slow net in ubuntu

Dear friends, I use ubuntu; but my internet is very slow here
(compared to in windows) and the download speed(30kbps) is quite less
than in windows(200-300kbps); I use the same dns in linux as in
windows; and I have already disabled IPv6 from firefox (about:config --
> network.dns.disabl.....). But I have still been suffering from this
problem.
Kindly help me.
Thanks.

Well, show us your network settings

-------- standard debug network problem text/script follows: ------------
dump_net.txt version 2.2



Once you get your network running you may want to run xx one last time
and save the output file for disk crash/new installs

Might not hurt to save xx for one of a network debugging checklist step.


The following script dumps your hardware status, network settings and
config files used in network setup. We need them to troubleshoot your
problem.

If you are having to use windows to access Usenet:
Format a diskette on the windows system.


Copy the following xx.txt script into xx.txt using notepad.exe
then save xx.txt to the diskette.

Feel free to include the #**** start/end xx.txt script **** lines.

If using linux for usenet access, su - root, copy script text into xx
chmod +x xx
./xx

and include a.txt (if on linux) or dosa.txt (if on windows) in your reply.


NOTE: to become root, you need to do a
su - root
not su root

and then copy xx.txt to the diskette.

On some linux distributions, you may need to get into the User/Group
screen, show all users, double click root, create the password, and
enable root. Root's password should never be the same as anyone elses.

To move xx.txt from diskette to the linux box, click up a linux terminal
su - root
(root's passwd)

mkdir -p /floppy
mount -t auto /dev/fd0 /floppy
tr -d '\015' < /floppy/xx.txt > xx
chmod +x xx
../xx

Back on the windows OS, you can cut/paste the a:\dosa.txt into your reply
under windows.
Do not attach it.

If you are dual booting the box, you can copy xx.txt to linux from windows.
Note: The following assumes /dev/hda1 is where windows is installed on the
first partition on the C: drive

mkdir -p /doze
mount -t auto /dev/hda1 /doze
tr -d '\015' < "/doze/whever/you saved/xx.txt" > xx
umount /doze

On windows you can read dosa.txt from a linux partition if you installed
windows linux driver from
