RAX120 Router Random Disconnects

OK, so I have a ticket open with Netgear as well (42483200), for what appears to be this very issue. I am not as tech savvy as most of you, but I do know that my loss of connectivity is similar in nature to what is described by numerous others here. I also note that Windows tells me that when my internet is down, it is a DNS issue. I have isolated the connectivity issues to the router, and a router reboot (via app) always fixes issue, temporarily.

I recently upgraded my internet to Xfinity Gigabit, have a Netgear CM1100 modem connected to the RAX120, firmware 1.0.1.118. I am merely a home user who likes fast internet, and the ability to stream video on multiple devices while simultaneously performing other tasks. We have a variety of devices, including light switches, wall switches, desktop, laptops, iPhones, iPads, Chromecast, and Ring.

Now that I see that this is a pervasive issue with this router, and the unwillingness of Netgear to fix the issue, or even respond to direct questions within this thread, I'm here to ask:

What router do I get in it's place? I'm well within my return timeframe, and the support I've received from Netgear is quite lacking ("24/7 support" apparently means "wait on hold for our 1 customer representative; it may be many hours). I've been using email support instead, which is laborious and choked by inherent delays. I want a router that broadcasts far enough so that I don't lose signal from one end of the house (where the router is) to the other end (our bedroom). I want something that is as future proof as is feasible, within reason. The broadcast distance of the RAX120 is sufficient, and I thought I had a forward-looking router... but it doesn't even work.

Thank you.
