Why your wireless speed drops and what you can do about it
Wireless internet slows down for three main reasons: your router is too far away or blocked by walls, too many devices are connected at once, or your router is using an older standard. You can fix most of these without calling your internet provider. The fastest improvement usually comes from moving your router to a central location, switching to the 5 GHz band if your devices support it, or reducing interference from other electronics.
Your wireless speed is never as fast as your wired speed, even with a perfect setup. Wireless signals weaken over distance and through obstacles. But you can get close to your plan's advertised speed if your router is positioned well and not overloaded.
Key Takeaways
- Move your router to a central, elevated location away from walls, metal objects, and devices like microwaves and cordless phones that cause interference.
- Switch devices to the 5 GHz band instead of 2.4 GHz if they support it — 5 GHz is faster but has shorter range.
- Restart your router every few weeks by unplugging it for 30 seconds, which clears its memory and can restore speed.
- Reduce the number of devices actively using the network, especially those streaming video or downloading large files.
- Update your router's firmware through its settings page, which patches performance problems and security issues.
Move your router to the right spot
Router placement is the single biggest factor in wireless speed. A router in a closet, basement, or corner of your home will deliver weak signal to most rooms. The best location is central and elevated — a shelf or wall mount in a hallway or living room, not hidden behind furniture or inside a cabinet.
Keep your router away from metal objects, which block wireless signals. Refrigerators, filing cabinets, and metal shelving all weaken the signal. Microwaves, cordless phones, baby monitors, and Bluetooth speakers also interfere because they use the same 2.4 GHz frequency as older wireless devices. If you have a choice, place your router at least six feet away from these devices.
Walls and floors slow the signal too, but you cannot avoid them entirely. Each wall between your router and device costs you speed. If you have a two-story home, putting the router on the first floor in a central location reaches both floors better than putting it upstairs in a corner.
Use the 5 GHz band for faster speeds
Most modern routers broadcast on two frequencies: 2.4 GHz and 5 GHz. The 2.4 GHz band is older, slower, and more crowded because older devices and appliances use it. The 5 GHz band is faster but does not travel as far and cannot pass through walls as easily.
If your device supports 5 GHz — most phones, laptops, and tablets made in the last five years do — switch to it. You will see two network names in your wireless list, often something like "YourNetwork" and "YourNetwork-5G". Connect to the 5G version. You will get faster speeds as long as you are in the same room as the router or one room away.
Devices that do not support 5 GHz, like older smart home devices or budget tablets, will stay on 2.4 GHz. That is fine — they will not slow down your 5 GHz devices because the bands are separate.
Restart your router regularly
Routers are small computers that run continuously. Over time, their memory fills up and they slow down, similar to how a laptop gets sluggish after weeks without a restart. Restarting clears this buildup and often restores speed.
Unplug your router's power cable, wait 30 seconds, and plug it back in. Wait two to three minutes for it to fully restart — you will see lights on the front stop blinking and settle into a steady pattern. Do this once every two to four weeks, or whenever you notice speed dropping.
If you have a modem (a separate box from your router), restart that too. Unplug the modem first, then the router. Wait 30 seconds, plug the modem back in, wait for it to fully restart, then plug in the router.
Reduce the number of devices using the network
Every device connected to your router shares the available bandwidth. If one person is streaming 4K video while another is downloading a large file and a third is in a video call, the network is divided three ways. Each person gets slower speeds.
Check how many devices are actually connected. Log into your router's settings page — usually by typing 192.168.1.1 into a web browser, though the exact address is on a sticker on the back of your router. Look for a section called "Connected Devices" or "DHCP Clients". You may find devices you forgot about: old phones, tablets, smart home devices, or guest devices.
Disconnect devices you are not using. Remove old phones and tablets from the network. If you have smart home devices like cameras or speakers that are not in use, disconnect them temporarily. The fewer active devices, the more bandwidth each one gets.
Update your router's firmware
Firmware is the software that runs your router. Manufacturers release updates to fix performance problems, improve range, and patch security issues. Many routers check for updates automatically, but some require you to do it manually.
Log into your router's settings page and look for a section called "Administration", "System", "Maintenance", or "Firmware Update". If an update is available, install it. The router will restart during the update — this takes a few minutes and your internet will go down briefly.
If your router is more than five years old, check the manufacturer's website to see if it is still receiving updates. Older routers eventually stop getting updates, which is one reason to consider replacing them.
Change your wireless channel if you have interference
Wireless networks use channels, similar to radio stations. If your neighbors' routers are on the same channel as yours, they interfere with each other and slow you down. This is most common in apartments or dense neighborhoods.
Log into your router's settings and look for "Wireless Channel" or "Channel Selection". On 2.4 GHz, use channel 1, 6, or 11 — these do not overlap with each other. On 5 GHz, there are many more channels and overlap is less common. Some routers have an "Auto" setting that picks the best channel automatically.
If you want to check which channels your neighbors are using, read a free app like WiFi Analyzer on Android or iStumbler on Mac. It shows nearby networks and their channels. Pick a channel that has fewer neighbors on it.
When to replace your router
If you have tried these steps and your wireless speed is still much slower than your wired speed, your router may be too old. Routers older than five years often use slower wireless standards and do not support newer features like 5 GHz or the latest security protocols.
Check your router's model number — it is on a sticker on the back — and search for its specifications online. If it only supports 802.11n or older, it is outdated. Modern routers support 802.11ac or 802.11ax (WiFi 6), which are significantly faster.
A new router in the $50 to $150 range will handle most homes. If you have a large home or many devices, spend more for better range and performance. Mesh routers, which use multiple units to cover your whole home, are worth considering if your current router cannot reach all rooms.
Frequently Asked Questions
How far should my router be from my device?
Ideally within 30 feet on the same floor, or one floor away. The farther you are, the slower your speed. Walls and metal objects reduce range further. If you need coverage in distant rooms, consider a mesh router system or a second access point.
Will a new router make my internet faster if my plan is slow?
No. A router cannot make your plan faster — it can only deliver the speed your provider gives you. If your plan is 25 Mbps, a new router will help you reach that speed consistently, but not exceed it. Check your actual speed with a speed test to see if your router is the problem.
Is 2.4 GHz or 5 GHz better for gaming?
5 GHz is better for gaming because it is faster and has lower latency, meaning less delay between your actions and the game's response. Use 5 GHz if your device and router support it, and keep your device close to the router to maintain a strong signal.
Can I use both 2.4 GHz and 5 GHz at the same time?
Yes. Most modern routers broadcast both bands simultaneously. Devices that support 5 GHz can connect to it while older devices use 2.4 GHz. They do not interfere with each other because they use different frequencies.
What is the difference between a router and a modem?
A modem connects your home to your internet provider's network. A router takes that connection and broadcasts it wirelessly to your devices. Many homes have both as separate boxes, though some providers offer a combined modem-router unit.
