I think, but I am not sure, I mentioned that we received a hand-me-down Mac for Christmas. At first, the internet wasn’t working. We restarted it and everything but to no avail. Luckily, there was really no issue at all that we had to worry about, for when we went to Minnesota for two weeks, we unplugged our modem (and all our other electronics). Since then, our internet has been working like a charm.
