@rojomo I ended up just giving it a shot since Costco is good for returns... I have had it for a couple of weeks and and I am happy with so far. It works and I don't think about it, which seems like a really good thing for a router
.
I did just now find one review from DongKnows where he describes it as a decent router if you don't need high end features. We are 2 adults, don't need parental control features and don't have several simultaneous 4K streaming sessions going, so it works for us. And despite the fact that I actually like fiddling with a router, having it work reliably is also very nice!
