Why Your Wifi Is Not Working Properly: Common Problems and How to Solve Them


What could be the cause of intermittent wifi connection despite high speed and ethernet cable?

I have been experiencing random wifi dropouts for about 18 months, regardless of the number of devices connected or the time of day. My wifi router is an ARRIS Surfboard SBG10, which supports 13 devices, including smart TVs, phones, home security, Alexa, and a PS5. I have tried changing router settings, disconnecting devices, and using an ethernet cable, but none of these solutions have worked. The ethernet cable improved my download and upload speed, but I still get lagged out of games and parties on my PS5. The problem seems to have started after I got Alexa a few months ago. I recently discovered that a wireless printer near the router was causing interference, and turning it off solved the issue. However, I am not sure if this is the only factor or if there are other possible causes. I am not very tech-savvy, but I would appreciate any expert advice on this matter. Thank you for your help.


Wifi is a wireless technology that allows devices to connect to the internet without cables. However, wifi signals can be affected by various factors, such as distance, interference, congestion, and router settings. In this article, we will explore some of the possible causes of intermittent wifi connection, and how to troubleshoot them.


One of the most common causes of wifi problems is the distance between the device and the router. Wifi signals can weaken as they travel through walls, floors, and other obstacles. The farther the device is from the router, the weaker the signal will be, and the more likely it will drop out. To improve the wifi connection, try to place the router in a central location, and avoid placing it near metal objects, mirrors, or appliances that can block or reflect the signals. You can also use a wifi extender or a mesh network to boost the wifi coverage in your home.


Another cause of wifi issues is interference from other wireless devices or networks. Wifi signals use radio frequencies to communicate, but these frequencies can be shared by other devices, such as cordless phones, microwaves, Bluetooth speakers, baby monitors, and wireless printers. These devices can create noise or interference that can disrupt the wifi signals. Similarly, if there are many wifi networks in your area, they can compete for the same frequencies and cause congestion. To reduce the interference, try to change the wifi channel on your router, or use a dual-band router that can operate on both 2.4 GHz and 5 GHz frequencies. The 5 GHz band is less crowded and faster than the 2.4 GHz band, but it has a shorter range and can be more easily blocked by walls. You can also turn off or move away any devices that can interfere with the wifi signals, such as the wireless printer that you mentioned.

Router settings

Another possible cause of wifi problems is the router settings. The router is the device that connects your wifi network to the internet, and it has various settings that can affect the wifi performance. For example, the router’s firmware is the software that controls its functions, and it may need to be updated regularly to fix bugs or improve security. The router’s security settings can also affect the wifi connection, as some devices may not be compatible with certain encryption methods or passwords. The router’s QoS (Quality of Service) settings can also affect the wifi speed, as they can prioritize certain types of traffic over others, such as gaming or streaming. To check and change the router settings, you need to access the router’s web interface, which usually requires entering the router’s IP address, username, and password in a web browser. You can find these information on the router’s label, manual, or website. You can also contact your internet service provider or the router manufacturer for assistance.

Ethernet cable

You mentioned that you used an ethernet cable to connect your PS5 to the router, but you still experienced lag and dropouts. This suggests that the problem may not be related to the wifi, but to the internet connection itself. The ethernet cable is a wired connection that can provide faster and more stable internet than wifi, but it can also have issues, such as damage, loose connection, or compatibility. To troubleshoot the ethernet cable, you can try to replace it with another one, make sure it is securely plugged in, and check if it supports the speed and standard of your router and device. You can also test the internet speed and latency using online tools, such as speedtest.net or pingtest.net, and compare the results with your internet plan. If the results are significantly lower than expected, you may need to contact your internet service provider or the router manufacturer for support.


In conclusion, there are many possible causes of intermittent wifi connection, such as distance, interference, router settings, and ethernet cable. To troubleshoot them, you can try to improve the wifi signal strength and quality, change the wifi channel or band, update the router firmware and settings, and check the ethernet cable and internet speed. If none of these solutions work, you may need to seek professional help from your internet service provider or the router manufacturer. We hope this article has been helpful, and we wish you a smooth and stable wifi connection.
