How to Fix Slow Internet Speed: 20 Fast Fixes That Work

The fastest way to fix slow internet speed is to restart your modem and router, run a speed test, check whether the slowdown happens on one device or every device, and then test with an Ethernet cable if possible. If wired speed is good but Wi-Fi is slow, the problem is usually signal strength, router placement, interference, or too many connected devices. If wired speed is also slow, check for an outage, damaged cables, an overloaded modem, or an issue with your internet provider.

Start with the simple fixes below. Most slow internet problems come from one of five places: your router, Wi-Fi signal, device, background apps, or your internet service plan.

Before You Change Anything: Find Out What Is Actually Slow

When someone asks, “why is my internet so slow?” the answer is not always the internet itself. Sometimes the Wi-Fi is weak. Sometimes only one laptop is struggling. Sometimes a game launcher, cloud backup, phone update, VPN, or browser extension is quietly eating bandwidth.

Use this quick check first:

For reference, the FCC’s current fixed broadband benchmark is 100 Mbps download and 20 Mbps upload, which is a useful baseline when comparing your plan to your real-world needs. The FCC also notes that different online activities need different speeds, so a plan that works for email may not feel good for 4K streaming, gaming, or multiple video calls.

Step 1: Restart Your Modem and Router the Right Way

This sounds too simple, but it works often because routers and modems can get stuck with memory issues, old sessions, heat, or temporary connection errors.

How to restart your internet equipment

1. Unplug the modem and router from power.
2. Wait at least 30 seconds.
3. Plug in the modem first.
4. Wait until the modem lights become stable.
5. Plug in the router.
6. Wait 2–5 minutes, then test again.

If you use a combined modem/router gateway, unplug that single device, wait, then reconnect it.

When this fix helps most

Restarting often helps when:

• Internet suddenly became slow today
• Wi-Fi connects but pages load slowly
• Streaming buffers even near the router
• Your router has not been restarted in weeks
• Speeds drop after several days of normal use

If the speed improves for a few hours and then becomes slow again, the router may be overheating, outdated, overloaded, or failing.

Step 2: Run a Proper Speed Test

A speed test is useful only if you run it correctly. Do not test while someone is streaming 4K video, downloading a large game, backing up photos, or joining a video call.

Best way to test internet speed

Do this in order:

1. Stand near the router and run a speed test on Wi-Fi.
2. Connect a computer directly to the router with Ethernet and test again.
3. Compare both results with your internet plan.
4. Test at different times of day.
5. Write down download speed, upload speed, and ping.

What the results mean

• Download speed affects streaming, web browsing, app updates, and file downloads.
• Upload speed affects video calls, sending files, cloud backups, live streaming, and online work.
• Ping/latency affects gaming, video calls, and how “instant” websites feel.
• Jitter means latency is unstable, which can cause choppy calls even when speed looks fine.

If your Ethernet speed is close to your plan but Wi-Fi is poor, your provider is probably not the main issue. Focus on router placement, Wi-Fi bands, interference, or mesh coverage.

Step 3: Check for Background Apps Using Bandwidth

One of the most overlooked fixes is checking what your device is doing in the background. A computer can feel like it has bad internet when it is actually busy downloading updates, syncing files, or uploading backups.

This is especially helpful when you are wondering, “why is my internet so slow on my computer but not other devices?”

On Windows 10 or Windows 11

Press Ctrl + Shift + Esc to open Task Manager.

Then:

1. Click Processes.
2. Click the Network column.
3. Look for apps using data.
4. Pause or close anything unnecessary.

Common bandwidth hogs include:

• Steam, Epic Games, Xbox app, Battle.net
• OneDrive, Google Drive, Dropbox, iCloud
• Windows Update
• Torrent apps
• Video meeting apps running in the background
• Browser tabs playing media
• Security tools performing cloud checks

For deeper detail, open Resource Monitor, go to the Network tab, and check which processes are sending or receiving data.

On Mac

Open Activity Monitor, then click the Network tab. Look for apps with high “Sent Bytes” or “Rcvd Bytes.”

