Your Kindle loses the WiFi signal because of a mismatch between what your device is trying to do and what your router allows
A Kindle that won't connect to WiFi usually sits stuck on "Connecting" or shows "Unable to connect" after you enter the password. The most common causes are: your router is using a WiFi standard your Kindle doesn't support, your password was entered wrong, your router is too far away or blocked by walls, or your Kindle's WiFi radio needs to be reset. The fastest fix is almost always to restart both devices — your Kindle and your router — in that order.
Before you start troubleshooting, write down your WiFi network name (the one you see when you search for networks on your phone) and your password exactly as it appears. Kindle passwords are case-sensitive, which means capital letters matter. If you are not certain of your password, log into your router's settings from a computer or phone first and check what it actually is.
Key Takeaways
- Restart your Kindle first, then restart your router, and wait 30 seconds before trying to connect again — this fixes most connection problems.
- Kindle devices only work on 2.4 GHz WiFi networks, not 5 GHz, so if your router broadcasts only 5 GHz you will need to change your router settings.
- Passwords are case-sensitive on Kindles, so entering "MyPassword" when it is actually "mypassword" will cause the connection to fail.
- If your Kindle is more than 30 feet from your router or separated by multiple walls, move closer and try again before assuming the device is broken.
Restart your Kindle and router in the right order
Restarting clears temporary glitches that prevent the WiFi radio from working. The order matters because your Kindle needs to find a fresh signal when it comes back on.
On your Kindle, hold the power button for 40 seconds until the screen goes black and you see a brief loading screen. Do not just tap the power button — hold it down. Wait 30 seconds for the device to fully restart, then try to connect to WiFi again from the WiFi menu. If that does not work, move to the next step.
Unplug your router from power for 30 seconds, then plug it back in. Wait two full minutes for it to finish starting up — you will see lights stop blinking when it is ready. Then go back to your Kindle and try to connect again. This restart clears your router's memory and forces it to broadcast a fresh signal.
Check that your router is broadcasting 2.4 GHz WiFi
Kindle devices only connect to 2.4 GHz networks. Many modern routers broadcast both 2.4 GHz and 5 GHz at the same time, but some routers are set to broadcast only 5 GHz, which your Kindle cannot see.
From a computer or phone connected to your WiFi, open a web browser and go to 192.168.1.1 or 192.168.0.1. You will be asked to log in — use the username and password printed on the back or bottom of your router. Once you are logged in, look for a section called "WiFi Settings", "Wireless", or "Radio". Find the setting that controls which frequency bands are active. If only "5 GHz" is checked, change it to "2.4 GHz" or "2.4 GHz and 5 GHz" (called dual-band mode). Save the changes and wait 30 seconds for the router to restart.
If you do not feel comfortable logging into your router settings, call your internet provider's support line — they can make this change for you over the phone.
Re-enter your WiFi password carefully
Kindle passwords are case-sensitive, which means "MyPassword" is different from "mypassword". A single wrong letter will cause the connection to fail silently — the Kindle will show "Unable to connect" without telling you why.
Go to your Kindle's WiFi settings and select your network name. When prompted for the password, type it exactly as it appears in your router settings. If you are not sure whether a letter should be capital, check your router settings first. On most routers, you can see the password by logging in at 192.168.1.1 and looking in the WiFi settings section. If you see the password is hidden as dots, you can usually click "Show password" to reveal it.
After you enter the password, wait 10 seconds before the Kindle tries to connect. If it still fails, delete the network from your Kindle's saved networks list and try again from scratch — sometimes the device remembers an old incorrect password.
Move your Kindle closer to the router
WiFi signal weakens with distance and through walls. If your Kindle is more than 30 feet away from your router, or separated from it by multiple walls or a floor, the signal may be too weak to connect reliably.
Temporarily move your Kindle to the same room as your router, within 10 feet, and try to connect. If it connects successfully, the problem is signal strength, not your device. You can then move the Kindle back to where you want to use it and either move the router to a more central location or consider a WiFi range extender to boost the signal in distant rooms.
Forget the network and reconnect from scratch
Sometimes your Kindle remembers an old connection setting that is now incorrect. Forgetting the network and reconnecting forces the device to start fresh.
On your Kindle, go to Settings, then WiFi. Find your network name in the list of saved networks, press and hold it (or tap the menu icon next to it), and select "Forget". Wait 10 seconds, then search for the network again and enter your password. This time the Kindle will create a completely new connection profile.
Check if your router has a device limit or MAC filtering enabled
Some routers have security settings that limit how many devices can connect or block specific devices by their hardware address. If you have added many devices to your network recently, your router may have reached its limit.
Log into your router at 192.168.1.1 and look for settings called "Device Limit", "Connected Devices", "MAC Filtering", or "Access Control". If MAC filtering is turned on, it means only devices on an approved list can connect — your Kindle may not be on that list. If a device limit is set, count how many devices are already connected. If you are at or near the limit, either remove an old device or raise the limit. If you are unsure how to change these settings, contact your internet provider.
Frequently Asked Questions
Why does my Kindle connect to WiFi at home but not at the coffee shop?
Public WiFi networks often require you to open a web browser and accept terms before you can use the internet. Kindles do not have a web browser, so they cannot complete this step. Some coffee shops have a separate "Kindle" network that does not require this, but most do not. Your Kindle will work on any home or office WiFi that does not require browser login.
Can I use a 5 GHz network if I split it into two bands?
Yes. If your router broadcasts both 2.4 GHz and 5 GHz at the same time (dual-band mode), your Kindle will see and connect to the 2.4 GHz band automatically. You do not need to do anything — just make sure both bands are turned on in your router settings.
What if my Kindle connects but then disconnects after a few minutes?
This usually means your Kindle is too far from the router or the signal is blocked. Move closer and try again. If it stays connected when you are near the router but disconnects when you move away, you need either to move your router or add a WiFi range extender to strengthen the signal in that room.
Does a factory reset fix WiFi problems?
A factory reset erases all your books and settings, so try every other step first. If nothing else works, you can factory reset by going to Settings, Device Options, and Reset. After the reset, set up your Kindle again and try to connect to WiFi. If it still will not connect, the WiFi radio itself may be broken and you may need to contact Amazon.
Why does my Kindle say "Incorrect password" when I know the password is right?
Check that you are not accidentally typing a space before or after the password — Kindles count spaces as part of the password. Also verify that Caps Lock is not on. If you are still stuck, reset your router password to something straightforward with no special characters, then try connecting again.
