Generally speaking, Tianyi Fiber Cat has four ports, the port 1 is Gigabit, which is closed by default, and the ports 3 and 4 are 100 megabytes, which are open. Now your Gigabit port can be used, which means that the master of Telecom has activated the 1 port for you, but your 34 port can't be used. The host should have closed ports 3 and 4 or changed them to other uses, such as IPTV. You can use Gigabit ports, why use 100M ports? The way to change it is to continue to call 10000 and ask the master to open ports 3 and 4 for you, or Baidu to find out how to activate the telecom fiber cat port (more troublesome). But telecom maintenance masters are usually busy. Besides, it's not impossible to get online. Can you invite them over? Everything will come naturally.
