So here is what I do when I'm staying at my rented house near my college. I took a fiber connection from the ISP. But a friend of mine lives nearby he uses his landlords WiFi from the same ISP. From him I got the WiFi pass. And I discovered that that WiFi router uses admin1 as it's admin password. So I got the ppoe username and password from it. The next month I didn't paid the ISP bill so they suspended my internet connection. And put that ppoe username and password on my router. The ISP was calling me for two months to pay the bill but I didn't. And somehow they stopped calling and I still have the fiber connection. It's been over a year now and in still using it.
