When we watch a DVD on our home entertainment system, we can’t get on the Internet with our MacBook Pros. The network quits. When I turn off the DVD player, the network is again accessible by the computers. I can’t swear to it, but I think this is just a recent problem. For what it’s worth, we have an aging Airport Extreme that sits immediately next to the DVD player. Any ideas on what’s going on?
