Tenda AC1200 Dual Band WiFi Router, High Speed Wireless Internet Router with Smart App, MU-MIMO for Home (AC6),Black

Después de muchas dudas y mirar opiniones, me “arriesgué” porque no conocía esta marca. Tenía el problema de todos los adosados con las plantas de arriba y, después de hacer llegar un cable Ethernet y conectar este router Inalámbrico, funciona con mucha rapidez. Antes había usado un modem viejo de Telefónica, adaptado como router, pero tenía poco alcance y se desconectaba frecuentemente; ahora llega al piso de abajo (dormitorios) mejor que el modem de entrada y en 5G, a una velocidad más que rápida. (Cuando le haga pruebas de velocidad las adjunto)

This is based on a setup I did last night, so durability is a preliminary call. I got this for my girlfriend. Her Netgear 1600 is approaching old age and had a bit a bit of occasional cutout on the high band. Not enough to make it unusable, but at the sale price of the Tenda, I was able to buy one and save the Netgear for a spare in case something really failed.

I paid good money for a Netgear Nighthawk 1900 for my home, and after installing an AC1200 in a rental property I came to the conclusion that all that extra power in the router is wasted if you’re only getting 60 megs down through the cable system.

The Tenda cost a small fraction of my locally purchased AC1200 unit and works as well as anything I’ve used. I was able to hang nine devices–Roku boxes, Amazon units, smart speakers, phones, tablets and computers on it in a matter of minutes. It had enough power so that I was getting good signal on my phone way out on the street, at least a block from the unit. If anything more expensive dies in the router department (and the spare Netgear unit dies), this will be my new go to router. Now I’m asking myself what was I thinking when I laid out that extra $140 to get that high end Nighthawk.

I won’t even lie. This router worked great for me – strong signal, fairly insane speeds; I was getting 75mbps down (5GHz channel) and I’m pretty sure I only have a 30mbps Comcast plan. Good admin interface, everything checks out, and the price sure was right.

But some vulnerability/backdoor (specifically something IPV6-related, as I noticed lots of strange traffic through that, and I normally never used ipv6 previously) got my ENTIRE house full of computers infected with a Windows Management Instrumentation (WMI) related malware, where the attacker remotely modified my Windows installation to be set up as an Active Directory client, as if my PC thought it was on a corporate network, beholden to the IT administration’s control. So my group policies almost all set themselves to “Managed”, and I couldn’t change them myself. It also spread itself to any new USB media I made with windows’ official Media Creation Tool, I believe through auto-generated malicious autorun.inf’s under invalid pathnames, like D:\System Volume Information\:\:autorun.inf (windows doesn’t allow colons in pathnames), among many other weird and not-easily-detectable signs of tampering in my machine. Before I even noticed something was amiss, it had taken control of all the other PCs in the house including my girlfriend’s. Even after a full drive wipe on any given computer, the malicious presence remained in the background.

Just google “Tenda vulnerability”, specifically Loki Labs’ article “Tenda, is this a bad design or a backdoor?” to see what I’m talking about. Also read up on WMI malware, such as the recent Astaroth malware which I think might’ve been part of the type of virus I acquired, and how notorious and ancient it is as a method to compromise computers remotely. If you buy+use this router for a few days it’s likely you’ll even pick up a remote attacker on your network and not be able to notice it, except for some innocent-looking COM Surrogate Provider, rundll.32, Font Caching etc. (the list goes on and on) processes that blend in entirely with the operating system, because they are built-in to it. You’d be surprised just how insidious this type of infection can be, especially if you try to remove it without locking down your home network security impeccably before starting the reinstalls and everything.

I’ve been tinkering with computers since I was almost a baby; develop software for a living and I’ve never seen anything quite like this until now. I’m still trying to get rid of it completely, after 2+ weeks of late nights and headaches, thinking I might’ve vanquished it this time only to find another subtle but unmistakable sign of infection. I’ve obviously ripped this router out and am preparing to return it, using my old wireless-N router for the moment, but even still this stupid attack seems to persist on all my computers, even on Ubuntu/linux (!!!), as I believe it got access to some of my laptops’ UEFI firmware somewhere along the way… it’s terrible, trust me, just don’t mess with the Chinese brands if you value your time and privacy. I never cared either until this incident but you can bet your butt I have learned my lesson, firmly.

Boa tarde, recebi meu produto dentro do prazo estipulado, mas o mesmo após verificar a caixa e seus componentes, havia indícios de que o mesmo já havia sido configurado e utilizado anteriormente (plásticos que envolviam o equipamento apresentam “deformações” típicas após o uso e manuseio do mesmo)
O mesmo já carregava configurações assim como nome da rede (Gomes) e senha, conforme imagem.
