Networking :: Get Speeds Closer To 1000Mb/s?
Apr 4, 2010
First of all I have two Gentoo Linux computers. These computer both have Ethernet ports that support 1000MB/s speeds. Here is the ethtool report for both of the cards.
[code]...
Link detected: yes I have a Cat6 cable connecting the two computers together for direct file backup. Now when I run iperf to check my speeds, I get the following:
[code]...
My question is why is this so slow and how do I get my speeds closer to 1000Mb/s?

It was recommended that I post the results of a service scan performed against a remote machine. However, before I get flamed for lack of proper etiquette, I asked for advice prior to posting. So, here goes. I have a been getting scanned repeatedly by the same group of addresses for well over 2 months. I decided to take a closer look once the scans stepped up a notch. By "stepped up a notch" I mean more specific. All the originating HOST are using either port 12200 or port 6000. All with one exception, appear to be located in China. The scans are blatant. Over and over again. I noticed some timing between scans that seemed to match up with a European location as well.
The first question would be if I could get in trouble for the remote host actions. I mean, I have noticed pings directed past the router to the internal network now in my linux logs. Could the attacker/scanner be using me as a bounce for other stuff? The scans, as stated before, never stop.
I ran a scan against one of the host out of curiosity. You can check it out at http://pastebin.com/5qcKSgC0. It appeared to be a school in china. Should I report it? IF so, how would aI report it to some guy in china, I don't speak or write Chinese.

Code:
tupe=("File",("Open","Open a file"),"Edit",("Cut","Cut a file"),("Paste","Paste a file"),"About",("About","About the program"))
menutitle=""
menupos=0
for items in tupe:
if type(items)==str:
[Code]...
I'm trying to understand how to make "File" be the parent information for "Open","Open a file" and "Edit" to be the parent of "Cut, Cut a file" and "Paste", "paste a file". Does anyone have a suggestion for accessing the a nested tuple in this manner? The above code does not quite do what I want it to. The above code is for visual purposes, but I'm learning how to refactor for wx.python.

I am new to Linux and have recently dropped Windows 7 (and windows all together for that matter) for Ubuntu 10.04.I love the look and feel of Linux and enjoy using it more over Windows. Despite this I am experiencing a serious problem which may cause me to revert back to Windows 7.I have a USB 3G modem: ZTE MF622 on the KKTCELL network.I have got this modem to work with wvdial and Gnome PPP, however i cannot get speeds over 60kb, Windows gives me well over 200kb.
I have tried a number of things but nothing has worked, it seems that no-one has posted a solution to this annoying conundrum.

I have had a fairly perplexing problem with my Lubuntu Maverick installation on my laptop for the past few weeks. My laptop is connected to a DSL-based LAN via 100mbps Ethernet - pretty typical. Usually, the download speed from most websites tends to be around 340-350kb/s. However, its Ethernet connection seems to be having some strange hiccups. The speed starts out at normal ranges, but after about 5-10 minutes of internet use through any means (be it loading normal web pages, streaming video, downloading a file via a browser, or even other uses such as downloading a torrent using Transmission, or even a command line application such as apt, aptitude or wget, etc), the speed suddenly drops to around 40kb/s and will not raise again.
Once this happens, the drop is seen across the board. Again, once it happens, the speed of everything that accesses the internet is affected. Web pages load slowly, all downloads will only operate at a maximum of 40kb/s, whether it is from any browser, or wget in a terminal. The speed stayed slow until I restarted, which would give me another 5-10 minutes. My troubleshooting attempts yielded some very strange results, which I will relate here:.......

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 have a BCM4321 and have not been able to get it to connect at N speeds, but finally got it working with broadcoms drivers from their site. The drivers in jockey would only get me b/g speed not n. Quote:Originally Posted by lshw -c network
[code]...
here is a small script that I wrote to assist others in getting it installed and working. First download the drivers from [URL]... then copy this into a script: compile.sh
[code]...
if the kernel changes then you will have to do this again. if you don't want that hassel and don't mind staying on your current kernel then lock it in the package manager.

I'm using a Netgear WN11v2 wireless USB card, which I've read some people can't even get working with the default Ubuntu wireless driver. It works for me, but it disconnects fairly often, and download speeds are extremely slow, like 12-15 kB/s. I have broadband, and am running Ubuntu 11.04.

