Can't connect, please help me! [URGENT]

Hello!

I can't connect on 1 of my computers.
I have a Ice.Net D-35 router.

On one of the computers I am able to connect to the internet
but not the other one.

I think the TCP/IP settings is the problem.
I scanned the computer that can't connect with antivirus & malware programs.
Found many kind of viruses and took them all to quarantine.

I used microsoft's Fix it TM, to fix TCP/IP and attempted to restore the host file in windows32.
So I belive the host file is good, but the TCP/IP did not change.

I also tryed to set "assaign an IP adress automaticly" and tryed to put a custom one.
Nothing worked.

When I write ping localhost in cmd, it succesfully pings it.
And the results are that I get 4 and send 4 = 100%

But when I attempted to ping the IP I had one time it said:

can't connect to the DHCP server or something like that...

SUMMERY:

Can connect with the router on 1 computer but not the other 1.
My router: Ice.Net D-35
It's succesfully ping the local host.

NOTE:
My spelling is not perfect because I'm from sweden.

Please help me, I don't want to re-install the computer or send it to microsoft...
That would cost to much...

Please!

 

Login into the router and enable the DHCP server. If the router has any turbo or speedbooster TURN IT OFF! if after fixing or allowing the above you still cant connect disable the encryption and try and connect. If you connect this way, then try the WPA encryption again.

 

karlhaywood: I think the DCHP is enabled cause I can connect with the router on another PC.

1. Both wired
2. The device manager: PCI MODEM Drivers not installed...
How do I install PCI MODEM drivers if there is no connection?

3.. you said IF the device manager does not show anything...

 

Open Command Prompt and type ipconfig/all and copy and paste the results on here.
