Poor Wi−Fi signal (I live in an apartment)

If you live in an apartment (flat) your router's Wi-Fi signal might be weakened if too many routers are set to "broadcast" their Wi-Fi signal on the same channel. Most of the modern routers can broadcast on 11 channels, whereas some routers might broadcast on 13 channels.

In order to strengthen the Wi-Fi signal, you need to set the router to broadcast on a channel which is not used by many people. To identify such channels, install a wi-fi scanner, such as Acrylic Wlan Scanner (if you use Windows) and after you identify a channel as such, change your router's channel through the router's user interface.

* If you use Mac OS, run the Mac OS X – Wireless Diagnostics built-in utility.

A Wi-Fi range extender is a kind of wireless repeater used to expand the range of a Wi-Fi connection. It will cover all the gaps in your house or apartment and will improve your Wi-Fi signal.

Famous Wi-Fi range extenders include Netgear Nighthawk AC1900 Wi-Fi Range Extender (EX7000) and TP-Link AC1750 Wi-Fi Range Extender (RE450).

If you can't connect to the Internet and if your router is placed on the ground, lift it off the ground and place it in a higher location. Most routers are designed to broadcast the signal slightly downwards and the signal is not strong enough to penetrate some of the materials that make the floor, such as metal, concrete or cement.

If your router is far away from the wireless device (a laptop, smartphone, tablet, etc.), the signal will be weaker as it will be absorbed by the walls. Try placing the router as close as possible to the wireless device, if possible in the same room.

If the router's antenna is replaceable, i.e. if you can unscrew it and remove it, replace it with another one, which could share the Wi-Fi signal on a longer range. Make sure to buy an omnidirectional antenna, which shares the Wi-Fi in all directions.

This method has been proven to improve Wi-Fi reception and all you need is an empty beer can and scissors. See the video below to learn more details.

If you are using a router and you can't browse the net, you might be experiencing issues related to the quality and strength of your Wi-Fi signal. People usually place the router in a corner of their house/apartment and the signal that the router emits is being absorbed by the walls.

The closer you are to the router, the better.

There is an icon on the right corner of your taskbar (top right corner if you are a Mac user), which displays the strength of the Wi-Fi signal. If the bar is not full, try placing your router in a central location so that it will be in range (it will broadcast the signal in equal strength in all directions) of every device you use, and the signal will be stronger.

- Windows            - Mac OS

- Android            - iOS

Too many users connected to your router can weaken the Wi-Fi signal. If you haven't set up a password to the router, make sure to do it as soon as possible, because you might have uninvited guests connected to your router who make your wi-fi signal weaker and slow down your Internet.

In order to set a password to a router, you need to access your router's user interface, e.g. like in the video below:

If you are not sure how to access the user interface, see the don't know how to access my router guide.

Note: Make sure to set WPA2-PSK password, as it is almost impossible to decipher it.

Things like TV's, microwaves, computers, things that have a motor inside and other electronics can interfere with the router's signal, make it weaker and prevent your wi-fi capable devices from connecting to the internet.

Place your router away from other electronic devices and the signal should become stronger.

Note: If your router signal is still weaker, consider buying a stronger router.

If the Wi-Fi signal becomes extremely poor unexpectedly or it fluctuates all the time, even though you are within the router's range, try restarting your router. Unplug the router from the power outlet and plug it back in after 5 minutes.

Note: It is recommended that you perform this procedure at least once a month so that your router can empty its DNS cache and resync to the ISP (Internet Service Provider).

Some routers require occasional reboots to keep a healthy Wi-Fi signal and Internet connection. Some routers have a built-in option for a reboot as such in the router's user interface, but other routers do not.

In case if your router doesn't have an auto-reboot option, purchase an outlet timer and put your router in it.

Furniture items are known to absorb Wi-Fi signal and weaken it. If it is possible place furniture items along the exterior walls of your house or apartment, so that they won't absorb the Wi-Fi signal.

All metal surfaces are said to reflect Wi-Fi signals, including the thin metal layer found in most mirrors. Try reducing the number of mirrors around the router and other metal surfaces, as much as possible.

Perhaps your router needs an update. Router manufacturers are constantly working on improving the router's software and its performance.

Open the router's user interface and hit the Upgrade button.

Note: Before you do the upgrade, connect the router to the computer/laptop via an ethernet cable.
