I have started getting issues with multiple devices on my network where they are connected to the network, but do not get internet.
After doing some digging, I noticed that all of those device are showing a different IP address. My regular network (all my Google Wi-Fi devices) have IP addresses in the range 192.168.86.XXX but my devices that aren’t working show IP addresses of 192.168.87.XXX The router shows those devices are supposed to have a .86 subnet, so those numbers aren’t matching. I happen to know that the .87 subnet is for the guest Wi-Fi network, but all my devices are connected to my regular network. I noticed that one of my Google Wi-Fi points (not the router) was also showing a .87 subnet so I reset that device and it’s working now. That fixed the devices for a couple of days, but now they are switching back to the .87 subnet while all the Wi-Fi points are still on .86
The devices experiencing these issues are windows laptops, iOS devices and a nest cam (so I don’t think this issue is coming from the devices, I think it is my router).
Any ideas for what is going on?
Thanks for reaching out. I'm sorry to hear that you're having an issue with the connection of some of your devices. I'd love to know more about what's happening. Can your other devices rhat has .86 subnet communicate with the devices that have .87 subnet? Also, to isolate the issue, could you try forgetting the network on atleast 1 device that has .87 subnet and reconnecting it again and observe if it will switch back to .87?
Looking forward to your response.