On Android or iPhone

Check app data usage in settings. Social media apps, cloud photo backup, system updates, and video apps can run heavily in the background.

Step 4: Move Your Router Before Buying Anything

If your Wi-Fi is slow, router location matters more than many people think.

A router hidden in a closet, behind a TV, under a desk, beside a microwave, or near thick walls will usually perform worse. Wi-Fi signals weaken when they pass through brick, concrete, metal, mirrors, floors, and large appliances.

Best router placement

Place your router:

• Near the center of your home
• On a shelf or table, not the floor
• Away from metal objects
• Away from microwaves and baby monitors
• In an open area
• Close to where people use the internet most

Bad router placement

Avoid putting your router:

• Inside a cabinet
• Behind the sofa
• In a basement corner
• Next to the TV box and cables
• Near cordless phone bases
• Beside thick walls or large mirrors

If moving the router fixes the issue, you do not need a new plan. You needed better Wi-Fi coverage.

Step 5: Switch Between 2.4 GHz, 5 GHz, and 6 GHz Wi-Fi

Many slow Wi-Fi problems happen because the device is connected to the wrong Wi-Fi band.

2.4 GHz vs 5 GHz vs 6 GHz

If you are close to the router, use 5 GHz or 6 GHz. If you are far away or behind walls, 2.4 GHz may be more stable.

Wi-Fi 6E uses the 6 GHz band, which can reduce congestion compared with older crowded bands, especially in places with many nearby networks.

Practical example

If your laptop is in the same room as the router but still connected to 2.4 GHz, your speed may be much lower than expected. Switch to 5 GHz and test again.

If your bedroom is two walls away and 5 GHz keeps dropping, 2.4 GHz may feel slower on paper but more reliable in real life.

Step 6: Fix “WiFi Slow on Laptop” Problems

When WiFi slow on laptop issues appear but phones and TVs work fine, the laptop is usually the problem.

Try these laptop fixes

1. Restart the laptop.
2. Move closer to the router.
3. Forget the Wi-Fi network and reconnect.
4. Turn off VPN temporarily.
5. Close cloud sync apps.
6. Update the Wi-Fi driver.
7. Disable battery saver mode during video calls.
8. Check Task Manager for network usage.
9. Try another browser.
10. Test with Ethernet or a USB Wi-Fi adapter.

Why laptops often slow down

Laptops can have weak internal antennas, outdated Wi-Fi drivers, old network cards, power-saving settings, or background programs using bandwidth.

If the laptop gets full speed with Ethernet but poor speed on Wi-Fi, consider updating the Wi-Fi adapter driver or using a better USB Wi-Fi adapter.

Step 7: How to Fix Slow Internet Speed on PC

If you came here specifically for how to fix slow internet speed on PC, use this checklist.

PC internet speed checklist

• Restart your PC and router.
• Use Ethernet for testing.
• Open Task Manager and sort by Network.
• Pause Windows updates while you work.
• Turn off VPN and proxy settings temporarily.
• Update your network adapter driver.
• Clear browser cache.
• Disable unnecessary browser extensions.
• Run a malware scan.
• Flush DNS.
• Reset network settings if nothing else works.

Flush DNS on Windows

A DNS problem can make websites feel slow even when your download speed is fine.

Open Command Prompt as Administrator and run:

ipconfig /flushdns

Microsoft recommends network commands such as resetting TCP/IP, releasing and renewing the IP address, and flushing the DNS resolver cache when fixing Wi-Fi connection issues in Windows.

Reset network settings on Windows

Use this only after simpler fixes.

Go to:

Settings > Network & internet > Advanced network settings > Network reset

After resetting, Windows will remove and reinstall network adapters. You may need to reconnect to Wi-Fi afterward.

Step 8: How to Fix Slow Internet Speed Windows 10

For Windows 10 users, slow speed can happen after updates, driver changes, DNS issues, or background downloads.

Windows 10 fixes

1. Open Task Manager and check the Network column.
2. Pause large downloads and cloud sync.
3. Go to Settings > Update & Security and check if Windows Update is active.
4. Open Device Manager > Network adapters and update the Wi-Fi driver.
5. Forget and reconnect to your Wi-Fi network.
6. Run the built-in network troubleshooter.
7. Flush DNS.
8. Reset the network if needed.

