i am well aware that this is a duplicate post but i made the mistake on my first post to put a own reply under it with updates of my situation wich removes the post from the posts to be answered :

On my laptop i am unable to connect to the internet since a few days.. the reason would be "unable to contact DHCP server"
i have a linksys network pc card..
if anyone might give me the exact instructions to follow i would appreciate

By the way i have TRied ipconfig /renew and release already.. and ping 127.0.0.1 to check.

Ty.

Is this a wired network card in the laptop or a wireless?

What is the desktop operating system?
It sound as if the received an IP address and connected to the Internet in the recent past. Did anything change, new hardware, software, update, patch since the last time you got an ip address?

nope we had some router probs in the house but all the other laptops are working again. except mine :s its a Card that you have to insert in a slot (bus?) its not in the laptop.

You may have tried this already but if you did not, let's see if the laptop can communictae in this network at all. Give it a unique static address address for your subnet. If you are unsure how please say so but from judging from your posts so far, you know how already. Once you apply the static ip, mask, gateway and dsn servers. Try pinging the router's ip. If you get a reply, try pinging one of your dns servers. If you get a reply, ping yahoo.com.

hmm i might know what ur asking but prolly in other words.. whats my static adress from my subnet? :s

i'm trying to ping stuff now

if you did not get an addres from the dhcp server you have an automatically assigned ip address 169.x.x.x or something like that.

You mentioned you have other desktops on the network. Get on one of those computers (a windows 2k or XP system) and open a command prompt by Clicking Start >> Run >> type in CMD >> then click run or open.
A small black and white command prompt window will open. Type ipconfig and hit enter. The results of this command will show you the ip address of that system the mask and the gateway. Post that information back on the forum. From that info I or another member can tell you what to enter for a static IP.

Double check the actuall physical connection of the laptop to the network switch too.

gateway is 192.168.2.1 nobody is going to hack me now ? i hope .. :s?
mask is 255.255.255.0 but thats not important. and my ip is something like 192.168.2.103
if ur asking me wich range the ip has to be i know that its 192.168.2.1-200

ping 127.0.0.1 OK.
Ping Router Negative
ping other desktop negative.
ping yahoo negative.. well.. :s

The information as you 've provided:

address: 192.168.2.103
mask: 255.255.255.0
gateway: 192.168.2.1

This is from the computer that connect any where or from another computer on your network?

If it's from another computer that IS working, then go to the computer that IS NOT and open the network properties and assign the following:

ip address 192.168.2.198
mask 255.255.255.0
gateway 192.168.2.1

dns 1 : 129.250.35.250
dns 2 : 129.250.35.251

The apply and save.

Ping your gateway address of 192.168.2.1
On the general tab of you local area connection properties (the same place you find the TCP/IP properties) there's a checkbox near the bottom with the following text next to it, "show icon in notification area when connected". Check the box. A new icon will appear on the bottom right of the screen. If there is a physical connection the icon will consist of two little computer screens ( I know you have seen these before). If there's no connection there will still be two little computer screens but there will also be a fat red X over them. This means there is no physical connection - this would have to addressed first as no amount ip address changes will cure the problem.

There is a physical connection. but when i ping my gateway it time-out..

i have tried my card on other laptops and it worked well -_- .. i guess it getting complicated now.

Trying the card in another laptop was a very good thing to do. Configrming that the card is a working one narrows the possible causes of the problem. Now the focus can be on the laptop and more specifically - the drivers.

But before going to this, because it can get messy, when you tried the card on another computer did you connect it using the same network cable? If not, use the same network cable (patch cord) that the "bad" laptop computer was connecting to the network with.
