My home network has 2 desktop Macs connected by ethernet and I use Airport Express to connect 2 MacBooks with WiFi. My MacBook works fine. But when my daughter comes home from college the network immediately begins shutting down. I have to restart our cable modem to restore the network to all the machines. I think the network interruption is associated with my daughter's MacBook going to sleep or waking up, but I'm not sure about that.
Does anyone know what is going on and what to do about it?
