8-stream AX WiFi Gateway (CAX80)
Hello, I have 2 questions : 1) I have high speed 1Gbps internet connection and at time i see the issue with Upstream level. Xfinity is my provider and they confirmed that everything is good at ...
To add, CAX80 is my modem + router and I do not have a separate Modem from the ISP. My home is 2000+ sqft but has 3 floors.
Does 1 EAX80 sufficient for this?
Thanks,
Bala
You can lots of criticals that the ISP needs to review and resolve.
Please post a copy and paste of the modems connection status page.

For that size of home the CAX80 would be enough. If you add a EAX80, I would turn down the power on the CAX80 radios from 100% to 50%.
Here it is.
