We have an xfinity cable box, wired to the asus rt-ac87u, and we run 2 wifi networks off of it, and every 8 hours it just stops working, including the wired internet, the xfinity works fine, but the asus doesn't. When it works its great, and this kept happening so I made it an access point only, and nothing changed, internet stops working every 8 hours.

How do I fix this?
I googled it and couldnt find anyone with this problem.
 
Solution
The DHCP renewal may be 8 hours on the XFinity modem - I would suggest creating a fixed IP address for the ASUS router using a MAC address reservation on the XFinity modem (i.e. 192.168.0.2). Whether or not it is in the access point mode, if it loses the IP address lease, it will crap out on you.
