How to Connect a TP-Link Extender to a New WiFi Network

Check the extender model and new router

Find the model number on the extender label and make sure the new router's WiFi is active. The steps below fit common TP-Link range extenders, but button labels and app screens can differ by hardware revision.

Connect with the WPS buttons

Place the extender near the router. Press WPS on the router, then press the extender's WPS or RE button within the interval specified in its manual. Wait for the wireless indicator to show a successful link before unplugging it.

How to connect a TP-Link AC750 WiFi range extender

For an AC750 model such as the TP-Link RE220, use WPS if the router supports it, or set up through the TP-Link Tether app. Select the router's current network and enter its WiFi password; the AC750 label describes the extender class, not a guaranteed internet speed.

How to connect a TP-Link 300Mbps WiFi range extender

A 300Mbps-labelled TP-Link extender may be a single-band model with different controls from newer dual-band units. Use the exact model's quick installation guide, choose the new 2.4 GHz network when prompted, and enter its password carefully.

Use Tether or the web setup page

If WPS is unavailable or pairing fails, open Tether and add the extender, then follow the scan-and-select steps for the new router network. Some models also provide a browser setup page; the extender's manual gives the correct local address and default connection details.

Relocate and check the new connection

After configuration, move the extender to a position between the router and the weak area. Confirm the signal indicator remains healthy and reconnect your phone or laptop to the extended network if its name or password changed.

Common questions

Questions before you buy

How do I connect a TP-Link AC750 WiFi range extender?

Use WPS on the router and extender, or configure it in TP-Link Tether by selecting the router's WiFi and entering its password. Follow the guide for the exact model, since AC750 devices do not all share identical controls.

How do I connect a TP-Link 300Mbps WiFi range extender?

Check its model label, then use that model's setup guide to join the new router network, usually on 2.4 GHz. Enter the new WiFi password and confirm the extender's wireless status light shows a link.

Do I need to reset my TP-Link extender when I change routers?

Not always. You can often reconfigure it through Tether or its web interface; a factory reset is useful if the previous network settings cannot be changed or setup will not complete.

Why will my TP-Link extender not connect to the new WiFi?

Common causes include an incorrect password, WPS timing out, choosing an unsupported band, or trying setup too far from the router. Re-run setup close to the router and check the model-specific band and security requirements.
