Because of lack of security
then define what you mean by lack of security !!! as just saying it means nothing as it has a nat like all routers have making it secure from the www in the first place , wireless security is the latest standard , the admin security is also as is the vpn security etc etc
lack of continued support past a few short months
i can assure you the new dlink gear is well supported the 890L has new beta fw in testing they just dont put it out to public b4 it should be and leave it to proper testers to evaluate
and a lack of willingness of those manufacturers to at least provide to their customers the best defense against security issues at the time when the device was new (by issuing it with broken, outdated and plainly incompetent code bits in the firmware),
i assume you are referring to what merlin is on about with tp link and its coding as there doesnt seem to be a lot broken with the 890L it lacks some features that asus have but then again its not asus is it
I do not see how anyone else can come to any other conclusion either.
because you are making generic sweeping statements covering every brand in existence outside asus without specifically being able to tell us if the statement applies to all of them
having tested and used the 89oL i can assure the OP that out of the list and place of purchase he has stated the 890L is by far the best router of choice and is fine for the standard home user , what you dont seem to understand is most dont care about what you are going on about , they care that it works and they dont have to spend hours setting it up and or swapping firmware every month and it performs well as far as wifi coverage and performance goes and even tim has indicated such in his reviews
You missed the part where he told
@fsrkewd to read and make up his own mind
Take a few minutes to see why right now, a router other than Asus is a bad decision
as i said if your going to make such sweeping statement you need to justify them not just send the OP on some goose chase google search he prob wouldnt understand or b bothered about
its simple , not everyone will or want to or will care about buying an asus , and ppl do buy other brands and have no issue at all and we need competition or asus would not push as hard as they do in the first place
dont get me wrong i love the asus gear its great but its also not the only fish in the sea as far as the consumer goes
but its no good for anyone if you run around like chicken little screaming the sky is falling without substantiating the claims and realizing who you are making the claims to , its not a one size fits all market and the user base doesnt have as great an exacting standard and can and will be happy with the alternative , objectivity is being able to see this
if you wish to specify your so called security concerns specifically when it comes to those brands mentioned in the OP and make it clear to the OP why these concerns should merit his decision by all means do so but im not going to debate you on generic sweeping statements , there is a great difference between old or bad coding and insecure or flawed , for the most part as i have mentioned above all router are secure in the important ways end users expect
