How to Increase Internet Speed: 12 Proven Fixes for WiFi and Ethernet

To increase internet speed, start by running a baseline speed test on Speedtest by Ookla or Fast.com by Netflix, then systematically apply these proven fixes: restart your router, switch to a faster DNS provider like Cloudflare (1.1.1.1) or Google DNS (8.8.8.8), connect via Ethernet instead of WiFi, optimize your router placement, change your WiFi channel, and enable QoS settings. Most users see a 20 to 50 percent speed improvement without upgrading their plan.

Slow internet is not just annoying. It costs you real productivity, kills video calls mid-sentence, and turns a simple file download into a 20-minute ordeal. According to the FCC broadband standards updated in 2024, the minimum threshold for broadband is now 100 Mbps download and 20 Mbps upload. If you fall below that, your connection is officially substandard. The good news: most speed problems come from your local setup, not your ISP. Here is exactly how to diagnose and fix every common bottleneck, step by step.

Test Your Current Speed First

Before you change anything, you need a reliable baseline measurement. Without knowing your actual download speed, upload speed, and latency, you cannot tell whether any fix actually worked. Testing takes 60 seconds and gives you the data you need to make smart decisions.

Speedtest by Ookla (speedtest.net) is the industry standard used by ISPs, network engineers, and the FCC for broadband measurement. It tests download speed, upload speed, ping (latency), and jitter. Run it from a device connected via Ethernet to your router for the most accurate reading. WiFi introduces variables that can skew results by 30 to 60 percent depending on distance and interference.

Fast.com by Netflix provides a simplified speed test that specifically measures your throughput to Netflix servers. This is useful because it reveals whether your ISP throttles streaming traffic. If Fast.com shows significantly lower speeds than Speedtest by Ookla, your provider may be shaping traffic to specific services.

Run each test three times at different hours: morning, afternoon, and evening. Record every result. Your internet speed fluctuates based on network congestion in your neighborhood, especially during peak hours between 7 PM and 11 PM. If your speeds drop by more than 40 percent during peak hours, congestion on your ISP’s network is likely the bottleneck, not your home equipment.

When reading your results, focus on three numbers. Download speed determines how fast you can load web pages, stream video, and pull files. Upload speed affects video calls, cloud backups, and sending large attachments. Latency is the delay measured in milliseconds between your device and the test server. For general browsing, anything under 30 ms is excellent. For gaming, you want under 15 ms. Jitter is the variation in latency over time. High jitter (above 10 ms) causes choppy video calls and laggy gaming even when your raw speed looks fine.

12 Ways to Increase Internet Speed

These 12 fixes are ordered from easiest (takes 30 seconds) to most involved (requires spending money). Start at the top and work down. Most people solve their speed problem within the first five fixes without spending a cent.

1. Restart Your Router and Modem

Power cycling your router clears its memory cache, resets network tables, and forces it to renegotiate the cleanest available WiFi channels. Unplug both your modem and router from power, wait 30 seconds, plug the modem back in first, wait until all lights stabilize (about 2 minutes), then plug in the router. This single step resolves roughly 30 percent of home network speed issues. If your router has been running for weeks without a restart, accumulated memory fragmentation and stale routing tables are almost certainly degrading your throughput.

2. Switch to a Faster DNS Provider

DNS (Domain Name System) is the protocol that translates website names like bleebot.com into IP addresses your browser can connect to. Your ISP’s default DNS servers are often slow and overloaded. Switching to a dedicated DNS provider reduces page load times for every single website you visit. Cloudflare (1.1.1.1) and Google DNS (8.8.8.8) consistently deliver response times under 12 ms compared to 30 to 80 ms for typical ISP DNS. We cover the full DNS comparison with benchmarks in the dedicated section below.

3. Use Ethernet Instead of WiFi

Ethernet is a wired network connection using a physical cable between your device and router. It delivers consistent speeds with virtually zero packet loss, while WiFi speeds fluctuate based on distance, walls, interference from neighboring networks, and even microwave ovens operating on the 2.4 GHz band. A Cat 6 Ethernet cable costs under $10 and supports speeds up to 10 Gbps. For any stationary device like a desktop computer, gaming console, or streaming box, Ethernet should be your default connection. The speed difference is dramatic: where WiFi might deliver 200 Mbps at 15 feet from the router, Ethernet delivers your full plan speed consistently.

