filtering, although it has nothing to do with Mac computers. (It

stands for media access control, which is a serial number that
uniquely identifies a piece of networking hardware.)

Not all routers can do this, and how you do it varies from router to
router, so check the documentation. In a typical Linksys router, for

example, you sign into the router’s administrator screen using your
web browser and then select Wireless → Wireless Network
Access. On the screen full of empty boxes, type the MAC address

of the PC that you want to be allowed to get onto the network.

Note

To find out the MAC address of a PC, press +R to open the Run dialog box. Type
cmd and press Enter. Type ipconfig/all, and press Enter. In the resulting info screen,
look for the Physical Address entry. That’s the MAC address.

Type all the MAC addresses into the boxes on the Linksys router,
click Save Settings, and you’re all done.

Place your router properly. Placing your Wi-Fi router centrally in

the house minimizes the “leaking” of the signal into the
surrounding neighborhood.

Family Features (Parental Controls)

Many parents reasonably worry about the volatile mixture of

kids+computers. They worry about kids spending too much time in front of
the PC, rotting their brains instead of going outside to play stickball in the
street like we did when we were their age, getting fresh air and sunshine.

They worry that kids are playing disgusting, violent video games. They
worry that kids are using programs they really shouldn’t be using,
corrupting themselves with apps like PowerPoint and Quicken. (That’s a

joke.)
