I have multiple items on my network: thermostats, cameras, lights, etc. all use 2.4GHz connection switching to 5GHz isn't an option. Is there a limit to the number of devices I can have on my network? They don't access the internet consistently but do need connect from time to time which doesn't allow anyone else to use the connection they keep getting the access point temporarily full error message....full of what????
About 250 devices. Check the range of IP addresses on your router settings. I don't think the number of devices would be your problem but probably bandwidth. A router can only process so much. What's the make/model?
Im using the Panoramic Wifi router that comes with the gigablast service, I can get the model number if you need it.
CGM4140COM (Technicolor) also the IP range does cover 250 devices.
Of course it's Panoramic. I don't understand the conception of this thing as a router.
Another user had the same concern about Panoramic. There might be something useful.
Have you tried disabling the Cox Hotspot? See link below on how.
