To set up a Wi-Fi environment in a detached house, there are three main options: fiber-optic internet, a home router, and mobile Wi-Fi. This guide explains the features of each option, the installation steps, and the procedures required when moving house.

What types of internet connections can be used in a detached house?

Fiber-optic internet

This is the fastest type of connection and uses optical fiber. It requires installation work to activate, but its biggest advantage is that it can provide stable connectivity for multiple devices at the same time. With the spread of smart home appliances, fiber-optic internet is the most recommended option for detached houses.

Home router

This is a "plug-in-and-use" Wi-Fi solution that works simply by connecting it to a power outlet. It does not require installation work and is easy to set up, but its communication speed may be lower than fiber-optic internet.

Mobile Wi-Fi

This is a portable communication device. It can also be used while away from home, but there are limits on the number of simultaneous connections and on connection stability. It is better suited to people living alone.

Why is fiber-optic internet the best option for a detached house?

  • Speeds are less likely to drop even when the whole family is online at the same time
  • Flat-rate plans with unlimited data usage are common
  • Unlike apartment buildings, the line is not shared with other households, helping maintain high speeds
  • It can support a growing number of IoT home appliances

What is the process for Wi-Fi procedures when moving?

  1. Check whether the new address is within the service area
  2. If the property is rented, obtain permission from the management company or landlord for installation work
  3. Complete the relocation procedure with the line provider and internet service provider
  4. Remove the current line
  5. Carry out activation work at the new home (attendance required for about 2 hours)

Frequently Asked Questions (FAQ)

Q. How much does fiber-optic installation cost?

It is generally around 20,000 to 40,000 yen, but in many cases promotions make the effective cost free. Check each provider's campaign details in advance.

Q. Can fiber-optic internet be installed in a rented detached house?

Permission from the management company or landlord is required. Because the line is typically brought in through an opening in the exterior wall, confirm this in advance before signing a contract.

Q. What should I do if the connection is unstable?

Effective measures include restarting the Wi-Fi router, changing its location, introducing mesh Wi-Fi, and installing two wireless LAN routers in bridge mode.
