I'm on the second floor of 9#, and I'm calling Netcom. You can go to the Unicom business hall opposite the seven-star supermarket in the canteen to get your ID card. The dormitory has an interface, so you need to call a telecom business hall next to Huajiang subway milk tea shop. I have no idea who you are. It seems that I stopped pulling telecom in my freshman year, and Netcom is ok. It's very simple. The network cable and router are all connected.
