If you want to boost the signal of Wi-Fi then you need a Range Extender. There are a lot of companies who deal with the Router, modem, and extender but I think Linksys is the best brand in the field of extenders. These extenders are easy to set up and if users get any kind of problem in connecting with the extender then reset the router to make the all settings default.
Here are the steps which help users to reset the router.
There are two different ways to reset the router to the factory default. The first one is that the user will get the reset button on the front or backside of the router. Press the reset button and hold it for 20 seconds. Now remove the power adapter of the extender and then plug it back. Now fill all details of the configuration.
The second way is that the user can reset the router by using the webpage extender.linksys.com. Open the webpage and log in by using the default credentials. Now click on the Administration and then choose a factory default option. After that click on the “restore factory default” option and then turn off the extender for 30 seconds and then turn it on.
