I have three devices (MacBook Pro, iPad and iPhone) that sometimes connects to my neighbors wifi even though System Preferences > Network says I am connected to my SSID.

If I go to the router admin page (192.168.1.254), I do not see my U-Verse admin page but my neighbors DSL router admin page. Turning Wifi On/Off usually resolves the problem sometimes.

I have even changed my SSID.

How is this possible?

Update:
The problem turns out the culprit was my roommate was using a Netgear power line adapter and so was my next door neighbor and encryption wasn't enabled on any adaptors. So whenever a device requested an IP address, it found the first DHCP to respond and connected to that network.

I can't speak for your iPad or iPhone, as I use neither, but on the Mac, go to:
System Preferences > Network > AirPort > Advanced > AirPort​
and remove the network from your Preferred Networks list. Also, your neighbor should protect their network with a password, so others can't connect to it.

I only have my own Network in that list.
