No connectivty to internet

Limited connectivity
If you get a 'Limited connectivity" on you wireless connection on your laptop, it means that the wireless card on your laptop probably 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 then click Repair.
This will force the wireless router to issue a IP address to the wireless card on the laptop.
Also try resetting the wireless router by turning off the power to the wireless router for a few minutes and the boot up your computers.

You just have to restart the router it self. i mean take out the power adapter and plug it back. No need to press the reset button as it may put back the router to factory default.

These kind of issues are common. The DHCP service (which gives IP to your computer and wireless device) hangs up some times on most routers.

Let me know if you still face the problem after power cycling the router.

Well, actually... it might help to turn the router off and then on again. Sometimes power-cycling the router can reset it, which might need to be done. I'm a big fan of the power-cycle; it works for all sorts of obscure problems.

Once the router is on again, use the laptop and adapter to check for wireless networks. If you still can't find a network, disconnect the ethernet cable from the back of the desktop computer, and try the wireless adapter with the desktop PC. If it works, the problem is with the laptop (possibly a power supply problem). If it doesn't work, the problem is either the adapter or the router.

Ideally you should then try your adapter with a friend's router. Eventually you will discover whether the router is playing up or whether the adapter is faulty.

In my (admittedly still limited) experience, connection problems are rarely about faulty equipment and more usually about incorrect settings, so it might also be worth running the New Connection Wizard from Network Connections in the Control Panel.

Good luck!

It seems to be that either wireless connectivty is breaking up or Wireless modem is Power off and on again and again. So, please check power connectivity first. if everything is right, simply call ISP. They will fix it at their end.

Hi i'm Rain.
Limited or no connectivty means that your router is not picking up the connection or it is connecting but may have something blocking the connection.
To repair this you will need to reinstall the routers drivers to your computer. You should have a disk that came with the router. Use the disk to reinstall the needed drivers to connect to the internet.
If you do not have the disk , the easiest way is to call whom ever you got the router from and have them bring the disk out or go pick the disk up. Always remember when you have a router installed by a company the disk belongs to you. Most times the technician will not give you the disk because that way you will have to call them to come out to reinstall it. Thats more money outta your pocket.

Try turning everything off- pc, modem, router, other pcs and periferals on the network, wait 10 minutes, then start turning everything on gradually- pc, modem router, etc. Hopefully everything will reset ok.

Check if it's recognised on the local area network etc,make sure driver is installed and you may need to reset all pc,router etc to get connection.Now remember you need a router for this to work,with only a modem it will not function.You also need to restart all instruments etc before it's picked up by the router and the network..Google a bit and it will solve this.Make sure it uses wifi and not bluetooth as then it will need the right bluetooth connection to your pc..

Run a cat5 cable from the laptop to a cat5 port on the router, open internet explorer in the address window type http://192.168.1.1 or what ever the IP address of the router once you have accessed the router create your PPPOE internet connection, enter your Internet Service Provider's username and password. Once you have done this, disconnect the cat5 cable and connect wirelessly to the router from the laptop. If all this fails press and hold the reset button on the back of the router for 10-15 seconds this will reset the router to factory defaults. connect to the wireless router and create the PPPOE connection.
