I’ve been facing slow speed issues with my Nest Wifi Mesh. I have ATT Fiber and it shows full 500mbps at the gateway. The Main Google Wifi hardwired to the Gateway shows 590 download and the mesh connection test said “Great Connection”. However when i run speed test on different devices, it shows 40-50mbps download speed and even 15-20mbps at some times. I did not have much problem initially but now it’s affecting my work. Is Google looking into this? I saw a lot of posts with similar issues.
Try to disable all preferred activities (QoS basically):
And make sure no devices are stuck in priority mode:
And offload Wi-Fi (a shared resource between all wirelessly connected devices) by wiring as many devices as possible + use wired backhaul between Nest Wifi pucks with ethernet ports if possible:
