If you notice your Wi-Fi is choppy, web pages load slowly, or you get kicked out of online games due to network latency , you're not alone. We often blame the internet provider, but the reality is that, with the same contracted speed, you can have a very different experience simply by changing your router and properly configuring your network.

As is common with many people who "change routers more often than internet providers," a good trick is to fine-tune your router's settings : network name, power, channels, DNS, firmware, and location. You don't need to be a network engineer: with a few clear ideas and some common sense, your connection can improve significantly without upgrading your plan.

Why changing your router can improve your connection so much

The router provided by your internet provider is usually "locked down": certain advanced menus are blocked to prevent users from altering its settings . The intention isn't bad, but this also limits your ability to optimize your network, choose better DNS servers, manage channels, or adjust the transmission power.

Even so, even with the operator's equipment, it's worth entering the administration panel (usually 192.168.1.1 or 192.168.0.1) and tinkering with some key settings: band used, channel, DNS, firmware update, and security.

It's also important to understand that the contracted speed doesn't guarantee consistently smooth browsing: the remote server might be slow, networks could become congested, and your Wi-Fi could be plagued with interference. That's why both changing your router and configuring it correctly can make a significant difference in your daily experience.

Manually configure the router's DNS settings to improve speed

One of the most overlooked settings is the DNS (Domain Name System), the servers that "translate" website names into IP addresses . Every time you type a URL or click a link, your computer checks these DNS servers before the page starts loading.

Internet providers configure their routers with their own default DNS servers . They work, but they aren't always the fastest. If you choose faster servers, that slight resolution time is reduced, and the overall feeling is one of faster browsing, even if your maximum download speed remains the same.

A popular example is Cloudflare, which offers free DNS with very high performance and security . Many users prefer them even to Google's DNS or their own ISP's DNS because of their speed and responsiveness.

The addresses that are usually used are 1.1.1.1 as the primary DNS and 1.0.0.1 as the secondary . You can also opt for Google's DNS (8.8.8.8 and 8.8.4.4), but the idea is always the same: to find fast and reliable servers.

To change them from the router, the usual process is as follows (it may vary slightly depending on the model):

• Connect to WiFi or via cable and open the browser.
• Type in the address bar 192.168.1.1 or 192.168.0.1 (It is the most common gateway).
• Enter the username and password to access the router, which is usually on the sticker at the bottom of the device.
• Enter the section WAN, Internet or Advanced Settingsdepending on the interface.
• Find the DNS section and change the mode to “Static” or “Manual”.
• Enter 1.1.1.1 in the primary DNS and 1.0.0.1 in the secondary DNS, and save the changes.

Keep in mind that some internet service providers can remotely overwrite these settings , usually through a management system like TR-069 (found in the maintenance menu on many routers). If your device allows it, you can disable this remote management to prevent unauthorized changes.

However, it's important to clarify one thing: changing your DNS settings won't actually increase download or upload speeds in terms of maximum megabytes per second . What it does improve is the time it takes from when you click until the browser starts receiving data, which is very noticeable when browsing the web, searching, or using applications that make many small queries.

Router location: the site matters (a lot)

No matter how good your router is, if you hide it behind the TV, inside a piece of furniture, or in a far corner of the house , the signal will suffer. WiFi is radio, and any obstacle (walls, ceilings, doors, cabinets, metal structures) weakens the coverage and creates interference.

The best option is to place the router in a central location within your home , so that coverage is distributed more evenly. If you leave it at one end (for example, in the entrance or next to the ONT in the living room on one side of the house), the rooms furthest away will experience more frequent interruptions and slower speeds.

It also helps to place it at a certain height, on a table, shelf, or wall mount , never lying on the floor. Many routers distribute the signal in a way that improves coverage when the device is slightly elevated, without immediate obstructions.

Also avoid enclosing it: don't put it inside closets, false ceilings, or decorative boxes . Walls and doors reduce signal strength; the more open it is, the better coverage you'll have throughout the house.

You might be tempted to hide it because it's not exactly aesthetically pleasing, but if you cover it up too much, you'll end up paying the price with interruptions and a poor user experience. In large or multi-story homes, its location is even more critical, and you may need to combine it with other devices such as powerline adapters, repeaters, or mesh systems.

Position the antennas correctly to take advantage of the signal

Most routers with external antennas are shown in promotional photos with all the antennas pointing straight up, as if that were the "correct" position . However, that placement isn't always the most efficient for adequate coverage.

A very useful trick is to position the antennas perpendicular to each other: one vertically and the other horizontally . The technical reason is that reception is maximized when the device's antenna and the router's antenna share the same polarization plane.

In simpler terms: if your laptop, mobile phone, or console has its internal antennas facing a certain direction , it's best if at least one of the router's antennas also faces that direction to ensure a more stable connection and better signal.

