I would have Ethernet cat 5e or 6 runs laid and supplement with Wifi as it will be unlikely to get good whole house coverage with Wifi routers. Wifi Throughput drops as devices are added and/ or the distance from the Wifi router increases.

In addition, there are potential security risks depending on the wireless security used.

Thanks David. I do have concerns with the wifi, since there will be office in basement, and computers/tablets thru out the rest of the house. Looks like time to research better wifi options...... 2 routers? Supplemental signal booster?

thanks for this info, nice post
