal speed on everything else.
I'm running windows 7 on my laptop at work (I know, I know, but I have good reasons). In order to at least some of the benefit of Linux, I run Ubuntu in virtualbox. Things pretty much work great, except more often than not, gnome terminal is really sluggish. It seems like a simple program - I can get videos to play fine, why can't I type text. I installed xterm, and it has the same problem.
