I would set up a bridge for an Ethernet connection and forget wireless. There are a lot of factors that impact throughput with wireless including distance from device to router, number of devices on the same BSSID, what the devices are doing (streaming, downloading, etc..), interference from other SSID's using the same channel as yours, your SSID's channel width ( 20 and 40 MHz only available with 2.4 GHz but 40 MHz should be rarely used) and your wireless router's capabilities.
