Problems with my internet connection

[archangelmorph]

I'm trying to get my PC at home to connect to the internet and i'm having no luck whatsoever..

When I try to connect to the router using DHCP the Pc isn't allowing the router to assign it a dynamic IP address..

It's assigning itself a strange IP address starting with 169.something or other..

I've tried setting a manual IP address and it doesn't work..

It says its physically connected but I can't connect to the internet..

When I try to repair the connection it says it failed when trying to renew the IP address..

When I try to ping www.bbc.co.uk or www.microsoft.com it says it can't find the site..

When I try to ping the router it just loses all the packets..

When I check the status of the connection it looks like it's just sending packets and never recieves any..

I've got two ethernet ports on the back of my PC and it does exactly the same with both of them..

I bought a PCI gigabit ethernet card and it does the same with that too..

I've tried to connect to the internet in 3 seperate houses using three seperate connections from three seperate ISPs and it does the same thing..

I'm getting a little depressed cuz I don't know what to do at this stage, I'm not very good with networking..

I really hope someone can help me..

well, you do plugin the network cable into a netcard? , sorry for that, I coudn't resist

1. What kind of MB do you have? 2 network adapters is not very common... try disabling from BIOS both of these when the external one is plugged in.
Then check that card is working (control panel - system - device manager" ) according to WinOS
2. Is the router configred to act as DHCP server? maybe better try connecting directly to Internet.
3. What kind of Internet do you have? One that gives you Ip address(dhcp) or one that requires to write a "hard" IP ?

The fact that net adapter gets IP like 169.x.x.x, means it cannot find any DHCP server.

1. Motherboard is Asus A8N Duluxe SLI.. I'll try disabling the the network adaptors from the BIOs and connecting through the PCI card tonight and let u kno how it goes..
2. Yes the router is configured, we have three other people using it at the moment and they can connect fine..
3. Internet is DHCP as it's assigning IP addresses from the router to my flatmates PCs, just not mine ..

The last time I went through diags with NTL they suggested it maybe something to do with my TCP/IP stack!?

I don't know what that is or how to fix it.. any advice would be much appreciated..
