I am thinking of getting a ROKU EXPRESS, small box plus remote. My building provides FREE wifi internet which requires a given password for all residents to use. I currently use it for my desktop as do several other residents. No one has an issue with spotty or slow connection speed. This prompts me at ask if the ROKU will SEARCH and FIND this or any unsecured wifi to connect to? Is the ROKU a monthly fee or simply a one time purchase for the device? If subscription does the fee go up after the TRIAL period, as cable fees did? Which is why I got rid of it. I currently use my desktop to watch the same content I watched on cable. All for FREE, as in no subscription services or paid websites. Only free sites like YOUTUBE and movie, news sites for me. A friend just bought a ROKU. He is not tech savvy and does not know where the wifi is coming from. Either from the buildings wifi, his daughters cell, or somewhere else. Enlightenment please.