4. Optimize Router Placement

WiFi signals weaken with distance and are absorbed or reflected by physical obstacles. Your router should sit in a central, elevated location. Placing it on a shelf at chest height in the middle of your living space gives the best coverage. Avoid closets, cabinets, corners, and floors. Every wall between the router and your device cuts signal strength by 25 to 50 percent depending on material. Concrete and brick walls are the worst offenders, followed by mirrors and large metal surfaces. If your router currently sits behind your TV or inside a media cabinet, moving it to an open shelf can double your effective WiFi speed in distant rooms.

5. Change Your WiFi Channel

WiFi routers broadcast on specific channels within the 2.4 GHz and 5 GHz frequency bands. In apartments and dense neighborhoods, dozens of routers compete on the same channels, causing interference that tanks your speed. Use a free WiFi analyzer app (WiFi Analyzer on Android, or the built-in Wireless Diagnostics on macOS) to scan which channels are congested. For 2.4 GHz, channels 1, 6, and 11 are the only non-overlapping options. Pick whichever has the fewest competing networks. For 5 GHz, you have far more channels available, and interference is less common because the shorter range means fewer overlapping networks. Log into your router’s admin panel (usually 192.168.1.1 or 192.168.0.1) and manually set your channels instead of leaving them on auto-select.

6. Enable QoS Settings on Your Router

QoS (Quality of Service) is a router feature that prioritizes traffic from specific devices or applications. Without QoS, your router treats all traffic equally, meaning a background Windows update on one laptop can choke your video call on another device. Most modern routers include QoS settings in their admin panel. Enable it and set priority levels: put video conferencing and gaming at the top, streaming in the middle, and bulk downloads at the bottom. If you need to speed up Windows 11 performance overall, combining QoS with OS-level network optimizations delivers the best results.

7. Update Your Router Firmware

Router manufacturers release firmware updates that fix bugs, patch security vulnerabilities, and improve wireless performance. Many routers never get updated because users forget they exist. Log into your router’s admin panel and check the firmware version. Compare it to the latest version on the manufacturer’s website. Some routers support automatic updates. Enable that feature if available. Outdated firmware from 2022 or earlier may lack support for modern WiFi optimizations and security protocols, leaving your network both slower and more vulnerable.

8. Identify Bandwidth Thieves on Your Network

Bandwidth is the maximum data transfer capacity of your internet connection, measured in megabits per second (Mbps). Every connected device consumes a share of that capacity. Check your router’s admin panel for a list of connected devices. You may find devices you forgot about: old tablets, smart home devices constantly syncing, security cameras uploading footage, or even unauthorized devices if your WiFi password was shared or compromised. Disconnect anything you do not actively use. A single 4K security camera can consume 15 to 25 Mbps of constant upload bandwidth, which directly impacts every other device on your network.

9. Upgrade Your Router

If your router is more than 4 years old, it likely uses outdated WiFi standards that cap your maximum speed well below what your ISP delivers. The Wi-Fi Alliance certifies routers under the IEEE 802.11ax standard (marketed as Wi-Fi 6) and the newer IEEE 802.11be standard (Wi-Fi 7). A Wi-Fi 6 router purchased in 2026 costs between $60 and $150 and supports speeds up to 9.6 Gbps theoretical maximum. More importantly, Wi-Fi 6 handles multiple devices far better than older standards through technologies like OFDMA and MU-MIMO, which reduce congestion when 10 or more devices connect simultaneously. Check the WiFi standards comparison table below for specific speed differences.

10. Contact Your ISP

If you have optimized everything on your end and speeds still fall short, the problem sits with your ISP. Call their technical support line and request a line test. They can check signal levels on their end, identify node congestion, and dispatch a technician if needed. Ask specifically: “What speed tier am I provisioned for, and what are my current line signal levels?” If your modem’s signal-to-noise ratio (SNR) is below 30 dB for DSL or your cable modem shows uncorrectable errors above zero, there is a physical line issue that only the ISP can fix. Also ask about plan upgrades. ISPs frequently introduce faster tiers without notifying existing customers, and a simple plan change might double your speed for $10 to $20 more per month.

