Devolo dLAN 550 Doubles WiFi



Devolo LogoPowerline specialists Devolo have given their mid-range adaptors a makeover, boosting speeds and updating the styling in line with the top-end models. The new dLAN 550 series takes over from the 500s, offering greater in-house range and faster WiFi transmission rates.

dLAN 550 WiFiThere are two powerline adaptors in the 550 series, the Duo+ and the WiFi. As might be guessed, the Duo+ is the wired version and WiFi is the one with wireless. The wired range has been boosted by a third from a notional maximum of 300m to 400m, though this will be affected by local circumstances.

The most noticeable change is likely to be with the WiFi unit. The wireless speed has been doubled, going from 150 Mb/s in the old 500 to 300 Mb/s in the new 550, courtesy of 2×2 MIMO (multiple input, multiple output) technology.

550 adaptors can easily be added into an existing dLAN powerline setup either using the Cockpit software or simply pressing buttons on the adaptors. Further, Devolo’s WiFi clone feature can reproduce an existing wireless network so that laptops and tablets see only one network and seamlessly switch to the strongest signal.

The dLAN 550 WiFi is now available online and in stores. The Starter Kit costs GB£99.99 and consists of a dLAN 550 WiFi and an additional dLAN 550 duo+ adapter. A Network Kit with three adapters (two 550 dLAN WiFi adapters and one dLAN 550 duo+) is available for £149.99, while single adapters for extending the WiFi network are available for £59.99.

GNC will be having a hands-on review of the dLAN 550 Starter Kit shortly.


Devolo Boosts Speed By 20% For dLAN 1200+



Devolo LogoGood news if you are a Devolo powerline user with dLAN 1200+ products in your home…Devolo have announced a new free firmware update which gives a 20% bandwidth boost. The firmware will be available shortly for installation and owners can either use Devolo’s Cockpit app, the web interface or firmware updater software from Devolo.

Cockpit App

I have a four adaptor setup at home, with a pair of dLAN 1200+ units and a couple of older 500 and 200 dLAN adaptors. I used the Windows Cockpit app and simply hit “Updates”. The Cockpit software detected that a couple of my adaptors needed firmware updates, which it kindly installed automatically.

In addition to the speed boost, the dLAN 1200+ series adaptors display a red LED light to indicate where a poor connection is present. This light had previously been set to trigger at 8 Mb/s but will now trigger at the 20 Mb/s to reflect the increased speed requirements of a modern home. If you don’t like the LEDs, they can be turned off too.

I haven’t tried any LAN speed tests to confirm performance improvements, though Netflix streams as well as it ever did. Go get it.


Smart Home Help from Powerline Networking



Samsung SmartThings LogoNearly all smart home systems have a controlling hub which typically requires a cabled network connection as the hub itself has a number of wireless transmitters such as ZigBee, Z-wave or Bluetooth to control the smart devices round the home.

Given that the best location for the smart hub is in the centre of a house for maximum coverage, this presents difficulties as few properties will have a network point at just the right location. However, there’s a fairly good chance that there will be a power outlet near the location and this can be used for network connectivity using powerline networking aka HomePlug.

The video below shows how I connected up my Samsung SmartThings hub using powerline networking from Devolo.


Take Control with the Netduma R1 Router



British Inventors ProjectThese days it’s not unusual for a household to be consume considerable amounts of bandwidth. Someone can be gaming, someone can be streaming an HD movie and and someone else can be on a video call. Who’s hogging the broadband? Who takes priority? The Netduma R1 router answers these questions and takes control back with easy-to-use software for gamers and demanding families.

Netduma R1

On show at the Gadget Show Live as part of the British Inventors’ Project, the Netduma R1 sits between the cable modem and the rest of the network. It provides a raft of features for gamers including geo-filtering, anti-flood, player & server denial and ping stats. For bandwidth hogging households, there’s graphical network monitoring and device prioritisation. Everything can be done via web-based interface and no technical knowledge is needed; to prioritise one device over another, simply drag the device out.

Netduma Control Software

Speaking to the Netduma team after the interview, I was impressed at what they have managed to achieve. I’m not a gamer but some of their plans for family-friendly enhancements sounded really interesting. Priced at £149 / $199 it’s not cheap but for gamers it’s definitely worth having a look.


