Router's power light is flashing

For starters, do as cold reboot. turn the router off, unplug it & remove the back up battery if so equiped(should be simple, if not skip it) Leave off for 2 minutes. Then turn it back on. Then do the same to your tv. Reenter the router on your tv. Good luck.

Please explain in detail.
If your router is not working then I will suggest you to reset the router and reconfigure the router.
create a new wireless network and see if that works.

You can go to Linksys and get the setup info. Or if you don't know how, write back with your router model number and I can find it for you.

Thanks

I do not have a solution to the problem. However, I am having the same problem. This morning the Actiontec GT704WG power and ethernet lights were rapidly flashing. The modem was non-functional. I could not even connect to the modem through the browser to see if I could find a problem.

The problem lasted a couple of hours. Then all of a sudden the modem started working again. I won't be able to tell if the problem recurs until I restart the modem. And if the problem does occur again, I won't be able to connect to the internet.

I can definitely help you on this, however, this would require us follow a few troubleshooting steps which cannot be dictated here. So, I would request you to initiate a chat session with me from the fixya homepage and we would carry on from there. Cheers
