AT&T Gigapower - Significantly Slower WiFi vs LAN speeds
I just got AT&T Gigapower (1 Gbps) installed and have run across a baffling situation.
I have the Pace 5268ac Gateway and an Asus RT-3100AC router. On both devices, I get LAN speeds of 600+ Mbps up and down. On Wifi, BOTH devices (tested independantly of each other) test out at no more than 150 Mbps up and down. I have used multiple 802.11AC devices to test the 2.4 and 5Ghz radios and get the same baffling results. I tested the ethernet/LAN the speed of the Asus router and it has no issue receiving 600+ Mbps from the Pace gateway. I have tried testing the AT&T gateway separately with my Asus router not connected and off. I have tried disabling WiFi on the gateway and solely using the Asus router for everything. Nothing changes.
I am testing this within 10 feet of the router in an open room. I have heatmapped my house for WiFi interference and currently only have 3 devices connected to the routers. I have no idea why the bandwidth dips so much when these devices (especially the RT-3100) are capable of much higher WiFi speeds. Any suggestions?
