How To Connect A Landline Phone to a Modem

Before you start setting up the landline phone connection to the modem, you need to gather your equipment.

Things You Will Need to Connect a Landline Phone to a Modem

  • Modem
  • Ethernet cable
  • DSL cable for modem-to-wall connections

If you have bought the connection from your internet supplier, they probably provided you with a single box with both router and modem. Instructions differ based on which kind of equipment has been provided:

1. Cable Modem/Gateway

Step 1: Determine whether the cable modem has a specialized VoIP port, or you may find one with the label of ‘Line’ or 'Phone.' Check to see if you're using a traditional cable modem or a modem-router gateway.

Step 2: Make sure the phone isn't plugged into the power supply, then use the RJ11 cable to connect it to the phone port of the modem or gateway device.

Step 3: If you're using a gateway device, plug the ethernet cables into the LAN port of the device and connect it to the modem and PC.

Step 4: Once all of your connections are in place, you can use your landline phone.

2. DSL Modem

If you're using DSL connections, you must know that it uses phone wiring for internet connection. Moreover, it works better with the landline phone.

Step 1: You need a splitter for it. Connect it to the wall socket for a DSL connection.

Step 2: Connect an RJ11 cable to the splitter and the other end to the DSL Modem's back panel.

Step 3: Connect the other end of another RJ11 cable to the landline telephone using the remaining splitter connector.

Step 4: Using an Ethernet wire, connect the DSL modem to the PC to verify that the settings are accurate.

3. Fiber Modem

A fiber modem probably comes with a GPON port if you have a fiber modem. You just need to connect the landline telephone to an RJ11 cable. Further, plug the other end into the phone port on the device.

How To Connect A Landline To A Wifi Router

Step 1 - Power Off the Router

Turn the router off. You need to do this before unplugging any wires. Otherwise, you may have difficulty differentiating the ports.

Step 2 - Connect the Ethernet Wire

On one end, connect the Ethernet wire to the ports on the router's rear. On the other end, attach it to the correct port in the cable modem.

Step 3 - Connect Router to PC

First, connect a second Ethernet cable to the LAN port on the back of your router. Subsequently, connect the other end of the wire to your computer's Ethernet port.

Step 4 - Connect Phone to Router

Get another analog phone cable and connect the phone with the router. The phone adapter port is usually labeled 'Phone 1', located on the back of the device. This step is to maintain the connection between your landline and your wifi.

Step 5 - Turn On Modem, PC, and Router

Once you have successfully connected the router and landline, you can now turn on both modem and the PC. Once the indicator lights stop blinking, it simply means that the connection is now stable.

Step 6 - Make a Test Call

You can plug the router onto an outlet once the modem has a stable connection. Wait for the router to get stable after turning it on (the lights will stop blinking).

You can now test the first landline call.

Troubleshooting Your Internet Landline Connection

There are a few common problems you may encounter when setting up your internet landline. These include:

**1. Modem Doesn't Have A Phone Jack

**

If the modem doesn't have a phone jack, you might not be able to connect it to the landline for the internet. Here’s what we found out to help:

  1. Your ISP can assist you. You will need to have your new cable modem added to your account as your Internet modem, and your old modem disabled for Internet use but left as your phone modem.
  2. You will need a two-way coax splitter. Both Coax cable are necessary after an even split in length.

**2. Router Doesn’t Have Phone Port.

**

A phone port is necessary as you need to establish a connection through a landline.

Note: You may get wifi without a phone jack, though, because internet service does not require a phone connection. Most cable companies offer internet access by connecting a coaxial cable line to a cable modem, which can convert cable signals to Ethernet signals.

If you own a D-Link router, the best option is ATA, which is a small box that plugs into the router and allows normal phones to be used. You can also connect a landline with ATA.

3. VoIP Landlines Don’t Work During a Power Outage

****VOIP landlines are not often stable, and they can cause major trouble issues for you if you are trying to connect them to the internet. Here’s a solution: You can connect your phone system to a backup power source, such as an uninterruptible power supply (UPS), as a short-term solution. Ensure your Internet equipment is powered to restore connectivity. To put it simply, you need to plug your modem, router, switch, and VoIP phone into your UPS in order for them to turn on.

Things to Remember When Setting Up Internet Connection With Landline

1. Type of connection

You need to understand the type of connection you need. Moreover, know that you cannot wirelessly connect your landline phone to your wifi network. If you want to connect the two devices, you need to establish a physical connection.

Wifi routers can connect to the internet via DSL or cable. Fiber connections are growing more popular, but the high cost of infrastructure installation is slowing the transition.

2. Speed of Internet

This is a crucial factor because the quality of your landline is entirely dependent on it. If you have a high-speed internet connection, your voice will be crystal clear, and there will be no dropped calls.

Cable lines, on average, give a faster internet connection (about 30 Mbps) than DSL connections, which can achieve speeds of up to 940 Mbps. Spectrum, for example, offers 100 Mbps, 200 Mbps, 400 Mbps, and 940 Mbps network speeds. The network speed is also affected by your location, network traffic, and other factors.

3. WLAN Standards

There are numerous wifi standards available nowadays, including 802.11a, 802.11b, 802.11g, and 802.11n. They are capable of transferring data at various speeds and rates. The most sophisticated standard, 802.11n, can transport data at a speed of 940 Mbps.

If your connection has a high download speed, you may experience a slower internet connection and distorted audio quality, but your router does not meet the maximum level.

FAQs

What kind of connector is needed is used to plug a landline phone into a modem?

Whatever connector is compatible with the ISP will be used on the ISP side. This will most likely be a coaxial connector for a cable connection, whereas, for a feed from a satellite Internet dish or a DSL connection, it will most likely be RJ11.

On the other hand, most modems now employ an RJ45 port to connect to a router or a single computer through Ethernet.

Is there anything such as a ‘Landline to wifi’ Converter?

Yes, there are various Wireless Phone Jack Systems available in the market. Wireless phone jacks are an efficient choice if you're seeking a way to communicate over the phone from locations where you don't want to extend your phone line.

Does a wifi router need to be plugged into a phone line?

In order to connect to the Internet, the router needs a modem. DSL modems connect your network to the Internet via phone lines, and the router connects to the modem rather than the phone line.

What are the cons of internet phone service?

  • VoIP phones are known to be unreliable, have poor call quality, and may go down when there is network congestion, maintenance, or outages.
  • They are heavily dependent on a high-speed internet connection.
  • Your VoIP landlines may have extreme static sometimes because of the presence of other devices like the TV or computer on the same network.
  • Other devices drawing on the internet bandwidth could render the internet unavailable for your phone, leaving you unable to make calls.
  • VoIP-based phones are vulnerable to hacks and breaches, putting you in danger of data or identity theft.
