How to Increase Internet Speed

Slow internet is rarely caused by one obvious thing. Your connection is a chain, your plan, your modem, your router, the Wi-Fi band, the channel, and your devices, and a weak link anywhere slows everything down. The good news is that most of the fixes are free, and the most effective one is often just moving your router. This guide works through them in order, from quick wins to knowing when it is genuinely time to upgrade.

Start by Finding the Bottleneck

Before changing anything, run a speed test so you know what you are working with. Plug a computer directly into the router with an Ethernet cable, sit close, and run a test at a site like speedtest.net.

If you first want to pin down why it is slow, our guide on why is my internet so slow reads the timing clues. Otherwise, compare the result to the speed you pay for. This tells you where the problem is:

• If the wired speed roughly matches your plan, your internet service is fine, and your problem is Wi-Fi. Focus on the wireless fixes below.
• If the wired speed is well below your plan, even over Ethernet, the issue is your modem, your line, or your plan, not your Wi-Fi. Skip to the upgrade section.

This five-minute check saves you from tweaking Wi-Fi settings when the real issue is elsewhere, or calling your provider when the real issue is your router placement.

The Free Fixes to Try First

• Restart your modem and router. Unplug both, wait 30 seconds, plug the modem back in first and let it fully connect, then plug in the router. This clears the device’s memory and resolves temporary glitches that quietly drag down speed. Doing it once a month is a good habit.
• Reposition your router. This is the single biggest free improvement for most homes, and people routinely gain 40 to 50 percent better Wi-Fi just from this. Your router is not a modem to be hidden, it needs open air. Put it in a central spot, elevated on a shelf or wall, out in the open. Keep it away from thick walls, metal objects, aquariums, microwaves, cordless phones, baby monitors, and Bluetooth speakers, all of which interfere. In a multi-story home, the middle floor is ideal.
• Disconnect what you are not using. Every connected device takes a share of your bandwidth, and idle phones, tablets, and smart gadgets still consume some in the background. Trimming the list frees capacity for what you are actually doing.

Optimize Your Wi-Fi

These changes target the wireless link, which is where most home slowdowns actually live.

• Use the right band. If your router is dual-band, connect nearby devices to the 5 GHz network, which is faster and far less congested than 2.4 GHz, though it does not travel as far. Use 2.4 GHz for devices that are far from the router or behind walls, where its longer range matters more than speed. If your router offers 6 GHz, even better for close, high-demand devices.
• Change your Wi-Fi channel. This is the most effective free fix in a crowded area like an apartment building. Wi-Fi channels are like radio stations, and if all your neighbors are on the same one, you are all fighting for it. Use a free Wi-Fi analyzer app on your phone to see which channels are congested, then log in to your router and switch to a quieter one. On 2.4 GHz, channels 1, 6, and 11 are the non-overlapping choices.
• Use Ethernet where you can. For stationary, demanding devices like a desktop, game console, or smart TV, a wired connection is typically two to ten times faster than Wi-Fi, with much lower lag. It is the best move for gaming, video calls, and large downloads, and it also frees up Wi-Fi capacity for everything else.

Tweak a Few Router Settings

• Update the firmware. Router firmware gets performance improvements and bug fixes, but routers rarely tell you. Log in to your router, find the firmware or update section, and install the latest version. Enable automatic updates if available.
• Turn on QoS. Many routers have a Quality of Service feature that prioritizes important traffic, like video calls and gaming, over background tasks. Enabling it keeps your meeting smooth even when someone else is downloading a large file.
• Secure your network. If neighbors are piggybacking on your Wi-Fi, they are eating your bandwidth. A strong password with WPA3 or WPA2 encryption keeps freeloaders off and your speed for yourself. Our guide on how to secure your Wi-Fi network walks through it.

Consider Faster DNS

Switching your DNS server can make websites feel more responsive, since DNS is what translates site names into addresses before a page loads. It does not increase your raw download speed, but it can cut the delay before pages start loading.

Set your DNS to Cloudflare (1.1.1.1 and 1.0.0.1), which is generally the fastest, or Google (8.8.8.8 and 8.8.4.4). On Windows, go to Settings, then Network and Internet, then your connection’s hardware properties, and edit the DNS assignment. On a Mac, it is under System Settings, then Network, then your connection’s details, then DNS.

When to Upgrade Hardware or Your Plan

Sometimes the fixes have a ceiling, and new hardware or a better plan is the honest answer.

If your router is more than about five years old, it may not be capable of modern speeds no matter how you configure it. Upgrading to a current Wi-Fi 6, 6E, or 7 router can transform performance, and a mesh system is worth considering for large or multi-floor homes where a single router cannot cover everything.

If your wired speed test consistently comes in below the plan you pay for, contact your provider, since the problem is on their side or in your equipment. And if your household has simply outgrown its plan, with many people streaming and gaming at once, a faster tier may be the realistic fix. One expectation to set: Wi-Fi rarely delivers the full advertised plan speed, since that figure usually reflects a wired connection under ideal conditions.

Conclusion

Faster internet usually does not require a new plan. Start by running a wired speed test to find the real bottleneck, then work the free fixes: restart your equipment, reposition the router out in the open, switch nearby devices to 5 GHz, move to a less congested channel, and wire up your demanding devices. Update your firmware, enable QoS, and secure your network. If you have done all that and a wired test still falls short of what you pay for, that is when new hardware or a call to your provider is the right next step.