Don't panic if they're all pointing upwards, it's not a big deal. Simply put, if you're looking to improve coverage a bit, especially in rooms that are a little further away, adjusting the antennas to a 90-degree angle can provide a small boost that will help along with the other adjustments.

You're not going to go from a disastrous connection to a perfect network just by turning the antennas, but in a more or less fine-tuned configuration, these details also matter.

Router firmware always up to date

Firmware is the internal software that controls all the router's functions . Manufacturers typically release regular updates to fix bugs, improve stability, patch security vulnerabilities, and even optimize Wi-Fi performance.

Some routers update automatically without the user having to do anything , while others require you to log into the administration panel and manually search for new versions.

It's advisable to check periodically for available firmware updates in your router's menu or on the manufacturer's website . Often, a simple update can reduce crashes, random disconnections, or compatibility issues with certain devices.

Furthermore, a recent firmware means more security against external attacks and known vulnerabilities , something fundamental in a device that is permanently connected to the Internet and exposed.

Choosing wisely between 2,4 GHz and 5 GHz WiFi

Modern routers typically offer at least two bands: 2,4 GHz and 5 GHz . Sometimes these appear as two separate networks (for example, "MyHome" and "MyHome_5G" or "PLUS"), and other times they are combined under a single name with automatic selection.

The 2,4 GHz band offers greater range and better penetration through walls , but it is slower and more susceptible to interference. It shares frequencies with many other devices (Bluetooth, microwaves, etc.) and also has fewer available channels, so it becomes easily congested in buildings with many residents.

In contrast, the 5 GHz band provides higher speed and is usually less congested , with more channels to distribute and better response for demanding activities such as online gaming, high-resolution streaming, or high-quality video calls.

The weakness of 5 GHz is that it has more difficulty penetrating walls and ceilings . In a large apartment or a multi-story house, the signal from that band might barely reach the furthest room, while the 2,4 GHz band handles the distance much better.

Therefore, the usual strategy is:

• Use 5 GHz for devices close to the router or connected by line of sight (desktop computers, consoles, Smart TVs next to the router).
• Use 2,4 GHz for mobile phones, tablets, or devices that are very far away, where the priority is to arrive with a stable signal, even if the maximum speed is lower.

A typical scenario: someone places their gaming PC on the third floor, and the router is in the basement, at the other end of the house. There, neither 5 GHz nor a poorly placed extender will work miracles : the speed plummets to less than 10 Mbps, and the connection drops constantly.

In situations like this, if you can't move the router because other family members need it for teleworking, it's essential to properly combine the band selection with other network devices (PLC, well-placed repeaters, Mesh) and, if possible, run a partial network cable to an intermediate point.

Choose the least congested WiFi channel

In addition to the band (2,4 or 5 GHz), each network operates on a specific channel within that band . If many nearby routers use the same channel, they interfere with each other, and performance plummets: increased latency, micro-cuts, reduced speeds, and an overall feeling of sluggish Wi-Fi.

At 2,4 GHz there are up to 14 possible channels (although not all are used in every country) , separated by only 5 MHz, while each channel requires a bandwidth of about 22 MHz. This causes many channels to overlap and generate interference.

That's why it's generally recommended to use channels 1, 6 and 11 in 2,4 GHz, as they are considered "non-overlapping" in practice: they maintain sufficient separation between them to minimize mutual interference.

There are significantly more channels in the 5 GHz band (between 24 and 25 depending on the country), and although saturation is usually lower, many home routers frequently use channels 36, 40, 44, and 48. This makes it easier to find a less noisy area.

Almost all routers have an automatic channel selection mode , which in theory chooses the least congested channel. The problem is that this analysis is performed periodically (for example, every 12 hours), and the actual situation can change significantly between times.

To fine-tune things, it's very useful to use apps like WiFi Analyzer, NetSpot, Fing, or others like it that let you see which channels your neighbors' networks use and which ones are less congested.

The procedure would be:

• Install a WiFi analysis app on your mobile phone or laptop.
• Identify your network and see which channel it's currently on..
• Check which nearby channels have fewer overlapping networks.
• Enter the router settings, go to WiFi and change the Control Channel from automatic to a specific, less saturated channel.

Ideally, run a speed and latency test before making any changes, and repeat it after switching channels. If the improvement isn't noticeable, try the next least congested option. With a little patience, you might see a clear improvement, especially in buildings with many networks nearby.

Optimize your connection: cable, network cards, and security

Beyond Wi-Fi, there are some basic points to ensure your home's overall connection works at peak performance . The first, though it may seem obvious, is to use an Ethernet cable for stationary devices whenever possible.

A wired connection is more stable, faster, and has better latency than any Wi-Fi, no matter how good the router is. If your PC, game console, or TV is near the router, it's best to connect them with a cable and use Wi-Fi for phones, tablets, and laptops.

