Wifi working for 50% of devices yhis morning. (alien.top)

I have a SmartRG SR400AC. The is morning, without us having changed any settings, 50% of devices that worked fine yesterday have wifi problems. The Android 12 phone I'm writing this on is connected fine. My son's Android 11 tablet won't connect to wifi and keeps repeating the "Obtaining IP address". Our Roku is connected fine and my son's watching a show with it. My work laptop (HP ZBook running Windows 11 Enterprise) is giving the mystifying "Connected, No Internet" message and I can't connect to the VPN.

I tried "/ipconfig flushdns" on the laptop - although I don't know if the system admin setup will allow that to work. I have unplugged and replugged the router, and pressed the reset button on the back. No changes. Going to 192.168.1.1, 192.168.0.1, and 192.168.1.100 on the phone's Chrome doesn't connect to anything.

Any ideas what else I can do?

On a connected device check the IP detail to determain your Default gateway and login to your router and see what is going on.

Also once you know your IP range i.e. 192.168.1.0/24 or depends what is your router distributing you can always put a static IP on a laptop and see if you can connect to the router, ping the router and go to the Internet.

Maybe somehow your DHCP pool is full not sure need to check this on your router.

Thanks
