Here Are Some Things To Consider Before You Connect Your Landline Phone To Your WiFi router

Be sure to take into account these important aspects before you connect your landline phone to your router. They will affect the speed at which the phone connects to the internet.

Connection type

You cannot connect your landline phone to your Wi-Fi router wirelessly. You will need to make a physical connection between the two devices.

Wi-Fi routers are able to connect to the internet using either a DSL connection (such as AT&T’s DSL network), or a cable connection like Cox. Although fiber connections are increasingly popular, as the infrastructure is quite expensive, the transition to them is slow.

All these services provide Voice over IP (VOIP), landline phone service.

Internet speed

This is an important consideration as it directly affects your landline quality. High-speed internet connections will ensure that you can hear clearly and have no dropped calls. Cable connections generally offer a faster internet speed (30 Mbps) than DSL connections (which can reach up 940 Mbps). Spectrum offers speeds up to 100 Mbps, 200Mbps, 400Mbps and 940Mbps. Your location and network traffic are also factors that affect network speeds.

Wi-Fi standards

There are many Wi-Fi standards, such as 802.11a and 802.11b, and 802.11g. You can transfer data at different rates and speeds. The fastest standard, 802.11n, can transfer data at speeds of up to 940Mbps. You may experience a slow internet connection or distorted voice quality if your router has the lowest standard but a fast download speed.
