Wireless signal strength

Wireless signal strength: How to know if your device is getting the best connection?


Have you ever been annoyed by poor wireless signal strength while surfing the internet or trying to download something? Who hasn’t, right? Luckily, there are ways to ensure that your device is getting the best connection possible.
Firstly, make sure your device is in a clear and direct line of sight to the router. Avoid obstructions, such as walls or metal objects, as they can interfere with the signals. Additionally, keeping your router away from other electronic devices can prevent interference and boost your signal strength.
If you’re still experiencing weak signals, it may be time to check your router’s settings. Try adjusting the antenna or even upgrading to a router with a stronger signal. You can also consider purchasing a range extender or booster to amplify the signal strength.
Another option is to check for software updates on your device or router. Manufacturers often release updates to improve signal strength and overall performance.
Lastly, keep in mind that the distance between your device and the router affects the signal strength. Moving closer to the router or installing a mesh network system can improve your connection.
Now that you know how to boost your wireless signal strength, say goodbye to buffering and slow downloads. You’ll be streaming your favorite shows in no time!

Are all the ports on your router open? If you don't know the answer to that question, then you could potentially be putting your home network at risk.


What are Open Ports?


Router ports are like doors on a house. They allow data to enter and exit your home network. An open port is a port that is accepting incoming data from the internet. This can be a security risk because it provides a direct access point for anyone who wants to try and breach your network.


How can you check?


You can check which ports are open on your router by accessing the router's administrative interface. This interface will differ depending on the model and brand of router you have, but generally, you can access it by typing your router's IP address into a web browser. Once you're in, you can look for the option to view the router's port forwarding settings.


Why it's important?


Keeping all of your ports open is an unnecessary risk. It's important to only open the ports that are absolutely necessary for the applications or services you use. By closing unused ports, you can greatly reduce the risk of a security breach.


Don't wait until you've already been hacked to start being proactive about your network security. Take a few minutes to check which ports are open on your router, and close any that are unnecessary. Your personal information and all of your network-connected devices will thank you.
