Hmm. I got my parents an Archer C7 based on it being the Wirecutter's pick for Best Wireless Router. It has been having a lot of problems with WiFi dropping out, like you describe. But I now see the Wirecutter have updated their comments [1] on the Archer C7:

"This is the single biggest reason we’re no longer recommending our former pick, the Archer C7. Though the C7 has great range and good single-device performance, it doesn’t have band steering, which means that it stumbles when several devices are connected and there’s a lot going on. The problem is compounded by the router’s relatively weak single-core CPU."

...our former pick, the Archer C7, leap all the way off the top of the chart into “oh, this is horrible” territory shortly past the 75th percentile — which means that roughly one out of every four page loads will leave you wondering if you should hit reload.

Well, I'm somewhat relieved to read that, in that I purchased one for the same reason but have been rebooting it at least once a day for a while now. I was initially relieved to see it may have been the Chromecast. Now I suppose it's both!
