Hi

This often happens with Routers and modems after a power cut.

Turn the router of and on again or press the reset button at he rear (some reset buttons are pressplates that you need a pen tip to press and hold for a few seconds).

After this, the router should reset itself and your internet access should be restored.

I hope this helps.

Which model of router are you using?

First, to reset the router to factory default setting, press and hold the reset button for few seconds (It is at the back of the router near the DC Power Jack). The LEDs will then blink and the routers factory settings wouls be restored.


Please note that after RESETTING THE ROUTER to defaults, ALL SETTINGS WILL BE LOST AND YOU HAVE TO RECONFIGURE IT. Generally, after hard reset you get the connectivity, however, you have to make the connection secure etc.
Please, refer the product guide/manual and make configurations as per the details provided by your Internet Service Provider (ISP).


GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

You may have a bad power supply.
You would be better off picking up a small APC or UPS and have all your computer devices running thru.
It is common that after a power interruption the modem must reset to regain it lost signal

If the firmware update was interrupted, the router may be "bricked", meaning it has corrupted files and will not be able to function as it should. You should call NetGear support and see what they suggest, since you probably won't have the tools necessary to restore the firmware.

Try to configure your network options and properties if it doesn't work,reformat your system.This will refresh and cure the problem.

Hold down the reset button for 30 seconds to restore the default settings, it removes all security and the wep key.

Try to reset the router to his default configuration by pressing the reset bottom of the router for 15 second. try to connect using the router connection