A useful trick: if you are on limited bandwidth, set the connection as metered. This can reduce some automatic background downloads.

Step 9: How to Fix Slow Internet Speed Windows 11

Windows 11 has similar fixes, but the menus are slightly different.

Windows 11 fixes

1. Go to Settings > Network & internet.
2. Check whether you are connected to Wi-Fi or Ethernet.
3. Click Advanced network settings.
4. Disable and re-enable the network adapter.
5. Run the network troubleshooter.
6. Check for driver updates.
7. Use Task Manager to stop bandwidth-heavy apps.
8. Flush DNS using Command Prompt.
9. Use Network reset as a last step.

If the issue started after a recent update, check whether your Wi-Fi driver also has an update from the laptop manufacturer.

Step 10: How to Fix Slow Internet Speed on Android

If you want to know how to fix slow internet speed on Android, start by finding out whether the problem is Wi-Fi, mobile data, or only one app. If your phone shows Wi-Fi connected but websites or apps still will not load, follow this detailed guide on phone connected to WiFi but no internet to fix Android and iPhone Wi-Fi connection problems.

Android Wi-Fi fixes

1. Restart your Android phone.
2. Toggle Airplane mode on and off.
3. Forget the Wi-Fi network and reconnect.
4. Move closer to the router.
5. Switch between 2.4 GHz and 5 GHz.
6. Turn off VPN.
7. Disable Data Saver temporarily.
8. Clear cache for the slow app.
9. Update Android and your apps.
10. Reset network settings if nothing works.

Why is my internet so slow on my Android phone?

Your Android phone may be slow because of weak Wi-Fi signal, background app updates, too many open apps, VPN filtering, low storage, data saver mode, poor mobile signal, or a router issue.

How to boost internet speed on Android phone

To boost internet speed on Android phone, connect to 5 GHz Wi-Fi when near the router, remove unused apps, stop auto-updates during work hours, turn off VPN when not needed, and reset network settings if the phone is the only slow device.

Step 11: How to Fix Slow Internet Speed on Mobile

For anyone asking how to fix slow internet speed on mobile, use the same logic: test Wi-Fi and mobile data separately.

Mobile internet fixes

• Restart the phone.
• Turn Airplane mode on for 10 seconds, then off.
• Move to a stronger signal area.
• Switch from Wi-Fi to mobile data, then compare.
• Turn off VPN.
• Close background apps.
• Update the phone.
• Remove unused apps.
• Reset network settings.
• Check whether your plan has a data limit or reduced speed after heavy usage.

How to increase net speed in mobile

To increase net speed in mobile, keep your phone updated, use 5 GHz Wi-Fi near the router, clear app cache, remove unused apps, avoid running many downloads at once, and make sure your phone is not in battery saver or data saver mode during video calls or downloads.

Step 12: Fix Slow Internet Download Speed

If browsing feels okay but downloads are slow, the cause may not be your whole internet connection.

How to fix slow internet download speed

Try this:

1. Test download speed from more than one website.
2. Pause other downloads.
3. Turn off VPN.
4. Try Ethernet.
5. Restart the router.
6. Check available storage on your device.
7. Try another browser.
8. Disable browser extensions.
9. Clear browser cache.
10. Check whether the download server is limiting speed.

Important note

A single file download can be slow because the website’s server is busy or limiting traffic. Your internet can be fine while one download source is slow.

Step 13: Check Your Cables

Loose or damaged cables can cause unstable speeds, especially with cable internet.

Check:

• Coax cable from wall to modem
• Ethernet cable from modem to router
• Ethernet cable from router to PC
• Power adapter
• Splitters
• Wall jack

Replace old Ethernet cables if they are damaged, bent sharply, or very old. For gigabit internet, use at least Cat 5e or Cat 6 Ethernet cable.

If your speed is much better with a new cable, you found the problem.

