The best way to check if the computer can access to Internet is to boot the computer to "Safemode with Networking", to do so, restart the computer and as soon as it restarts keep on tapping F8 key, now select "Safemode with Networking" from the Advance boot menu. Try to connect to internet. If you are able to connect to Internet then the issue is with the firewall on you computer, contact the firewall manufacturer or settings. If you are still unable to connect to Internet, then the internet setting are not correct, you may need to contact the ISP.
All the laptops available in market have built in wireless 802.11 b/g/n or 802.11 b/g/n Bluetooth® wireless networking. It means that you can access the internet via Wi-Fi or through Wi-Fi hotspots. In wireless connectivity you do not require the wired connection to access the internet. In home you can connect the laptop via wireless connection using the home networking router available in market. The advantage of wireless connection is that you can use the internet in your home anywhere with in 100 meters of range with proper wireless signals.You will require to get the internet connection from the ISP(Internet Service Provider).

DNS Error Fix
In most cases, a DNS error just means that the computer is facing
connectivity problems. This could be happening for a variety of reasons,
especially if you are connecting to the Internet via a wireless
connection. Since DNS transforms the website URL into a numerical IP
address, without the DNS functioning properly, the Internet connection
will be quite useless. There are a few solutions to this problem though,
and none of them are too complicated in nature.
Locate the networking icon on your taskbar (or visit the
networking tab from your 'Start' menu), and right click on it. Now
select the 'Repair' option. This should be able to fix elementary DNS
Go to the 'Start' menu and select the 'Run' option. Now type
'ipconfig/release' and hit 'OK'. This will release your old IP address.
Now you need to type 'ipconfig/renew' and hit 'OK' in order to renew
your current IP address.
You even have the option of entering your own DNS settings. If you
are using a local wireless connection, you will be informed about the
preferred DNS and the alternate DNS. You can alter this setting by going
to the 'Properties' of your network connection.
You must also check if all the cables and wires are connected
properly. If nothing works, then try using a different machine with the
IP addresses are generally assigned when you connect to another networking device such as a router, switch, or modem. You should first go to your Network Connections and right click on your networking device and click on properties. Click on Internet Protocol (TCP/IP) and hit properties. Then click on the box that says Obtain IP address automatically and Obtain DNS server address automatically. Now when you make connection with the router, switch or modem it should assign you an IP address. If this doesn't happen then you need to check your network cable, or wireless log in proceedure to find out why you're not connecting. These rules aren't for all systems. Some ISPs may require you to put in DNS servers and IP addresses. If the above doesn't help then contact your ISP to find out if there are specific settings. You can also view your Network Configuration settings by going to "Start" > "Run" cmd then in the window type /ipconfig /all. If you're connected properly you should have IP address, default gateway, DNS server and DHCP servers.
I would connect it to the router using a lan cable to verify that it will get a IP address and connect to the internet. Write down the IP information and make a static wireless connection with that info. It should work hardwired and wirelessly with this info. If it doesn't work wirelessly you may have a bad wireless card or you may find that their is already conflicting static IP info in the connection that has to be removed. Make sure that on your internet protocol (TCP/IP) properties that you have selected "Obtain an IP address automatically" and Obtain DNS server address automatically". Clear any settings that you may see there.
Chances are your internet connection at home differs from your "out and about" settings.
In IE go to tools + internet options + connections + lan settings + automatically detect settings. Try your browser again.
The other place where you might be able to fix your problem is within your network connections (Network Places + Network Connectons). Right click on your LAN or Wireless Connection (whichever you connect to the web with) and choose properties - scroll down to TCP/IP properties and double click on it. If you see a bunch of numbers displayed this is why you have a problem. Those numbers define your local or business network and are what is referred to as "static" ips. You can fix your connection problem by choosing obtain an IP address automatically (and the same with the DNS entry) but if you are using these settings on your internal network you are going to have problems.
Write down the settings within your TCP/IP connection (if you need to change them and so you can put them back later if necessary) and choose the automatic settings option.
hi i would suggest to access your routers setuppage and set the channel to channel 11.
make sure also if your wireless network is secured, type the correct key those things are case sensitive.
to access the routers setuppage go to a computers that is connected to your linksys router (wired) then launch IE on the address bar type 192.168.1.1(this is the routers ip) then it will ask you for username and password for the username dont type any thing for the password type admin.
when your on the setuppage click on wireless tab. while on the wireless page set the channel to 11.
after that click apply or save settings on the page.
then after that try to connect to your wireless network on your laptop.
for further help you can call linksys hot line 1800-3267114
they will surely help you with this.
assuming you have set up the router to enable DHCP which automatically detects pc's and assigns an automatic ip address, and assuming you are using XP and not Vista, although the workthrough is similair; go to open internet explorer>tools>internet options>connections tab and ensure that never dial a connection is ticked, then apply and exit IE
Next go to control panel>network connections, double click your wireless connection icon, select the TCP/IP line and click properties, then make sure obtain an ip address automatically is ticked, apply it ok, then open IE again and click the refresh button a few times.