Devolo dLAN 1200+ WiFi ac Starter Kit Review



Devolo Logo

I’m a big fan of powerline networking and Devolo in particular because it helped me double the speed of my internet connection. It was simple; using one of their adaptors I was able to put my broadband router by my telephone master socket rather than at the end of a long extension lead. In one go, my download speed jumped from around 4 Mb/s to over 8 Mb/s. Result.

Obviously these speeds are trivial in comparison with data transfer rates achieved by gigabit networking and the limiting factor is the internet connection, but where a media enthusiast has set up a DLNA server in a house with multiple playback devices – smartphones, tablets, media streamers, smart TVs, games consoles – significantly higher data rates are needed and this is where the Devolo dLAN 1200+ WiFi ac Starter kit is likely to come in handy. Let’s take a look…

Devolo 1200+

For those who haven’t come across powerline networking before, it’s a way of using a home’s electricity sockets as a network infrastructure. A minimum of two network adaptors are required; plug one into a power socket near the router and connect with a network cable. Plug the other into a power socket near, say, your smart TV, and again connect via network cable. The two adaptors then communicate across the electrical network, connecting the smart TV to the router. It’s that easy.

Opening the box (courtesy of Devolo), there are two network adaptors, two network cables and a getting started guide. As can be seen from the picture, the adaptors aren’t small, but they do have power pass-thru, so there’s no loss of a power socket. Somewhat oddly the bulk of the adaptor points upwards, whereas the older adaptors tend to point downwards and were more discreet. These units are for the UK market, with different plug configurations available for other countries.

Devolo dLAN 1200

Devolo Hard to ReachBoth of the adaptors come with gigabit ethernet ports; there’s one on the smaller unit and two on the larger. The larger network adaptor takes the usefulness of powerline networking a step further with the incorporation of a wifi access point. It’s not just any old wifi either. It’s an 802.11ac implementation meaning that it broadcasts on both 2.4 GHz and 5 GHz, supporting data rates of up to 1200 Mb/s, which is broadly “state of the art” as it stands.

On the box, Devolo helpfully points out some of the areas where ordinary wifi coverage may be less than ideal, including the smallest room. It gave me a chuckle.

Devolo 1200+ Network Ports

Devolo Adaptor AddGetting going with the Devolo dLAN 1200+ is easy. As these adaptors come pre-paired out of the box, all that needs to be done is plug them in and connect up. The LED “house” light on the larger unit will flash red until connection is made and then go solid white – perhaps taking 20 seconds. Introducing the adaptors into an existing network is straightforward as Devolo has great software that helps with this too.

Devolo provides three ways of interacting with the dLAN adaptors. First, there’s a desktop version of their Cockpit software for Windows, Mac and Ubuntu Linux.

Devolo Cockpit PC

Second, there’s an app for iOS and Android. There are currently two apps for Android, Cockpit and My Devolo, both of which do much the same in terms of the dLAN adaptors, but My Devolo appears to be the newer. The screen shots are from Cockpit.

Finally, there’s a web interface.

The impressive part about the dLAN1200+ WiFi adaptor is that it isn’t just a wifi extender: it’s effectively a fully featured router with DHCP, access control, parental control and guest setup, along with everything else needed to configure the wifi. If the non-wifi dLAN 1200+ adaptor was connected to a pure cable or broadband modem, there would be no need for any other equipment. Very neat.

Devolo Web

Performance-wise, the Devolo dLAN 1200+ seemed both fast and solid. For over a month, I used the dLAN 1200+ WiFi supplied network services for most of the devices in my house, including smartphones, tablets, ereaders, laptops, a Chromebook, Sky+ TV on-demand, and two Roku media streamers. No problems to report with connectivity or stability. In terms of speed, I was able to stream three different HD movies to three tablets at the same time without any glitching or stuttering.

In closing, there are two features of Devolo’s products that I think set it apart from the cheaper end of the market. First, there’s great backwards compatibility with older products; I was able to use three generations of Devolo products in the one network. Second, their comprehensive management software which is available as an app, application and web service.

