ok my networked laptop was jsut working fine and one day it just stopped working!!
i didnt change anything at all..
ok so looking at the ip address which does not start with 192.168.x.x and the sub net mask is also 255.255.0.0 it seems that lapop is catching its own ip address right. also dhcp is enabled. i have cable connection... now pls pls someone help me out here.. i tried everything..even assigning the ip and subnet mask manually but even then it still doesnot work.
thanx in advance

if the network is setup right, allow the lapper to get the dns automatically.

First why don't you list what type of hardware your using (router) and how everything is connected. Did you purchase a static IP address or are you letting the router hand out dynamic IP addresses to your computer(s). I know you said you have DHCP enabled but I just want to make sure.

Have you upgraded anything lately or installed anything? Do you have a software firewall running?

"ok so looking at the ip address which does not start with 192.168.x.x and the sub net mask is also 255.255.0.0 it seems that lapop is catching its own ip address right."

Please explain. Does not start or does start, and catching its own IP address?

What is your IP address, Subnet, and most importantly your Default Gateway. Your DG should be the IP address of the router. This is the gateway to the Internet.

What????? What is a lapper? As usual your advice is fantastic. I was wondering when I was going to see that web page again. Man, I hope you’re getting paid from them.

rogers cable modem is connected to "microsoft" router, which is connected to desktop and to "cable free" net balster which connects to a laptop via a wirless "cablefree" card.
my DG is :192.168.2.1
and subnet mask is 255.255.255.0
and the laptop is catching its own ip addres which seems tot he problem..
also wht does lapper mean??

I think "Lapper" is uppercrust's attempt at inventing a cute slang word for "laptop". Must be a practicallynetworked.com thing.

Anyway, I'm guessing that the IP address your laptop is "catching" is 169.254.x.x? Details are good. If you think it's important to tell us that your laptop is getting an address, why not tell us what the address is?

If so, that just means your "Lapper" (tee hee!) isn't able to lease an address from the router for whatever reason. Troubleshoot the physical connection first, then the TCP/IP stack on your computer. I'm sure someone will be along shortly to help with the specifics of doing that. If not, I'll be home in a few hours :)

From my pervious post,

"Have you upgraded anything lately or installed anything? Do you have a software firewall running?"

Thank you for the info but I still need to know the IP address of your computer. Is 192.168.2.1 your routers IP address?

"and the laptop is catching its own ip addres which seems tot he problem.. "

Still have no idea what your talking about.

Are you having problems with the wireless computer or the wired computer? You left that out of your first post. That is very important. More information you give us the better we can diagnose your problem.

These are the questions you need the answer.

1. Which computer are you having problems with (wired or wireless, and what is the OS).
2.Have you upgraded anything lately or installed anything when your connection went down? Do you have a software firewall running?
3. What is the IP address of your router?
4. What is the IP address, Subnet, and Default Gateway for the problem computer.

Lets start there and if you don't know how to get any of this information that I'm asking for don't worry just ask and I will tell you how to get it.

1)Very true, believe the same as your computer would be catching an ip address of something starting like 169.254.x.x.
2)Is the computer set as dhcp client and the router as dhcp server?
3)Most important is that what is the ip address your computer is catching on its own. You haven't mentioned it yet.
4)Would you mind sending the output of "ipconfig /all" (without brackets... :-)) from that computer.
