Ubuntu Networking :: Slow Internet After Updating To Natty With Wlan-rt73usb?
May 8, 2011
After updating to kubuntu 11.04 natty, I have a problem with my internet-connection. The problem happens when I use VoIP-Software like Skype or Twinkle and also when using ktorrent.
When using the mentioned software, after 30-90 seconds the internet gets very slow. In f.e. skype, I can hear the one I phoned very badly.
I use kubuntu on a desktop-PC with a Linksys USB-Wlan-Stick. Detailed information is below.
Code:
uname -a
Linux pr1-desktop 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

i installed Ubuntu 11.04 Amd64 today (and have tried ubuntu 10.10 in the past and had the exact same issue.).I had this problem with the wifi, as it recognizes the adaptor (tplink321g) but it cant connect to the right speed. This is my only problem with ubuntu now.If anybody else is having the same issue, and most of all if anybody has the solution to it.

I had a dual install of Windows and Ubuntu working for a good week, then I reinstalled Ubuntu, completely wiping the machine. My connection is greatly reduced--updates take hours to install, but internet surfs okay.
Code:
mieum@mieum-1000HE:~$ sudo ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:24:8c:29:5e:4b
inet addr:59.17.55.227 Bcast:59.17.55.255 Mask:255.255.255.224

I installed Fedara 15 yesterday. I was running Fedora 13 before. Since I did the fresh install, my wireless network runs really really slow, i.e. a few KBs every 30 seconds whereas it ran at full speed in F13. I couldn't find the reason for it. I now tried the live-CD for Fedora 14 and it runs at full speed out of the box (whereas F15 is slow even with all updates installed).
Does somebody know a solution?
Laptop: Lenovo X201
Network Card: Ultimate-N 6300
I gathered uname, iwconfig, lspci and dmesg output for both, Fedara 15 and Fedora 14. But as the number of links is limited here in the forum they're all linked here: [URL]

I have set at static ip on eth0:
In have configured the /etc/network/interfaces as:
Code:
auto lo
iface lo inet loopback
auto eth0
[Code]....
However, I experience a slow Internet connection when using wlan.
Is this a routing issue, or have I configured the /etc/network/interfaces config file wrong?
I use Ubuntu 10.04, 2.6.32-22-generic

I just installed ubuntu as my primary OS, but I have the disk with XP on it and I don't want to go back, but I need faster network connectivity. I have a T60p with Intel Gigabit jacked into my Gigabit router which also has my desktop (running XP) and my NAS. If I FTP files from my NAS (or SCP), I get transfer speeds around 250-500 KB/s (which is not very fast). On this same switch, from my XP desktop I get transfer speeds around 12 MB/s. I get the same speeds using my 802.11n card (Atheros) as with the ethernet NIC (250-500 KB/s).The drivers for the ethernet card and the atheros card are e1000e and ath9k respectively.I have disabled IPv6. Since the problem occurs using either interface, I am just going to concentrate on fixing it for the Ethernet interface (since I believe it to be a systemwide problem).
Code:
skinnersbane@albert:~$ sudo ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
[code]....
Clearly my card is running at Gigabit, but why the bad transfer speeds? I am using filezilla for FTP (technically FTPES). I closed every other program. My CPU utilization does seem high and I wonder if this is part of the problem. I had no problems with throughput using either interface in Windows XP just one week ago.

I can connect my wlan card to router (gateway) ,but I can't go to internet, pinging my router (and everything else) also falied. Same problem was with knoppix but with help of others i solved it modifing etc/reslove.conf IP address to my gateway (nameserver). At ubuntu resolve.conf seems ok, as there is already IP address of my gateway?

My problem with UBUNTU is that I can not use acer-wmi because I get this ERROR :
Code:
... so I can not use the acer_wmi . But this is not my only Problem :
It is most likely caused of the missing " Firmware " / Driver for my WLAN Card ( Internal ) . Currently I use Ubuntu 10.10 but I tested 10.04 too before 10.10 and it found my Card but not the Button .
So I want to know if there is any solution for my problem .
If it is important :
I use an Acer eMachines e525 with Windows Vista Home Basic ( Pimped up ) and Wubi . I saw a lot of people with simmilar problems they have it as only boot option .

I recently upgraded from Ubuntu 9.10 to 10.04 (both 64-bit) and my USB WiFi adapter which previously worked fine stopped working. The adapter is a Hama USB stick based on the Ralink rt73 chipset. I've tried using the Ralink drivers that come with 10.04 (both rt2800usb and rt73usb) but neither work. When I use rt2800usb, the adapter is recognized as interface wlan0, however I can't see any wireless networks. When I use rt73usb (and blacklist rt2800usb to avoid conflicts) I no longer have a wlan0 interface and there is no wireless adapter shown in the network manager. I've pasted in the results of lsmod, lsusb, and ifconfig -a (with MAC addresses removed) below.