Overall, the Devolo 1200+ WiFi ac Starter Kit is excellent. The devices themselves are well-made, though perhaps on the large side but it’s a great setup for those where the the living room is far away from the main router. There are two gigabit sockets on the adaptor for any equipment that doesn’t have wireless, plus fast WiFi for those devices that do. With the option of using the 5 GHz frequency for congested areas or to spread the load, the wireless performance is great.

The Devolo 1200+ WiFi ac Starter Kit is available online at around £160, which isn’t cheap but considering what comes in the box, plus the performance and the benefit of getting wifi where you need it, I think it’s value for money.

Thanks to Devolo for the review unit.


D-Link AC3200 Ultra Wi-Fi Router



D-Link LogoWith wifi routers and access points, there’s a subtle game of one-upmanship based on the number of aerials sprouting from the device. If unit has only one aerial or it’s embedded in the unit, it probably comes free from the broadband or cable provider; two aerials is soooo 11g, three aerials and the router’s got some chops; six aerials….now you’re getting serious. Todd gets up to speed with the AC3200 Ultra Wi-Fi router from Daniel Kelley, VP at D-Link.

The AC3200 is a serious piece of kit. To start with, it looks like something straight out of a sci-film, a red stealth fighter fully armed with six laser cannon. And while the laser cannon are really aerials, you get the point – it means business. The AC3200 is a tri-band router using one set of frequencies in the 2.4 GHz range and two sets in the 5 GHz. It intelligently assesses the bandwidth and QoS (Quality of Service) demands of the connecting devices and allocates them to the most appropriate channels, and if necessary, can aggregate all three bands giving a maximum theoretical transfer rate of 3.2 Gb/s. No matter that the actual data rate will be much lower, it’s still screaming fast.

Additionally, the AC3200 uses beam-forming technology to focus the wifi signal to where it’s needed, rather than transmitting uniformly everywhere. On the wired side, there are four gigabit ethernet ports and two USB ports (one USB3, one USB2) for connecting up storage (DLNA server built-in) or printers. The AC3200 can be the hub of a connected home.

The AC3200 Ultra Wi-Fi Router (aka DIR-890L/R) is available now on-line for around $300. It’s pricey, but you get what you pay for.

Devolo Launches Gigabit Powerline with 11ac WiFi



Devolo LogoPowerline networking is a great way to spread data connectivity around a home via electrical sockets instead of Ethernet, and today Devolo announced the UK availability of its first gigabit Powerline adaptor with built-in 11ac WiFi: the dLAN 1200+ WiFi ac. The gigabit speeds make it perfect for households that stream 4K and 3D content to multiple wired and wireless devices.

At 1200 Mb/s, the dLAN 1200+ more than doubles the speed of the previous generation 500 Mb/s Devolo dLAN WiFi adapters. The new high speed adaptor features two gigabit Ethernet ports allowing users to hardwire multiple devices to one unit, from games consoles to NAS home servers, while the adaptor is also a wireless access point for laptops, tablets and smartphones.

Borrowing techniques from the wireless industry, the gigabit speeds are achieved using MIMO technology (Multiple Input Multiple Output) which simultaneously uses the live, neutral and earth connectors in the electrical cable. On the WiFi side, the dLAN adaptor uses both the 2.4 GHz and 5 GHz frequencies which is great if the lower frequency channels are busy. Transmission rates are 300 Mb/s on the 2.4 GHz band and 867 Mb/s on 5 GHz.

Devolo dLAN 1200 plus WiFi ac_productpicture_classic_sgl_uk_print_01

Heiko Harbers, CEO of devolo AG said:  “We have launched the dLAN 1200 WiFi ac to accommodate the multiple internet compatible devices people have in their homes today, and in response to the increasingly widespread availability of superfast broadband. All connected devices can now work to their full potential regardless of where they are located in the house. We placed particular emphasis on easy installation when designing the 1200 WiFi ac including the ability to establish a WiFi connection at the push of a button.

The dLAN 1200+ WiFi ac is fully compatible with previous Devolo products from the dLAN 200 onwards and all Powerline adapters that comply with the HomePlug AV(2) standard.