Step 14: Disconnect Devices You Are Not Using

Every connected device can use some bandwidth. Smart TVs, phones, tablets, laptops, cameras, speakers, consoles, and smart home gadgets may all be connected at the same time.

Common hidden bandwidth users

• Smart TVs updating apps
• Game consoles downloading patches
• Phones backing up photos
• Security cameras uploading video
• Cloud storage syncing files
• Kids streaming video in another room
• Old tablets left connected
• Smart speakers and displays

Log in to your router app and check connected devices. Remove anything you do not recognize.

If you suspect neighbors, guests, or unknown devices are using your network, change your WiFi password; du users can follow this step-by-step guide on how to change du WiFi password.

Step 15: Change the Wi-Fi Channel

If you live in an apartment, dorm, townhouse, or busy neighborhood, nearby routers may crowd the same Wi-Fi channels.

Best 2.4 GHz channels

For 2.4 GHz Wi-Fi, channels 1, 6, and 11 are commonly used because they do not overlap with each other.

What to do

• Open your router app or admin page.
• Check Wi-Fi settings.
• Change the 2.4 GHz channel to 1, 6, or 11.
• For 5 GHz, try automatic channel selection first.
• Restart Wi-Fi and test again.

Modern routers often manage channels automatically, but manual changes can help in crowded buildings.

If you use Ubiquiti gear, especially the UniFi U6 Pro, follow our detailed guide on fastest WiFi speed settings for UniFi U6 Pro to tune channel width, 5 GHz settings, transmit power, and wireless stability.

Step 16: Update Router Firmware

Router firmware is the software inside your router. Updates can improve stability, security, speed, and compatibility.

How to update

1. Open your router app or admin panel.
2. Find Firmware, Software Update, or Router Update.
3. Install available updates.
4. Restart the router.
5. Test speed again.

If your router is from your provider, you may not control updates manually. In that case, restart it and ask your provider whether the gateway is current.

Step 17: Use Ethernet for Important Devices

Wi-Fi is convenient, but Ethernet is usually more stable.

Use Ethernet for:

• Work computers
• Gaming PCs
• Streaming boxes
• Smart TVs
• Desktop PCs
• Home office setups
• Large downloads
• Video calls

Even one wired device can improve the whole network because it reduces Wi-Fi traffic.

If your router is far away, consider a mesh system with Ethernet backhaul, MoCA adapters, or a professionally installed Ethernet line.

Step 18: Consider Mesh Wi-Fi or a Better Router

A Wi-Fi extender can help in small areas, but a mesh Wi-Fi system is usually better for larger homes.

Extender vs mesh

When to upgrade your router

Upgrade your router if:

• It is more than 5 years old
• It cannot handle your internet plan
• It disconnects often
• It has no firmware updates
• It struggles with many devices
• You upgraded to gigabit internet but still use an old router

A new internet plan will not fix an old router that cannot deliver the speed.

Step 19: Turn Off VPN When You Do Not Need It

VPNs can protect privacy and help with work access, but they can also slow internet speed because your traffic travels through another server.

Try turning off your VPN and testing again.

If speed improves, use a closer VPN server or only enable VPN when needed.

VPN slowdown is common during:

• Video calls
• Gaming
• Large downloads
• Streaming
• Cloud file transfers

Step 20: Scan for Malware and Remove Junk Software

Malware, adware, and unwanted browser extensions can make your internet feel slow.

Warning signs

• New tabs open by themselves
• Browser homepage changed
• Pop-ups appear often
• Unknown extensions are installed
• PC fan runs constantly
• Data usage is high for no clear reason
• One device is slow while others are fine

Run a trusted security scan, remove suspicious extensions, and uninstall programs you do not use.

Comcast Internet Speed Slow: How to Fix It

If you are a Comcast/Xfinity customer and your internet speed is slow, use this order:

1. Restart your modem or Xfinity gateway.
2. Check the Xfinity app for outages.
3. Run a speed test near the gateway.
4. Test with Ethernet if possible.
5. Check whether too many devices are connected.
6. Tighten coax and Ethernet cables.
7. Remove unnecessary splitters.
8. Contact Xfinity if wired speed is far below your plan.