The network card in your device also matters. If your PC or laptop has an older or lower-end Wi-Fi adapter, it can become a bottleneck and prevent you from taking full advantage of the speed offered by your router or fiber optic connection. Sometimes, investing in a good USB or PCIe Wi-Fi adapter significantly improves your experience.

Another critical aspect is network security . If your Wi-Fi has no password or you use a very simple one, anyone can connect and hog your bandwidth. Aside from the obvious security risks, this means slower speeds for you.

Make sure you use WPA2 or WPA3 encryption with a strong password and avoid passwords like 12345678 or similar. You can also see which devices are connected and disconnect any you don't recognize from your router's control panel.

What to do when WiFi doesn't reach: PLC, repeaters and Mesh networks

In many homes, especially those with multiple floors or large areas, no matter how well you position the router, the signal won't reach every room with sufficient quality . In these cases, in addition to experimenting with different bands and channels, it may be necessary to extend the network.

A very popular option is PLC (Powerline) . These devices use the home's electrical wiring to carry the connection from the router to another area where coverage is poor, creating a new WiFi access point there (and sometimes Ethernet ports as well).

Its setup is usually simple: you connect a PLC adapter next to the router and join it with a network cable , and place the second PLC in the room where you want to improve the signal, plugged into a direct power outlet (it's best to avoid power strips when possible).

Another option is traditional Wi-Fi repeaters , which are placed halfway between the router and the area with poor coverage. These capture the signal and amplify it to reach further. They work, but are usually less efficient than a good powerline adapter (PLC) and, in many cases, reduce the maximum speed by repeating the signal.

The third option, which is becoming increasingly common, is WiFi Mesh systems or mesh networks . These consist of several nodes that communicate with each other and with the router to offer a unified network, intelligently managing which point each device connects to.

The main advantage is that the nodes coordinate to determine which offers the best performance at any given time , not necessarily the one that is physically closest. This allows you to move around the house without losing signal or experiencing abrupt network changes, which is very convenient for mobile phones and laptops.

The downside is the price: Mesh systems are usually more expensive than a repeater or basic powerline adapters . But if you have a large house, many devices, and want stability, it can be one of the investments that makes the biggest difference in your daily life.

Managing saturation: fewer gadgets, better experience

In practice, we have more and more devices connected to the same router: mobile phones, tablets, laptops, consoles, televisions, home automation, smart speakers … All of this consumes a portion of the router's bandwidth and management capacity.

The more devices that are connected (especially if they are continuously transmitting data), the easier it is for the network to become overloaded . This results in slower speeds, increased latency, and a worse experience for gaming, video calls, or streaming.

It's a good idea to occasionally audit which devices are actually using the network and disconnect those you don't need. Many modern routers include parental control or QoS (Quality of Service) features that allow you to prioritize traffic from certain devices or applications.

For example, you can prioritize your home office PC or game console over other less critical devices, so that when there is congestion, you are not the one who suffers the outages.

If you have a very old or very basic router, it may not be able to handle a large number of devices well , even if your internet speed isn't exceptional. In those cases, upgrading to a more modern router with WiFi 5 (802.11ac) or WiFi 6 (802.11ax) can significantly improve stability and performance.

When is it worth upgrading to a better router?

While you can get a lot out of your ISP's equipment, there comes a point where the hardware itself sets the limit . If your router is old, crashes frequently, doesn't support modern bands, or doesn't offer WiFi 5/6, it's likely no longer meeting current demands.

When evaluating a new router, consider a few key aspects:

• WiFi Standard: at least WiFi 5 (802.11ac) and, if the budget allows, WiFi 6 (802.11ax).
• Gigabit Ethernet Ports: essential for taking advantage of fast wired fiber optic connections.
• Dual band or triband: to be able to separate devices between 2,4 GHz, 5 GHz and, in some models, 6 GHz.
• Number and type of antennasPowerful omnidirectional antennas help to better distribute the signal.
• Build quality and firmwareBrands with good support usually offer updates and greater stability.

If your internet provider has given you a very basic router, ask if they can send you a more modern model or, if you want more control, consider buying a third-party router and connecting it to the company's equipment in bridge mode or similar.

Investing in a good router, combined with careful configuration (fast DNS, well-chosen channels, good location, and up-to-date firmware), allows you to make the most of the connection you already pay for , without needing to upgrade to a more expensive plan just to mask coverage or saturation problems.

With all of the above, it's clear that improving your connection isn't just about getting more bandwidth, but about choosing a good router, positioning it correctly, adjusting bands and channels, configuring fast DNS, keeping the firmware updated, and supporting the network with PLC, repeaters, or Mesh when needed ; while also taking care of security and the number of connected devices, you can go from a frustrating WiFi to a stable, fast, and convenient connection throughout your home.
