Windows 10: how did the technician fix my internet

i have a router in the living room at home. i extended a long network wire to my bedroom and i connected that wire to a second router in my bedroom

a couple of hours ago the internet in the living room and my bedroom spoilt. the exclamation mark in a triangle appeared next to the wifi icon and it said can't connect to internet. it was like that in all the laptops in my house. i switched off the router in the living room and i switched it back on. that fixed the internet in the living room but the internet in my bedroom stayed spoilt. i couldn't get the internet in my bedroom to work. i switched my router off and on many times and the internet in my bedroom would not come back

i connected the laptop to the long network wire which comes into my bedroom. the internet worked. i connected the long internet wire to the router in my bedroom and then i connected another network wire from that router to the laptop. there was no internet and the exclamation mark in a triangle appeared next to the wifi icon. i gave up and i called a technician to come to my house

first the technician connected the long network wire which comes into my bedroom to the laptop and then he went to cmd and he typed a bunch of ipconfig commands. after that he connected the long network wire to the router in my bedroom and he connected network wire from router to the laptop and he typed more commands in the cmd and then the internet was fixed in my bedroom

can anyone please tell me exactly how did the technician fix the internet in my bedroom and what were the commands that he typed in the cmd when the long internet wire was connected to the laptop and when the network wire from the router was connected to the laptop?
