Nice review dude.

Thanks. I hope one of the mods can change the title from [WIP] to [REVIEWED] though...

DM purehate or archangle. They would probably do it. I'm not a mod or I'd do it.

Noone has expressed a concern on the lack of power that a usb port provides for such a powerful wifi adapter. I know there were concerns for the 1000mW, so wouldn't the 2000mW adapter have to consume even more power that it probably isn't getting. I would like to hear more about this issue.

From wikipedia:

The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V±5%) between the positive and negative bus power lines. For USB 2.0 the voltage supplied by low-powered hub ports is 4.4 V to 5.25 V.[29]

A unit load is defined as 100 mA in USB 2.0, and was raised to 150 mA in USB 3.0. A maximum of 5 unit loads (500 mA) can be drawn from a port in USB 2.0, which was raised to 6 (900 mA) in USB 3.0. There are two types of devices: low-power and high-power. Low-power devices draw at most 1 unit load, with minimum operating voltage of 4.4 V in USB 2.0, and 4 V in USB 3.0. High-power devices draw the maximum number of unit loads supported by the standard. All devices default as low-power but the device's software may request high-power as long as the power is available on the providing bus.[30]

TL:DR: 2.5 Watts maximum draw from a port, should be fine.

Does anyone (Citruspers) have any preference between this card: DealExtreme: $24.10 2000mW High Power 802.11b/g ... Dual High Gain Antenna that you've reviewed here or the very similar looking DealExtreme: $21.07 802.11g 54Mbps High Power 1000mW ... mentioned in this thread?

Thanks

[Xploit]

so is this better then DealExtreme: $21.07 802.11g 54Mbps High Power 1000mW USB 2.0 WiFi Wireless Network Dongle ?

give me advice dude for better injection

[hhmatt]

This looks familiar for a suspiciously low price. It only claims to be 1000mW.

You have my two reviews, and you know more power is better for injection. Looks clear to me.
