Re: manually assigned IP setting lost


You have to uninstall the LAN card manually from the safe mode...
After that restart the Laptop installed the LAN card by proper driver …

Then go to command prompt type IPCONFIG
You should get the IP it 169.XXX.XXX.XXX this is by automatically assign by windows...

Right click on the network /right click on local area connection/click on TCP/IP properties then click on use the following IP type which IP you want to specify …

Click on ok and close the local area connection windows…

Again start command prompt type the same command i.e. IPCONFIG

Now see which IP address you have set on your card is their or not…

If you not seen the IP Address which you set then type the command i.e. I IPCONFIG /renew or IPCONFIG / release...

Then again repeat the above setting...

When I have turned on my Acer Aspire 6920 computer this morning it just goes to a screen that says the following Client MAC ADDR : 00 A0 D1 A8 32 D3 Check Cable COnnection PXE-MOF: Exiting Intel PXE ROM...

The first bit with the MAC address is there because it's trying to boot from LAN and it is exiting because no IP address is assigned to it by the DHCP. If your laptop is connected to a network, you can use this feature to image the laptop across the network with an imaging software like Norton Ghost.

The last bit, "Operating System Not found" means that you do not have Windows or any other operating system installed on your laptop. At this point, you can either reinstall your operating system or use the recovery disc that came with the laptop to restore it back to it's factory settings.

When i plug my laptop into my router it does not connect to the internet

first you have to be sure that your Lan card is installed..
for that just take a look into the device manager get there click right on the my computer icon ..than choose properties..and hardware ..and then device manager ..In the window for devices..take a look over the network area..and see if your card (LAN network adapter) ok ..if it is in yellow with a ask sign on it will need to install the driver for it again ..
If you have a motherboard drivers disk ..get it from there if you not the support site for Compaq and download it ..
here is the link ..
here is the link I already selected your model all you have to do is to select the operation system you use..and choose from the list the LAN adapter driver .;download it and run it to install..
at that moment you know for sure that you have a functional lan card on your computer ..
now connect teh cable to one of the router's ports..and open the lan card from the 2 monitors like icon in the tray sistem ..local area connection ...
click properties in the window..and in the list that on TCP/IP protocol ..
it will open a window that has 2 options is to obtain an IP address automatically ...and second is to use the following Ip addresses..
In your case use the fist one ..and see if the router will assign the IP addresses necesary ..and will conect it ..if not will have to configure it manually it follows..
the ip address will be the routers Ip but the last digit you have to add the number of teh port ..for example if it is plugged into the number 2 port ..the router 's .. so that the port's IP will be ..
the subnet mask will always be
and in this moment the default gateway will be the router put in the router's IP ..
for the DNS servers let it take them automatically from the routers settings cause they will be the same ..(the ones you used to have from the provider and insert on the connection when you didnt used a router ,..
this is about all that you have to know to connect it ..
try first to obtain IP automatically ..cause this is the default way to do it ..

LAN connection won't work, but wireless does

It sounds like the LAN card may be going bad. You can see if manually setting the IP address in the settings of the LAN card will work. If that works, then the card's routine for negotiating IP address assignment is corrupted. You maybe able to get some more useful life out of it by doing this until you can replace the LAN card itself. If you need more instructions on how to set the IP address manually, reply back and I'll try to step you through it.

Have connectvity on laptop through router but no internet. firewall off and ipconfig reset, but still no internet through ie or firefox?


Could be a problem with your LAN card or interfering software, if others accessing your network are OK. (Test first). If others are experiencing the same, reset your router and contact your provider, if necessary.

Try these suggestions ... perform the next if each does not work:

Move your laptop next to the router to see if distance is a problem.

Connect your laptop to the router with an Ethernet cable to see if the wireless function is not working.

If you have an anti-virus software package installed, disable for testing purposes.

If you have installed / updated your computer and now Internet doesn't work (worked previously), remove or uninstall.

Go to Device Manager, find your LAN card and update the driver.

Go to Device Manager, delete the LAN card, reboot your laptop.

Hope these suggestions help.

I formatted my system and reinstalled Win XP on it, but now I could not use wireless to connect with internet

Make sure you have Wireless network adapter driver installed.

Manually assigned IP address and DNS address as earlier (if your IP setting is not automatically assigned by DHCP server).

