Sony UWABR100 USB Wi-Fi Adapter: what it fits and how it works

The Sony UWABR100 is a small USB Wi-Fi adapter made for certain Sony televisions and Blu-ray systems. It is an accessory rather than a general-purpose network device: it lets a compatible Sony product join your home wireless network so it can reach online features, without running an Ethernet cable across the room.

What it is for

Sony describes the adapter as a way to access your home wireless network when connected to a Sony Wi-Fi Ready HDTV or Blu-ray Disc theatre system. An internet connection is required for the online services on the television or player. The adapter plugs into a USB port on the Sony device, which then treats it as its wireless network connection.

What it fits

This is the most important point. The listing states that compatibility is limited to Sony's 2010 models, and names these:

• HDTV series: HX900, HX800, EX700, EX308 and EX40B.
• Blu-ray players and systems: BDP-S370, BDP-S470, BDP-S270 and BDV-E370.

Sony says it is compatible with its 2010 TVs and home video products. Models from other years, and other brands, aren't covered by the listing, and a USB Wi-Fi adapter generally needs driver support in the device itself, so it is not a plug-and-play option for a PC or other brand of TV.

Wi-Fi Protected Setup

The adapter supports Wi-Fi Protected Setup (WPS), a feature that simplifies connecting to a router. On a WPS-capable access point, you typically press a button on the router and start the connection on the device, rather than typing a long password. If your router lacks WPS, the device's own menus normally offer manual entry of the network name and password; follow the television's manual.

Network requirements

The listing calls for an 802.11 access point and recommends 802.11n, the wireless standard that offers better speed and range than older versions. Streaming video generally works best with a strong signal, so position matters.

What's in the box

Sony lists the Sony USB Wi-Fi Adapter and a 1.5 m extension cable. The cable lets you move the adapter away from the back of the television or player to a spot with better reception.

Who it suits

It suits owners of one of the listed 2010 Sony models who want wireless access to online features and don't have an Ethernet connection nearby.

What to check before you buy

• Exact model: compare your TV or player's model number to the list above.
• Router: confirm your router supports 802.11 and, ideally, WPS and 802.11n.
• USB port: make sure the device has a free USB port, as the manual describes.
• Placement: use the extension cable to improve signal.
• Security settings: check that your router's encryption mode is one the device supports.
• Alternatives: a wired Ethernet connection is another option if your device has a port.
