Repair network connection does not fix the problem , I have to assign

[zillah2004]

I have got Satellite Toshiba Laptop A-100 that is running Windows XP Profe SP3.

The computer is connected to a D-Link router (DHCP server) that is connected to a cable modem.

Out of sudden the laptopl stopped working on the internet although the network connection is repaired more than one times.

And the same problem with wireless card.

If I assigned static ip addresses to both wired and wireless card they work,,,both of them not only one

Wired card is : Intel® PRO/100 VE Network Connection.

Wireless card is :Intel® PRO/Wireless 3945ABG Network Connection

I tried to test my laptp on another router (Netgear) which is connected to another ISP same problem is going on with both wired and wireless cards.

What can cause this problem ?

Obviously it is not the ISP (I tried two different ISP), nor cables (because I tried more than one), nor router (because I tried two different routers)

You dont say what the problem is though..

I mean.. do you get any error messages or you just get the timeout error from IE?

using a DOS box, can you ping your router? and can you ping a website (any website)?

And if you leave the cards on DHCP, do they get an IP address in the range you're expecting?

What about the gateway address and the DNS addresses? Is the DHCP server serving them too?

When I use DHCP, NIC card getting default window ip address 169.x.x.x

Sorry about that, NIC card does not get ip address via DHCP

.. do you get any error messages

No.

No, it gets default window ip address 169.x.x.x

From ISP

So are either router configured to assign addresses via DHCP? That's kind of important.

Yes.

I just realized by help from others (credit goes to them) that it is a firewall issue (COMDO), although it was disabled (turn off) but that was not helpful , till I uninstalled it, and now every thing is fine.

Thanks Guys