If you are using router set your Router IP address as your Default Gateway Address.

If you are using Internet through a Proxy Server then Open "Internet Explorer ",
Click "Tools",
Click "Internet options",
click on tab called "Connection",
Click "Lan settings" Button.
Remove "Automatically detect settings".
Tick "use a proxy server for your LAN....."
Type the IP address of your Proxy Server and the port no.

It will work.

My laptop acer extensa 4220 can't access the wireless with its driver,why it is?

Are you trying to connect to your wireless router or to a Wi-Fi hotspot?

To connect to your wireless router, it needs its wireless settings configured and also the wireless card in all the laptops and or computers needs to be configured with the router’s wireless settings. Then the laptops and desktop computers can communicate with your wireless router.

To set-up and secure the wireless router from unauthorized access, follow these steps: -
1. Connect the wireless router to your computer with a LAN cable.
2. Start your browser and enter the router's configuration URL IP address.
3. Enter the router setup, login and password
4. Change the admin password
5. Go to the wireless settings and change the default SSID and turn off SSID broadcast.
6. Setup encryption key the strongest is WPA2 (if not then WPA).
7. For further security measures - turn on MAC address filtering and enter the MAC address of the wireless cards on the computer/s you want to connect to this wireless router.
8. Record the settings you have made and keep it in a safe place and Save the settings.
9. Configure the wireless cards on the computer/s with the SSID and encryption settings of the router.
10. Remove the LAN cable between the router and the computer then the computers should be able to connect to the router wirelessly.

Cant connect laptop to cable modem

OK based on the IP address you've given me I can tell that your network card is not getting an IP from the cable modem. The IP you have there is automatically assigned by windows in the absence of a proper DHCP server.

You have 2 options now you can try to manually assign the IP address and connect to the modem or if u have the CD that came with it you can connect to it using a USB connection (most modems have a usb port) and configure the modem manually to give you an IP or at least see what address range it is using and configure your PC to suit.

If you don't have the CD and USB and you want to manually assign an IP address to your PC most modems tend to use 1 of 3 address, you can try either:
to connect to the modem (if you use a ping command from the command prompt with any of the above addresses the one that replies is the ip of ur modem)

and manually configure your PC network card with either

Its a little technical i know but you should be able to do it
Hope this helps you.

If this doesn't work we can try a "tracert" command next to see if we can determine the modem IP

Wireless connection

First I will confirm what you've posted.

Before going to your friends house you used to connect the laptop up via the network cable. Since youve tried your laptop on your friends wireless it no longer allows you to surf the web via the wireless nore the wired connection?

To me it sounds like a possible mis-configuration between your laptop and your linksys router. Depending on what operating system you are using you need to get into your network connection settings (usually in control panel) and either set the TCP/IP to automatically obtain ip address or set it correctly.

If you have never had to configure this in the past ensure that obtain automatically is set.

Gateway laptop was connecting to internet wirelessly, not now

Check that if there is Static ip configured on your Lan-Card...

if yes.. then you need to configure the IP addresses manually for W-LAN as well.

One more thing; if Lan-card is not configured with static IP then

make sure your W-lan IP seting is on "obtain Ip automatically"

Here is the way to do this....

Click on the start orb to open a list of programs and content. The start menu has been replaced by the “start orb” which still gives you the same functionality as the start button from previous OS versions, but consumes less screen real estate.
Right click on “Network” and go to properties. That opens the “Network and Sharing Center” which is your central office for anything pertaining to (just as it says) networking or sharing resources.
On the left hand column you want to click on “Manage Network Connections.”

This opens the Network Connections Window which you will find familiar to Windows 2000/XP. It will list all of your NICs or Wireless Connections.
Right click and go to properties of the connection you would like to statically assign. You will now be prompted for an administrative password. This is part of Microsoft’s new User Account Control (UAC) which will help unauthorized changes to your systems.
Once you have authenticated you will see the properties of the selected network connection.

The properties screen is very similar to what you’ve seen in the past, but one thing you will likely notice is by default Windows Vista supports IPv6. If you’re on a corporate or government network that is running IPv6 you can fill in your IP information there.
Otherwise, you will select Internet Protocol Version 4 (IPv4) and click properties. Now you will be able to Choose the option "Obtain Ip adress automaticlay"

Close the Network Connections Window

Let me know if this helps.. Good luck...
