We live in a house, in the village, we have good internet but the old router could not cope. I researched and discovered the TP-Link Mesh Wi-Fi System with its Seamless Roaming, Adaptive Path and Self Healing functions. I chose a Deco S4 AC1200 Whole Home Mesh Wi-Fi System with full coverage for the whole house because I wanted a Gigabit router for higher speeds and I needed at least 3 units because we use the internet upstairs, downstairs, everywhere.
