What the TP-Link RE315 Is

The TP-Link RE315 is a dual-band AC1200 WiFi range extender that plugs directly into a wall outlet. It rebroadcasts your existing WiFi to reach dead zones in your home or office. It delivers up to 867 Mbps on the 5 GHz band and up to 300 Mbps on the 2.4 GHz band, covers roughly 1,500 square feet of added range, and supports around 25 to 30 connected devices depending on your traffic.

The RE315 is OneMesh and EasyMesh compatible, so when it is paired with a supported TP-Link router it can share a single WiFi name with your main network for seamless roaming. It also includes a Fast Ethernet port for connecting a wired device such as a smart TV, streaming box, or game console.

What Is in the Box

  • TP-Link RE315 WiFi range extender
  • Quick Installation Guide

No Ethernet cable or power adapter is included. The unit plugs directly into a standard wall outlet, and you only need an Ethernet cable if you plan to use the wired port or Access Point mode.

How to Set Up the TP-Link RE315

There are three setup methods. The Tether app is the easiest for most people, the web browser method gives you the most control, and the WPS button is the fastest if your router has a WPS button. Choose one. You do not need all three.

Before you start: Plug the extender into an outlet near your main router and wait until the Power LED is solid on. Keep your router's WiFi name and password handy.

Method 1: Set Up With the TP-Link Tether App (Recommended)

  1. Download the free TP-Link Tether app from the App Store or Google Play.
  2. Open the app and sign in with your TP-Link ID, or create one if you do not have it.
  3. Tap the plus icon, choose Range Extender, and select the RE315 from the list.
  4. Follow the on-screen steps. The app will have you connect your phone to the extender's default network, then pick your main router's network and enter its WiFi password.
  5. Create a local admin password for the extender when prompted, then finish setup.

Method 2: Set Up With a Web Browser

  1. On a phone or computer, open WiFi settings and connect to the network named TP-Link_Extender.
  2. Open a web browser and go to http://tplinkrepeater.net (or http://192.168.0.254).
  3. Create an admin password to log in. This password protects the extender's settings.
  4. Select your router's 2.4 GHz network name and enter its WiFi password. This is your router's password, not the admin password you just created.
  5. Select your router's 5 GHz network name and enter its WiFi password.
  6. Confirm or customize the names of the extended networks, then finish. The extender will apply settings and reconnect.

Method 3: Set Up With the WPS Button

  1. Press the WPS button on your main router.
  2. Within two minutes, press the WPS button on the RE315 for about one second. The signal light will start blinking.
  3. Wait for the signal light (and the 2.4 GHz and 5 GHz lights) to turn solid white, which confirms a successful connection.
  4. If your router is dual-band and only one band connects, repeat the steps to connect the second band.

Note: WPS is not supported on iOS devices for triggering the connection, but the button method works fine when both the router and the extender have WPS buttons.

Find the Best Location After Setup

Once connected, unplug the extender and move it about halfway between your router and the dead zone. It must stay within range of your router. Wait about two minutes for the signal light to settle.

  • Solid white signal light: Good location. Leave it here.
  • Solid red signal light: Too far from the router. Move it closer until the light turns white.

Keep the extender away from microwaves, cordless phones, baby monitors, and Bluetooth devices to reduce interference.

Understanding the LED Lights

LED Status Meaning
Power Solid on Extender has power and is ready
Power Off No power. Check the outlet
Signal Solid white Connected with a good signal and good placement
Signal Solid red Connected but signal is weak. Move closer to the router
Signal Blinking Connecting, usually during WPS pairing
Signal Off Not connected to the router
2.4 GHz / 5 GHz Solid white That band is connected to your router
2.4 GHz / 5 GHz Off That band is not connected

How to Access the IP Admin Settings

You can reach the RE315 management page at any time to change settings.

  1. Connect your device to the extender's WiFi network or to the same router the extender is connected to.
  2. Open a web browser and enter http://tplinkrepeater.net.
  3. If that address does not open, enter the IP address http://192.168.0.254 instead.
  4. Log in with the admin password you created during setup.

Cannot find the page? If the extender is already connected to your router, its IP may have changed. Open your router's DHCP client list to find the extender's current IP address, then enter that address in your browser. As a last resort, reset the extender (see below) and use 192.168.0.254.

How to Change the WiFi Name (SSID)

  1. Log in to http://tplinkrepeater.net with your admin password.
  2. Go to Settings > Wireless > Extended Network.
  3. Enter a new name in the 2.4 GHz SSID field, the 5 GHz SSID field, or both.
  4. Click Save. Devices will need to reconnect to the renamed network.

If you would rather have the extender copy your router's network name exactly, enable the option to use the same SSID as the host network. This is helpful for seamless roaming, especially on OneMesh setups.

How to Change the WiFi Password

There are two different passwords on the RE315. The extended network password is what devices use to join the extender's WiFi. The admin password is what you use to log in to the settings page. Change the right one for your goal.

Change the Extended Network Password

  1. Log in to http://tplinkrepeater.net.
  2. Go to Settings > Wireless > Extended Network.
  3. Enter a new password for the 2.4 GHz and 5 GHz networks.
  4. Click Save and reconnect your devices with the new password.

