I have a problem with my internet, it has been working fine for two years on my laptop, but suddenly this week it randomly disconnects, does not let me sign into windows live messenger, is very slow at points, and at other times it works fine, and then just goes wrong again. I have no idea what the problem is as it has been working fine for like two years now. When i followed this tcp thing, my vista version doesnt have that option, so i have no idea what to do.

Many thanks in advance as i need this internet to work for my education aswell as social life!

Dirge,
Your tip saved me, but in my case, specifically, it only worked using both automatically (IP address and DNS servers). Thanks!!

TRY THIS: It worked for me:
---In vista (x32 bit) -probably works very similarly in vista, though i think this is more of an issue in vista.

Before doing anything, bring up your ip settings for reference. To do this:
-Right click command prompt in start menu-run as administrator- type: ipconfig.
(This will display your computers and routers actual ip settings.)

My symptoms were strange. The wifi network had no changes, and was working fine on other machines. On the vista laptop, the wifi card received the signal, and even gave access to the internet. While Google loaded with no problem, and most searches went just fine, many many sites 404ed, and would not come up, and the connection was rather weak and finicky. Also, i got the following message from my diagnosis.

If you have a similar issue, PLEASE ATTEMPT THE FOLLOWING:

Control panel- network and sharing center-view status (of the troubled network... usually the wireless network)- then click diagnose...

At this point, if the problem persists, you will see the message:

"Cannot communicate with (Primary) DNS server (IP ADDRESS). "
"Network diagnostics pinged the remote host but did not receive a response"

Follow several steps to solve the problem completely. First:

Return to your -view status- window you opened earlier, and instead of clicking Diagnose, -click properties (you need administrative access)

-Under the networking tab:
-In the "this connection uses the following items:" list, select:
-Internet Protocol Version 4 (TCP/Ipv4).
-click properties
-under General tab there are two sections, one for setting the IP and one for the DNS.
-set the DNS to "Obtain DNS server address automatically."

THAT SHOULD FIX YOUR PROBLEM. Click OK, and return to the status, and:
-click Diagnose- thr problem should be resolved. If it is not:

-select "Use the following IP address" and enter your information from the command prompt (IP address, subnet mask, and default gateway) Leave the DNS on automatic.

Problem should be solved. If not, good luck! I highly recommend you look through windows help (aka not online, just your on-board help system from windows. That is how i figured out how to change the settings that fixed mine.

I had set up access restrictions on my router to allow internet through a specific MAC address for my laptop. With my new Vista laptop giving this problem initially I had forgotten that. Now after adding new MAC address I am back on internet. Hope this helps someone.

In the TCP/IP settings, I changed the DNS IP addresses. I got the correct ones from my other laptop. (Do ipconfig /all in the cmd prompt) Looks like the DNS addresses got messed up on my vista system
