First: If you have a sales department, don't you have an IT department?
And if not, WHY not?

You will get the APIPA address b/e your DHCP server is not working properly. That can be your router or your DHCP server. If that server is within reach go and check if DHCP is running. Otherwise restart that service.

It might help of you could describe your setup more detailed. What kind of server, how many PC's, problem with all of them (apart from sales)...

How to find a IP address for my emachines laptop

go to start -- run and type in CMD
hit enter to open a black command prompt window

type in "ipconfig" without the quotes and hit enter. This will give you your IP address.

If you need the IP address from your provider that you are using out on the public internet, just go to and it will tell you what your external public IP address is.

I have a Dell Inspiron 531S. The internet was working yesterday morning, then last evening I could not connect. I contacted the internet service and they tried several things then said it was my network...

This solution is based on the assumption that this is your personal at home PC and not a member of any workgroup or on any connection that requires a proxy connection.
These instructions are for Windows 7 and are very similar to Vista, if your OS is XP then I'm sorry I don't remember where these settings are but they have similar names so you should be able to find them.

1) Check your internet settings, ensure that it is configured to "automatically detect settings"
>Control Panel>Internet Settings>Connections Tab>LAN Settings

Still not working?

2) Ensure that no alternate configuration has been input into your individual connection settings
>Control Panel>Network and Internet>Network and Sharing Center>Change Adapter Settings>Right click on connection you want to use left click properties. Everything in this dialog box should be checked. Doubleclick Internet Protocol Version 4 (TCP/IPv4) The tickbox next to "Obtain an IP address automatically" and next to Obtain DNS server address automatically" should both be ticked. Go to Alternate Configuration Tab: Should be set to "Automatic Private IP Address"


3) >Control Panel>Network and Internet>Network and Sharing Center>Change Adapter Settings>Right click on connection you want to use and left click "diagnose"

If we haven't got it yet let me know and with a little more information we can try something else. In my experience this solves most connection related problems.

Hope it helps,

The internal ip address (differentiates the computers on your network) can be found by running the command prompt (start --> run--> cmd or start--> all programs --> accessories --> command prompt) and then typing int eh following command: "ipconfig" (without quotes). It will be the set of numbers in the form 192.168.something.something

Good luck, let me know if you have any questions

No ip address

Network Card's driver is not installed. Check and install drivers from Device Manager Window.

IP Address can be assigned automatically(through APIPA/DHCP) or Manually.

There is no DHCP server, it takes the Automatic Private IP address(APIPA) or else get it from DHCP server by using "ipconfig" command
Steps: Start>accessories>command prompt>ipconfig /renew

Right click on My Network Places> Properties>Right click on Local Area connection>Properties>General Tab>select Internet Protocol(TCP/IP)> Properties>General> select "Use the following IP address> assign IP, Subnet Mask, Gateway and DNS> Press OK Tab.

Local area connection: 'Local only'

Does your department use DHCP? (It will automatically update your computer's settings when connecting)

If so, I would go into your TCP/IP Properties and make sure its set to automatic as well.

If not, you need to go into your TCP/IP Properties and put in the IP Address, Subnet, Gateway, and DNS servers information.

Also try opening command prompt and doing IPCONFIG /RELEASE then do IPCONFIG /RENEW.

Lastly, sometimes you can right click on the connection icon by the clock and do a repair, that will do pretty much the same thing, but sometimes works.

Trying to hook up lap top to wireless internet. Comcast tech says there is problem with IP# 169 which preceeds other numbers and needs to be removed for hookup. How can I accomplish this? Model #3150H

Usually you will have an IP address starting with 169 if the adapter cannot get an ip address from anywhere, it is an autmoatic IP address.

What operating system (Windows XP or 2000 or Vista) are you using?
