My newly purchased dell inspiron 560 will not connect to the network due to "an invalid ip address". 10 other computers are working fine on the network. Any solutions?

Internet Protocol Address is wrong Call your Internet Provider

Limited connectivity
If you get a 'Limited connectivity" on you wireless connection on your laptop, it means that the wireless card on your laptop probably did not get an IP address from the wireless router.
To fix this problem, right click on the wireless icon on the Task bar and then click Repair.
This will force the wireless router to issue a IP address to the wireless card on the laptop.

Open a command prompt:
Start>All Programs>Accessories>Command Prompt

Once in there, type this exactly without the quotes "ipconfig /release"

your ip address will come up 0.0.0.0

Now at the blinking cursor type in exactly without the quotes "ipconfig /renew"

Now you should have an IP of 192.168.xxx.xxx, or 10.10.xxx.xxx or even something different depending on your network.

If you come up with an address of 169.254.xxx.xxx, You' should restart the modem and the router. To do that first power off the router, then the modem. turn them back on in reverse order.

You should be able to connect after that.

Hope this helps

Either the network requires you to manually configure your ip settings(unusual but not unheard of) or your wireless adapter is not set to get settings from DHCP. Check to verify that your wireless adapter is set for DHCP and if this is correct then you'll need to contact the administrator for the wireless AP and haver them check their settings.

A hardware error usualy indicated a bad network cable or a bad network card. Have you tried using a different Cable?

Connect it directly to the modem with the ethernet cable first...Windows will configure the Dell...then the wireless should work.

Hi there try this first look for your network connections and right click on it and select repair this connection and select ok and see what happnes it should repair the connection and give you a aquirring network address if not try to move the laptop to a different area and see if you get a better signal ok

reset the modem and the wireless router by powering them off for 30-60 seconds, then plug power back in. Wait a minute or so for the devices to reset then go to the PC and try to connect again

Good luck

On the Support tab - what does it say the "Address Type" ?
If its DHCP then check that on the TCP/IP properties;
If on "automatic IP address" then it wont take any entered IP address.

Do not put any IP address.

Check that "Obtain an IP address automatically" is checked and also "Obtain DNS server address automatically" is also checked. On wireless network tab check "Use Windows to configure my wireless network settings".

On preferred network check that your wireless network is there, if not add it and move it up

Here's How:

1. Click the Start menu button on the Windows taskbar.
   
   
2. Click Run... on this menu.
   
   
3. If the computer is holding a current IP address, type 'cmd' (without the quotes) in the text box that appears. A command prompt window appears on the screen.
   
   
4. Type 'ipconfig' (without the quotes) to view the status of the computer's IP address(es).
   
   
5. If the computer is holding a current IP address, type 'ipconfig /release' to let go of the address.
   
   
6. Type 'ipconfig /renew' to obtain a new IP address (whether or not the computer is holding a current address).

Tips:

1. If it is not necessary to view the current IP addresses on a computer, simply type 'ipconfig /release' or 'ipconfig /renew' (without the quotes) in the text box that appears in Step 3.
   
   
2. To bring a computer back onto the network after moving it to a different location, or experiencing an unexpected outage, first release, then renew the IP address. Computers on DHCP networks often (but not always) re-establish network connectivity automatically.
