Re: Internet switches off
First you must be using a wireless connection, if this is so reinstall the drivers for the device. If you are using a hard wired network connection, you can go into device manager and disable the wireless network. In any event the problem is the drivers are either not installed or the wrong drivers are installed for the wireless network. BPCS

It may be the device you are trying to connect. shut down everything, unplug , remove batteries, plug in the ISP model, allow the self test, plug in the wireless device, allow it to self test, plug in, reboot the device, laptop, desktop, ipad, phone, whatever. You say you can connect using a Ethernet Cable? Just no connection wirelessly?
The error is related to your network interface card. In a lot of laptops this is integrated to the motherboard and can't be switched out at home. You will need to take the laptop in for service to have the card replaced.
try this: click on start then click on run then type cmd and click on ok a black screen will show up type ping google.com if you get a message that says "ping could not find host.." then it is a dns problem if so type ipconfig /flushdns, that should helo you. if the message after the ping is different, like request timed out, then you have communication to your router, but the router have no access to internet, check the configuration of the router.
First who is your service provider?
Can you connect to the internet if you directly hook your modem to your computer.
1>If so connect your Modem to your router on the colour code slot on the router which says modem
2>Connect a cable from the router to your computer
3>The lan light on the router should be turned on
4>Check wether your lan says connected . To check that click start-> control pannel -> network connections
5>If it says connected try internet explorer settings
6>If it says limited or no connectivity
Click start ->run -> cmd->ipconfig
7>It should say ip address as : 169.254.x.x.
8>If so type ipconfig/release
9>It shoul say ip address: 0.0.0.0
10>Type ipconfig/renew on command promt
12>Disable and enable lan
Let me know if this helped and also if you dont what kind of messages you get .
Let me try to solve this. Please try to see if the wireless antenna switch (physical switch) is turned on. For Vista, please click on Start-Connect to- then please select your network. If it says you are connected to the network, please click on "Open Network and Sharing Center to see if there is a red x mark between "network" and "internet". If there is none, please launch your browser (Internet Explorer) If there is, please click on that red x and see what is the message after. If it could not be identified, please contact your Internet Service Provider (ISP). If there is no problem with your ISP, please go to Start-Control Panel-Network and Internet-Internet Options-General Tab-Delete (Under Browsing History)-Delete All. After these, please try to launch your IE. You can also download the latest driver for your wireless network adapter using a different computer if the first offered solutions did not work. Please let me know if any of these works. Thank you.
