Internet fails every day and i have to unplug modem wait afew minutes and internet comes back

Try turning off you computer, then unplug power from router and cable modem. Wait 1 minute, then plug in the modem and wait for all lights to come on. Then plug in the router and wait for a minute. Then start your computer and let it connect.

Turn off your modem (unplug it from the wall or surge protector).

Once you have done this, wait for at least ten seconds, if not one full minute. (This allows the modem to reset itself)

Plug the modem back into the wall or surge protector.

The modem will begin its start-up sequence and finally it should respond with a "blinking" connectivity light.

If you have a wireless or wired router connected to your modem you must make certain that you follow the next steps, or the router may not work to provide you with an Internet connection.

1. Unplug the Modem.
2. Unplug the Router.
3. Wait for one full minute.
4. Plug the Modem back in to the wall or surge protector.
5 Wait for the modem to complete its start-up sequence.
6. Plug in the router. (if you plugged in the router the same time you plugged in your modem, start at step #1 and try again...)
7. Wait for the router to finish its start-up sequence.
8. Test the connectivity to the Internet.

If this does not work, please add some clarification as to what service provider you are using, the type of modem/brand, and if you have a router...

Unplug power and cable. Wait a few minutes. Reconnect it. There should be a reset in the back. Press it. It may take awhile to come back up. Test the connection with a CAT cable instead of wireless.

Contact Comcast it this fails.

Check the lights on your modem and make sure that it is connecting. If it is, power off the modem (unplug it normaly) and the router (same unplug). Now wait a few mins, power the modem back on first and wait for all the lights to turn green (some cable modem will have a yellow light). Now plug in the router and wait for all its lights to come on. Now try the internet again. If this fails disconnect the router from the modem (ethernet cable) and plug your computer directly into it. Restart the modem as you did before and when all the lights are on, try internet again. If you have internet at this point the problem is in the router somwere, if not call your internet service provider.

Hi. You can "powercycle" your deviced first. turn off your computers, router and modem (make sure you unplug the router and the modem from their power source), wait for 2 minutes then turn the modem on, wait for another one minute then turn the router on, wait for another minute then turn the computer/s on. :-)

There must be a small reset button on your router. Hold it down for 30 seconds. Release it. wait for one minute. Now unplug the power and plug it back in. Wait for 1 minute.
Once you reset the router, it will come back to factory default settings.
You will need to reconfigure the router form the start according to your Internet service provider.

If you go through a router unplug modem and router wait about 2 or 3 minutes plug modem back in first wait about one minute then plug router back in and then try to hook up online.

Sounds like either a cable has come unplugged/broken, the router/modem is on its way out, or your DNS cache needs to be cleared.
In this order:
Unplug the modem and/or router power cords. While unplugged, make sure the cat5 cables are connected securely(if using wired net).
Wait about 30 seconds to a minute, then plug the modem and/or router back in.

Test your internet connection.

If there still no connection to the internet, Click Ctar>Run, type in cmd, hit enter. This opens the command prompt.
On the black screen, type in ipconfig/flushdns
Close the command prompt, and re-test your internet connection.

If it still fails, verify with your ISP that your internet connection is active, and try a different router and/or modem.

First of all... Unplug the modem, unplug the Airport (WiFi router) and turn off the Airport connectivity in your MacBook.
After 5 full minutes... Plug in the modem.
Wait 2 full minutes... Plug in the Airport.
Wait 1 full minute... Turn on the Airport connectivity in your MacBook.
After all of that... 
If you're still not back up and running and you're using an Apple Airport, open the Applications folder, open Utilities, open Airport Utility.
If you're using any other type of WiFi router, use the Network Diagnostics button that should show up in the web browser window when you try to go to any website.

have you tried powercycling your modem? turn of your computer, unplug the power cord from the back of the modem. wait a minute (literaly). plug power back into modem and wait for lights to come on and stop flashing. power computer back up. Check to see if connections works. Also check your cable connections between the modem and the computer. If all fails contact your Internet Service Provider, who most likely provided you with the modem.