11. Install a Mesh WiFi System

A mesh network is a system of multiple WiFi access points that work together to blanket your entire home in a single, seamless wireless network. Unlike traditional WiFi extenders that cut your speed in half, mesh systems use dedicated backhaul channels between nodes to maintain full throughput. For homes larger than 1,500 square feet or multi-story buildings where a single router cannot reach every room, mesh is the most effective solution. Leading mesh systems from brands like Google Nest WiFi Pro, Eero, and TP-Link Deco support Wi-Fi 6E or Wi-Fi 7, delivering consistent speeds of 500 Mbps or more throughout a 4,000+ square foot home. The investment typically runs $200 to $400 for a 3-pack system.

12. Scan for Malware and Background Processes

Malware, adware, and poorly behaved applications can consume bandwidth without your knowledge. Cryptomining malware, botnet infections, and aggressive adware generate constant background traffic that degrades your internet speed. Run a full system scan with your antivirus software. On Windows, open Task Manager (Ctrl+Shift+Esc), click the Network column to sort by usage, and identify any process consuming bandwidth unexpectedly. If your device shows constant network activity even when you are not doing anything, malware or a misconfigured application is the likely cause. If you experience a WiFi connected but no internet situation after scanning, malware removal sometimes disrupts network adapter settings that require a quick reset.

WiFi Speed vs Ethernet Speed: What to Expect

Understanding the realistic speed you can achieve over WiFi versus Ethernet helps you set proper expectations and choose the right connection method for each device. WiFi standards have improved dramatically over the past decade, but even the latest Wi-Fi 7 protocol cannot match the consistency and raw throughput of a wired Ethernet connection under real-world conditions.

The theoretical maximum speeds listed by the Wi-Fi Alliance and IEEE 802.11 specifications assume perfect conditions: zero interference, single-device connection, short range, and wide channel bandwidth. Real-world WiFi speeds typically reach 30 to 50 percent of the theoretical maximum. Ethernet, by contrast, delivers 90 to 95 percent of its rated speed consistently because the physical cable eliminates interference entirely.

Wi-Fi 6E extends the Wi-Fi 6 standard into the 6 GHz frequency band, offering significantly more channels and less interference than the crowded 2.4 GHz and 5 GHz bands. This matters in apartment buildings and dense neighborhoods where dozens of networks compete for the same spectrum. Wi-Fi 7, certified under IEEE 802.11be, introduces 320 MHz channel widths and multi-link operation (MLO), which allows devices to transmit across multiple bands simultaneously. For most homes in 2026, a Wi-Fi 6 or Wi-Fi 6E router provides the best balance of performance, device compatibility, and price.

The key takeaway: use Ethernet for any device that stays in one place (desktops, game consoles, streaming boxes, NAS drives). Reserve WiFi for mobile devices like phones, tablets, and laptops where cables are impractical. This simple split lets you get the maximum performance your internet plan allows on your most demanding devices while still enjoying wireless convenience everywhere else.

DNS Optimization: A Free Speed Boost

DNS optimization is one of the fastest, free improvements you can make to your internet experience. Every time you type a URL or click a link, your device queries a DNS server to translate that domain name into an IP address. This lookup happens before any data loads. A slow DNS server adds 50 to 200 milliseconds of delay to every single page load, every API call, and every resource request on a webpage. Over hundreds of lookups per browsing session, that latency compounds into noticeably sluggish performance.

Your ISP assigns its own DNS servers by default, and these are frequently overloaded, poorly maintained, or geographically distant from your location. Switching to a dedicated third-party DNS provider is free and takes about 2 minutes. You can change DNS at the device level (in your network adapter settings) or at the router level (which applies to all devices on your network automatically).

Cloudflare (1.1.1.1) consistently ranks as the fastest public DNS resolver in independent benchmarks conducted by DNSPerf.com. Its global anycast network routes your queries to the nearest data center, minimizing round-trip time regardless of your location. Cloudflare also supports DNS over HTTPS (DoH) and DNS over TLS (DoT), which encrypt your DNS queries to prevent your ISP or anyone on your network from seeing which websites you visit.

Google DNS (8.8.8.8) offers the largest global infrastructure and the highest reliability. Google processes over 1 trillion DNS queries per day, and their servers have extremely low downtime. The slight speed difference compared to Cloudflare (14 ms vs 11 ms average) is imperceptible for most users. Google DNS also supports DoH and DoT encryption.

