SLOW INTERNET REALTEK8139(Genius LAN GF100TXRII)

GnaM · 01-02-2005, 08:36 AM

Hi,

PROBLEM
In windows I have, due to tremendous nice network, about 300 KB/s to 800 KB/s
download upload speed. After some struggle in configuring my network card under
SuSe 9.2, KDE 3.3 on my PII 233 MMX, 128 MB, AOPEN motherboard ........
(for reference, look at newbie section for thread :
INTERNET PROBLEM REALTEK8139(Genius LAN GF100TXRII) )
.......I finally gained access to Internet.
The Problem however, is that now I only have about 500 B/s to 2.0 KB/s .
It is really frustrating to wait 20 seconds for a website to be properly setup
due to it's complex contents or whatever.

What did I already try before bugging you ?
-First of all the newbie section regarding configuring my card.
-Google search doesn't provide many precedents to my situation.

My profile
SuSe 9.2, KDE 3.3 on my PII 233 MMX, 128 MB, AOPEN motherboard,
Genius LAN GF100TXRII
Internet connection is through LAN, the university here provides awesome download upload speeds.
I am a newbie regarding Linux.

Regards.

Hi,

You need more information ?
Of course, i guess that you will not be able to answer me immediately due
to the little information I have provided you with.
I think a good start would be if you would give me a list of all commands
I should execute, which in your opinion provides more relevant information,
and I will post them as soon as possible.

Regards.

this question has been asked and answered many times before, use the search function on this site in the future.

for the solution to this problem, read this. http://lwn.net/Articles/92727/

basically, some linux kernel's use a tweaked tcp window scaleing value.
this improves network performance, however some brobken routers and firewall's rfsuse to forward these packets.

anways... the bottom line... run these commands once as root

Code:

echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale
echo "net.ipv4.tcp_default_win_scale = 0" >>  /etc/sysctl.conf

XxSpaceBoyxX · 01-02-2005, 12:37 PM

the first command didnt work =(

[root@HAL9000 spaceboy]# echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale
bash: /proc/sys/net/ipv4/tcp_default_win_scale: No such file or directory

the second one didnt error but didnt give any confirmation of changes done

(i too have a similar problem, but i used search =-)

edit- checked the file and the default win scale was in there

qwijibow · 01-02-2005, 02:27 PM

those commands just write values to files, there will be no confirmation that changes were made.

the first command actually makes the change, the second command edits the boot script so that the change is made every time you boot. if you didnt manage to get the first command to work, then just do the second command, then re-boot.

Hi qwijibow,

Thank you very much for the information you have provided me with.

However, even though I did the commands and rebooted, I still am confronted
with the same problem.

I had the same results as XxSpaceBoyxX, the first command didn't work
because that file simply doesn't exist, and the second command did it's
work properly.

I have searched on this forum for similar cases as mine, but I guess
my problem is rather unique ???

Just a long shot, but I didn't install a firewall on my comp. this can't be it right ?

Regards.

qwijibow · 01-02-2005, 10:48 PM

its definatly not the firewall, but just to be sure.... as root run the command "iptables -vL" and post the output

GnaM · 01-02-2005, 10:58 PM

The requested output is as follows :
iptables -vL

PHP Code:



Chain INPUT (policy ACCEPT 0 packets, 0 bytes) 
 pkts bytes target     prot opt in     out     source               destination 
 
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) 
 pkts bytes target     prot opt in     out     source               destination 
 
Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes) 
 pkts bytes target     prot opt in     out     source               destination

I guess that isn't normal ?

Regards.

qwijibow · 01-03-2005, 09:38 AM

thats your firewall set to allow everything.

ok, if the above commands didnt help, im confused.

give as much info about your computer as you know.

how is it connected to the internet ? what distro ? what kernel ? what webpages work, what dont ? internet connection speed ?

GnaM · 01-03-2005, 10:32 AM

Hi qwijibow,

Internet connection
Here at the university we are connected to the Internet through LAN.
We have a very good download/upload rate here, about 300 KB/s --> 800 KB/s.
The connection from my comp. is traditionally with a wire.

Linux Distribution
SuSe 9.2 KDE 3.3.0

Kernel
Trying to find out....

How I had my Internet connection set up
First of all, I had deleted REALTEK from Yast.
Then I did the following :

PHP Code:



modprobe 8139too 
ifconfig eth0 134.128.124.31 netmask 255.255.255.0 
route add default gw 134.128.124.100 
 
and i used this to test it. 
ping 134.128.124.31 
ping www google com

Of course, after rebooting I lost those settings.
So afterwards I ran Yast again, put in EXACTLY the same information
as I did before, and now it not only works, but the comp has memorized
my settings.

