Hi I'm in dire need of help!
Just yesterday I was on the internet on my laptop when all of a sudden I a message appeared saying I had limited or no connectivity although I was still had full excellent signal. The problem is not with my router or service provider as my flatmates are still able to successfully connect to the internet through the same router so the problem must lie with the settings of my own laptop. I have tried to "repair" the problem but a message appears saying I am unable to renew an IP address. I am completely lost without my internet and have little knowledge of computers. I have contacted Virgin Media, my internet provider, but they say there is nothing they can do because the problem is with my laptop and not the connection.

Does anyone one how I can resolve this issue quickly?:confused:

Quickly? Probably not because it's a cryptic message. Usually it does indeed mean that you cannot obtain an IP address. Does your laptop have a static IP? Did they recently rebuild the network and set an IP range that does not include yours?

Eh I'm not sure if I have a static IP, I wouldn't have a clue how to find out! Its possible that they hve recently rebuilt the network as the company has been rcently been taken over.

In that case go and talk to the IT department.

Its my home laptop, I donlt have an IT department to ask for help

What version of Windows?

Windows XP Home Edition

Go to Start/Run and type CMD. In the command window that opens type:

IPCONFIG /ALL

Make a note of your IP address. Then type

IPCONFIG /REFRESH

Make a note of what the results are. See if your connection improves and report back. Also make sure you do a virus and spyware scan.

I don't understand how the company being taken over has anything to do with your laptop problems. Is it your personal laptop or the company's? Is it a home network that you set up or is it the company's?

Apparently my IP address is 0.0.0.0

When I typed in IPCONFIG/REFRESH it said "error: unrecognised or incomplete command line"

Its my own laptop set up in a home network, it has been working fine with no problems for about 8 months and then all of a sudden I have 'limited or no connectivity'?! I donlt understand it

Ok, That you IP is all zeros means that your computer is not getting to the router. Sorry, I gave you the wrong command. Try:

IPCONFIG /Renew

If that doesn't work, try Pinging your router by typing

PING 192.168.1.1

That's usually the router address.

OK, IP address is now coming up as 'Autoconfiguration IP Address 169.254.166.63'

When I typed IPCONFIG/Renew, it said "no operation can be performed on Local Area Connection while it has its media disconnected. An error occurred while renewing interface Wireless Network Connection: unable to contact your DHCP server. Request has timed out"

I then tried the ping thing, but it repeatedly told me 'destination host unreachable'

Here's a good read: Solved: IP address issue - Tech Support Guy Forums (http://forums.techguy.org/networking/469410-solved-ip-address-issue.html)

Ok, The problem is your system is not connecting with the router. So now you have to figure out why. The first thing to check is whether youa re connecting to the correct network. Right click your network icon in the tray and check the status. Under Network, it gives the SSID of the network you are connected to. If that's not correct. Use View Available networks and connect to the correct one.

Pssst after a quick reread this memebr is in UK on a Cable connection.
Now are you using USB or Ethernet connection (Normal telephone like cable) ?
Have you got anything else connected to your cable modem ?
If you have how does the laptop connect to the cable modem ?
Do you have a router of any type ?/

Eh all I know is that its wireless. There's an ethernet cable but that's plugged into the router

Rite, I'm not sure what SSID is, but the network I am connected to is called MYWAN which is definitely my network

Yeah there's a white cable also plugged into the modem but I think that is the phone line or something. Then there's an ethernet cabel running between the modem and the router

Do you know if you mates changed any of the security settings on the router? If not. I would try removing the Lan Connection (in Control Panel), rebooting and recreating it.

I'm don't know if they have about I seriously doubt it as they're more clueless than I am when it comes to computers. I was at home alone when it stopped working for me so I doubt they had anything to do with it. How do I go about removing and recreating the lan connection? Is LAN a cable connection? Will this make a difference even though I am on a wireless connection?

First I would try doing a System Restore to before it stopped working.

If that doesn't work, under Control Panel, select Network Connections (you may have to select Network and Interent Connections first. That should give you a list of connections. One will be Wireless Network Connection. Delete that then reboot your machine and run the Connection wizard.

It would only let me disable the wireless connection,not delete it. But I have rebooted and its still not working
