knoppix may ping everything but can't load a page

**jacksonon** · 03-22-2005, 03:30 PM

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.

Hello,

I've downloaded the newest knoopix 3.8 Now I may change duplex settings and speed setting using ethtool, but my conection stil doesn't want to work well. I get about 25% lost packets using ping in local area and in the internet. Does someone know what cause may be ?

Below i present some info given me by ethtool

Code:

        Supported link modes:   10baseT/Half 10baseT/Full
