Netgear: 11 routers vulnerable to remote hacking

By: Anthony Garreffa | More News: Connectivity & Communications | Posted: Dec 16, 2016 7:33 am

Security researcher Andrew Rollins has discovered 11 different models of Netgear routers that have been vulnerable to remote hacks, with Rollins even warning Netgear about the problem all the way back on August 25, but didn't receive a reply.

Rollins went public with the announcement after waiting 3 months, which saw Homeland Security throwing out a warning a few days ago, and now Netgear is finally in the fold, admitting that it knows about the problem. Netgear has announced the affected models, and will release patches... for some of them.

 

Here's the list of the affected routers:

 

  • R6250*
  • R6400*
  • R6700*
  • R6900
  • R7000*
  • R7100LG
  • R7300
  • R7900
  • R8000*
  • D6220
  • D7000

 

Netgear has patched the R6250, R6400, R6700, R7000 and R8000 - but it's not easy, as you'll need to manually update your Netgear router, as the company doesn't have a way of providing over-the-air updates. Netgear hasn't said a word on whether they'll be updating the other models just yet, but Rollins did talk with Wired, where he said it's "not that hard to fix at all".

Engineering milestone: Wi-Fi uses 10,000x less power

By: Anthony Garreffa | More News: Connectivity & Communications | Posted: Dec 13, 2016 2:34 am

How many devices do you have in your house that use Wi-Fi? I'm sure there's at least a few, and if you're like me and many others - you'll have over a dozen devices with Wi-Fi, so when engineers reach a breakthrough with Wi-Fi that uses 10,000x less power - it'll make you sit up and pay attention.

 

 

Engineers from the University of Washington have achieved speeds of 11Mbps on the new connection, so it's not breaking speed barriers - but they're working on getting the speeds faster, and faster. The new Wi-Fi transmissions use 10,000x less power than conventional methods, so battery life savings on smartphones and mobile devices will improve by a considerable margin in the future.

 

One of the engineers, Shyam Gollakota, explains: "We wanted to see if we could achieve Wi-Fi transmissions using almost no power at all. That's basically what Passive Wi-Fi delivers. We can get Wi-Fi for 10,000 times less power than the best thing that's out there".

New HDMI 2.0b spec announced by format working group

By: Ben Gourlay | More News: Connectivity & Communications | Posted: Dec 12, 2016 7:08 am

Ahead of next month's CES event in Las Vegas, the HDMI forum, which consists of the major players from consumer electronics companies, mobile devices and cable manufacturers have ratified a major update to the HDMI cable specification, dubbed version 2.0b.

 

new-hdmi-2-0b-spec-announced-working-group_01

 

In an announcement today, the HDMI forum revealed the update to the format includes the following capabilities:

 

  • Enables transmission of High Dynamic Range (HDR) video
  • Bandwidth up to 18Gbps
  • 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution
  • Up to 32 audio channels for a multi-dimensional immersive audio experience
  • Up to 1536kHz audio sample frequency for the highest audio fidelity
  • Simultaneous delivery of dual video streams to multiple users on the same screen
  • Simultaneous delivery of multi-stream audio to multiple users (Up to 4)
  • Support for the wide angle theatrical 21:9 video aspect ratio
  • Dynamic synchronization of video and audio streams
  • CEC extensions provide more expanded command and control of consumer electronics devices through a single control point
  •  

    While some of these features were enabled in earlier specifications by individual manufacturers, the ratification by the working group should mean improved functionality throughout the sector. Thankfully, the updates is also fully backwards compatible with the HDMI 2.0a specification, with no need to purchase new cables to unlock the new features. Expect to see more about HDMI 2.0b at next month's CES event in Las Vegas.

    Apple rumored to drop wireless router development

    By: Sean Ridgeley | More News: Connectivity & Communications | Posted: Nov 22, 2016 3:43 am

    After slowly moving employees to other areas of the company, Apple has now dropped its wireless router development division entirely, sources are saying. The company declined to comment on the matter.

    Apple's wireless router lineup includes the AirPort Express, AirPort Extreme, and AirPort Time Capsule, which sell for $99, $199, and $299, respectively. All are said to have lagged behind other top router manufacturers in the adoption of new standards.

     

    Combined with Apple Watch and Apple TV sales, the wireless router lineup generated $11.1 billion and 5 percent of sales for Apple in fiscal 2016.

    This is the first ever Internet message sent

    By: Lana Jelic | More News: Connectivity & Communications | Posted: Oct 29, 2016 2:24 pm

    A variety of apps are used today to send tens on billions of messages every day. We use chat apps, like Facebook Messenger, Viber, WeChat, and WhatsApp, to communicate with our friends, family, and colleagues.

     

    first-internet-message-sent_01

     

    On this day, October 29th, 1969, 47 years ago, the first ever electronic message had been sent. The message was sent by UCLA student programmer Charley Kline trough ARPANET, the precursor to the modern Internet.

     

    At the time, ARPANET was used for testing new network technologies, and it connected many universities and research centers. The first two nodes of the ARPANET were the University of California, Los Angeles, and the Augmentation Research Center at Stanford Research Institute, between which the first ever message exchange took place.

     

    The UCLA professor Leonard Kleinrock and his student Charley Kline sent the first message to Bill Duval at Stanford University. Kline wanted to send the message containing the word "login", but the system crashed after he entered the letter "o", meaning that the first ever internet message was - "lo".

    Google pauses its Fiber rollout, fires 9% of Fiber staff

    By: Anthony Garreffa | More News: Connectivity & Communications | Posted: Oct 26, 2016 8:00 am

    After a pretty successful rollout of uber-fast internet access, Google has announced it has plans to "pause" the expansion of its Fiber rollout into 10 more cities, as well as a 9% cull in Fiber staff.

