Slow internet is one of the most frustrating things in modern life. You’re trying to work, stream, or just load a simple webpage, and everything crawls. Before you call your ISP and sit on hold for an hour, let’s walk through the fixes that actually work.
We’ve tested and verified all 15 of these methods. Some take 30 seconds, others take a bit more effort — but they cover pretty much every common cause of slow internet. Let’s get your connection back up to speed.
1. Restart Your Router and Modem
This is the classic “turn it off and on again” advice, and it works more often than you’d think. Routers run continuously for weeks or months, and over time they can develop memory leaks, overheating issues, and connection drops that a simple restart fixes.
How to do it properly:
- Unplug both your router and modem from the power outlet.
- Wait 30 seconds. Don’t skip this — it allows the capacitors to fully discharge and forces a fresh connection to your ISP.
- Plug in the modem first. Wait for all the lights to stabilize (usually 1-2 minutes).
- Plug in the router. Wait another 1-2 minutes for it to fully boot up.
- Test your speed.
If this fixed it, great. If not, consider setting your router to automatically restart once a week. Most modern routers have this option in their settings.
2. Run a Speed Test to Know Your Numbers
Before you go any further, you need to know what you’re working with. Run a speed test at speedtest.net or fast.com (Netflix’s speed tester).
Compare the results to what you’re paying for. If you’re paying for 200 Mbps and getting 180, that’s normal — ISPs advertise “up to” speeds. But if you’re getting 20 Mbps on a 200 Mbps plan, something is clearly wrong.
Test at different times of day too. If speeds drop significantly in the evening (7-11 PM), you’re dealing with network congestion — your neighborhood is all streaming Netflix at once. That’s an ISP infrastructure issue.
3. Move Closer to Your WiFi Router
WiFi signal degrades with distance and obstacles. Walls, floors, metal objects, and even large aquariums can weaken your signal significantly.
- Same room as router: You should get near-full speed.
- One wall away: Expect 50-75% of your speed.
- Two or more walls / different floor: Could drop to 25% or less.
If moving closer helps, your router placement is the issue. Position it centrally in your home, elevated (not on the floor), and away from thick walls and metal objects.
4. Switch to the 5GHz WiFi Band
Most modern routers broadcast two WiFi bands: 2.4GHz and 5GHz. The 2.4GHz band has better range but slower speeds. The 5GHz band is faster but doesn’t penetrate walls as well.
If you see two network names (like “MyNetwork” and “MyNetwork_5G”), connect to the 5GHz one when you’re within range. You’ll often see a noticeable speed boost.
If your router uses a single “smart” network name (band steering), you can usually force 5GHz in your device’s WiFi settings or log into the router and split the bands.
5. Change Your WiFi Channel
If you live in an apartment or dense neighborhood, your neighbors’ routers are probably competing for the same WiFi channels. This creates interference that slows everyone down.
How to change your channel:
- Log into your router. Usually it’s
192.168.1.1or192.168.0.1in your browser. Check your router’s sticker for the exact address and login. - Find the WiFi settings. Look for “Wireless” or “WiFi” in the menu.
- Change the channel. For 2.4GHz, try channels 1, 6, or 11 (they don’t overlap). For 5GHz, any channel works, but try a less congested one.
You can use a free WiFi analyzer app on your phone to see which channels are crowded in your area. Pick the least busy one.
6. Change Your DNS Servers
DNS (Domain Name System) is like the phonebook of the internet — it translates website names into IP addresses. Your ISP’s default DNS servers are often slow and overloaded. Switching to a faster DNS can make web pages load noticeably faster.
Best DNS servers for speed:
- Cloudflare DNS: 1.1.1.1 and 1.0.0.1 (fastest for most people)
- Google DNS: 8.8.8.8 and 8.8.4.4
- Quad9: 9.9.9.9 (good for security too)
How to change DNS on your device:
On Mac: System Settings > Network > WiFi > Details > DNS
On Windows: Settings > Network & Internet > WiFi > Properties > DNS server assignment
On iPhone/iPad: Settings > WiFi > tap the “i” > Configure DNS > Manual
On Android: Settings > Network & Internet > WiFi > tap the gear icon > Private DNS
You can also change DNS on your router to apply it to all devices on your network at once.
7. Use an Ethernet Cable Instead of WiFi
This is the most reliable way to get maximum speed. Ethernet eliminates all WiFi-related issues — interference, distance, congestion, everything.
If you have a desktop computer near your router, just plug it in. For laptops or devices in other rooms, consider powerline adapters (they send internet through your electrical wiring) or MoCA adapters (they use coaxial cables).
Even a cheap Cat5e cable supports up to 1 Gbps. If your router and device both support it, a Cat6 or Cat6a cable will handle multi-gigabit speeds.
8. Disconnect Unused Devices
Every device connected to your network shares your bandwidth. If you’ve got 15 smart home devices, three phones, two laptops, a smart TV, and a gaming console all connected — they’re all competing for the same pipe.
Check your router’s admin page to see all connected devices. Disconnect or pause any that aren’t actively being used. Most modern routers let you prioritize certain devices or create a guest network for IoT devices.
9. Update Your Router’s Firmware
Router manufacturers release firmware updates that fix bugs, improve performance, and patch security holes. But most people never update their router.
How to update:
- Log into your router’s admin page.
- Look for “Firmware Update,” “System Update,” or similar.
- Check for updates and install if available.
Some routers update automatically, but many don’t. This simple step can fix weird connectivity issues and improve overall performance.
