Every week a Guardian Money reader submits a question, and it’s up to you to help him or her out – a selection of the best answers will appear in next Saturday’s paper.

This week’s question:

We are about to give our friendly neighbours access to our wifi – they can’t get their own – but wonder if there are reasons why we shouldn’t? Will we both be able to watch Netflix at the some time? If they access dodgy sites, will it come back on us? Does anyone do this?