Available now, the dLAN 1200+ WiFi ac is available to order online with a starter kit priced at GB£159.99. A single dLAN 1200+ WiFi ac adapter to expand an existing dLAN Powerline network costs GB£109.99 RRP.


Logstalgia Shows Server Traffic As Pong



Server traffic is a crucial element of the Internet but it’s pretty dull and hard to make interesting…unless you have Logstalgia (aka ApachePong) by Andrew Caudwell. It’s a “website traffic visualization that replays or streams web-server access logs as a pong-like battle between the web server and an never ending torrent of requests. Requests appear as colored balls (the same color as the host) which travel across the screen to arrive at the requested location. Successful requests are hit by the paddle while unsuccessful ones (eg 404 – File Not Found) are missed and pass through.

Here’s what boring web requests can look like….

Todd, you should get this setup for GNC. It would be awesome!


Devolo Develops for 4K



Devolo LogoDevolo today announced their new dLAN 1200+, the fastest Powerline networking adaptor in their range with Gigabit-class data transmission. The latest adaptors double the speed of the dLAN 650 by using a combination of Devolo range+ technology, the newest generation of Powerline chips and MIMO (multiple input, multiple output) technology, offering a maximum of 1200 Mb/s. This is ideal for anyone wanting to stream 4K video but doesn’t have a network point close to their UltraHD TV.

Devolo dLAN 1200+ Powerline Adaptors

With the Powerline adaptors on all the time, Devolo has kept the power consumption low. When in use, the dLAN 1200+ uses a maximum of 4.2 W, and if the connected device, e.g. TV, is switched off, the adapter automatically goes into standby mode, using just 0.7 W. If security is a concern, users can also activate 128-bit AES encryption to avoid any unauthorised access to the network.

As can be seen from the pictures, the dLAN 1200+ is equipped with a gigabit Ethernet connection and an integrated electrical socket with mains filter.  It’s fully compatible with all previous dLAN models, though the maximum speed will be limited by the slowest adaptor.

The adapters can be purchased as a starter kit for setting up a home network or as individual adapters to extend an existing network. The starter kit is priced at GB£119.99, while the single adapter costs GB£64.99. Devolo will be officially unveiling this new range of products at the IFA Conference in Berlin from 5th-10th September.

Hmm, these might be my next upgrade – hopefully they’ll be available before Christmas.


Devolo Entering Smart Home Market



Devolo LogoPowerline networking experts devolo have announced their intention to enter the smarthome market with a comprehensive array of products including movement and smoke detectors, radiator thermostats and switchable power outlets, taking on the likes of Nest and Belkin. Branded as “Home Control”, the products will be debuted at this year’s IFA show in Berlin in September.

Focused on providing customers with greater convenience, security and energy efficiency through innovative smart home products, devolo Home Control is the first smart home system that you can build yourself. Whether it’s a coffee machine that automatically starts ten minutes before breakfast, a switch that sets the entire house to night mode, or a motion detector that can tell people from pets, the possibilities for creating a smart home are endless.”

Devolo Powerline Data Rates“Simplicity is the promise of devolo Home Control with an easy installation process removing the need for tools or cables, and a range of components that can be combined as desired. Taking example from their successful Powerline ranges, Home Control products will be available in helpful starter kits, with the ability to expand and tailor the smart home through individual products.

I run devolo Powerline at home and while their gear is more expensive than the equivalent from Belkin or TP-Link, it’s very reliable and I’ve never had to reset any of the adaptors. In addition, the complementary “Cockpit” software and app is much easier to use and runs on both my PC and my tablet. Amongst other features, the app shows the data transfer rates between the paired adaptors and makes adding in new adaptors very simple. Going back to the new Home Control, the press release mentions that the Home Control products will have a “My Devolo” and if they can keep it simple with a cool app, I think devolo will have a winner on their hands.

Interestingly, what isn’t mentioned is whether the Home Control devices will use Powerline, ZigBee (or Wi-Fi) for the controlling signals. I have problems with ZigBee and the solid walls of my house, so a Powerline-based system could be a huge advantage. I’ll be very interested to see what comes out of devolo at IFA.
