Start with what's slowing you down
Before you change anything, you need to know whether the problem is your internet plan, your equipment, or how you're using the connection. These are three different fixes, and doing the wrong one wastes time.
Run a speed test on the device that feels slow — the same one you tested from before. If the result matches what your internet provider promises you're paying for, the issue is not your connection speed itself. It's either interference, too many devices online at once, or something running in the background on that device. If the speed test shows significantly less than your plan promises, then your equipment or setup needs attention.
Write down the speed test result and the plan speed from your bill. You'll use both to figure out what to try next.
Key Takeaways
- Moving your router to a central, elevated location away from walls and metal objects can improve speed by reducing interference.
- Restarting your modem and router clears temporary problems and takes two minutes — try this before anything else.
- Switching to a less crowded Wi-Fi channel or using the 5 GHz band instead of 2.4 GHz often fixes slowness in apartments or dense neighborhoods.
- Too many devices streaming or downloading at once will slow everything down, even if your plan speed is fine.
- If speed tests show you're getting less than 80 percent of your plan speed, contact your provider to check for line problems.
Restart your modem and router first
This fixes more problems than any other single step, and it takes two minutes. A modem and router that have been running for weeks or months can get stuck in a state where they're not communicating properly with your provider's network.
Unplug the power cable from the back of your modem — the device your provider installed or the one you own that connects to the wall outlet or cable line. Wait 30 seconds. Plug it back in and wait two to three minutes for the lights to stop blinking and settle into a steady pattern. Then do the same with your router — unplug it, wait 30 seconds, plug it back in, and wait for the lights to stabilize.
Once both devices are fully restarted, run another speed test. Many people see improvement right here. If you don't, move to the next step.
Move your router to a better location
Wi-Fi travels through air but gets blocked or weakened by walls, metal, and water. A router hidden in a closet, behind a TV, or in a corner of your home will deliver slower speeds than one in the open.
Move your router to a central location in your home — ideally in the middle of the space rather than at one end. Elevate it off the floor: place it on a shelf, a desk, or a wall mount rather than on the ground. Keep it away from metal objects like filing cabinets, refrigerators, and microwave ovens, which reflect Wi-Fi signals. Keep it away from thick walls, especially concrete or brick.
If you have a two-story home, place the router on the first floor roughly in the center, or on the second floor if most of your devices are upstairs. Run another speed test from the room where you usually work or stream. You may see a noticeable difference, especially if your router was previously hidden or in a corner.
Check what's using your connection right now
Even if your plan speed is fast, slowness happens when too many things are using the connection at the same time. A video call, a large read, and a streaming service running simultaneously will all compete for the same bandwidth.
Look at what's running on your device. Close web browser tabs you're not using. Pause or stop any downloads, cloud backups, or streaming services. On your phone or computer, check the settings for apps that might be syncing in the background — cloud storage, email, and social media apps often do this without you noticing.
Ask anyone else in your home to pause streaming or gaming for a few minutes. Run a speed test again. If the speed jumps up significantly, you've found the problem: your plan is fine, but you need to manage how many things use the connection at once, or you need a faster plan to handle everything simultaneously.
Switch Wi-Fi channels or bands
Wi-Fi channels are like lanes on a highway. If your neighbors' routers are all using the same channel, you're all competing for the same space and speeds drop. Most routers use either the 2.4 GHz band or the 5 GHz band, and you can often switch between them or use both at once.
The 2.4 GHz band travels farther through walls but is more crowded — many devices use it, and so do microwaves and cordless phones. The 5 GHz band is faster but doesn't travel as far. If you're close to your router, switching to 5 GHz often helps.
Log into your router's settings. This usually means typing your router's IP address (often 192.168.1.1 or 192.168.0.1) into a web browser, or using your router manufacturer's app. Look for Wi-Fi settings or wireless settings. You should see the name of your network and options for the band or channel. Try switching to 5 GHz if you're currently on 2.4 GHz and you're within 30 feet of the router. If you see a list of channels, try channels 1, 6, or 11 on 2.4 GHz — these don't overlap with each other, so they cause less interference.
Reconnect your device to the network with the new settings and run another speed test. Many people in apartments or dense neighborhoods see improvement here because they're moving away from the crowded channels their neighbors are using.
Check for background programs and updates
Your device itself might be using your connection without you knowing. Windows and Mac computers often read and install updates in the background. Antivirus software, cloud backup services, and streaming apps can all consume bandwidth.
On Windows, open Settings, go to System, then About, and look for "Update status." If an update is downloading or installing, that's using your bandwidth. Let it finish or pause it temporarily while you test. On Mac, go to System Settings, then General, then Software Update to check the same thing.
Check your router's settings or app to see which devices are connected and how much data each one is using. Many modern routers show this information. If you see a device using a lot of bandwidth that you didn't expect, disconnect it or restart it.
Contact your provider if nothing improves
If you've restarted your equipment, moved your router, closed background programs, and your speed test still shows less than 80 percent of what you're paying for, the problem is likely on your provider's side — a line issue, a problem at the neighborhood node, or equipment failure.
Call your internet provider's technical support line. Tell them your plan speed, your current speed test result, and what you've already tried. They can run diagnostics on your line from their end and tell you whether the issue is in your home or on their network. If it's on their network, they'll schedule a technician visit or fix it remotely. If it's in your home, they can walk you through more advanced troubleshooting or replace your modem if it's failing.
Have your account number and the address where the service is installed ready when you call. The faster you can describe the problem — "I'm getting 25 Mbps but I'm paying for 100 Mbps" — the faster they can help.
Frequently Asked Questions
Why is my speed slower on Wi-Fi than when I plug in with an ethernet cable?
Wi-Fi is always slower than a wired connection because the signal has to travel through air and gets weakened by walls and interference. If the difference is huge — like 100 Mbps on ethernet but 20 Mbps on Wi-Fi — your router location or channel choice needs adjustment. If the difference is small, that's normal.
Does restarting my router really help, or is that just what tech support always says?
Restarting actually fixes real problems. Routers can get stuck in a state where they're not communicating properly with your provider's equipment, or they can overheat and slow down. It's the first thing to try because it works often enough to save you hours of troubleshooting.
Will a new router make my internet faster?
Only if your current router is very old or broken. A new router won't increase your plan speed — your provider controls that. But a newer router with Wi-Fi 6 or Wi-Fi 6E can deliver that speed more reliably and handle more devices at once without slowing down.
What's the difference between my router and my modem?
Your modem connects to your provider's network and converts their signal into internet. Your router takes that internet and broadcasts it as Wi-Fi to your devices. You need both. Some devices combine them into one unit called a gateway.
Can I make my internet faster by changing my password?
No. Changing your Wi-Fi password won't affect speed. But if your network is unsecured and neighbors are connecting to it without permission, that will slow things down. Make sure your router is password-protected with a strong password.
