Internet connection problems

Hello,

Newbie tries to install SuSE 9.1 on a PII-266/256 behind a Vigor 2200 E router, dual boot with w2k. Network card: Linksys NC100 Network Everywhere Fast Ethernet 10/100

Could be hardware limitations, but compared to w2k suse 9.1 seems terribly slow.

I managed to get an internet connection (ADSL 2048/416 kbps) but upload traffic seems very very slow or blocked completely.
I ran speedtests (http: // www . speedtest . nl)
Under w2k I got around 1900/340 kbps download/upload
Under SuSE dowload speed was over 2700 kbps. Upload failed. Got a message that a script (javascript) froze khtml or something similar.

Added a line in modprobe.conf: install ipv6 /bin/true. No effect.
Turned off the suse firewall (was it on before?). No effect.
Set dhcp instead if static ip address. No effect.

After running speedtest a second time and rebooting, i can't connect to internet anymore.

What should i do?

Hi,

stopping then ipv6 was the first step ;-)

Now put the DNS-Servers from your provider as DNS-servers in your network configuration:

for example: 194.25.2.130 194.25.2.129 (DNS Servers from 1&1)


linux:~ # yast dns

Nameserver1 194.25.2.130
and
Nameserver2 194.25.2.129

I got Suse 9.1 Prof. running on my desktop-pc and I wasn´t able to connect to the internet (I got DSL with a Draytec Vigor 3500).
After giving the DNS-Server-Adresses, I was able to connect to the internet with ...hmmm...ISDN-Speed
After the ipv6-trick, I´m faster on DSL with Linux, than my Win2000-PC.

So try out the DNS entry ...

Make sure this statement is in your etc/modprobe.conf file.

alias net-pf-10 ipv6
install net-pf-10 /bin/true

While I'm running a 3rd clean install:

stopping then ipv6 was the first step ;-)

And how do I do that?

in: /etc/modprobe.conf
adding: install ipv6 /bin/true.
after: alias net-pf-10 ipv6

or

in: /etc/modprobe.conf
change: alias net-pf-10 ipv6
into: alias net-pf-10 off ipv6

or

?

linux:~ # yast dns

What's this?

I can leave search domain entries empty?

Thanks.

You should have (2) lines in modprobe.conf for net-pf-10
Make them look like this;

alias net-pf-10 ipv6
install net-pf-10 /bin/true

alias net-pf-10 ipv6 install net-pf-10 /bin/true

is the 3rd alternative given.

What should it be?

Post your modprobe.conf

I tried to post modprobe.conf on the oher machine, but apparently I'm logged out everytime.
Is it because I reject cookies from this site? If so, how can I reverse that?

I've entered my isp's name servers (instead of my router's ip). I can connect to the internet. Download speed is ok. Upload speed is around 30 kbps and should be 360 kbps.

I've added Harry's line in modprobe.conf but can't notice any difference.

Did you reboot?

Yes

Hello,
i cut a part out of my /etc/modprobe.conf
That´s all you have to do in Suse 9.1!

it´s at line 314 downwards:
------------snipp----------------------
alias net-pf-1 unix
alias net-pf-3 ax25
# install net-pf-3 /bin/true
alias net-pf-4 ipx
# install net-pf-4 /bin/true
alias net-pf-5 appletalk
# install net-pf-5 /bin/true
alias net-pf-6 netrom
# install net-pf-6 /bin/true
alias net-pf-10 ipv6
# added by bikerpete -> only next row !!!
install ipv6 /bin/true
# install net-pf-10 /bin/true
alias net-pf-11 rose
# install net-pf-11 /bin/true
alias net-pf-15 af_key
alias net-pf-17 af_packet
alias net-pf-31 bluez
------------snapp-------------------------

What I meant with "yast dns" is a command, you could execute in a shellbox as root (su).
You can use the graphical interface for YAST, too - but I like the faster commandline way
Hmmm ... take, the YAST, go to network and insert one or two DNS Servers!
If you own a DHCP-Server, you should get the DNS Server infpormation from the server.
Otherwise, you should try to type in a DNS-Server-IP-Adress of your provider.

Still:

Download speed: OK;
Upload speed: more than 10 times too slow.

Any Clues?

I ran dslreports tweak test:

1. Your Tweakable Settings:

Receive Window (RWIN):63940
Window Scaling:0
Path MTU Discovery: ON
RFC1323 Window Scaling: ON
RFC1323 Time Stamping: ON
Selective Acks: ON
MSS requested: 1402
TTL: unknown
TTL remaining: 55

Notes and recommendations:
Change MTU to 1500 (FAQ #652, #695)
Choose RWIN between 19628 and 51874 (FAQ #586)
See tweaks/Unix page
Read the tweak FAQ

2. Test 146000 byte download

Actual data bytes sent: 146000
Actual data packets: 106
Max packet sent (MTU): 1430
Max packet recd (MTU): 1430
Retransmitted data packets: 0
sacks you sent: 1
pushed data pkts: 8
data transmit time: 0.710 secs
our max idletime: 135.9 ms
transfer rate: 105035 bytes/sec
transfer rate: 840 kbits/sec
This is not a speed test!
transfer efficiency: 100%

Notes and recommendations:
Upload packet less than your MTU (FAQ #1492)<=======
Good data stream (no/few rexmits)

My problem could be in the "Upload packet less than your MTU" note. What can I do about it?

You can set the MTU for your network-card in YAST.

NIC settings, change, special entries (or something else - I got the german version runnin´ , so I can´t tell you the exact path).

I got:

Downstream:
110.4 kByte/s
883.2 kbit/s

and
Upstream:
14.57 kByte/s
116.56 kbit/s