Xfinity says customers can use its troubleshooting tools and outage map to check service problems and begin troubleshooting.

If your modem is old or rented, ask whether it supports your current plan. A modem that worked years ago may not be ideal for a faster plan today.

Why Is My Internet So Slow on My Computer But Not Other Devices?

This is one of the most useful clues. If only your computer is slow, your router and internet plan are probably not the main problem.

Most common causes

• Background downloads
• Windows Update
• Cloud backup
• VPN
• Bad Wi-Fi driver
• Weak laptop Wi-Fi card
• Browser extensions
• Malware
• DNS cache problem
• Low storage
• Too many startup apps

Best fix order

1. Restart the computer.
2. Check Task Manager.
3. Pause sync apps.
4. Try another browser.
5. Flush DNS.
6. Update Wi-Fi driver.
7. Test Ethernet.
8. Run a malware scan.
9. Reset network settings.

If Ethernet is fast and Wi-Fi is slow only on that computer, the Wi-Fi adapter or driver is likely the issue.

Why Is My WiFi So Slow Even With Fast Internet?

Fast internet and fast Wi-Fi are not the same thing.

Your provider may deliver high speed to your modem, but your phone or laptop may receive weak Wi-Fi because of distance, walls, interference, or router limits. For a deeper step-by-step guide, read our full tutorial on how to boost your WiFi signal and improve coverage in every room.

Reasons Wi-Fi feels slow

• Router is too far away
• Thick walls block signal
• Device is on 2.4 GHz in a crowded area
• Router is old
• Too many devices are connected
• Neighbor networks cause interference
• Firmware is outdated
• Device Wi-Fi card is weak
• Router is hidden in a cabinet
• Mesh nodes are placed too far apart

Simple Wi-Fi improvement plan

• Move router to a central open area.
• Use 5 GHz when close.
• Use 2.4 GHz when far.
• Wire important devices.
• Add mesh for large homes.
• Update router firmware.
• Remove unknown devices.

When You Should Call Your Internet Provider

You should contact your provider when:

• Wired Ethernet speed is far below your plan
• Internet drops many times per day
• Modem lights show connection errors
• Speeds are slow on every device
• You already replaced cables
• Your provider’s outage page shows no issue but service is poor
• Your modem is old or not approved for your plan
• You hear static or see damage on outside lines

Before calling, collect:

• Speed test results
• Time of day when slowdown happens
• Wired and Wi-Fi test results
• Modem/router model
• Screenshot of your plan speed
• List of troubleshooting steps already done

This makes support much easier because you can say, “I tested with Ethernet and still get much lower speed than my plan.”

Advanced Fixes for Stubborn Slow Internet

Use these if the basic steps did not solve the issue.

1. Change DNS

Try a reputable DNS provider if websites take a long time to start loading.

Popular options include:

• Cloudflare DNS
• Google Public DNS
• Quad9 DNS

2. Enable QoS or SQM

Some routers have QoS or Smart Queue Management. These features can help reduce lag when one person is uploading, streaming, or downloading heavily.

This is helpful for gaming, Zoom, Teams, and online classes.

3. Separate smart home devices

Put smart home gadgets on 2.4 GHz and keep laptops, phones, and streaming devices on 5 GHz or 6 GHz.

4. Replace old modem

If your modem cannot support your plan, it becomes a bottleneck.

5. Check for overheating

Routers need airflow. If your router feels hot, move it to an open area and keep it upright if designed that way.

A Simple 15-Minute Troubleshooting Plan

Use this when you want the fastest path without getting overwhelmed.

Minute 1–3: Restart

Restart modem, router, and the slow device.

Minute 4–6: Test

Run a speed test near the router.

Minute 7–9: Compare

Test another device. If only one device is slow, focus on that device.

Minute 10–12: Check background usage

Open Task Manager, Activity Monitor, or phone data usage.

Minute 13–15: Try a better connection

Switch Wi-Fi bands or connect with Ethernet.

If the problem continues after this, move into the deeper fixes above.
