It must be that the telecommunications speed is fast. I installed the bandwidth of the telecom, 4 m, and the speed measurement could reach 570 k/s at that time. Now the telecom says that it will be upgraded to 6M for free, and the speed measurement with 360 can reach about 630 k/s, and the network speed is still quite powerful. The network speed of Netcom (now even Unicom) is really not as fast as that of Telecom. My mother-in-law's family belongs to 2M Netcom. That's too fast, I can't even afford to lose my life! ! I have used Netcom in other places, and I feel that it is not as fast as telecom!
