Hello, does the modem reset when you lose WiFi service? Does this happen exclusively on WiFi or does this also happen on a hard-wired (Ethernet) connection? Are all devices experiencing intermittent connectivity? Your modem levels are within the normal specifications, and I'm not seeing any packet loss either. I am including an article that discusses ways to improve WiFi speeds. This article is also helpful for fixing intermittent connectivity on WiFi, as this issue could be related to inadequate WiFi coverage and/or network congestion.