I dual boot windows xp and ubuntu 10.04 LTS and the wireless card works perfectly fine in xp so I know its not a hardware/network issue. In ubuntu, it detects wireless networks, will connect to network and work for about 20 seconds.
[Code]....
and it continues on after this alternating between a normal 20ms and high ping over 200ms. The connection refuses to load anything off the internet/local network.

I had a conky script which was working OK in Ubuntu 10.10, but I made a fresh install on friday, and when I went to restore my conkyrc, I saw it was not working properly. There is a problem in the calendar, and can't solve it. I've beeing trying it the hole weekend without success. The conky version is the same it was on 10.10 -> conky 1.8.0
let's see the problem : as you can see, the "today" day, is not being showed properly (it also happened yesterday and the day before, not only today) here it is my conkyrc:
Code:

After my system was updated to Natty, even though Software Sources is set for LTS updates only, none of the repositories in Software Sources or /etc/apt/sources.list.d were updated. I have manually updated the Software Sources repositories, and removed the outdated repositories from /etc/apt/sources.list.d, but when I do apt-get update I still see references to previous Ubuntu versions. How do I update ALL the repositories?

I am running ubuntu on the Tegra2-based Toshiba AC100, flashed to the internal eMMC (instructions: [URL]..I really like this machine. In accordance with the instructions linked above, I also have a bootable SD card system (far slower), where I can go in as chroot for my eMMC-flashed system if needed (depending on what people suggest).
Yesterday evening I tried to dist-upgrade to Natty but it stopped during installation/configuration at python2.7-minimal. This package (or python-minimal (default)) seems to be in conflict with a few other packages (unity and some other mystery packages named "ubuntu" something).
I am now at a half-updated system that spits out lots of errors while trying to load the new desktop (X starts, but basically just a purple background). I will try logging in to an alternative DE (LXDE) this evening when I get back from work.

I have a wireless network (192.168.1.0) that's bridged to the Internet and a wired one (192.168.0.0) that's only local. When I am connected to both networks, Natty wants to route my Internet traffic through the wired, local-only one.
Can I make it automatically "just work", so that the right network is chosen for Internet traffic? Otherwise, what's the workaround?

i use a telekom s100 set-top-box, which originally had a prism54 wlan-card. but wlan was very slow. but the driver was working well and it did not seem to be a configuration issue, so i assumed that its that card which is so slow. following i purchased a atheros based wlan-card which is working perfectly well with the ath5k driver of my linux kernel (2.6.26-1-686). but the connection is pretty bad anyway. i get max 300kb/s from pc to pc. as its the same with 3 different cards i tested in the s100 i assume it is a configuration issue? or might there be chipset or mini-pci-slot limitation?
when i check the connection with iwconfig the bitrate is somewhere between 1-54mb/s, rising to 54mb/s and then falls back to 1mb/s, rising to 54mb/s again, falling down, its an infinite loop. im using wpa_supplicant for the connection, but i don't think thats the malefactor. well, you never know .. i tried to set the bitrate with iwconfig wlan0 rate 54M but that ended in a disconnection ...

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.

I'm finding that the internet speed in Ubuntu 10.04 is over twice as slow as the speeds that I am getting in Windows 7.I've tried disabling IPv6 through Grub and Firefox but it didn't really help much.. anything else I can try?Connecting through wireless at 54 Mbps.

I'm staying out at a friend's house in the middle of nowhere, and she's been complaining about how slow her satellite internet has been of late. So I decided I'd take a look. If I ping my server at home, I end up with these statistics:
Code:
// @ 1 ping probe per second
60 packets transmitted, 36 received, 40% packet loss, time 59172ms
rtt min/avg/max/mdev = 639.915/799.882/1209.119/104.763 ms, pipe 2
Compare that to driving 70 down the highway tethered to my cell phone: I see latencies in the 3000's and out-of-order packets, but practically none get dropped. If you ramp it up to 5 ping probes a second, the loss climbs to around 75%. To me, that seems quite excessive. The interesting thing is that all the packet loss seems to be occurring on download traffic - I set up tcpdump to monitor the packets on my server during the ping test, and all but 1 of the pings to got there, so the other 25 lost packets wondered astray on the return trip. I tested it with the client directly connected to the modem (it had the public IP).
So I'm quite certain that it's the satellite link itself that is the issue here. I've attached the complete logs from the ping test for your enjoyment. Of course, TCP corrects for the loss of packets, but with a latency of 800ms, resending packets takes a significant amount of time, not to mention services like DNS that just wait for a timeout to elapse (which is usually way too long). It can take 15 seconds to load a webpage. So I guess my question is, should it be this bad? I know satellite is generally terrible, but I didn't expect to see such rampant packet droppage.

I just installed dual boot Ubuntu 10.04 on my WinXP laptop. The laptop is a Compaq v2552us.
In windows mode, the internet works plenty fast.
In Ubuntu, I can't download a single update for hardware drivers or for ubuntu (it says there are 74 though).
It starts to DL, but max speed is about 800B/s, but that only last for a couple seconds before it switches to unknown. I am connected to my wireless router via cable, can't even get wireless to work (I suspect the aforementioned hardware drivers, which is why I need this to work).

