If you are looking for an easy way to have WiFi-coverage in your entire house, mesh is definitely a solution you should consider. Without having to drill in the walls you can easily build a network that covers the entire house. The secret of mesh are the nodes, of which one serves as router and the others as send- and receive stations, allowing the system to spread the network through your entire house.
As with the Linksys Velop-system, the TP-Link Deco M5 uses this technique. However, at an average price of 240 pounds / 269 euros for a set of three nodes the latter is a lot less expensive. The system is set up more straightforward, because there are no separate radios to realize the connection between the nodes. Thanks to the usb-c connector it is possible to utilize powerline as backbone in the future.
Despite this, Deco manages to perform well in terms of speed; under the same circumstances we measured a throughput nearly twice as much as the more expensive Linksys Velop-system. A point of criticism is that Deco, as Velop, can only be managed through the use of an app that has limiting possibilities at the time of writing. For example, during the testing port forwarding and multi-language support were missing. These are rough edges although, according to TP-Link, they will be added in the future. Nevertheless we are positively surprised by the performance and fucntioning of the Deco set. The price makes it accessible for those on a tighter budget. As long as you do not continuously burden the radios, this set is more than enough. Therefore, a Great Value award is more than appropriate.
