From a stability standpoint, I have had no issues whatsoever. I have posted three threads here .. 1) about not being able to see our wide format plotter .... one about using USB printer plugged into router as a networked printer and another regarding Windows error messages about name resolution for some hub thing that I have no idea what it is. These questions have also been submitted to Asus tech support by phone (1st level was incoherent and answers were unrelated to questions, said 2nd level would call back later) ... still waiting. E-mail inquires have been non responsive addressing questions I didn't ask. The sent me a link to to a MFP utility without mentioning what it is for or what problem it addresses.
I saw all the issues before the latest firmware and I can say I have never experienced any of those... however the complete lack of responses from tech support would have me recommending that you do not purchase any Asus products at all. We have been building PCs since the early 1990s and pretty much used Asus MoBos and GFX cards exclusively, later adding mice, Monitors and other products. At this point, having been disappointed recently with Tech Support on many products, unless things change (before the return window expires on this router) , will be taking all Asus products off our component offerings.
