RAX40 Drops internet and has to be rebooted almost daily

I battled this issue for a month with this router. I had to reboot nearly every day; some days 3-5 times.  I tried everything that tech support suggested with about 10 hours on the phone through multiple calls.   have a Sonos system and Google Nest and some of these only work on 2G and have some incompatible routers, but the RAX40 was not listed as one of them.  I tested a Linksys Velop router with 3 units, so I could check if maybe it was related to the Spectrum cable signal or the modem.  I have not lost the internet once in over a week with the Velop system and running all the same devices.  The RAX40 is being returned; for whatever reason it didn't work for me.
