According to your description, if you don't have a broadband port, you can share a port with your neighbors who do, but you need to buy a switch. The function of the switch is to increase ports without affecting the network speed.
If you want to install wireless broadband, I suggest you log in to the online business hall of Anhui Telecom to handle wireless broadband business, and recommend smart home broadband package. Smart home package 159 includes 4M high-speed broadband, which can be used to send mobile phones and phone bills. Free use of iTV (recommended package) 20 14 1.05-3.05. Users who successfully place an order (broadband order) in the online lobby can get a lucky draw opportunity, and a lucky draw prompt box will pop up on the page. Total package price: ¥ 159 yuan/month.
You can log on to Anhui Telecom's online business hall for a more detailed understanding.
I hope my answer is helpful to you, and I hope you can adopt it.
