Few things are more annoying than a video call freezing mid-sentence or a movie buffering right at the best part. If your home Wi-Fi feels slower than it should, the good news is that most speed problems have simple fixes you can do yourself in a few minutes. This Asandada24 guide walks you through the most effective ways to improve Wi-Fi speed at home, starting with the easiest ones.
Why Is Your Wi-Fi Slow in the First Place?
Before changing anything, it helps to understand what usually causes slow Wi-Fi. In most homes, the problem is not the internet plan itself. At Asandada24, we tested dozens of home networks and found that the same handful of issues comes up again and again.
The most common causes are a router placed in a bad spot, too many devices connected at once, interference from neighbours’ networks, outdated router firmware, or simply an old router that can’t keep up with modern speeds. Sometimes the issue is on your internet provider’s side, but that is actually less common than people think.
A quick way to check: run a speed test on your phone while standing next to the router, then run it again in the room where the Wi-Fi feels slow. If the speed drops a lot between the two spots, the problem is your home network, not your provider. Our guide on how to check internet speed on a mobile phone shows you exactly how to do this test properly.
Restart Your Router (Yes, Really)
It sounds too simple, but restarting your router fixes slow Wi-Fi more often than any other single step. Routers are small computers, and like any computer, they get sluggish when they run for weeks without a break. Memory fills up, connections pile up, and performance drops.
Unplug your router from the power socket, wait a full 30 seconds, then plug it back in. Give it two or three minutes to fully restart and reconnect. Then test your speed again. This Asandada24 guide recommends doing this once a month as basic maintenance, even when everything seems fine.
If your router has a separate modem (the box your internet provider gave you), restart that too — unplug both, plug the modem back in first, wait for its lights to stabilise, then plug in the router.
Move Your Router to a Better Spot
Where your router sits makes a huge difference. Wi-Fi signals spread out in all directions and get weaker as they pass through walls, floors, and furniture. A router stuffed in a corner of the house, behind the TV, or inside a cabinet is fighting with one hand tied behind its back.
The best spot for a router is:
- Central — as close to the middle of your home as possible, so the signal reaches every room evenly.
- Elevated — on a shelf or table, not on the floor. Wi-Fi signals spread slightly downward, so height helps.
- Open — out in the open, not hidden inside a cupboard or behind large metal objects like fridges.
- Away from interference — keep it a metre or two away from microwaves, baby monitors, and Bluetooth speakers, which can interfere with the signal.
If your internet connection point (the wall socket) is in a bad corner, consider using a longer cable to move the router somewhere more central. A small change in position can sometimes double your speed in distant rooms.
Switch Between 2.4 GHz and 5 GHz Bands
Most modern routers broadcast two Wi-Fi networks: one on the 2.4 GHz band and one on the 5 GHz band. Many people connect to whichever one appears first and never think about it again, but choosing the right one matters.
2.4 GHz travels further and passes through walls better, but it is slower and more crowded. 5 GHz is much faster but has a shorter range. So the rule of thumb is simple: use 5 GHz when you are in the same room as the router (or close by), and use 2.4 GHz when you are further away.
If your router combines both bands under one network name, check its settings app for a “band steering” or “smart connect” option — this lets the router automatically put each device on the best band. If you can see two separate network names (often one ends in “_5G”), try both and see which is faster in each room.
This is also worth knowing when you compare connection types. Our article on Wi-Fi vs mobile data explains when each one is the better choice.
Update Your Router’s Firmware
Router manufacturers regularly release firmware updates that fix bugs, close security holes, and sometimes improve performance. Many people never update their router, which means they miss out on these improvements.
How you update depends on your router. Many newer routers update automatically, or let you do it from a phone app (check the manufacturer’s app on your phone). For older routers, you log in to the router’s admin page through a web browser — usually at an address like 192.168.1.1 — and look for a firmware update option.
If you are not sure where to start, the manufacturer’s support site will have step-by-step instructions. Google’s own help centre at support.google.com has clear guides for Google Wifi and Nest Wifi devices, and most other brands have similar pages.
Set a reminder to check for firmware updates every few months. It takes five minutes and keeps your network running smoothly and securely.
Change the Wi-Fi Channel
Wi-Fi networks in the same area share the airwaves, and if your neighbours’ routers are using the same channel as yours, they interfere with each other. This is very common in apartment buildings where dozens of networks overlap.
