Many residential buildings in Dillenburg's historic core have thick walls and electrics that have grown over decades; especially Wi-Fi coverage is often a real problem there. We find solutions that work without major structural interventions, for example with additional access points instead of complete re-cabling.
In newer residential areas around Dillenburg it is more often about home network, smart home devices or setting up new computers and printers. We explain clearly what we do instead of silently changing something.
