RBR20 with three RBW30 satellites drops connection repeatedly

Hi - 

Looked through a lot of posts on this community - tried several but have had little success.

Right now I have an Orbi RBR20 with three satellites. Each satellite is a RBW30 - according to the Orbi site they are running the most current firmware v2.6.2.104 for the rbr20 and version v2.6.2.2 for each of the satellites - I thought the issue might be the firmware difference but there is not a v2.6.2.2 version for the router that I could find.

Internet provider is comcast high speed - just checked and download spped is 106 Mbps and upload is 6 Mbps. 1500 square feet two level home

I was running this setup with the router and one satellite for a couple years but had connectivity problems (weak signal) in some rooms so purchased two additional satellites and set them up a little more than a month ago. Things were good - synched easily - and coverage has been much better and many fewer buffering episodes on amazon prime and Sling. We have about 5 amazon fire sticks that with 3 of them often in use plus two Galaxy S20s and two iphone 11s. We also have kids in school with chromebooks and both my wife and I are working at home with windows based PCs. About three days ago we started having connectivity to the internet problems - the smart phones and the chromebooks started dropping connections - things would be ok after rebooting the RBR20 router but would only last a few hours until we would start getting the "connected to wifi without internet connection" error messages. Funny thing is that the computers and fire sticks stay connected - mainly just the phones. And I am using the orbi managment app on my s20 which will say internet offline but will still let me do a speed test.

I am ok with technology but no tech whiz and don't geek out on this sort of stuff - I just want the system to work - especially since it is not cheap

So far I have been very dissapointed with the lack of support - I may have to be the extended support but have no idea what that costs - if I have to purchase another system to get adequate coverage and support I am not likely to buy another orbi or net gear product
