aem, different ISP have different policy about who/what can access their network. It's their right to lock MAC address to certain customer ID. If the ISP locked to his router's MAC address, his laptop won't work at all, because the MAC address is unrecognized, thus blocked from entering layer 3 negotiation (IP sub stack).
I personally won't suggest a modem reset. A cable modem is a whole different beast compared to a DSL modem. It got specific ISP settings in it that will spell TROUBLE if you play with it. On the other hand, if it's a DSL modem, I wouldn't hesitate to suggest a reset, because there' s really nothing to worry about in it.
