Why you should avoid proprietary Wi-Fi dongles | Crave – CNET

My comments

Previously, I had written an article about using HomePlug to connect a TiVo device to your home network if you don’t have Ethernet connectivity near the TiVo device. This was after I had seen poor Wi-Fi performance from the TiVo-specified 802.11g Wi-Fi adaptor that a TiVo that was on show at a consumer-electronics show was connected to. This is infact the beginning of a trend by consumer-electronics manufacturers to differentiate their product ranges.

What does it mean if consumer-electronics is “Wi-Fi-ready”

Consumer-electronics manufacturers will place a range of network-enabled consumer-electronics products like flatscreen TVs or Blu-Ray players as “Wi-Fi-ready” or “Wi-Fi-enabled” units. These units will be cheaper than the products that have Wi-Fi functionality integrated in them and this fact is used as a way of differentiating between particular models or ranges.

When you want to use the “Wi-Fi-ready” TV or Blu-Ray player on your home network’s Wi-Fi segment, you have to buy a special Wi-Fi network-adaptor module from the consumer-electronics manufacturer through their retail front. Most such adaptor modules will come in the form of a USB “dongle” that plugs in to a specified USB socket on the device but some manufacturers may require that their technicians install the module in the set for you. This latter practice may be more so with TVs sold by some European manufacturers who are used to having add-on functionality modules available for installation by their technicians at a later date upon their customers’ request.

Of course, nearly all of these items of consumer electronics will have an Ethernet socket on them so you can connect them to an Ethernet network segment or a HomePlug networks segment with the appropriate bridge device.

The Wi-Fi dongles or modules

The dongles or modules are usually peculiar to a manufacturer’s products or may only work with a certain subset of their products such as those that are based on a particular design. They usually cost more than a USB-Wi-Fi network adaptor sold for general-purpose computers. As well, the modules, especially the dongles, may not give the same kind of Wi-Fi performance as a setup where the Wi-Fi functionality is integrated in the device.

It may also be worth paying attention to the price difference for the model that comes with Wi-Fi and the model that is “Wi-Fi-ready”. If the device of concern is a TV set, I would suggest that you compare the two models that have the same screen size and display technology. It is also worth asking if the retailer does sell the Wi-Fi module and how much for. This is because in some cases, the aforementioned price difference at the store may be less than the cost of buying this module.

What can you do with a “Wi-Fi-ready” device if you don’t have Ethernet at its location?

This same situation can also hold true if you wish to go for the cheaper “Wi-Fi-ready” model yet integrate it in to the home network in a “no-new-wires” manner.

I would suggest that you use a HomePlug AV setup to connect the “Wi-Fi-ready” device to the home network if you don’t have an Ethernet connection in place at the device’s location. This also includes situations where you may move the device to a newer location such as “pushing” the existing Internet-enabled “Wi-Fi-ready” TV to the secondary lounge area or bedroom.

Most of the HomePlug AV starter kits which comprise of two HomePlug AV-Ethernet bridges (a.k.a “homeplugs”) can typically cost the same as the add-on Wi-Fi adaptors. It is also worth knowing that if you pay a bit more, some of these kits even come with an integrated Ethernet switch which may be useful if you have two or three network-enabled video peripherals near the TV or are likely to connect the PS3 or Xbox 360 to the TV.

One situation that I would fear most with consumer-electronics would be to use the optional Wi-Fi module technique used in the current crop of “Wi-Fi-ready” equipment to provide network / Internet connectivity to cheaper equipment at extra cost to the consumer.

Here, the equipment would have no Ethernet socket yet still show “network-function” teasers in its user interface and describe the functions in its user manual and marketing literature. But the user would have to buy a Wi-Fi or Ethernet module in order to link the device to the  home network before they benefit from network and Internet functionality.

Like with the Wi-Fi-ready scenario, the user wouldn’t be able to use cheaper or better-value hardware to network-enable their device, therefore end up paying the premium for network connectivity.

Today, I had seen some excellent YouTube videos posted by Netgear on how to integrate your games console in to your home network. They make references to the networks being based on their own hardware, but these instructions apply to any and all home networks no matter what router is at the edge.

