If you buy a refurbished unit be sure to purchase it from an outlet that will let you return your unit as some of the units manufactured in 2018 have had hardware issues so if the unit hasn't been thoroughly tested you may get someone else's problem child.Thanks for sharing
For the most part I have no problems with refurbished routers. The AC86 IMHO is a special case. In fact I used a refurb AC1900P which I purchased to fill in while I was going through multiple RMAs with ASUS when my original AC86 crapped out and then several of the refurbished AC86s they sent me in exchange were duds right out of the box.Agree Refurbished units do have these kind of issues, I always buy refurb products from the outlet which let me return it, thanks for the heads-up
i got a steal on a ac3100 from a craiglist seller after light use (he went with some orbi mesh pucks) and notice these asus routers run crazy hot 80°c so i added a $5 usb fan to mine week one it's been working hard over a year now without issue. i suspect a lot of these asus that die in a year or two are simply overheating, and any cheap fan use will extend it's life by years. maybe asus are made to handle heat, but after running a linksys wrt1200ac for years at 60°c, i wasn't going to take any chancesrouter crapped out shortly after its one year anniversary.
