How about Zhanjiang Tietong broadband?

I am also a Tietong operator. I have used it for two years, and there is basically no big problem. I just installed it for a while, but there are some problems, such as the card, and I can't get online. Later, I found that the network card was broken, and I didn't find any problems after replacing it. Watching videos online at home now won't make any difference. I installed 2 m. If possible, I suggest you install 4m.
