Well, the problem is that I am using a laptop that uses a wireless connection to connect to the internet. It was working fine, but one day it stopped working.

The main difference I noticed was that when I look at the network connections, the wireless part is working, for it describes as having an excellent connection. However, the local area connection says there is a network cable unplugged. I do not use a wired connection though.

I have tried many steps such as a simple restart, re-installing the wireless adapter, and trying to reset the ip address since I noticed that it was 169.254.XXXX.

However, every time I tried to reset the ip address, I run into the problem that it cannot do so because a network cable is unplugged.

Thanks for any help given.

A system which has a wired connection which is not being used (but has drivers installed) might reflect the network cable unplugged message.

The simplest solution for any device which is not being used and which is onboard...is to enter the BIOS/Setup and disable the device.

I don't do wireless...but the 169.254.XXXX normally indicates a networking setup that has gone awry. DHCP is supposed to provide an IP similar to 192.168.0.001 where it employed.

I suggest setting up the wireless connection anew.

You may give us more info by providing couple of logs....

1. Click Start>Run (Start>"Start search" in Vista).

2. Type in (or copy and paste):

cmd /c ping google.com>%temp%\$.$&notepad %temp%\$.$

and press Enter.

3. Notepad will open.

4. Copy all text in Notepad ([Ctrl-A], then [Ctrl-C]), and then post it (paste = [Ctrl-V]) in your next reply.

======================================================================

Go Start>Run ("Start search" in Vista), type in:
cmd
Click OK (hit Enter in Vista).

At Command Prompt, paste this:

You can also go to network connections, right click on "Local area connection" and select "disable"

At the very least, it stops that annoying icon from popping up in the systray telling you a network cable is unplugged.

You can also try disconnecting from the wireless, connect with a wired connection to check your settings, and then go back to the wireless.

Well, for the first one, it said:

Ping request could not find host google.com. Please check the name and try again.

Yes, I did copy and paste and still I got the same result.
For the second one, I got:

Thanks for helping, and I did try the other methods but still no result.

Regarding "Media disconnected" for wired connection, see what Louis said.

Wireless connection has "Default Gateway" value missing.

Make sure, your computer is set to obtain IP address automatically.
1. Go Start>Settings>Control Panel (Vista/7 users: Start>Control Panel)
2. Double click Network Connections (Vista/7 users: Network and Sharing Center)
3. Vista/7 users - From the list of tasks on the left, click Manage network connections.
4. For a wired network connection, right-click Local Area Connection, and then select Properties.
For a wireless network connection, right-click Wireless Network Connection, and then select Properties.
5. From the General tab (Vista/7 users: Networking tab), click Internet Protocol (TCP/IP), make sure it is checked, and then click Properties
6. Click Obtain an IP Address Automatically, and then click OK.

Try some more basic steps...

Turn off computer. Disconnect router, and modem from power source for 1 minute. At the same time disconnect ethernet cable as well.
Reconnect everything.
Restart computer.

If that doesn't work, bypass router, and connect computer straight to the modem.

If that doesn't work...
Go Start>Run (Start search in Vista), type in:
cmd
Click OK (in Vista, while holding CTRL, and SHIFT, press Enter).

In Command Prompt window, type in following commands, and hit Enter after each one:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
net stop "dns client"
net start "dns client"


Restart computer.

If that doesn't work...
Go Start>Run (Start search in Vista), type in:
cmd
Click OK (in Vista, while holding CTRL, and SHIFT, press Enter).

At Command Prompt, type in:
netsh int ip reset reset.log
Hit Enter.
Type in:
netsh winsock reset catalog
Hit Enter.

Restart computer.


If that doesn't work...
Download, install, and run WinSockFix: http://www.softpedia.com/get/Tweak/Network-Tweak/WinSockFix.shtml (doesn't work in Vista)
Restart computer, and check again.

If that doesn't work...
Download Dial-A-Fix (DAF) (doesn't work in Vista):
http://wiki.lunarsoft.net/wiki/Dial-a-fix#Mirrors.2Fdownload_locations.2C_and_articles

Have XP CD available in case DAF needs a file. Likely not!

Check all boxes on the screen (clear any restrictions if it shows any)
Then click GO!

When the entire page is finished click the HammerHead at bottom to go to the second DAF page.

Here, one at a time, do the below:

Reinstall BITS
Reinstall Windows Firewall
Repair Permissions
Reset networking

Watch for any File not found or other errors and make note as this may lead to the fix!

Restart computer.

Well, while doing the first step, I ran into something weird. Every thing was going great until the ipconfig /release part, in which it said:

no operation can be performed on Local area Connection 2 while it has its media disconnected.

If I connect the ethernet though, the internet does work.