On the 2.4 GHz band, channels 1, 6, and 11 are the only ones that don’t overlap with each other, so one of these three is usually the best pick. On the 5 GHz band there are many more channels and interference is less of a problem.
Some routers pick the best channel automatically — look for an “auto channel” setting and turn it on if it isn’t already. If your router lets you choose manually, there are free Wi-Fi analyser apps for Android that show you which channels are crowded around you, so you can pick a quieter one. Android’s official site at android.com lists the latest features available on current phones, including built-in network tools.
Reduce the Load: Too Many Devices
Every device connected to your Wi-Fi uses a share of its capacity. A typical home today might have phones, tablets, laptops, a smart TV, a game console, smart speakers, and security cameras all connected at once. When too many of them are active simultaneously, everything slows down.
You don’t need to disconnect everything, but a few smart moves help:
- Pause what you’re not using. A smart TV streaming in 4K in an empty room is eating bandwidth for nothing.
- Schedule big downloads. Set game consoles and computers to download updates overnight instead of during the day.
- Use Quality of Service (QoS). Many routers have a QoS setting that lets you prioritise certain devices or activities, like giving your work laptop priority over a background download. Check your router’s app or admin page.
- Consider a guest network for smart home gadgets. Putting smart bulbs and plugs on a separate guest network keeps them from competing with your main devices.
If slowdowns happen mostly on your phone when you’re away from Wi-Fi, the issue might be your mobile connection instead. Asandada24 recommends checking our guide on how to fix mobile internet not working on Android in that case.
Upgrade Old Equipment
Sometimes the honest answer is that your router is just too old. If your router is more than five or six years old, it probably uses older Wi-Fi standards that cap your speed no matter what plan you pay for. A Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax) router makes a noticeable difference.
You don’t need the most expensive model. A solid mid-range router from a reputable brand is enough for most homes. Look for:
- Support for Wi-Fi 5 or Wi-Fi 6
- Dual-band (2.4 GHz + 5 GHz) at minimum
- Enough range for your home size — for large homes, consider a mesh Wi-Fi system with two or three units
Also check the cables. If your router connects to the modem with an old, damaged Ethernet cable, replace it — a cheap Cat5e or Cat6 cable is all you need.
Secure Your Network
An unsecured or weakly secured Wi-Fi network can be slowed down by freeloaders — neighbours or passers-by using your connection without you knowing. Even if no one is stealing your Wi-Fi, weak security settings can limit your speed.
Make sure your network uses WPA2 or WPA3 security (not the old, broken WEP). Use a strong password that isn’t the default one printed on the router. And change the router’s admin password too — many people never change it from “admin/admin”, which is a security risk.
While you’re at it, check the list of connected devices in your router’s app. If you see devices you don’t recognise, change your Wi-Fi password immediately.
When to Call Your Internet Provider
If you’ve tried everything above and your speed is still far below what you’re paying for — even when standing right next to the router — the problem is probably with your provider or the line coming into your home. Before calling, run a speed test with a device connected directly to the modem with a cable, so you can tell them the exact numbers.
Note the difference between speed and connectivity: if pages won’t load at all, that’s a different problem from slow loading. For laptop-specific connection troubles, see our guide on how to connect a laptop to Wi-Fi and fix common problems.
Frequently Asked Questions
Why is my Wi-Fi slow only in certain rooms?
This is almost always a range or obstacle problem. The signal weakens with distance and when passing through walls — especially concrete or brick. Moving the router to a more central spot, or adding a Wi-Fi extender or mesh node, usually fixes it.
Does having more devices slow down Wi-Fi?
Yes. Every connected device shares the router’s capacity. The slowdown is most noticeable when several devices stream video or download large files at the same time. Using QoS settings or scheduling heavy downloads for off-peak hours helps.
Will a VPN slow down my Wi-Fi?
A VPN can slightly reduce your speed because your data takes a longer route and gets encrypted. If you use one and notice a big drop, try a different server location. You can learn more in our explainer on what a VPN is and how it works.
How often should I restart my router?
Once a month is a good habit, even if everything seems fine. It clears temporary glitches and keeps performance steady. Some newer routers can be scheduled to restart automatically overnight.
