I had started with a Linksys router and that lasted almost a decade (the good old 54), used and had recommended many Linksys routers since then, but none could reach the stability or performance of that first one (as many can attest to).
I bought a few no names (for customers, based on their budget) that got returned immediately and then I started looking a little more seriously. That is when I discovered the Netgear 3700. What a huge upgrade from everything else I had used up until that point. But with very few firmware updates, issues that persisted for years and finally, what looked like hardware failure in my environment (it wasn't, the router is still working in a less demanding environment), I looked at what to buy next.
That is when the RT-N66U was bought. And then I discovered the RMerlin firmware. The comparisons to what I had for routers previously is like comparing a bicycle to a spaceship (okay, I'm exaggerating for effect
).
Sure, it is a little frustrating to see fixes coming so often and other offerings may seem more stable in comparison. But the reality is that a router is a computer and a computer that is not kept updated is fairly limited in its usefulness (especially when it needs to be online).
As a router is the first point of our networks that is 'online', the continuous updates that Asus is committed to is a breath of fresh air from my point of view, not an indication of less quality, but rather a way to use equipment from 3, 4 and more years ago safely, today and tomorrow too.
Sure, I've made customers networks run acceptably with other brands. But interestingly, the ones that run the various Asus routers I've recommended are the ones that are most likely to ask their home network be upgraded to an Asus (like at work).
I've replaced once top of the line DLink routers with a $30 Asus and the owners couldn't believe the upgrade their network received. Yes, a few years makes a huge difference for technology items. But this particular customer called me to ask to get a new, current DLink router working for them. I did; the solution, get rid of the DLink.
