Re: Computer game room
Set it up so your kids' computers and game consoles can connect to each other and the Internet with CAT5e or CAT6 wiring. Place a few network jacks in convenient locations to connect laptops or their friend's computers when they have a LAN party. This should all connect to your Internet router with wires.
Don't depend on wifi (wireless networking). It can be flaky at the worst possible times; wired connections will give them a better interactive gaming experience. Here's a thread I started a while back on the pitfalls of wireless networks: https://advice.thisoldhouse.com/showthread.php?t=108106
Of course, you probably will want to have a wireless network for convenience, and for connecting your assorted handheld devices to the Internet. Just be aware of the potential issues and what you can do to minimize problems with the wifi.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
