Panoramica
The EXO AC2600 MU-MIMO Wi-Fi Router brings a host of new technologies to create the best Wi-Fi experience to date. Supporting the latest in Wi-Fi technology, with combined Wi-Fi speeds of up to 2,533 Mbps, it allows you to create a home Wi-Fi that connects all of your computers, game consoles, smart  TVs  and  mobile  devices.  AC  SmartBeam™  together  with  MU-MIMO  technology  brings  you the  future  of  high-bandwidth  wireless  connectivity,  further  increasing  the  speed  and  coverage  of your network.

Superior Coverage and Speed with Advanced AC SmartBeam™
The  DIR-882  upgrades  your  network  to  the  latest  dual-band  high-speed  wireless  technology to bring you lightning fast Wi-Fi speeds of up to 2,533 Mbps, so you can meet the increasing demand  from  multimedia  applications.  Enjoy  seamless  high  definition  streaming  media, Internet  phone  calls,  online  gaming  and  content-rich  web  surfing  throughout  your  home  or office.
In addition, 10/100/1000 Gigabit Ethernet ports give you solid, dependable wired performance for devices such as Network Attached Storage (NAS), set-top boxes and gaming consoles. The built-in Quality of Service (QoS) engine allows you to prioritise important traffic to ensure that your favourite applications are receiving optimal bandwidth.

Smooth Streaming with Wireless 802.11ac Wave 2
The  DIR-882  brings  a  host  of  new  technologies  to  create  the  best  wireless  networking experience to date. With 802.11ac Wave 2 technology, it provides Gigabit wireless connectivity with combined transfer rates of up to 2,533 Mbps (1,733 Mbps Wireless AC + 800 Mbps Wireless N). Featuring Multiple-User MIMO (MU-MIMO) technology, it can send and receive data to and from devices simultaneously to increase speed and efficiency. It is like having multiple routers in your home.

File Sharing at Your Fingertips
The  DIR-882  lets  you  connect  a  USB  storage  device  and  instantly  share documents, movies, pictures and music. You can have your music library on a USB drive and share it with your entire home. You can show photos on the living  room  TV,  while  a  family  member  watches  a  movie  on  their  computer.  
You can stream media files to multiple devices without interruption, or save them to your device for offline playback.
The  intuitive  interface  lets  anyone  immediately  connect  to  a  variety of entertainment options stored on your own storage device.

Hassle-Free D-Link Smart Connect Technology
Ever  since  the  introduction  of  5  GHz  wireless  technology,  users  have  had  to blindly guess whether the 5 GHz or 2.4 GHz band would provide them with the best  networking  experience.  D-Link’s  Smart  Connect  Technology  eliminates this confusion by automatically distributing devices to the optimal network.
Simply initiate a connection to the DIR-882 and its advanced algorithms will determine the best network for your device to connect to, thereby ensuring a faster, more reliable and hassle-free experience.

Easy to Set Up and Secure
Sharing your Internet connection doesn’t have to be a complicated process: just open a web browser to access the setup wizard and follow the easy step-by-step  instructions  to  get  started.  Configure,  apply  and  set  up  WPA/WPA2 wireless security in minutes with the wireless network setup wizard, or use Wi-Fi Protected Setup (WPS), which establishes an encrypted connection to new
devices without the need to enter settings or create passwords. In addition, the built-in firewall requires no setup, protecting you against malicious attacks from  the  Internet  and  access  control  features  allow  you  to  restrict  access  to your network giving you greater control over network users.

Istruzioni di installazione. Attenersi alla seguente sequenza:

1) Resettare il router tramite interfaccia web;
2) Aggiornare una prima volta il router caricando manualmente il file 1_DIR-882_RevA_MiddleFirmware.bin. Attendere il tempo necessario all'aggiornamento (circa 4 minuti);
3) Aggiornare per la seconda volta con il firmware 2_DIR-882_RevA_Firmware102B02.bin ed attendere che il router effettui il riavvio (4 minuti circa).
4) Resettare nuovamente il router alle impostazioni iniziali di fabbrica tramite l'interfaccia web e NON utilizzare file di configurazione salvati in precedenza con versioni diverse del firmware.

DIR-882 Firmware Release Notes

Firmware: 1.02b02
Hardware: Rev. Ax
Release Date: 2018/02/09

Note:
This release is to patch the WPA2 Key Reinstallation Attack (KRACK) Security Vulnerabilities affecting this product.

Problems Resolved:
A WPA2 wireless protocol vulnerability was reported to CERT//CC and public disclosed as: VU#228519 - Wi-Fi Protected Access II (WPA2) handshake traffic can be manipulated to induce nonce and session key reuse.

The following CVE IDs have been assigned to VU#228519. These vulnerabilities in the WPA2 protocol:

   ·   CVE-2017-13077: reinstallation of the pairwise key in the Four-way handshake

   ·   CVE-2017-13078: reinstallation of the group key in the Four-way handshake

   ·   CVE-2017-13079: reinstallation of the integrity group key in the Four-way
       handshake

   ·   CVE-2017-13080: reinstallation of the group key in the Group Key handshake

   ·   CVE-2017-13081: reinstallation of the integrity group key in the Group Key
       handshake

   ·   CVE-2017-13082: accepting a retransmitted Fast BSS Transition Re-association
       Request and reinstalling the pairwise key while processing it

   ·   CVE-2017-13084: reinstallation of the STK key in the PeerKey handshake

   ·   CVE-2017-13086: reinstallation of the Tunneled Direct-Link Setup (TDLS)
       PeerKey (TPK) key in the TDLS handshake

   ·   CVE-2017-13087: reinstallation of the group key (GTK) when processing a
       Wireless Network Management (WNM) Sleep Mode Response frame

   ·   CVE-2017-13088: reinstallation of the integrity group key (IGTK) when
       processing a Wireless Network Management (WNM) Sleep Mode Response
       frame


This patch also included fixes for DNSmasq vulnerability:

   ·   CVE-2017-14491 ­ Remote code execution in the DNS subsystem that can be
       exploited from the other side of the internet against public-facing systems and
       against stuff on the local network. The previously latest version had a two-byte
       overflow bug, which could be leveraged, and all prior builds had an unlimited
       overflow.

   ·   CVE-2017-14492 ­ The second remote code execution flaw works via a heap-
       based overflow.

   ·   CVE-2017-14493 ­ Google labels this one as trivial to exploit. It's a stack-based
       buffer overflow vulnerability that enables remote code execution if it's used in
       conjunction with the flaw below.

   ·   CVE-2017-14494 ­ This is an information leak in DHCP which, when using in
       conjunction with CVE-2017-14493, lets an attacker bypass the security
       mechanism ASLR and attempt to run code on a target system.

   ·   CVE-2017-14495 ­ A limited flaw this one, but can be exploited to launch a
       denial of service attack by exhausting memory. Dnsmasq is only vulnerable,
       however, if the command line switches --add-mac, --add-cpe-id or --add-subnet
       are used.

·   CVE-2017-14496 ­ Here the DNS code performs invalid boundary checks,
    allowing a system to be crashed using an integer underflow leading to a huge
    memcpy() call. Android systems are affected if the attacker is local or tethered
    directly to the device.

·   CVE-2017-13704 ­ A large DNS query can crash the software
