    Amazing FEATURES for such a price
    Asus-WRT is feature rich, beautiful UI and it runs smoothly on this device; VPN (server / Client ) options is a huge plus. On this device you get Asus AiCloud, parental control, network bandwidth monitoring, QoS configuration, etc.
    Dual band with independent configuration for each
    You have up to six guest WiFi networks to create and manage, that means I get up to eight SSIDs from one router
    Device is light weight, easy to travel with so you can use to extend your USB internet dongle away from home

    Fast shipment as well - under one week from order to receive
    Absolutely None at this price (would be awesome if it had Gigabit Ethernet ports and SSIDs could have separate IP address pool - DHCP)

    good device\good price
    1.коробка приехала мятая, но ничего не пострадало, 2.комплектация из Китая: коробка+сам роутер+блок питания+переходник на евровилку+ 2 бумажки, всё, 3.покупал с пойнтами, потому ценник в 1800р. для России(самое меньшее-2900р. в DNS) просто сказка, 4.работает без нареканий, это Asus, 5.настройка легкая, уже был русский язык, хотя не просил, и коробка была запаяна, 6. 2 диапазона, 7. ну и опять это Asus.
    убогая комплектация: даже LAN-шнурка нет, хотя он на фиг не нужен.

    Good Router
    I had some doubts about buying a router through this page, but when i recieved the router (just 1 hour ago) i realiced that the router was well worth the price.

    The interface of the router came in my native language (spanish), so i had no troubles setting it up, also, it has a lot of options to customize your configuration.

    Buy this router with confidence, it is a high quality product.
    The only trouble that i had is that the printed manual is on chinese, it could be printed on english as well.

I would like an answer on three questions: 1. Does it come with English language, and if not, can you update it to English version? 2. I would need EU adapter, does it come with one? 3. What speed are those 4 LAN ports, not wifi, but LAN ports, 100mbit or 1000mbit? I see you tried to answer on these questions, but some of them you misunderstood and did not answered what you have been asked. Thank You.
