Is Beijing Founder Broadband easy to use?

Never use Founder Broadband, especially regretting making such an absurd decision. This network experience is extremely poor, and the first month is not bad (I run 50M/ year). Then it broke down in three days, fell off in two days, and fell off during the evening rush hour. When the engineer came to repair it, he said that my router was faulty (the router was theirs), and I replaced it with a new one. He also said that I was a router (NND). Key point: a large group of people came in without shoes, and I managed to clean the floor! Finally, attach a frame-dropping rhythm diagram.
