StreamLocator developed a proprietary OpenWRT based firmware running on Wi-Fi 802.11bgn 300Mbps router based on Qualcomm QCA9531 chipset.
It has 1 WAN and 4 LAN 100Mbps ports for wired connection and comes with ethernet cable and a power supply.
We tested the router in a 4,000sqft house and we measured the speeds in the 35 - 70Mbps. range. Wi-Fi 802.11n on 2.4Ghz provides the best range (lower frequencies have better range) and it's fast enough for 4K streaming.
5 Mbps is required for HD streaming while 25 Mbps needed for 4K streaming.
