Key takeaways
- Uses your existing Wi-Fi, not mobile data, to extend coverage.
- It extends coverage, but may result in slower speeds than your router.
- Place the phone between the router and dead zone for best results.
I have a Pixel phone that usually sits in a drawer. I mostly use it to test new Android features for work, but sometimes I find creative ways to use or repurpose it. My latest experiment is fixing Wi-Fi dead zones.

You know... that one room or corner of your home where everything buffers, drops, or refuses to load. Most people fix this by buying a dedicated Wi-Fi extender or upgrading to a mesh system. But there's another option if you're like me and have an old Android phone laying around. You can turn it into a Wi-Fi extender, and it works well enough to deliver a usable connection in problem areas. The best part is it doesn't cost a thing to try.
How to fix spotty home Wi-Fi with an Android phone
What you'll need: All you'll need is an old Android phone with hotspot support, access to your home Wi-Fi network, and a charger to keep the device powered on while in use.
1. Connect your Android phone to your Wi-Fi network
The first step is to power on your old Android phone and connect it to your home Wi-Fi network as you normally would. Go to Settings > Network and internet > Internet and select the network.

Next, enable Android's Wi-Fi hotspot feature. This creates a new Wi-Fi network that other devices can connect to, but the phone essentially rebroadcasts your existing connection and serves as a basic Wi-Fi extender.
- On most Android phones, go to Settings > Network and internet > Hotspot and tethering, then enable Wi-Fi hotspot.
- On Samsung devices, go to Settings > Connections > Mobile Hotspot and Tethering, then enable Mobile Hotspot.

Tap the Wi-Fi hotspot setting you just enabled to configure it, including setting a custom network name and password. You can name it something similar to your main network. For example, if your main network is called "Skynet," you might name this one "Skynet Dead Zone."
Then set a strong password.

In the same Wi-Fi hotspot menu, you can adjust a few other options.
For example, you can enable a setting that turns off the hotspot automatically when no devices are connected. You can also choose a frequency, such as 2.4, 5, or even 6 GHz, which affects compatibility and connection speed. Some phones also let you enable instant connections for devices signed in to your Google account.
These tweaks can make a difference if you plan to use this setup long term.

If you're using an old phone, it likely doesn't have a SIM or an active cellular connection. But if it does, make sure it doesn't switch over to cellular data. You want the phone to share your home Wi-Fi connection with other devices, not use mobile data, which could eat into your plan and run up a bill.
Go to Settings > Network and internet > SIMs and turn off mobile data. You can also remove the SIM/eSIM entirely if the phone still has one installed.

Show more6. Place your phone between the router and the dead zone
You don't want to place your phone directly in the Wi-Fi dead zone.
Instead, position it somewhere between your router and the area where the signal drops off. It should be close enough to the router to maintain a strong connection, but far enough to extend coverage into the weak spot.
I had to move mine around a bit before finding the sweet spot. I also recommend keeping the phone plugged into a charger so it stays powered on continuously and doesn't shut off while extending your Wi-Fi. Once the Android phone is in place and charging, you can connect another device to the Wi-Fi hotspot network you've set up.
You can also test your connection speeds, such as with Ookla (owned by 's parent company, Ziff Davis).

Show moreFAQs
Will this improve my home Wi-Fi speed?
No. It extends your home Wi-Fi coverage, not speed. Your connection may even be slightly slower than your main network, but it's still very usable for browsing, streaming, and basic work.

Can any Android phone do this?
Most modern Android phones support Wi-Fi hotspot features.
Will this drain my Android phone's battery?
Yes, quickly. Keep the phone plugged in if you plan to use it as a permanent Wi-Fi extender.
Should I just buy an extender?
If you already have an old phone and just need basic coverage in one problem area, no. If you need reliable, high-speed performance across your home, a dedicated Wi-Fi extender or mesh system is better.
