Question:

Could you provide guidance on resolving a network connectivity issue where a single device is unable to access the internet? This device, running Windows 11, successfully connects to the internet via a mobile hotspot but fails to do so when linked to the home modem either through Ethernet or Wi-Fi. Despite numerous troubleshooting steps, including driver updates, network resets, and standard command-line fixes, the problem persists. Notably, other devices in the home have no such issues. The modem and router are provided by the landlord, and the ISP, Bredbandsson, apparently offers free service. Any expert advice on this matter would be greatly appreciated.

Answer:

In the realm of home networking, it’s not uncommon for one device to stubbornly refuse internet access while others operate seamlessly. This conundrum can be particularly perplexing when the device in question connects without issue via alternative networks, such as a mobile hotspot. Let’s delve into potential solutions for a Windows 11 computer facing such a dilemma.

Initial Considerations

Firstly, it’s crucial to establish that the device’s hardware is functioning correctly. Since the computer can connect to a mobile hotspot, we can infer that the wireless adapter and Ethernet port are operational. Therefore, the issue likely lies within the network settings or the interaction between the device and the home network infrastructure.

Advanced Troubleshooting Steps

1.

Network Profile Reset

: Windows 11 allows users to reset network profiles, which can resolve conflicts between the device and the network. Navigate to Settings > Network & Internet > Advanced network settings > Network reset.

2.

Static IP Configuration

: Assigning a static IP address to the device can sometimes circumvent connectivity issues caused by dynamic IP assignment conflicts.

3.

Modem and Router Compatibility Check

: Ensure that the modem and router firmware is up-to-date and compatible with Windows 11. Outdated firmware can lead to connectivity problems.

4.

Alternate DNS Service

: Switching to a public DNS service like Google DNS or OpenDNS can resolve issues stemming from the ISP’s default DNS servers.

5.

Network Stack Rebuild

: Beyond the standard command-line fixes, consider using PowerShell to perform a deeper network stack rebuild. This process can rectify more complex network issues.

6.

ISP and Hardware Provider Consultation

: Since the modem and router are provided by the landlord and the ISP offers free service, it’s advisable to consult with them. They may have insights or restrictions specific to the network setup.

Conclusion

Persistent network issues can be frustrating, but by methodically working through these advanced steps, you can isolate and hopefully resolve the problem. If all else fails, seeking professional on-site assistance might be the most efficient path to a solution.
