Not sure I can help you author. But if the pisowifi you're talking about is the one i have in mind, the device used by most computer shop owners nowadays to connect connect to wifi but you have to drop coins in the said device, basically that's how it works, if I were you I'd better ask the person who installed that about this because they supposed to know this area better than anyone else and most importantly less post technical issues if they do it rather than you do it yourself.
