If you have used the Alfa AWUS036H 500mW max output wireless USB adapter before, you know it is an awesome WiFi adapter. The range is amazing, and it really does a lot better job than most all other products on the market.
Alfa is a great brand, and they have recently announced that the new AWUS036H models are now 1000mW max output. We received the first shipment of these 1000mW max units from Alfa today, and can confirm the retail box is different. But there are no markings on the box to indicated it is now 1000mW (30 dBm), and the adapter is physically identical to the older version in all aspects. The CD inside the box has a manual which still refers to 27 dBm max output, apparently they forgot to change the manual. They have changed their official web page for this model though.
We asked Alfa, and they have confirmed the units are 1000mW. Alfa is a great company that has long made excellent networking items and we have no doubt that these units are in fact now capable of 1000mW. But Alfa does not have a US-based operation and may not understand that US buyers are constantly faced with ads and products that have inaccurate specs. We have encouraged Alfa to fix their manuals to properly show the new version as 1000mW, and to also add the output specs to the retail box itself. Until they do, we will continue to advertise the model AWUS036H as 500mW max. Note that other retailers have chosen to advertise the same units as 1000mW, but if you buy from Rokland you will be getting the same item.
