lemme cut to the chase, I need to piggyback off my neighbors wifi without a password. I am currently working in graphic design and my roommate has some random software on our wifi network that cuts signal at night. This is quite troublesome to me as I am very productive at night and this is very very annoying. Lately I have been using my phones hotspot but this is simply not realistic in the long run as it costs me quite a lot of money. I have tried negotiating and he is very firm on not changing this system.

What can I do without using his computer to disable the software or piggybacking on another signal? I can provide any details needed by the way!
