Mesh Wi-Fi kits have been picking up in popularity, and many people with large spaces to cover have turned to multi-node systems in order to create a seamless blanket of wireless connectivity. For those who aren't completely sold on mesh — or who don't want to take on the increased cost of a mesh system — TP-Link has created OneMesh, a relatively low-cost solution that sits somewhere between a router with range extender and a legitimate mesh system. I tried out the TP-Link RE300, one of just two range extenders with OneMesh capabilities, to see what it's all about and whether or not it's worth your time and money.
