I bought a Rosewill RNX-N250PCe - Wireless N300 Wi-Fi Adapter for my desktop, running Ubuntu 16.04, and I'm getting about a third the number of Mbps as my laptop.
Using lspci -v, I get that the wireless card is: Realtek Semiconductor Co., Ltd. RTL8192CE PCIe Wireless Network Adapter.
Does anyone know how I can get back the other two thirds of my bandwidth?
