If you have a NetGear extender red light is blinking, you may have hit a problem. And here is what you can do to solve this problem. Make sure your extender is not too close to the router. Move the extender to a spot where it can best cover the whole house. The extender needs to be in a vertical position upright. Don’t place the extender in a way where it is lying down. You should restart the extender by unplugging it and then wait for 10 seconds and plug it back in. If the extender is still not working, you should contact the support team of Netgear at Mywifiext.net.
