About this tag
Windows networking covers the practical side of connecting Windows PCs to local networks and the internet, from wired Ethernet and Wi-Fi to SMB file sharing and DNS. Common threads include troubleshooting errors like 0x80070035, ERR_CONNECTION_RESET, and DNS_PROBE_FINISHED_NXDOMAIN, as well as configuring adapter metrics to prefer Ethernet over Wi-Fi. The tag also touches on hardware like USB 10GbE adapters, IPv6 privacy considerations, and Windows-adjacent infrastructure issues such as dnsmasq vulnerabilities that can disrupt name resolution. Content is practical and focused on fixes, settings, and understanding how Windows networking behaves in real-world scenarios.

    0x80070035 Fix: Test Windows SMB, DNS and Port 445

    Error 0x80070035, “The network path was not found,” means Windows failed before it could open the shared folder you requested. The practical fix is not to start by remapping the drive or enabling every legacy sharing option: first determine whether the failure is name resolution, basic IP...

    Windows Wi-Fi: Test 80 MHz on 5 GHz, Keep 2.4 GHz at 20 MHz

    MakeUseOf’s test of changing a home router’s 5 GHz channel width from 20 MHz to 80 MHz produced a real, if highly variable, throughput increase: reported download results rose from roughly 85–100 Mbps to a range of 125–300 Mbps, with occasional results above 325 Mbps. For a Windows PC connected...

    Asus ROG USB-C10G Needs USB 20Gbps for Full 10GbE Speeds

    Asus has put the ROG USB-C10G on its global product pages: a 38-gram USB adapter with an RJ45 port rated for 10Gbps Ethernet and a USB 3.2 Gen 2x2 host connection. The practical catch is in the interface requirement. It is only a full 10GbE upgrade when the host can supply a 20Gbps USB-C...

    ERR_CONNECTION_RESET: Fix Chrome, Edge and Windows Network Resets

    ERR_CONNECTION_RESET is one of the more confusing browser errors because it looks like a website failure, yet the actual cause may sit anywhere between the browser, Windows networking stack, router, VPN, security software, ISP, or the website’s own server. In plain terms, the browser began...

    Fix DNS_PROBE_FINISHED_NXDOMAIN in Chrome on Windows

    Chrome’s “DNS address could not be found” message—often paired with DNS_PROBE_FINISHED_NXDOMAIN—means the browser could not translate a site name such as example.com into an IP address. If one site fails while unrelated sites open normally, the domain or URL is probably the problem. If several...

    RFC 8981 Cuts IPv6 Temporary Address Lifetime to 2 Days

    IPv6 can expose more durable network identifiers than many users expect because early EUI-64 addressing embedded a device’s MAC-derived fingerprint, household prefixes may remain stable, and poorly designed VPN or router configurations can let IPv6 traffic bypass privacy assumptions even on...

    Prefer Ethernet Over Wi‑Fi on Windows 10/11: Set Interface Metrics (IPv4/IPv6)

    Windows still lets users give Ethernet priority over Wi-Fi by lowering the wired adapter’s interface metric, with the most reliable modern method on Windows 10 and Windows 11 being a manual metric change through adapter properties or PowerShell. The old adapter-order trick survives mostly as a...

    Windows Network Discovery Prompt Goes Public on a Stratford Billboard

    Windows has managed to do what decades of marketing could not: turn a routine networking prompt into a public spectacle on a giant billboard outside Stratford station. The image of a PC asking whether it should be discoverable is funny on its face, but the real story is broader than a stray...

    Fix Remote Desktop Lag: Disable Nagle and Delayed ACK with TcpNoDelay

    The subtle lag some Windows users blame on their ISP is often something far more mundane: a TCP behavior that favors efficiency over immediacy, and in the wrong workflow, that trade-off can feel like broken responsiveness. In remote desktop sessions, SSH shells, and other chatty TCP-based tasks...
