Wired connection painfully slow in F15

[Azriel]

Hey, some of you may have seen my thread in another forum that ive recently moved from Ubuntu 11.04 to Fedora 15
So far im really happy with my decision but i have had a similar issue crop up that i had in Ubuntu where my wired connection is painfull slow.

I just ran a speedtest

and in my win7 partition i can get 700kbps to 1.2mbps in download speeds

however i just downloaded an 80mb file and was getting speeds that never peaked above 200kbps, as well browsing can become brutally slow to the point where some pages actually do not load.

I'm not sure if anyone else has ran into this problem, im running the ethernet port that came with my Asus m5a 78AL motherboard could this be a Mobo driver issue?

if theres anyone other information you need please let me know

Some ideas,

Run ethtool (yum install ethtool if it's missing) on the interface and make sure it's full duplex, it should not be half-duplex and the Speed and Supported/Advertised link modes should look good (having a super slow mode like 10baseT as the only link would be bad if your port is really a 1Gbit)

Even better, just run ethtool on the interface and post the results in this thread

Try removing/disabling the IPv6 interface, Fedora makes one by default, maybe Ubuntu doesn't but sometimes
the ipv6 interferes with things.

You can run system-config-network as root (yum install system-config-network if it's missing), select the Devices tab, select the interface, hit the Edit button and uncheck "Enable IPv6 configuration for this interface" -> OK, File->Save, File->Quit

The forum has a lot of posts about disabling ipv6

hi sorry ive taken a wee while to get back to you not had the chance to sit at my pc in a couple of days,
i installed ethtool using the command line and when i tried to run: ethtool: badd command line argument(s)
for more information run ethtool -h
when i tried to run it in root i got: cannot execute binary file.

i then uninstalled ethtool and reinstalled it using the package manager only to get the same issue.

also as default fedora had enable ipv6 unchecked

Yeah, you have to tell it which interface to look at (did you try "ethtool -h" for help like it asked?"

ethtool p23p1 (this is an i/f on the pci bus p -> pci and the numbers are various id numbers)
ethtool em1 (this is one right on the motherboard 'em' --> embedded)

or whatever yours is

you can find what all your interface names are with:

ip link

I'm butting in here because of this description of the GUI system-config-network window ("Devices tab") and this thread's heading specifying "Fedora 15." This description fits all previous versions of Fedora I can remember, but not Fedora 15. If there is a way to get the "old" "Network" window in F15, I'd very much like to know how to do it!

I'll point to my post #2:

(yum install system-config-network if it's missing)

for some weird reason they only installed the system-config-network-tui version in Fedora 15, you probably need to install
system-config-network

Then you'll have the Gui app I described

My, my. It was like meeting an old friend! Thanks so much.

But isn't it comforting to know that others know better what we need, like, and use better than we do ourselves?

ahh right thats DEVNAME (palmface) ive got it now :P it also took me a minute to work out the that P4PL in terminal was actually P4P1 (double palmface)

this is the ethtool printout

Azriel:

that looks completely as expected. the Speed being less than 1000 is likely due to a switch/router somewhere on your network being 100Mbit. This is backed up by the link partner advertised only going to 100
Duplex of 'full' is what you want and the failure to get wake-on-lan and link status is expected since you did that command as a non-root account.
There was a known speed bug in Fedora 15 but that was only for the wireless atheros chipset and shouldn't affect a wired port. So I don't know what your problem is here.

ach el dissapoint i was hoping something was going to be wrong there and i could sort it out...

the only thing i can think of now is "is the kernel supporting the mobo"

because its the onboard ethernet the kernel just might not like the mobo i have, chances of it being that though are so slim i feel ridiculous even mentioning it.

when i get back to my computer i'm going to check my cables again even though its working fine in windows.
