Networking Signal is an independent networking publication. We explain how networks actually work, why they break, and what to buy when you need to fix or build one. No jargon for its own sake, no filler, and no recommendation we would not follow ourselves.
Who writes here
The site is written and run by two brothers.
Jaspreet Singh founded Networking Signal and writes most of the routing, switching and troubleshooting material. His interest is in the layer where theory meets a live network: why a spanning tree topology converges the way it does, why a link negotiates at the wrong speed, why a route that looks correct in the table is never used.
Gurpreet Singh covers wireless, security and the home and small office side of the site. He handles most of the hardware guides, which means he is the one working out whether a router that costs three times as much is actually three times better.
Between us we have spent years working with the equipment we write about. Where an article describes a command, a configuration or a measurement, it is because we have run it.
The website itself is built and maintained by Logical Dottech, a web development team in Haryana, India.
What we publish
Networking Signal has been publishing since 2020 and the archive now holds more than 440 articles. They fall into four groups.
- Explainers. What a protocol is, how it works and where it fits. BGP, OSPF, spanning tree, DHCP, NAT, VLANs, the OSI model and the rest of the fundamentals.
- Troubleshooting guides. A symptom you can search for, then an ordered set of checks that stop at the first real failure. WiFi connected but no internet, a red LOS light, a self assigned IP address, an Ethernet port that refuses to come up.
- Buying guides and comparisons. Cat6 against Cat6a, mesh against an extender, one router against another. We explain the trade off before we name a product.
- Free tools. A growing set of browser based calculators including a subnet calculator, a CIDR to subnet mask converter, a VLAN calculator, a PoE power budget planner and an OSI model quiz. They are all on the free networking tools page, they all run entirely in your browser, and none of them ask for an email address.
How we work
Three rules govern everything on the site.
We test before we publish. Commands are run, configurations are applied and numbers are measured or taken from the vendor documentation, which we cite. When something is a rule of thumb rather than a measurement, we say so.
We correct mistakes in public. Networking changes and so do we. When an article is wrong we fix it and note the change rather than quietly editing it away. If you spot an error, tell us and we will act on it.
Money never buys a recommendation. We earn from display advertising and from affiliate commissions when a reader buys through our links. No manufacturer pays for coverage, for a review, or for a position in a list. If a product is the wrong choice we say so, including when we would earn a commission on it. This is set out in full in our editorial policy and our affiliate disclosure.
Who this site is for
Students working towards a networking certification, technicians who need an answer during a callout, IT staff running a small or medium network, and anyone at home who wants to understand what their router is doing instead of just rebooting it. The explainers assume no prior knowledge. The deeper material assumes you can read a configuration.
