Frequent Internet Drop-out

[Marko]

Have been experiencing frequent internet loss, having to constantly reboot the equipment.  Spectrum replaced their modem and tested lines and claimed they were all performing properly.  System worked for 24 hrs., then started dropping internet again.  Assuming their replaced modem is working properly, I'm not sure how to determine if I have a Ruckus issue or if my wifi router is the culprit.  Suggestions appreciated.
