Question:

How to troubleshoot network connectivity issues on multiple devices with different interfaces?

I have been experiencing network connectivity issues on my PC, Xbox, and TV for the past few days. My PC has no internet connection via Ethernet or WiFi, while my phone can connect to WiFi. My Xbox and TV have intermittent connection via Ethernet, with slow speeds and frequent buffering. I have tried various steps to fix the problem, such as resetting the router, renewing the IP address, flushing the DNS cache, and changing the cables and sockets, but none of them worked. I have attached the output of ipconfig /all from my PC for reference.

What could be the cause of this problem and how can I resolve it?

Thank you for your assistance.

Answer:

Network connectivity issues can be frustrating and difficult to diagnose, especially when they affect multiple devices with different interfaces. In this article, we will explore some possible causes and solutions for the problem described by the user.

Possible causes

There are many factors that can affect network connectivity, such as hardware, software, configuration, and external interference. Some of the possible causes for the user’s problem are:

• Faulty router: The router is the device that connects the user’s local network to the internet. If the router is malfunctioning, it can cause problems with assigning IP addresses, routing traffic, and providing wireless signals. A faulty router can also affect the performance and stability of the network.
• Incorrect settings: The settings on the user’s devices and router can also affect network connectivity. For example, if the user’s devices have static IP addresses that conflict with the router’s DHCP range, or if the router’s firewall or security features are blocking certain ports or protocols, it can cause connectivity issues.
• Damaged cables or sockets: The physical connections between the user’s devices and router can also be a source of network problems. If the cables or sockets are damaged, loose, or dirty, they can interfere with the signal quality and cause packet loss, latency, or disconnection.
• Wireless interference: Wireless signals can be affected by various sources of interference, such as other wireless devices, appliances, walls, or metal objects. Interference can reduce the signal strength and quality, and cause slow speeds, buffering, or disconnection.
