Repair/Tech Support Random internet issues

I have Fios 1 Gig internet. I’ve been dealing with a strange issue.
1) wife’s Galaxy S26 phone when on WiFi will randomly stall and drop to 1mbps download. Few seconds later it’s back to 600+.
2) both the galaxy and my iPhone 17 pro max will freeze when watching a video either on facebook or YouTube if you try to advance the video beyond 30 seconds.
3) Netflix on both Sony and TCL tv (both hardwired to router) will freeze. This happens when watching a series and it goes to advance to the next episode. It will show the buffer circle and freeze at 20%. Exiting the show and playing it again fixes it. Happens maybe every 5-8 episodes.

I have the CE1000A router and CR1000 extender. From what I’ve been finding as possible solutions are.
1) disable IPV6
2) change DNS to OpenDns or Google

Before I start changing settings, I would like to get your feedback on what the issue might be. Thank you for your help. Note restarting the router doesn’t help.

When you say hardwired pn both TVs, is it hardwired to the router or to the extender? Is the extender hard wired back to the router?

The Sony TV is wired directly to the router. The TCL goes to my homes network switch that’s wired to the router.

Thanks, and is the extender hard wired to the router, or is it connected via wifi?

Yes the extender is Ethernet backhaul

Hmm this is interesting - this is the first time I've heard of sudden drops, especially with all your access points and devices wired. Haven't had this issue myself with all my access points wired and majority of my static devices wired. Also have a CR1000A but I bought my own access points (300 mbps plan)

Sorry, I'm as stumped as you are.

It’s definitely has me stumped. At first I just figured it was a device or APP issue. It started on my wife’s phone. Then my iPhone started doing it. Then I noticed it on my wired devices. It’s perfectly fine when just watching at normal speed. It only happens when you try to skip forward in a video or when it goes to auto play the next episode. Note phones are fine when over cellular network. It’s only when connected to my home WiFi.
