How to factory reset my Linksys RE6300 AC750 Boost Wi-Fi Range Extender? without the 10 second rule reset button

The other day I have a customer that I was unable to factory reset his RE6300 AC750 Boost Wi-Fi Ranger Extender by the method of press 10 second its reset bottom, so I was kinda lost since I have no a wifi booster issue every day and even memorizing every brand, I went to the internet and was poor the searching. the only basis and that it is always repeated in all type brand is that all device has its own IP address that allows a tech to go inside and play with it. 


I fortunate have a laptop close to me and without connecting this laptop to his already router/modem (Gateway). I put an ethernet cord from laptop to the only port that this Linksys RE6300 AC750 Boost Wi-Fi Range Extender has in one side, then I went to IE and type its ip address 192.168.1.1 and the default password admin. the second step is to go to its property and click reset to default factory. the rest was easy, to make this wifi booster back to sync to my customer gateway  by pressing the WPS button in both pieces of equipment
