Have Google Nest Wifi with two points. Been working fine for months. Today work laptop using Cisco anyconnect wouldn't work with wifi, said connected with no internet. Rebooted laptop, no change, rebooted both nodes, then cable modem and no change. On phone google app speed test passed with 340 mb/s download. Connected with hardwire cable fine. When I open a windows 10 command prompt and ping google (or any site) the first two pings work and the third fail, and it repeats. If I connect hardwired or to the cable modem wifi all pings work. Tried another laptop and same issue.

Sorry to hear about your issues with the Nest Wifi. My best suggestion is to try a factory reset on your entire Google Wifi setup. I wasn't sure if that is what you meant by saying rebooted the nodes and cable modem. Just unplugging it and plugging it back in doesn't always fix this type of issue but usually a factory reset does. Hope this helps!
