Gateway laptop was connecting to internet wirelessly, not now

what is the laptop's ip address when on wireless ? default gateway ? subnet mask ? when connected on wireless ?
what are these when connected to cat5 ethernet cable ?
Is the default gateway different ?
is the ip address within the network address ? 10.0.0.3 to 10.0.0.254 or 192.168.1.3 to 192.168.1.254 ?
the first three digits should the same
what is the wireless ip address is it the same as the network router or different ?
What is the dhcp leases are they conflicting with the main router and wi fi router ?

How many DHCP servers are there ?

Thank you for your kind words, we try very hard to resolve people's problems so a solution can be reached.

Ok. As per your statement your laptop is working perfectly , when you are connected your laptop with with the cable wire.So the network cable is OK. So you have to configured the wireless cable in your laptop when it is connected to your laptop. After connecting the cable wire to your laptop you have to findout the gate way of your ISP ( Internet Service Provider). To find out the gate way , kindly follow the following instructions.

First findout the IP address , subnet mask,and Gateway addresses of your ISP ( InternetService Provider ).To find out the above mentionedaddresses first open the control panel -> network connections -> local area connction -> properties -> Internet Protocol Version 4(TCP/IPV4) OR Internet Protocol Version 6 (TCP/IPV6)according to your ISP -> Properties

By the systematic selection as mentioned above you will get the IP address, subnet mask and Gateway addresses. Kindly note the Gate way address of your ISP. Then enter the gateway address in the browser and open the window. Then a control panel / a window will appear. It will prompt you to enter 1). user name, and 2) password. If you are having the user name and passwords provided by your ISP , kindly enter them in the window and click to open. Then the particulars of your ISP will be displayed in the window. Then click the wireless icon and click to enable. Hurray ! your laptop will work perfectly through wireless. If you are not aware of about the 1). User name and 2). password , you must approached to your ISP and try obtain the same for working of your laptop wirelessly. Provided , that you have to configure the wireless enabling for both the ethernet cables and there after save the changes , after finding the 'GATEWAYS' if both the the ISP's seperately.

check the configuration of your laptop. use another laptop to check the wireless configuration if its working in another laptop...check all possible setting of your laptop..make it fault all if needed

if you are trying through wireless, first unplug the wire from the laptop,

make sure that the wireless switch on your laptop is turned on.

click on start, control panel, network connections/network & internet/ Network and sharing center..

right click on wireless network connection Icon, if it says disable, it means it is enabled already.

then click on status..

from here the steps would differ from OS to OS

then click on Support tab (for XP)
check the address type, it should be "Assigned by DHCP"
and if you see the IP Address starts with 169., it is a bad IP and needs to disable the connection and enable it.

if the connection type is "Assigned Manually, right click on wireless network connection icon and click on properties and click Internet Protocol(TCP/IP) and click on properties, in this window, check the option "Obtain IP Address Automatically from DHCP"

click ok and OK ..

again right click on the wireless network connection icon and click on view available networks... click on your router name and click on connect..

now check the functionality.

if you are using windows 7 or vista,

click on status, click on details for the IP Address..

We see DHCP Enabled as YES or NO instead of "Adress type"in XP

if it says no, it means it is assigned manually. to change to DHCP , right click on Wireless Icon, select properties, click on IPV4 IP address and click properties, then select obtain automatic..

then try again..

hope this works,

Try setting the default gateway on the laptop to the ip address of your ICS gateway machine. Some routers separate the wireless and LAN connections on different subnets.

Try comparing your laptops ip information with that of one of the working wired computers. You can do this by going to Start up to run and type cmd then click "ok"

At the black prompt screen type "ipconfig" without the "".

You want to compare the IP Address, Submet Mask, and Default Gateway.

If one has an ip of 192.168.1.* and the other has 192.168.0.* then the wireless and wired are on seperate networks.

If the subnet masks are something like 255.255.255.0 and 255.255.255.1 they are on seperate subnets. Both should be fixable by putting in the same default gateway.

For example if your ICS gateway is 192.168.1.1 then set that as the default gatway on the wireless laptop. This can be done by going to start >> Control Panel >> Network Connections then right click your wireless connection and goto properties then double click on the "Internet Protocol (tcp/ip)" option. This will list all of your ip information (if its static) if its dynamic (ip gotten from router) you can still click "Use the following DNS server address" and set preffered dns to the gateway ICS ip. Or click "Advanced" and click Add under Default Gateways and add the gateway ICS ip there.

what brand of wireless modem you have, what os are you using?did you switch on the wireless in your laptop? sometimes we overlook the most simple things, it happens to me..
ok, you have to configure your laptop to connect to your wireless modem, how? just connect first your laptop with wire to the wireless modem, does it work? if it does work you can take the default gateway ip add from your pc by typing IPCONFIG on the command prompt , then type it in your internet explorer address bar.

example default gateway..... 192.168.1.254

and supply the username and password, you can now configure your wireless connection wep/wpa configuration.

if you can connect to the internet when you connect the pc to whe lan port , then your internet connection is ok and all you need to set is the wireless settings in the router.
connect the pc to the router with a cable .
then , Start-> Run-> type cmd-> ok-> type ipconfig-> enter-> look on the default gateway address -> type the numbers of the default gateway in the address line in your internet explorer-> there you should check , enable and or change the wireless settings.

Has the computer ever stayed on long enough to connect to the internet?

Is there a wired computer working when attached to the router?

If not, if possible please try to connect the laptop wired to the router as a test and tell me if it works.

I am trying to determine if your router works with the internet before considering the wireless connection simplying the initial problem. Once the router works wired is time to try the wireless. Once the wireless works unsecured you may want to change the router and wireless adapter to secure the wireless network. So this can be a three step process.
