Hello!
Yes, it is possible to connect to your neighbor’s WiFi using a LAN cable. However, please keep in mind that this may not necessarily be legal and could be against your neighbor’s internet service provider’s terms of service.
Regarding your question about sharing the cost of the internet bill, it is best to consult with your neighbor and come up with a fair agreement that works for both of you.
In terms of the distance between your houses, a LAN cable may not be long enough to reach your neighbor’s house. A better solution would be to use a wireless bridge or an outdoor access point.
For the wireless bridge, you will need two compatible devices that are designed to work together to connect two separate networks wirelessly. One device will be installed at your neighbor’s house, and the other device will be installed at your house. These devices will communicate with each other wirelessly, allowing you to share your neighbor’s internet connection.
For the outdoor access point, you will need a device that is designed to provide wireless coverage over a large area. You can install this device on the outside of your house, facing your neighbor’s house. This will allow your neighbor to connect to your WiFi signal from their house.
As for the recommended WiFi router for your house, it depends on your specific needs and budget. Some popular brands include TP-Link, NETGEAR, and ASUS. You should choose a router that has the features you need and supports the number of devices you plan to connect to it.
I hope this helps!