     

    google-pauses-fiber-rollout-fires-staff_11

     

    Google's current Fiber customers will not be affected, but those that were expecting the high-speed Fiber goodness to hit their neighborhood will not want to even read the end of this sentence. The confirmed rollouts in San Francisco, Irvine, Huntsville and San Antonio are all unaffected, but the planned Fiber rollout for Chicago, Dallas, Portland, Tampa and San Diego will have residents disappointed.

     

    The reason behind Google's sudden "pause" in its Fiber rollout? Google said it needed to "stay ahead of the curve" in providing gigabit internet service, with the company recently acquiring high-speed wireless ISP, Webpass. If we end up seeing Google push into providing high-speed internet access wirelessly, it would explain why it stopped the future Fiber rollouts because physical hardware being installed all across the US is expensive compared to a new wireless system.

    Nokia tests 52Gbps fiber internet in South Korea

    By: Anthony Garreffa | More News: Connectivity & Communications | Posted: Oct 20, 2016 7:26 am

    I feel like a king with my 100Mbps fiber connection, and when I talk to friends like Ryan Shrout over at PC Perspective who has 2Gbps fiber - I can't help but feel like I'm about to cry. First world problems aside, Nokia has teamed with SK Broadband to test a new broadband service capable of bursting up to 52.2Gbps.

     

    nokia-tests-52gbps-fiber-internet-south-korea_09

     

    SK Broadband needed to use multi-dwelling units (MDUs) from HFR and Nokia's universal next generation passive optical network (PON) technology. SK Broadband and Nokia used the following tech:

     

    • TWDM-PON: 40Gbps symmetrical
    • XGS-PON: 10Gbps symmetrical
    • GPON: 2.5Gbps symmetrical

     

    SK Broadband's network division boss Yoo Ji-chang explained: "As a new era looms that demands gigabit Internet, ultra high definition video and virtual and augmented reality services, SK Broadband will establish a network infrastructure that provides the best customer value. Following the world's first commercialization of an ADSL service and the two-pair LAN cable 500M service, we will establish a top-class optical Internet platform to create the best gigabit broadband service environment for our customers".

    5Gbps Ethernet on the way, will use your old cables

    By: Anthony Garreffa | More News: Connectivity & Communications | Posted: Oct 3, 2016 9:21 am

    Over the last couple of weeks I've been complaining that my 1Gbps network connection to my NAS was too slow, as I was only transferring to and from my Thecus and QNAP NAS at 100MB/sec - well, 5Gbps networking is on the way, promising 500MB/sec.

     

    5gbps-ethernet-way-use-old-cables_07

     

    The new 5Gbps Ethernet standard has been finalized, with IEEE 802.3bz ready for the job - soon, at least. We've been sitting at a wall for a while now on gigabit ethernet, because 10GbE requires much more expensive cables in the form of fiber optic, or more expensive Cat6a or Cat7 cabling. It's not backwards compatible with previous standards, as well as routers, switches, and network cards for 10GbE networking being much more expensive than the normal GbE products.

     

    This is where the new 2.5GBASE-T and 5GBASE-T standards step up, both "specifically created to use 10GbE signaling, but at a rate that would be compatible with existing runs of Cat5e and Cat6 cable out to 100 meters. The 2.5Gbps standard can run on Cat5e out to 100 meters, while the 5Gbps standard requires Cat6 cable to run 100 meters. Both should be far easier - and cheaper - to bring to market than current 10GbE technologies", reports ExtremeTech.

     

    Now we need to see AMD and Intel bringing out chipsets in the near future with 2.5/5GBASE-T compatibility, so that our SSDs that push 500MB/sec can now do it over our networks. Oh boy.

    Google's 4K-ready Chromecast Ultra teased at just $69

    By: Anthony Garreffa | More News: Connectivity & Communications | Posted: Sep 27, 2016 2:11 am

    Google is mere days away from unveiling its new Pixel and Pixel XL smartphones, as well as their new Andromeda operating system which is said to be an infusion of Chrome OS and Android, and could be the next big thing which will be ready in 2017.

     

    googles-4k-ready-chromecast-ultra-teased-69_01

     

    The upcoming hardware-focused media event should see a bunch of new devices unveiled by Google, with notorious leaker Evan Blass teasing the Chromecast Ultra. Google's purported Chromecast Ultra is a 4K-ready device, which will have the same form factor as the current Chromecast, but it not features a "G" insignia, with the Chromecast logo removed.

     

    The new 4K-ready Chromecast rocks a physical button, which could be used as a reset button, or an on/off switch. Google will reportedly be shipping the new 4K-powered Chromecast Ultra in October, for just $69.

    1Tbps fiber optic tested, could become a reality soon

    By: Anthony Garreffa | More News: Connectivity & Communications | Posted: Sep 19, 2016 1:47 pm

    As I type this, I'm connected to a 100/40Mbps fiber connection with the National Broadband Network (NBN) here in Australia. It's one of the fastest connections you can get, but 1Gbps seems like a distant goal for most people - and now we're already hearing about 1Tbps connections.

     

    1tbps-fiber-optic-tested-become-reality-soon_06

     

    Recently, Nokia Bell Labs with the help of Deutsche Telekom and the Technical University of Munich have teased 1Tbps connectivity in a field trial that involved "real conditions" like varying channel conditions and traffic levels. The difference here was a new modulation technique called Probabilistic Constellation Shaping.

     

    Engadget reports that instead of using "all the networking's constellation points (the "alphabet of the transmission") equally, like typical fiber, it prefers those points with lower amplitudes -- the ones that are less susceptible to noise. That helps transmissions reach up to 30 percent further, since you can adapt the transmission rate to fit the channel. It's so effective that the team got close to the theoretical peak data speeds possible for the fiber connection".
