Corrections

Found a wrong specification, a price that is way off, or a measured speed we should add? Please include:

• the switch (and its hardware version, if you know it),
• what is wrong and, if possible, a link to the source (manufacturer page, review, datasheet).

We review every correction and update the page with a new “last reviewed” date.

Suggestions

Suggest switches worth adding. We prioritise small models you can actually buy on Amazon in the US or Spain.

What we cannot do

We cannot provide one-to-one support for setting up your network. Our guides cover the most common questions.

Manufacturers and retailers: we do not accept payment for reviews or rankings. See our affiliate disclosure.