I have 2 computers connected to my linksys router via ethernet cables.
My main computer is running Ubuntu while the other is Xubuntu.
When both comps are on, the internet works fine, but when my second computer is off, my main computer has super slow internet. Sometimes it takes 2 minutes and I get "This webpage is not available", and then I refresh that and it finally loads.
Why does it work when both comps are on? What could cause this?

I've tried out many Debian distros and noticed the ones that I try based on Ubuntu, my USB WiFi adapter works fine and I don't really have any issues. When I try one that is based on current Jessie, I have sporadic WiFi issues and just overall instability with regards to connectivity and audio playback. I have tried two distros based on Jessie and had very similar results on both. Is there anything in particular I can try? I've done everything short of installing Debian stable and just pointing to Jessie. I've done that in a VM so I know I can handle it, but wanted to se if there was anything I should be trying first. I just didn't think a distro based directly on Jessie and Jessie backports would be any different from installing base Jessie as far as compatibility is concerned.

I use Slackware 12.1 and I have a big problem that I can't solve by myself. I'm connecting to a LAN where there are almost 20 PC connected, all with static IP.
my ip: 192.168.1.205
netmask: 255.255.255.0
gateway: 192.168.1.1
DNS server: 80.58.61.250, 80.58.61.254
I configured manually it but it doesn't works well. I set up the DHCP server on Windows 2003 so I tried to configure it with dhcp too. It gives addresses from 192.168.1.200 to 192.168.1.240 there are no PCs connected with DHCP at the moment, so my IP is only mine.
My problem is the following:

It takes a lot of time connecting to a internet web site! It's really strange because downloading a file the transferring rate is good, it takes some time starting, but it works normally.

I set up my linux router as a simple NAT router. I use CentOS 5.4. When I set up ISP proxy IP in the browser of client PC, Internet access is fast. When I remove ISP proxy IP from the browser, Internet access is slow.
ISP use transparent caching but I can use manual caching as well. Clients on my network with transparent caching get slow internet access and using ISP proxy get fast internet access.
ISP announce that we can use transparent caching or manual caching.
So, I set up my linux router with squid. I set up cache_peer TAG point to ISP's proxy IP. But the problem is the same. Using my squid proxy is slow and using ISP proxy directly is fast. All other network settings are correct.
How can I improve my internet connection using transparent caching. I don't want to set up proxy IP address on all clients.

Is karmic is slower for you all: if you're running windows ping a server on windows/ubuntu and compare. 9.10 is consistently slower for me. I've seen enough "slow internet" posts to suspect that someone screwed up bad. Everyone says it's ipv6, but none of the fixes work for me. Pretty sure it's ipv6 (or at least a dns-related problem):

I've been running Ubuntu 10.04 inside Windows 7 (demo version) for 2 weeks or so now and I really loved it. So much so that, last night I decided to burn the boot cd and put a full installation of it on the computer, instead of using Windows 7. After doing so, I started getting some small problems.
First problem was with aMSN, the webcam doesn't work anymore. It used to work when I was using the demo version of Ubuntu, but not anymore. I had to use meebo to get it to work, don't think that's a problem with Ubuntu though.
Secondly, Firefox is running really terribly. Whenever I try to watch a video, it stutters REALLY bad, as if it's maxing out my CPU.
Third, I'm getting an error message whenever I start Google Chrome, it says:
"Your profile could not be opened correctly. Some features may be unavailable. Please check that profile exists and you have permission to read and write its contents."
It plays videos well but half time the audio doesn't work and I have to restart Chrome. (I tried uninstalling and reinstalling through synaptic, but that didn't work, the problem was still there).
Fourth and finally, the internet is just really really slow. Since the moment I installed the full version of Ubuntu it's be REALLY slow. I tried a download through bittorrent and the speeds were terrible, I ran a speed test while downloading (upload was limited to 5 kb/s) and I was still getting speeds of just around 10kb/s. So I closed bittorrent ran a speed test again and I had 1mb download and .75mb upload with 31 ping. I ran the test again and got 42 ping with same download and same upload. While I was downloading, the ping was 309. My normal speed is supposed to be 6mb download and 1mb upload
I guess version 7.0X had internet issues aswell because, when I did a google search for a solution, it turned up several results on how to fix it for 7.0X, which didn't work because the alias list didn't have anything in there. (the fix had something to do with ipv6). I tried direct connecting my internet and the speedtest results were normal, so I've concluded that it has something to do with my router. However, I don't know how to do a firmware update or troubleshoot the issue on Ubuntu. I finally decided to give up on Ubuntu and switch back to Windows 7. However, my drive is currently formatted into ext4 and I need to go back to NTFS, how do I do that? Could I just use gparted?

I'm on Ubuntu 10.04 and I'm having problems with internet speeds on wifi. I have tried the two available networks on my university campus and both of them are very slow with 10.04. I'm not having problems with Windows 7 running on these networks. Although, the wired network works perfectly fine, with normal speeds. I've looked around for help but I could not find anything specific to this problem.