To change your DNS on Windows: open Settings, go to Network and Internet, click your active connection, click Edit next to DNS server assignment, switch from Automatic to Manual, enable IPv4, and enter your preferred DNS addresses. On macOS: open System Settings, click Network, select your connection, click Details, select DNS, and add the server addresses. If you are concerned about privacy while browsing, pairing a fast DNS with a best free VPN adds encryption to all your traffic, not just DNS queries.

When to Upgrade Your Internet Plan

Sometimes the problem is not your equipment or settings. Sometimes you genuinely need more bandwidth. If you have applied all 12 fixes above and your speed test results still match your plan’s advertised speed but that speed is not enough for your usage, an upgrade is the only solution. Here is how to determine whether you actually need a faster plan or whether you are paying for speed you will never use.

The FCC updated its broadband benchmark in March 2024 to 100 Mbps download and 20 Mbps upload, replacing the previous 25/3 Mbps standard that had been in place since 2015. This new benchmark reflects modern usage patterns including remote work, video conferencing, 4K streaming, and multi-device households. Use it as your minimum target.

For a household with 2 to 3 people doing standard activities (browsing, streaming, video calls), 100 to 200 Mbps is sufficient. A household with 4 or more people, multiple simultaneous 4K streams, gaming, and smart home devices should target 300 to 500 Mbps. Content creators uploading large files, households running home servers, or anyone with 15+ connected devices should consider gigabit (1,000 Mbps) plans. Fiber optic connections deliver the best performance because they offer symmetrical upload and download speeds with the lowest latency, typically under 5 ms.

Before upgrading, verify that your modem and router can actually handle faster speeds. A DOCSIS 3.0 cable modem caps out around 600 Mbps. You need DOCSIS 3.1 for gigabit cable internet. Similarly, a WiFi 5 router becomes the bottleneck if you upgrade to a 500 Mbps or faster plan. Match your equipment to your plan speed. Otherwise, you pay for speed your hardware cannot deliver.

If your WiFi shows a connection but loads nothing, the issue is different. Follow our WiFi connected but no internet fix first. A VPN can sometimes bypass ISP throttling on specific services like streaming or gaming.

Frequently Asked Questions

Why is my internet so slow even though I have a fast plan?

Your internet plan speed is the maximum your ISP delivers to your modem. Everything between the modem and your device can reduce that speed: an outdated router, WiFi interference from neighboring networks, distance from the router, network congestion during peak hours, or too many devices sharing bandwidth simultaneously. Test with Ethernet directly connected to your modem to isolate whether the bottleneck is your ISP or your home network.

Does changing DNS really make internet faster?

Changing DNS does not increase your raw download speed, but it significantly reduces the time your browser waits before starting to load each page. Faster DNS lookups from providers like Cloudflare (1.1.1.1) or Google DNS (8.8.8.8) shave 20 to 70 milliseconds off every page load compared to typical ISP DNS servers. Over a browsing session with hundreds of lookups, this creates a noticeably snappier experience.

Is WiFi 6 worth upgrading to in 2026?

Yes, upgrading to Wi-Fi 6 (IEEE 802.11ax) is worth it if your current router is more than 3 years old. Wi-Fi 6 delivers up to 3 times the real-world throughput of WiFi 5, handles 4 times as many simultaneous devices efficiently through OFDMA technology, and reduces latency by 75 percent in congested environments. Prices for quality Wi-Fi 6 routers start at $60, making it one of the highest-value home network upgrades available.

How often should I restart my router?

Restart your router at least once every 2 weeks for optimal performance. Routers accumulate memory fragmentation, stale DHCP leases, and routing table bloat over time, all of which degrade throughput. If you notice sudden speed drops, an immediate restart should be your first troubleshooting step. Some modern routers support scheduled automatic reboots through their admin panel, typically configurable for a low-usage time like 3 AM.

Can a VPN increase my internet speed?

A VPN typically reduces speed by 10 to 20 percent due to encryption overhead and routing through an additional server. However, a VPN can increase speed in one specific scenario: when your ISP throttles certain types of traffic like streaming or torrenting. The VPN encrypts your traffic so the ISP cannot identify and throttle it. If you suspect throttling, test your speed with and without a VPN to confirm.