ROUTE

PHP Code:



Kernel IP routing table 
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface 
134.184.124.0   *               255.255.255.0   U     0      0        0 eth0 
link-local      *               255.255.0.0     U     0      0        0 eth0 
loopback        *               255.0.0.0       U     0      0        0 lo 
default         rt-124.vub.ac.b 0.0.0.0         UG    0      0        0 eth0

Strange default rt-124.vub.ac.b instead of 134.184.124.100.
The latter I had to manually put in myself.
Also, vub.ac.b doesn't make much sense, because our university website is www.vub.ac.BE
IFCONFIG

PHP Code:



eth0      Link encap:Ethernet  HWaddr 00:C0:DF:01:B8:1B 
          inet addr:134.184.124.31  Bcast:134.184.124.255  Mask:255.255.255.0

          collisions:0 txqueuelen:0 
          RX bytes:2936 (2.8 Kb)  TX bytes:2936 (2.8 Kb)

213 errors ??????????

ETHTOOL

PHP Code:



Settings for eth0: 
        Supported ports: [ TP MII ] 
        Supported link modes:   10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
        Supports auto-negotiation: Yes 
        Advertised link modes:  10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
        Advertised auto-negotiation: Yes 
        Speed: 10Mb/s 
        Duplex: Half 
        Port: MII 
        PHYAD: 32 
        Transceiver: internal 
        Auto-negotiation: on 
        Supports Wake-on: pumbg 
        Wake-on: d 
        Current message level: 0x00000007 (7) 
        Link detected: yes

Why is my speed only 10 MB/s ??? shouldn't it be 100 or something ?

For the sake of clarification I will make a second post regarding some .conf files

GnaM · 01-03-2005, 10:48 AM

RESOLV.CONF

PHP Code:



nameserver 134.184.250.7 
nameserver 134.184.15.13 
search vub.ac.be ulb.ac.be

I have tried to add domain 134.184.124.31, changing order of nameservers,
changing websites to WWW.x.x.x.
Also when I type in 134.184.250.7 into my webrowser I can't get any connection.
But if I do it with the other 134.184.15.13 I get to some PHP page or something.
There you can click server or information. When I click server I get the message : Host 134.184.124.31 REFUSED.

sysctlp.conf

PHP Code:



# Disable response to broadcasts. 
# You don't want yourself becoming a Smurf amplifier. 
net.ipv4.icmp_echo_ignore_broadcasts = 1 
# enable route verification on all interfaces 
net.ipv4.conf.all.rp_filter = 1 
# enable ipV6 forwarding 
#net.ipv6.conf.all.forwarding = 1 
net.ipv4.tcp_default_win_scale = 0     
---> This last one is caused by the commandline I executed before.  
--->echo "net.ipv4.tcp_default_win_scale = 0" >>  /etc/sysctl.conf

Now the following is huge. To make it easier for you, these are the ONLY changes I have tried :

PHP Code:



#***********SOME POSTS ADVISED TO CHANGE THIS BUT IT DIDN'T WORK OUT******************** 
alias net-pf-10           ipv6 
#install net-pf-10         /bin/true           #By uncommenting THIS line 
#**************************************************************************************************** 
 
#***********SOME POSTS ADVISED TO PUT IN THIS BUT IT DIDN'T WORK OUT******************** 
alias net-pf-10 off 
alias ipv6 off 
#**************************************************************************************************

Here it comes, but I guess the above info is more than enough....

Lol,
I just see it now, I shouldn't have touched that BIG file at all, I had to
put in those changes at local instead......

Anyways, that file is just plain empty....

you can get the kernel version with the command "uname -r"

all those settings look good, what download speeds do you get ?
and what download speeds do other computers on the network get ?

GnaM · 01-03-2005, 02:21 PM

the command uname -r gives me : 2.6.8-24-default.

Whenever I open a website, it takes a while to load, i get about 650 B/s .
In Windows I get at least 50 KB/s. And this is for every computer on the LAN....

I guess my problem is not easy to solve.
All of the documentation I came up with, nobody had any remarks on them,
so I guess they must be OK. I really have no idea what to do next,
are there any more commands I can try then I already did ?
Someone any suggestions of as to what might be wrong ?

Is my problem unsolvable through the forums, and
Should I try other linux version ?
Should I change network card ?

But can you guarantee my problem will be solved ?

Regards.