10. Close Background Apps and Downloads
Your internet might be fine — it’s just that something else is hogging all the bandwidth. Common culprits:
- Cloud backups (iCloud, Google Drive, Dropbox, OneDrive) syncing large files
- Game updates downloading in the background (Steam, Epic Games, console updates)
- Windows or macOS updates downloading silently
- Other people on your network streaming 4K video or downloading files
- Malware using your connection for nefarious purposes
Check your device’s network activity. On Mac, open Activity Monitor and go to the Network tab. On Windows, open Task Manager and check the Network column. Sort by network usage to find the culprit.
11. Scan for Malware
Malware can eat your bandwidth by running background processes — botnets, crypto miners, data exfiltration, and adware all use your internet connection without you knowing.
Run a full system scan using your antivirus software. On Windows, Windows Defender is solid. On Mac, consider Malwarebytes (free version works fine for scanning). If anything turns up, remove it and retest your speed.
12. Clear Your Browser Cache and Extensions
Sometimes it’s not your internet — it’s your browser. A bloated cache, too many extensions, or an outdated browser can make web pages load slowly even on a fast connection.
Quick fixes:
- Clear cache: In Chrome, press Ctrl+Shift+Delete (or Cmd+Shift+Delete on Mac). Select “Cached images and files” and clear them.
- Disable extensions: Disable all extensions, test speed, then re-enable one by one to find the culprit. Ad blockers and VPN extensions are common causes.
- Try a different browser: If Chrome is slow, try Firefox or Edge. If the problem is browser-specific, you’ve found the issue.
- Update your browser: Always run the latest version.
13. Check for a VPN Slowing Things Down
VPNs route your traffic through remote servers, which adds distance and encryption overhead. This can reduce your speed by 20-50%, sometimes more if the VPN server is far away or overloaded.
If you’re using a VPN and experiencing slow speeds:
- Try a different server location (closer to you = faster)
- Switch to a VPN protocol like WireGuard or Lightway (faster than OpenVPN)
- Temporarily disconnect the VPN and test your speed to confirm it’s the cause
- Consider upgrading to a faster VPN provider
14. Upgrade Your Router or Internet Plan
If you’ve tried everything above and your internet is still slow, it might be time for a hardware or plan upgrade.
When to upgrade your router:
- It’s more than 4-5 years old
- It doesn’t support WiFi 6 (802.11ax) or WiFi 7 (802.11be)
- You have many devices and the router struggles to handle them
- Speeds are fine via Ethernet but terrible over WiFi
A WiFi 6 or WiFi 7 router can dramatically improve wireless performance, especially in homes with lots of devices.
When to upgrade your internet plan:
- You’re consistently getting the speeds you pay for, but they’re just not enough
- You have multiple people streaming, gaming, and video calling simultaneously
- You work from home and need reliable upload speeds
For most households in 2026, 200-500 Mbps is plenty. If you have heavy users (4K streaming, large file uploads, cloud gaming), look at gigabit plans.
15. Contact Your ISP (Last Resort)
If nothing else works, there’s a good chance the problem is on your ISP’s end. Common ISP-side issues include:
- Network congestion in your area (especially during peak hours)
- Throttling — some ISPs slow down specific types of traffic (streaming, torrents, etc.)
- Line issues — damaged cables, old infrastructure, or poor connections at the pole
- Account provisioning errors — your plan might not be configured correctly
- Outdated modem — if you’re renting an old modem from your ISP, it might not support current speeds
When you call, ask them to:
- Run a line test from their end
- Check for provisioning errors on your account
- Verify your modem supports the speeds you’re paying for
- Check for known outages in your area
If the phone support is useless (it often is), try reaching out via their social media (Twitter/X) or online chat. Those channels tend to get faster, more competent responses.
Bonus: Quick Diagnosis Checklist
Work through this in order to narrow down the problem fast:
- ✅ Restart router and modem → did it help?
- ✅ Run a speed test → how does it compare to your plan?
- ✅ Test with Ethernet → is it faster? (WiFi issue vs. ISP issue)
- ✅ Test on another device → is it slow on everything? (Network issue vs. device issue)
- ✅ Check for background downloads/updates → anything eating bandwidth?
- ✅ Change DNS → are webpages loading faster?
- ✅ Disable VPN → is that the culprit?
Most slow internet problems can be solved with steps 1-3. The rest handle edge cases and more persistent issues.
Frequently Asked Questions
Why is my internet slow at night but fast during the day?
Network congestion. Your neighbors are all streaming, gaming, and downloading during peak hours (typically 7-11 PM). Your ISP’s local infrastructure can only handle so much traffic. There’s not much you can do about this besides upgrading to a plan with dedicated bandwidth or switching to an ISP with better infrastructure in your area.
Will a new router make my internet faster?
It depends. If your current router is old or doesn’t support WiFi 6/7, upgrading can improve wireless speeds significantly. But a new router won’t help if your ISP plan is the bottleneck. Run a speed test with an Ethernet cable first — if speeds are still slow wired, the router isn’t the problem.
Is 100 Mbps fast enough?
For most people, yes. 100 Mbps handles 4K streaming, video calls, web browsing, and gaming without issues. It gets tight if multiple people are doing bandwidth-heavy activities simultaneously. For 3+ heavy users, 300+ Mbps is a better target.
Does mesh WiFi help with slow internet?
Mesh WiFi doesn’t increase your internet speed — it improves WiFi coverage. If you have dead zones or weak signal in parts of your home, mesh will help. If your speeds are slow everywhere, including near the router, mesh won’t fix the underlying problem.
Summary
Slow internet sucks, but most causes are fixable. Start with the basics — restart your router, run a speed test, check your WiFi signal. Work through the list, and you’ll likely find the culprit within the first few steps. If all else fails, it’s probably time to have a chat with your ISP or consider upgrading your hardware or plan.
Now go fix that connection. You’ve got this.
