Watch video :

The network security key is essentially a password that was setup to control access to your network. Presumably, when you set it up you gave it a password that you could remember, but not so obvious that people could easily guess. If you've forgotten or lost the password, you can reset the router by using a paperclip and holding the reset button for about 10-15 seconds. Once you reset the router, it will be restored to its original factory defaults and you can then setup again your wireless networking.

There is a reset button on the back of your router, hold this down for 30 seconds with a pen. You will need to go through the whole setup process after this.

connect to your router with a network cable and regenerate a new network key under wireless setup.

You dont need a wireless key to connect over a cable

You will need to check the wireless settings of the router .
Is there any computer connected to the router with the Ethernet cable?
If not then connect 1 computer to the router and open the router set up page. Once you open the router set up page, you will be able to find the wireless network key.
Use that password to connect to the wireless network

Reset Password.

Hope this idea helps you.

Thank you for using fixya.

I know exactly what has happened
u did not knew the password for router manager
u reset it
After reset router , it came back to its factory defaults, now the password will come back to its factory defaults ( if u still dont know the factory defaults password, check manual provided to u with this router )
After reseting , as router came back to factory defaults , it also changed the wireless encryption key or WPA password with which u were able to connect earlier to its factory defaults original key and due to that reason u are getting limited or no connectivity coz the WEP or WPA key has changed.
Solution: IF U know the original wireless key or WPA key try to reenter it and see whether it connects or not
if still does not work

Then connect ur PC or laptop with ethernet or LAN CABLE (CAT)
Your internet will start working with the cable
NOW u will be able to open the router manager page
Type the factory defaults password and log in
Then goto the wireless settings page and check what is the WEP key stored in ur router and also try to channels of the router and see wherher it increases the signal strength or not
Once you have got the key from the router manager page
Try to reenter it and then surely it will work.........
Best of luck
