Weird intermittent, partial / full, internet drops.

Few times daily my whole local connection either cuts out for a second or two. I tried to dig around and actually see if it was happening on my side of the fence, vs the other side and it seems everything on my side of the modem is functioning fine. I'm just using the XB8 as my sole modem. It's very noticeable depending on the game being played, but a few it is consistently making the experience unplayable. All standard troubleshooting tricks didn't work, and the xfin assistant just says it found an issue and then does nothing about it. It does mention I'm eligible for an equipment update, but then the hyperlink is broken and doesn't work. Pretty impressive to be honest, pretty cool. I'm at the wits end so I'm just throwing this out as a random shot in the dark.