Also, when they discussed how to connect the XBox360, PlayStation 3 and Wii to the home network, they mentioned that you can use a HomePlug-based power-line network setup using their PowerLine AV network kit to build the HomePlug segment. The main theme was to connect the HomePlug adaptor to the console via its Ethernet port and select the “wired” connection option as appropriate.

The reason I have liked the videos was because they gave a visual walkthrough of the setup user interaction needed to be performed at each console. They also pointed out if a console needed extra hardware to be part of the home network depending on the connection type. They are also worth having as a reference if you are likely to move your console(s) between locations such as for video-games parties.

My Comments on this Web-enabled printer

When I first read about Hewlett-Packard’s Web-connected printer in this article, I thought that the idea may not be real but they have followed the same path as the recent crop of Web-enabled TVs and the smartphones that are part of most currently-running mobile-phone service contracts. This all-in-one printer could be the start of another development arena for these devices, allowing for a new scope of applications that are “printer-based”. These could include “print-on-demand” like the initial offerings from Google (calendars), Web Sudoku (sudoku puzzles) and DreamWorks Animation (colouring-in sheets) and extend to such applications as image-upload interface points for photo-sharing / social-networking sites and online file storage services.

If this idea pulls off for printers and “all-in-one” devices, then it could lead to other devices that are capable of working with the home network being able to work with the Web and the home network in a manner beyond their obvious design. For this to be achievable, the devices would have to work on platforms like the Windows CE / Windows Mobile platform, the Symbian S-series or UIQ platforms or the Android platform and allow an easy yet secure way of installing the software.

Cite from press release

Over the past few weeks, a couple of announcements around consumer electronics connectivity have caught my eye. In late April, the DiiVA Interactive TV standard was announced after a year of development, with the backing of mainstream CE manufacturers LG, Panasonic, and Samsung, along with the Chinese government and a number of major Chinese CE manufacturers. The DiiVA standard was designed to integrate HD Video, multi-channel audio and bi-directional data (Ethernet and USB) in a single cable. Then, just last week, the HDMI Licensing group announced the HDMI 1.4 specification, which will integrate Ethernet connectivity within the HDMI cable.

My Comments on this concept

The concept behind the DiiVA stamdard and HDMI 1.4 is to cut down the “spaghetti junction” that exists behind a home-entertainment system by avoiding the need to run an Ethernet cable between each Internet-enabled AV device and the home network.

The current problem is that most Internet-enabled equipment that is in the field will require use of a direct network connection, typically an Ethernet cable, even if the AV setup includes equipment that has the new connections. As the standards gain traction, users will have to work out which component will be the interface to the home network; and some equipment will need to always have a direct connection to the home network as well as support for Ethernet connection via the new standards.

When the standard reaches momentum, I would still prefer that certain classes of equipment always have an Ethernet socket or MoCA/HomePlug AV interface. Primarily, I would require that a television set (with built-in TV tuner); and a surround-sound receiver would have the home-network interface. Similarly, I would require that devices performing the role of a surround-sound receiver like “home theatre in box” systems and single-piece “soundbars” be equipped with the home network connectivity. This is typically to allow one to assure network connectivity to all consume AV-equipment setups that use these connections, as these setups evolve. Some AV peripherals like optical-disc players or games consoles may just rely on their network connectivity coming via the AV connection.

Another factor that needs to be worked out with this connection setup is making sure that the network-enabled AV setup just works. Issues that can impede this ideal could include “network collision loops” where devices that are directly connected to the home network and are interconnected with network-enabled connections create an infinite data loop. This can lead to extensive operational and performance difficulties, similar to when a laptop is connected to a WiFi router with an Ethernet cable while its WiFi network functionality is active. This issue could be addressed by the use of a priority-based algorithm for determining the data flow in the AV setup.

Once these issues are addressed, these connection standards should then lead to trouble-free network-enabled home AV for all setups no matter how sophisticated they are. Similarly, this could lead to such concepts as the AV devices providing extra network services such as in-fill WiFi access points or Ethernet switches.
