Tablet Wi-Fi Slow: Speed Tests and Router Settings

Start With a Speed Test

To find out whether your tablet or your network is slowing things down, run an internet speed test on another device, such as a phone or laptop, while your tablet is experiencing the issue. Place both devices next to each other. If the second device shows a similar result, the slowdown is likely coming from your router or your internet connection. If the second device is noticeably faster, the tablet's Wi-Fi hardware or software is the bottleneck. For those considering a new router, Wi-Fi router guides can help you choose the right model.

Run the speed test several times to get a stable average. Note the time of day, as network congestion can vary. Also check the signal strength icon on your tablet. A weak signal means the tablet has to work harder to maintain a connection, which slows throughput. Moving a few feet closer to the router can make a big difference. For more detailed advice on signal issues, see our guide on tablet Wi-Fi signal drops. Also, make sure no other devices are downloading large files at the same time. A smart TV streaming video, a game console updating, or a desktop running backups can saturate your connection and make every other device feel slow. If you suspect this, pause those activities and rerun the test.

If the speed test shows that your tablet gets dramatically lower numbers than your phone even when both are idle and close together, the problem is likely inside the tablet. In that case, move on to the tablet-specific settings described later in this article.

Router Settings That Improve Throughput

Your router's configuration influences every device on your network. Start by checking if the router firmware is up to date. Manufacturers often release updates that fix bugs and improve performance. Then look at the wireless settings. Many routers have an auto channel selection, but in a dense environment, choosing a less congested channel manually can help. If you live in an apartment building or a neighborhood with many overlapping networks, interference is common. A channel that is overloaded will cause retransmissions and lower throughput.

If your router supports Quality of Service (QoS), enable it and give your tablet priority. QoS tells the router to prioritize traffic to specific devices, which can reduce lag and improve throughput for that device. Some routers allow you to set a bandwidth limit per device; make sure your tablet isn't throttled. Also make sure your router is positioned in a central location, away from walls, metal objects, and appliances like microwaves that can interfere with the signal. For more on router placement and troubleshooting, see optimize tablet Wi-Fi signal.

Another router feature to look for is band steering. If your router supports it, it can automatically move devices between the 2.4 GHz and 5 GHz bands (or 6 GHz if it's a tri-band router) based on signal strength and load. If band steering is disabled, your tablet might stay stuck on the slower band. Enable band steering and see if that improves throughput. If your router doesn't have band steering, you can manually connect your tablet to the faster band by creating a separate network name (SSID) for that band. Consult your router's documentation on how to do this; the exact steps vary by manufacturer.

Finally, consider the age of your router. An old router that only supports earlier Wi-Fi standards will cap the maximum speed for all devices, even newer ones. If your router is several years old and you've already changed settings, a new router might be the most effective fix. For guidance on Wi-Fi generations, see our comparison of Wi-Fi 6 vs Wi-Fi 5.

Tablet Settings to Try

On the tablet itself, start by forgetting the Wi-Fi network and then reconnecting. This clears any saved credentials or configuration glitches. Restart the tablet and the router at the same time. A simple restart often resolves temporary software issues that affect Wi-Fi. Android tablets rely on the connectivity stack provided by the Android Open Source Project, which includes Wi-Fi support, so keeping the system updated also helps. Check for system updates in your tablet's settings and install them if available.

Next, check if your tablet supports multiple frequency bands. Many modern routers broadcast on two bands: one with longer range but slower speeds, and another with higher speeds but shorter range. If your tablet can use the faster band, make sure it's connected to it. Some tablets let you choose a preferred band in the Wi-Fi settings. If you've been connecting to the slower band by default, switching can give you a noticeable boost. For a deeper look at band differences, see our comparison of Wi-Fi 6 vs Wi-Fi 5.

Another thing to check is whether your tablet has a power saving mode that disables Wi-Fi scanning or reduces network activity when the screen is off. Some tablets aggressively throttle background networking to save battery, which can make apps appear slow even when the connection is fine. Go to your tablet's battery settings and see if there's a high performance mode or a setting that keeps Wi-Fi active during sleep. Turning that on can prevent sudden drops in throughput when you resume using the tablet.

Also review which apps are running in the background. Some apps, like cloud sync services, can consume a lot of bandwidth even when you're not using them. You can set those apps to only sync over Wi-Fi when you're on an unmetered connection, or you can force stop them temporarily to see if throughput improves. For more on managing apps, see our guide on tablet app management.

Check for Interference and Physical Obstacles

Wi-Fi signals can be disrupted by many common household items. Cordless phones, baby monitors, microwave ovens, Bluetooth devices, and even thick walls and metal furniture can degrade the signal. If your tablet is slow in one room but fast in another, the difference is likely due to obstacles. Try moving the tablet to a different spot or repositioning the router to see if that helps.

If you have a mesh Wi-Fi system, make sure the satellite nodes are placed strategically. A mesh node that is too far from the main router or in a poor spot won't help. Some mesh systems have a placement test feature; use it to ensure each node has a strong backhaul connection. If you're using a range extender, note that range extenders often halve the wireless speed because they have to receive and retransmit the signal. A mesh system or a wired access point is generally more reliable. For more detailed troubleshooting of physical layer issues, refer to optimize tablet Wi-Fi signal.

Update Tablet Software and Apps

An outdated operating system or an old app can have bugs that affect network performance. Make sure your tablet's OS is updated to the latest version. On Android, this includes security patches and connectivity improvements. Similarly, individual apps may have known issues with high latency or slow downloads; updating them can resolve those issues. For apps that still run poorly, consider clearing the app's cache or reinstalling the app. See our guide on tablet app data clear cache for steps.

Some tablets also have a setting for Wi-Fi optimization or aggressive Wi-Fi handoff. If your tablet is switching between your router and a nearby access point too often, it can cause temporary slowdowns. Turn off any automatic network switching if you don't need it. Also, if you have a VPN app installed, try disconnecting it for a test. VPNs add overhead and can significantly reduce throughput, especially if the VPN server is far away. If the speed test improves without the VPN, you know it's the VPN causing the issue. For more on network troubleshooting, see our guide on tablet Wi-Fi not connecting.

What to pick for your use

Questions

How do I know if my tablet or my network is slow?

Run a speed test on another device in the same location. If that device is fast and your tablet is not, the tablet is the issue. If both are slow, the network or router is the problem.

Can router placement affect Wi-Fi speed on one tablet?

Yes. Walls, distance, and interference can weaken the signal. Moving the router or the tablet can improve speed.

What is QoS and how does it help?

Quality of Service is a router feature that prioritizes traffic to specific devices. By giving your tablet high priority, it can reduce lag and improve throughput.

Should I use a wired connection to test my Wi-Fi?

You can use a wired Ethernet connection to test your internet line speed, but it won't tell you about Wi-Fi performance. The speed test should be done over Wi-Fi to see what the tablet actually gets. A wired connection, such as through a USB Ethernet adapter, bypasses Wi-Fi. USB Power Delivery, defined by the USB-IF, is for charging and does not affect Wi-Fi.

My tablet is old and only supports an older Wi-Fi standard. Should I upgrade?

If you've confirmed other fixes don't help, upgrading to a tablet with a newer Wi-Fi chip can significantly improve performance. Compare models in our buying guides.

Why does Wi-Fi speed vary by app?

Some apps are optimized to use less bandwidth or may be limited by their servers. Also, background apps can consume bandwidth. Check which apps are running and close those you don't need.