My kernal version is 2.6.32.10-90.fc12.i686.PAE
I'm running Fedora 12.
It auto-detected the card, but it's only operating at 100mb/s. It's connected to a gigabit switch. The driver auto-installed for the card is r8169. How do i get it up to the speed is should be at? Its kinda why i bought it...

I am running Ubuntu 9.10 on a Dell inspiron 1520 with intel 3945abg wireless card. I am fairly new to linux and just installed it earlier in the day. Everything so far has been easy to setup and get running as well as the networking or so i though...
I can connect to my network and browse we pages just fine. However, when I download a file the speed starts high, drops down to around 50kbps and then works its way back up to around 1.3 mbps before dropping right back down. I tested a file on megaupload and it seems to bounce between 50kbps and 1.5mbps nonstop.
The driver i believe is the iwl3945 if that is the default driver. I have tried disabling ipv6 and that didnt seem to change anything. I've looked around on google and the forums and havent been able to find anything on how to fix this.

I am currently staying on a university campus in Taiwan. Internet on Ubuntu Lucid 64bit here is often painfully slow, except for connections to Taiwanese websites. I dual boot with Windows 7, and there is no problem there. For instance, I downloaded the same piece of software (Spideroak) on both Win and Ubuntu, with Ubuntu I had to try repeatedly as the download would not complete, and in the end it took several hours to download. On W7, it took 10 minutes. What is Windows and Ubuntu doing differently?
I tried disabling ipv6 for this session by running sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1, as a number of posts mention improving connection speed that way, but no effect.
I know that websites from Taiwan are working well, because I am getting my Ubuntu updates from a Taiwanese mirror: updates are fast, except for packages in the 'partner' repos (presumably not loaded from the mirror) which take hours to load, if at all. I don't want to depend on Windows for large downloads... (I don't want to depend on Windows for anything).

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.

I've just managed to access my windows share from Ubuntu but am now getting write speeds (to xp share) of only 9MB/s over my wired network, anyone have any ideas as to why this may be? I've googled but can find no specific answer.
My NIC is:
Ethernet controller: Broadcom Corporation NetLink BCM5784M Gigabit Ethernet PCIe (rev 10)
(from lspci) on a Dell studio 1737)

I'm wondering if there is anything I can do to get the best speeds possible. I pay for 16mb/s connection (with charter) and I was getting about 4mb/s. After upgrading firmware, and changing some encryption settings on my router, that went up to about 6mb/s. It's improvement, and I'm happy with that, but I'm looking for that 10 more mb/s
So, is there anything in Ubuntu to tweak to optimize connection speeds? Also, if it affects anything, I'm using a linksys WRT320N router. I was going to use the 5.0ghz band, but my wireless adapter is an 802.11gb, so I'm stuck with 2.4.

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 used www.speedtest.net to test my download through firefox first on vista and then on Ubuntu (9.04) - it is a dual boot machine.
Whilst I get between 18 and 19 mbs on Vista I only get 4.5 on Ubuntu - how do I fix this - is it an issue with my ethernet drivers or my setup?
I am on a 20mbs cable modem - I connect via an ethernet cable to a router - which obviously connects to the cable modem.

I've been using Ubuntu for a while (though I would not consider myself an "expert") and have just gone back to school. I live on campus and connect to the network through an ethernet cord. On Windows, the download speed is 1 Mb/s by default, but if you go through and configure the network card (turning off the auto-negotiation and setting the speed to 10, duplex full) the download speed will increase to 10 Mb/s, a considerable difference. So, I tried to do this in Ubuntu by opening the terminal and typing the following:
sudo ethtool -s eth0 autoneg off speed 10 duplex full and all of a sudden, my computer isn't connecting to the internet. When I type: sudo ethtool -s eth0 autoneg on it suddenly starts working again.

I've recently purchased a TP-WNL951N PCI Card for wireless N stuff. I have a Netgear WNDR3700 for use with my AP and I've confirmed that within windows XP I can connect at 300mb/s.
Within Ubuntu though, it only goes up to 54mb/s. Is there something special I need to do to enable wireless N speeds?
Here's some info that I should probably put in:
Code:
root@Linux:~# lspci -nn | grep Atheros
05:00.0 Network controller [0280]: Atheros Communications Inc. AR5008 Wireless Network Adapter [168c:0023] (rev 01)
root@Linux:~# ifconfig wlan0

I have installed libapache2-mod-bw and it works great to throttle download speeds to the clients (i.e. - the bandwidth out of the server can be controlled just peachy).However, I need to limit the bandwidth *into* the server from specific networks because my WAN links are tiny and do not have QoS or shaping of any sort (I know, I know - contracts in place - will be fixed in November - not my design).I know that there are ways to throttle this at the interface level (e.g. - wondershaper) but I'd like to allow full bandwidth to the clients that are connected locally. The server in question is for web file transfers (under apache2 on 443) and expected file sizes are up to 2GB so a per-network limit would prove helpful.

