Ubuntu 11.10 SLOW DSLreports speeds
I'm on a wired connection, and on a (supposed) 30x5 connection from Time Warner Cable, however in ubuntu the flash speed test on DSLReports.com gives me a download speed of ~1 meg, upload seems to be on at about 204 megs. My first thought was that it was an issue with the linux flash player, but since the upload speed seems accurate, that doesnt seem like the case.
Now, i'm used to the "plug and play" style of networking in Window$, but im wondering if theres something i missed? I did a goggle search for dslreports and linux, but all i found was a discussion about the speeds between one person and a server in IL, and a particular provider (not TWC at that), so i'm wondering if theres something i might have messed in setting up my networking. |
There are several things to consider when measuring bandwidth. Some are:
1 - Your clock. If I understand, you're saying you get 30Mbps down and 5Mbps up. If you're getting 204MB/sec, that rivals optical fibre. I highly doubt that number is accurate at all. 2 - Your share of the load. Cable or FIOS will share with the rest of the people on your distribution center. 3 - Distance/load of the testing site. DSL reports might not be the best test. How far is it? How loaded is the site? http://speedtest.net/ tries to find the closes geographic area around you. Try that. 4 - Browser/drivers. What browser are you using? There is a chance your drivers could be not the best on that version of Ubuntu and give bad results but that'd be rare. |
1) you're right, it's supposed to be a 30 meg down, 5 meg up speed. sorry on the 204 i quoted, it's a typo (i'll correct in a moment) but i meant to say it was 2-4 not 204.
2) yep, i'm aware of that, and sorry i didnt say it, but i was also booting into windows to see what i was getting on it, and they were significantly improved, by about 10X (so if i saw 1 meg up inlinux, i'd see about 10 megs from windows) 3) distance: i was trying pretty much all of the servers, but i'm in nc, and I was trying DC, ny, nj, il... basically ally of them at different times. 4) in all cases I use Firefox. edit to add: going to run some back to back windows then linux tests, and see where exactly i stand, windows version is first line, linux will be second: to nj: http://www.dslreports.com/im/99688518/1566.png http://www.dslreports.com/im/99688607/9898.png to Il: http://www.dslreports.com/im/99688533/2422.png http://www.dslreports.com/im/99688625/4156.png to DC: http://www.dslreports.com/im/99688540/6160.png http://www.dslreports.com/im/99688594/4988.png |
bump for any ideas

Verify your NIC is running at 100Mbps or higher. Also check to see if your wireless is turned off.
What NIC chipset are you using? Can you update to your latest drivers? What happens when you test at http://speedtest.net/ ? |
Sorry tolling, apparently this thread had slipped past my radar as i was watching new posts.
According to connection info, i am connecting @ 100 MB/s, speedtest.net is showing similar results as above from dslreports.com. It's a gigabyte 970a-d3 motherboard with built in RealTek LAN, although oddly i'm struggling to find the exact chipset edit: found it, it's a RealTek RTL8111E edit 2: downloaded linux driver, followed these instructions (with some modifications cuz im still a windows convert :P ) Modification was to simply to select "run script as program" through gui, instead of pathing to it in terminal.

Code:
lsmod | grep r8168 Code:
ifconfig -a Code:
eth0 Link encap:Ethernet HWaddr 50:e5:49:53:60:d9 |
What happens when you test at http://speedtest.net ?
|
As i said, similar speeds as DSL reports
|
Looks like this was reported as a bug on the Ubuntu bug forums. Can you try upgrading to r8169?
Hard way: http://wookie.co.nz/wordpress/rebuil...le-for-ubuntu/ Easy way: Look to see if the package exists in Ubuntu's package manager. |
Well, as far as i know I have ubuntu up to date via update manager, should it not be installed by that method if its there?
|
Updating just means you have your distro's latest packages not necessary the latest packages from the developers.
Hm.. if you see nothing from "sudo lsmod | grep r8168" do you see anything from " sudo lsmod | grep r8169"? If you're not seeing output from r8168/9 then means it's either not installed, not loaded or not you don't have permission to see it. r8169 has a bug with dropped network packets so you really have to try both to see which one works best for you. When you did a "lsmod | grep r8168" did you do it with a sudo? If you have slocate/mlocate installed try "locate r8168" and "locate r8169". If you don't just do a "sudo find / -name r8168 -print" and "sudo find / -name r8169 -print". If we can find what you have installed, at least we can load and unload modules without the need of a reboot to test things out. If needed we might need to blacklist something as well. Please forgive me speeeling and garmmar mistakes. Over work and under booze makes me go something something. |
Code:
david@david-linux:~$ sudo lsmod |grep r8169 |
8168 was the one i had downloaded yesterday, running the script from GUI didnt seem to do it correctly, although it appeared to. I followed the instructions through the terminal, and it seems to have fixed the issue!
