Boost WiFi Signals On Concrete Walls

Do you have a dead spot in your house where the Wi-Fi signal can’t seem to reach? Are you struggling to get a good connection in your office because of the concrete walls?

If so, don’t worry – you’re not alone. Many people face this problem every day. In this blog post, we will discuss some methods that you can use to boost your Wi-Fi signals through concrete walls. Stay tuned!

Reason For Low Wi-Fi Signals

Wi-Fi signals can be easily blocked by physical objects such as walls, ceilings, and furniture. To get a better connection, try moving your router or any devices blocking it into another room.

If you have many Wi-Fi connections, they might become affected by external electronic devices employing the same radio frequencies, so try to move them away from each other. ( You May Also Like How to Connect a Landline Phone to a Wifi Modem or WiFi )

The most common weak Wi-Fi signals are because of distance. The farther you are from your router, it will be harder to get a strong signal strength.

In this case, if possible, try moving closer. Another factor affecting how well your signal travels through concrete walls is what type of material they’re made of. Concrete is a very dense material that will block most Wi-Fi signals.

There are, however, some methods that you can use to help boost your signal and get a better connection through those pesky concrete walls:

Use an Ethernet cable

This is the most reliable way to get a good connection through concrete walls.

An Ethernet cable will provide a direct connection between your router and your device, which is much better than relying on a Wi-Fi signal.

Install a Wi-Fi Extender

If you can’t or don’t want to use an Ethernet cable, installing a Wi-Fi extender might be the next best option.

A Wi-Fi extender will amplify the weak signal from your router and send it to where you need it.

Try Using a Directional Antenna

If neither of these options is viable for you, then try installing a directional antenna on top of the concrete wall or roof.

This will help boost your Wi-Fi signals through any obstruction like furniture, ceilings, etcetera. You can also use multiple antennas to create a stronger signal.

Try Changing The Frequency Of The Router

If you’ve tried all of these methods and still can’t seem to get a good connection, then try changing the frequency of your router.

Some routers have multiple frequencies that you can choose from, so try switching to a different one until you find one that works best for you.

Update Your Router’s Firmware:

If you’ve tried all of these methods and still can’t seem to get a good connection, then try updating your router’s firmware. Updating your router’s firmware can sometimes help improve the Wi-Fi signal strength. ( Read Also How To SetUp Opticover WiFi Extender? )

Use Omni-Directional Antenna

The omnidirectional antenna is a great way to improve your Wi-Fi signal through walls. This cheap and simple solution has been one of those things you probably haven’t tried yet because it’s so easy, but now it may be worth looking into for those having trouble with their connection!

Just attach an additional cable from the back of your router up through any opening to reach places not covered by other parts of networks, then place this little guy on top. It’ll broadcast its goodness all around like never before, helping give range where needed most.

Connections On Router

The more people on your Wi-Fi connection slow down the internet connection overall.

Well, imagine if all these devices were vying for signal. That’s why it’s essential not to stream videos or play online games while seeking an excellent connection with your computer!

Furthermore, too many users accessing web-based content at one time can reduce speed for each user as well, so try using different times of day to see what happens then too.

Try Using Reflector For Your Router

If you notice that concrete walls weaken your Wi-Fi signal, try using a reflector. There are many different types of things that can be used as Reflectors, but we recommend aluminum foil or an old tin stuck onto the wall.

Hence, it faces towards where the router resides, and this will help signals to bounce back making them stronger rather than weak like before when they were getting eaten up quickly by too much absorption by these types of terrain objects.

You may also want to invest in reflectors with more precise specifications, such as parabolic dish-shaped models if needed!

Powerline Adapter

When you need to get an internet connection in another room of your house, a powerline adapter can provide this with ease. It will take the Ethernet cable from being plugged into one end and convert it into electrical signals to carry them through walls!

This type provides faster speed than using network extenders because there isn’t any extra hardware needed – just set up port forwarding on routers for each device needing online access.

A home’s size doesn’t matter; they work great anywhere inside, even whole buildings (depending upon how many rooms share similar plumbing).

Upgrade Your Router

We’ve covered a few of the most common problems that cause Wi-Fi signals to drop.

if still the issue has not been resolved. You should check your router. If you aren’t getting enough internet speed from it, then there may be an issue with distance or coverage area for whatever reason. May it is because another device blocks part way downrange on their spectrum channel split?

In either case, we at Tech Lexa recommend upgrading, so as long as signal strength hasn’t failed at this point (which would mean age), consider buying something new instead! You can find great routers priced under $100 nowadays; usually, they come equipped with several year’s warranty too.

Purchase a Wi-Fi Amplifier

Wi-Fi amplifiers can be a great option for overcoming signal problem in large homes or interference from other devices. They will help boost the signal your router sends out, allowing you to get speed back up again!

These are just some of the many methods that you can use to boost your Wi-Fi signals through concrete walls. Hopefully, one of these methods will work for you and help improve your connection. Thanks for reading!
