My laptop connects to my wireless network at university, but will not connect to the network at home. I have tried repairing the network connection,but it still says signal strength excellent and is aquiring IP address. I have tried setting the IP address instead of it aquiring automatically- this seems to connect for a few seconds and then disconnects again. I have a different laptop which connects to the wireless network fine. When my laptop is aquiring the address automatically and I do run, cmd, ipconfig/all it states:

Re: Laptop can't aquire IP address
This sounds to be a compatibility issue with either the wireless software or wireless card. Check to see if there are any updated drivers for the wireless card at IBM's support site. If there aren't any or the card still doesn't work after the updated drivers are installed, then you might try a different/newer internal wireless card, or a universal external wireless card for use with your home system.
I had the same problem, went to Microsoft and found this solution on line. 1. Click Start, click Run, type %SystemRoot%\system32\services.msc /s then click ok. 2. Double-click Wireless Zero Configuration. 3. In the Startup type list, click Automatic (if it shows Automatic already, change it, then put it back to Automatic, that will activate the Apply button) then click apply. 4. In the service status area, click Start, and then click OK.
That fixed it for me after fighting it for about a month.

If you get a 'Limited connectivity" on you wirelessconnection on your laptop, it means that the wireless card on your laptopprobably 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 thenclick Repair. This will force the wireless router to issue a IP address to the wireless cardon the laptop.
Every Windows Operating System after Windows 98 can share its Internet Connection using this Technique. Microsoft defines this technique as Internet Connection Sharing (ICS). But setting ICS is very obscure to most of the users. This comes very useful if you live with your roommates and you guys have single internet source like a USB modem Connected to one laptop only. Using Internet Connection Sharing(ICS) that laptop can Broadcast its Internet to other laptops in the room. Technically, the range of a laptop's WLAN adapter is around 20-25 meters. So it can easily handle near by rooms also. This can also be done with a PC having a WLAN card. To setup and broadcast your internet it is mandatory that you are accessing internet using anything other than Your WLAN card like a USB modem, Ethernet etc. This is because your Wireless adapter(WLAN) will be used for Broadcasting your Internet connection to your friends. Server laptop:- Laptop with Internet Connection.Client Laptop:- Laptops accessing the internet of server laptop. Follow the steps to share your internet connection..here it goes:--
Open the "Control Panel" of the laptop that is accessing Internet and go to "Network and Internet" then "Network and Sharing Center".
On the right side of the "Network and Sharing Center" click the "Change Adapter Settings" and you will see all the available network adapters in your laptop.
Now Right-Click the adapter through which you access internet and click "Properties" option. The properties window will open.
In "properies" Window click the "sharing" tab check "Allow other network user to connect through this computer's Internet connection"
In the sharing tab, Select "Home networking connection" type as "Wireless Network Connection" click "OK" and select "Yes" to the Confirmation warning. see above image.
Now Right-Click the "Wireless Network Connection" in "Change Adapter Settings"and Open Its Properties.
In "Wireless Network Connection Properties" Double-click the "Internet Protocol Version 4(TCP/IPv4)" and select the "Use following IP address"
Enter the IP address as "192.168.000.001" and "Subnet mask" as "255.255.255.0"
Leave all other fields blank in Server laptop, which has access to internet.
Now setup a wireless "ad hoc" computer to computer connection using "setup a new connection or network" in "network and sharing center" and Name it as anything like "Internet_sharing".
Now bring other laptops that will use the Shared Internet connection.
Open "Change adapter Setting" (Described in step 2).
In "Change adapter settings" Right-click "wireless Network Adapter" and Click its properties.
In "Wireless Network Connection Properties" Double-click the "Internet Protocol Version 4(TCP/IPv4)" and enter following IP address:-
IP address-"192.168.000.002", Subnet mask "255.255.255.0", Default gateway-"192.168.0.001" and Preferred DNS server: "192.168.000.001".
Use the same step from 11 to 15 to connect other laptops and Increase the IP address by +1. Ex- 192.168.0.3, 192.168.0.4 & so on. Rest of the settings like Default gateway etc will be same on all laptops. Only the server laptop will have blank entries in these settings.
Now connect all the laptop with the Wireless network(ad-hoc) named "Internet-sharing" that you had previously broadcasted in step 10 in server laptop.
Now in the server laptop, disconnect and then reconnect the internet connection(This is a necessary step for Internet Connection sharing(ICS) to work).
Now access internet in all laptops...ENjoy.
Note:- For Advance Users.. this information is necessary only--The IP address of server laptop work as the "Default gateway" and Preferred DNS server of Client laptop and on server laptop these fields are blank. Use same series of IP address as used in the server. please vote if you found this helpful..--Abhishek
There is a wireless card on it. You can use the Connect to option of your Start menu to search and connect to a wireless network connection in a public wi-fi hot spot such as starbucks. If you need to set up your home wireless network, you can use your own wireless router connected to your modem and set the network ID and password by connecting your laptop to it and open the web page with the URL of the default IP address of your wireless router and configure the settings. Use DHCP on your wireless router and your laptop TCP/IP configurations (Shown as Automatic IP address). Then you can use the connect to item in the start menu to connect to the network of your wireless router (according to the network ID you just configured). If there is a switch on your laptop to turn on wireless card, move it to turn on wireless. See the edge and the bottom of your laptop to check about that.

ok. try this:
open a computer on your network that connects to the network. start -> run -> type cmd and click enter.
then type ipconfig /all
then open your laptop.. go to local area connection and click properties.
click internet protocol on the list and then properites.
click on "use the following ip"
and on the three text boxes below type the same settings as the ones that appear on the pc that you did ipconfig /all. the only differnt will be the ip address. if the pc is 192.168.0.105 you should put 192.168.0.106 or something else.
do the same with dns server.
click ok to close all the opened windows and check the new ip of the laptop
try resetting the router to factory settings, it may have been set to allow only 2 or 3 wireless connections, just take a pen and hold it in the reset hole on the back of the router till all the lights blink and it restarts
You may be getting a little mixed up; the SSID is the dispayable name of the router over a network and the code you may be refering to is the WEP or passkey for security.
First go into your routers settings and ensure that the DHCP is enabled to automatically give the laptop an IP address.
Check your laptop wireless adapter/reciever is set in the properties to obtain IP adress automatically.
Turn off any encryption you have running on the router and restart both router and laptop.
When laptop boots it should again find all the wireless networks in you locality, then click on your network and click connect.
If all works fine go into router again and then set up security key and note whether it is an 'open' or 'shared' network access as you may need to input this into your laptop if it is unable to reconnect after the restart.
Also if your wifi signal is relatively low, it will not allow a connection to the internet as it is unable to send data at a low signal rate.
If you originally ran the router via an RJ45 network cable, you may need to clear the dns from your laptop, click Start>Run, then type ipconfig /flushdns and restart your laptop to give it a new ip address and dns address.
