knoppix may ping everything but can't load a page

Hello,

I'm newbie to Linux and Knoppix. I've run it from Live CD to install it
and get some more experience with this system. But before installation I
want internet connection for all help I can get. And that's where the
problem starts.

My computer has ASUS K8N motherboard with Nvidia nForce3 250 chipset.
It's placed in the network and connects with internet by hub->router. I
run network-setup (as normal user and as a root), everything went ok.
After that I'm enable to ping other computers in network and in
internet, but connection is very slow - so slow, that it was a success
when I saw a title of one web page. Also when I try to connect to router
via http I get user/password popup from it, but after that it tries to
download a page from it so slow as from www. Propably it can be a
problem with full duplex on the ethernet card (as it was on win xp) -
net works well only when duplex is set to half. But I couldn't change it
using either mii-tool and ethtool. Mii-tool says there are no active mii
interfaces, ethtool can't get full information from eth0 (only some
basic) (I tried also as root) . And I wasn't able to find information
about option in which my card is working - is it half or full duplex.
With ethtool I wasn't able to findout is my card working as 10Mb or
100Mb. When I run Knoppix from CD on other computers in the net, it
behaves very well - I get normal connection to www. Below i present some
of my actions. I hope someone will help to solve my problem.
Regards
kuba


NETCARDCONFIG

ifconfig eth0 192.168.0.11 netmask 255.255.255.0 broadcast 192.168.0.63 up
route add default gw 192.168.0.1
SIOCADDRT: File exists
auto lo eth0
Setting Nameserver in /etc/resolv.conf to 193.110.120.5
Done.

MII-TOOL

ETHTOOL

root@ttyp2[knoppix]# ethtool eth0
Settings for eth0:
Supports Wake-on: g
Wake-on: d
Link detected: yes


ETHTOOL 2

root@ttyp2[knoppix]# ethtool -s eth0 \speed 10
Cannot get current device settings: Operation not supported
not setting speed
root@ttyp2[knoppix]# ethtool -s eth0 \duplex half
Cannot get current device settings: Operation not supported
not setting duplex

I think I know where the cause is. Drivers for my net card (forcedeth)
seem not to support most of ethtool and all of mi-tool commands for my
card. My computer is brand new. I'll try with newest version of Knoppix
(3.8), as I saw some patches to the Kernel connected with this subject.

new knoppix helped somehow. i know that duplex issue isn't a reason of
my problem. i may change it now, but internet still doesn't works (well)
.. i have a lot of packets lost bout 25 percent in local area and in
internet. does someone know how to solve this problem ? below I present
some of my settings given me by ethtool (mii-diag still doesn't work)

Settings for eth0:
Supported ports: [ MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
