That's very kind of you. Our neighbor has an open WiFi that my family uses when our WiFi is misbehaving. I wish I could give something back, but I don't even know which neighbor it is.
Well he's a bit older and struggling with money as it is, i actually got him a directional antenna and installed a omnidirectional one in my house for him to get a good reception.. Hes mostly playing on-line games and checking his email and the stock market.
Some time ago I made a second SSID on my wireless router and gave it this standard name: https://openwireless.org/
Unfortunately, I've never noticed anyone using it. Anecdotally, however, take this as one data point that I've never had a problem with bandwidth hogs.
It sure comes in handy when guests come over---there's no password to explain.