Note: By default, the extended network uses the same password as your main router. If you want them to match, leave it set to copy the host network.

Change the Admin (Login) Password

  1. Log in to http://tplinkrepeater.net.
  2. Go to Settings > System Tools > Admin Account.
  3. Enter your current password, then your new password.
  4. Click Save.

How to Set Up Access Point (Bridge) Mode

The RE315 does not have a setting literally labeled "bridge mode." Its default Range Extender mode already acts as a wireless bridge that repeats your existing WiFi. If instead you have a wired internet connection (an Ethernet wall jack or a wired router) and you want to turn it into WiFi, use Access Point mode. This is the RE315 equivalent of bridge mode.

  1. Connect the RE315 to your wired router or Ethernet wall jack using an Ethernet cable plugged into the extender's Ethernet port.
  2. Log in to http://tplinkrepeater.net with your admin password.
  3. Click the Mode menu (top of the page) and select Access Point.
  4. The extender will switch modes and restart. Follow the prompts to name the new WiFi network and set its password.
  5. Reconnect your devices to the new Access Point network.

To return to extending a wireless signal, switch the Mode setting back to Range Extender.

How to Update the Firmware

Keeping firmware current improves security and stability.

  1. Log in to http://tplinkrepeater.net.
  2. Go to Settings > System Tools > Firmware Upgrade.
  3. If an update is available online, follow the prompts to install it. You can also update through the Tether app.
  4. Do not unplug the extender during the update. It will restart when finished.

How to Reset the RE315 to Factory Defaults

A reset erases all settings and returns the extender to its out-of-the-box state. Use this if you cannot log in, you forgot the admin password, or setup is stuck.

  1. With the extender plugged in and powered on, find the Reset button.
  2. Use a pin or paperclip to press and hold the Reset button until the LEDs blink, then release.
  3. Wait for the extender to restart. It will return to the default network name TP-Link_Extender and the default address 192.168.0.254.
  4. Run setup again using any of the three methods above.

Troubleshooting Common Issues

tplinkrepeater.net Will Not Open

  • Make sure you are connected to the extender's WiFi (TP-Link_Extender if it is unconfigured).
  • Type the address with no www and no extra spaces, or use http://192.168.0.254.
  • Turn off mobile data on your phone so it does not bypass the local connection.
  • Try a different browser, or open a private or incognito window.
  • If the extender is already on your router, check the router's DHCP client list for its current IP and use that address.

Signal Light Is Red

  • The extender is too far from the router. Move it closer to a halfway point until the light turns white.
  • Remove sources of interference such as microwaves and cordless phones.
  • Adjust the antennas to an upright position.

Extender Connects but Internet Is Slow

  • Move the extender closer to the router. A weak link to the router limits the speed it can pass along.
  • Connect performance-heavy devices to the 5 GHz network for faster speeds at shorter range.
  • Confirm your devices are joining the extended network and not the weaker original signal.
  • Update the firmware, then restart the extender.

WPS Setup Fails

  • Press the router's WPS button first, then the extender's WPS button within two minutes.
  • Some ISP gateways disable WPS by default. If so, use the Tether app or web browser method instead.
  • Move the extender within a few feet of the router during pairing, then relocate it afterward.

Devices Will Not Connect to the Extended Network

  • Confirm you are using the correct password. By default it matches your main router's password.
  • Forget the network on your device, then rejoin it.
  • Restart the extender by unplugging it for ten seconds.

Forgot the Admin Password

  • There is no recovery option. Reset the extender to factory defaults, then create a new admin password during setup.

Access Point Mode Has No Internet

  • Confirm the Ethernet cable is firmly seated at both ends and the cable itself is good.
  • If you are using an in-wall Ethernet run, test the extender plugged directly into the router first to rule out the wall wiring.
  • Confirm the unit is set to Access Point mode under the Mode menu.

Frequently Asked Questions

What is the default login for the TP-Link RE315?

The RE315 has no preset password. You connect to it at http://tplinkrepeater.net or http://192.168.0.254 and create your own admin password the first time you log in.

What is the IP address of the RE315?

The default IP address is 192.168.0.254. If the extender is already connected to your router, its IP may differ, so check your router's DHCP client list to find the current address.

Does the RE315 create a separate WiFi network?

By default it can broadcast its own extended network name. You can also set it to use the same name as your router, which is recommended on OneMesh or EasyMesh setups so devices roam without switching networks manually.

Can the RE315 work as an access point?

Yes. Connect it to a wired router or Ethernet jack with a cable, then switch it to Access Point mode in the Mode menu. This turns a wired connection into a WiFi network and is the RE315 equivalent of bridge mode.

How far can the RE315 extend my WiFi?

It adds roughly 1,500 square feet of coverage and supports about 25 to 30 devices. Real-world range depends on walls, interference, and how strong the signal is where you plug it in.

How do I reset the RE315 if I forgot my password?

Press and hold the Reset button with a pin until the LEDs blink, then release. The extender returns to factory defaults so you can set a new admin password during setup.