Last week I attempted to get "up to speed" with my Comcast cable connection... Ubuntu 9.10, Dell Vostro 400 desktop, Firefox 3.6.13... Comcast says I should have 12 Mbps connection... if I get 1.0 Mbps, I'm doing good... they just tested everything, and said everything is fine on their end. They use [URL] and connects to a server in Chicago, 60 miles away. That gets fantastic speeds, and it's a durn shame the internet doesn't store all its files there!! I use [URL] for my tests, and it uses a server in Dallas TX.
I go to my girlfriends house, and her AT&T DSL line has d/l speeds of 4.5 Mbps or better!!! She's running XP Pro on a Dell machine. So, started digging on the web and thru the forums, and found this:
[URL]
But, like ALL too many things, it's dated... it's from 2008... I've set my settings to what is there, and disabled ipv6 in Firefox. Hey, now, I'm sometimes up to 1.4 Mbps!! Also found this, but no date...
[URL]
Reading forums, I see that folks have said there is a network connection problem with 9.10... and then I see that others are saying the same thing about 10.04 and 10.10!! I have 10.10 on my laptop and had to fight to get its Atheos card to be recognized. Running some tests [URL] gives me weird results: Download 2.64 Mbps, Upload 4.12 Mbps. NOT what it should be. Similar results from testmy.net.
Dunno exactly what info is needed... Speedguide.net gives me results below, but I've tried changing numbers (says my RWIN is low) and nothing changes:
--------------------------------
TCP options string = 020405b40402080adf1dca100000000001030306
MTU = 1500
MTU is fully optimized for broadband.
[code]....
So, today, find, once again, that I'm d'ling in the range of 90/KB/s (719 Kbps)... disgustingly slow. I go on my HP laptop and run the test, and it says 1.6 Mbps. So, desktop directly connected to router is not even 1 Mbps, and wireless connection is faster? Neither of which is close to what I should be getting...

I'm having a variety of problems getting a new PC working properly, getting a reliable wifi connection is one of them. Earlier today I upgraded to 10.10 using my wife's account and download speeds were frequently at a reasonable 800kbps at times. This evening my son complains about the slow speed and a test shows 133kbps download with 616kbps upload. My own PC connected by wire to the router works OK.
A couple of days ago this problem seemed resolved when I installed Wicd but didn't configure it. I thought Network-Manager would have been removed but was still present. However, a downloads test showed 6Mbps. After today's upgrade slow downloads have returned.
I'm currently using this PC with a wifi link to the router and am connected to the Forum. If I hover the mouse pointer over the N-M toolbar symbol a window opens saying-
Wireless network connection 'Auto MYESSID'active:MYESSID(67%) If I right mouse click on the N-M symbol and select Edit connection... the wireless window reports that I was last connected 3 days ago. My own PC's wired connection window says against Auto eth0 that I've never used this. Both these are untrue. I wondered if having a hidden ESSID doesn't help? I'm left thinking that the rt2500 based wifi card needs replacing. We're some distance from other houses.

I have enabled the xhci_hcd module, but my usb 3.0 hard disk is still only being recognised at "480MB/s" connection speeds (with benchmarks confirming it is definitely running at usb 2.0 speeds.
The usb 3 controller is the NEC chip everyone seems to be using. The devices is a Seagate free-agent go (something like that anyway) with the usb 3 adapter.
lsusb takes a good couple of minutes to run, and doesn't mention the NEC controller at all, lspci does list it, and devices plugged into it work, but only at usb 2 speeds as mentioned.
I have a relatively high competency with linux (mostly with fedora over the years) so don't worry about solutions or requests that are quite technical.
Happy to provide machine specs if more detail is required, running Fedora 14 x64 with everything up to date. Specs: [URL]

I can't get Gkrellm to show my fan speeds anymore since reinstalling Ubuntu.I have tried 9.10 and 10.04 and tried installing packages to maybe get the drop down to show up for fan speed but still nothing.I have installed Xsensors and that shows fan speeds correctly but I want to show them in Gkrellm like I used to have. Now every other temp gauge is working like it used to but the fan speed monitor.
