Phone keeps connecting to neighbours xfinity hotspot, how do i get it to connect to mine

I have an iphone 7 and an iphone 5 and everytime i try to connect to my hotspot in my house from my iphone 7, it connects to my neighbours. But my iphone 5 connects perfectly to mine. My iphone 5 has 3 bars and is fast wen usinf the hotspot but my iphone 7 has 1 bar and is slow so how do i get my iphone 7 to connect to the Wi-Fi hotspot in my house rather than neighbours. I know the way xfinity sets up their hotspots is stupid because they keep the same ssid for every router lol so you don't know which is which. But i know for a fact that my iphone 7 is connected to neighbours and is not recognizing my own. I've also tried forgetting the network and resetting network so i don't know. Might have something to do with ip address or something

Going from memory; my instructions may not be perfect. But it should be the same as it was on my old iPad:

In "Settings", select "Wi-Fi". Hit the "information" (letter i, in a circle) for your neighbor's network. You should have a button marked "Forget this network". Hit that.

Then, connect to your private network (preferred) or the Xfinity network that your router generates.

What do you mean by "xfinity hotspot"?

I'm not with Xfinity myself, but as I understand their service, their routers provide two Wi-Fi networks. One is labelled something like XfinityWiFi, and the other will have a totally different name.

The XfinityWiFi hotspot is a service that Xfinity provides for its users to allow them to connect to any of thousands of XfinityWiFi hotspots around the country. This allows their customers to get Wi-Fi access when they are away from home. Normally there's no way to select a specific hotspot when your device is within range of one of these hotspots. The hotspot provides access only to the Internet and can't be used for local networking.

In your own home, you should always be using the other network provided by the router. This has much better security, bandwidth and allows you to network with other devices attached to the router. This is network is not normally referred to as a hotspot, but as your private Wi-Fi network.

Your question brings up a number of other points:

1) If you can connect to your neighbours hotspot, then either coincidentally both are using the same encryption pass phrase, or more likely, the network has no encryption security at all. This is normally what XfinityWiFi hotspots would offer as you need a username and password to complete the connection to the Internet once you have connected to the hotspot.

2) Are you using Windows 10? It is some time since I last ploughed through Windows 10 settings, but I vaguely remember that Microsoft stupidly defaulted devices to connect automatically to Wi-Fi networks with no encryption.

3) If your neighbour has an encrypted network, and it is using a different pass phrase from your own router's offerings, why is your device using your neighbours pass phrase?

4) Some devices simply are not Wi-Fi compatible with certain routers. If your iPhone 7 is incompatible with your router, it might not be possible to connect to your router by Wi-Fi, and it is taking the alternative.

5) Finally, how do you know you are connecting to your neighbours router? Signal strength is no indication. Your iPhone 7 may simply be deaf.

That isn't your nabor's hotspot, that is actually a public international or nationally as far as I know, hotspot Try blocking it.

Your Wi-Fi settings in your PC will have an "order" in which to connect to. Disable the "connect automatically" if there's such an option, and move the Wi-Fi down the list. Your Wi-Fi will connect in priority of the list, from top to bottom, for the first signal available.

You can chose you Wi-Fi in settings, just pick your Wi-Fi not his and chose don't not automaticly connecf

Hen either coincidentally both are using the same encryption
