The Linksys extender Login process is easy to do, but what if you encounter the issue only during the setup procedure? Or it might be possible that it isn't working now. Or you are having an intermittent connection. Just looks as if the extender is not having the old software. If you are trying to install the range extender you have trouble doing it with setup software. Sometimes the range extender does not blink the LEDs. So, if doing the Linksys WiFi extender with the proper guide you face the same condition then, create a backup of your extender device. Configure and restore to avoid the configuration process. Just tap on Management on the backup configuration and click gently on the save settings on the Linksys device setup.
