Comment 30 for bug 802902

Christopher M. Penalver,
i would like to ask you, how to call or address problem (if you take a look at comment 28 and this comment below)?

* Power consumption for wg111v3 with current linux driver rtl8187 is inefficient ?

* Need more inefficient power consumption for device wg111v3 ?

* TX Power problem or wrong voltage? (of course it's just fun to think about this: and how to verify it ? :D ..... )

* And usb cable ...... uninterference algorith is wrong or driver (kernel, OS) lacks of it at all?

* Or usb power control in OS is wrong ?

So how to look at situation, which direction to go?

All i can say, that this problem ( chip rtl8187b overheating ) can lead to :

* connection degrades after few minutes or after 30 min
  (all depends how device is dissipating heat at it depends on each situation and moment differently
   and additional cooling really solves problem)

* OS can reports it's "Excellently" connected - but in reality it can't move a byte;

* or connection rate and stability can vary from time to time .

I like this comment from:

Although it has the same chipset, it's the adapter manufacturer who decides which chipset features are actually available to the end user. In any event, leaving TX Power at the default is always the recommended action since increasing it can have negative effects such as:

* overheating of the power amplifier chip and the card which will cause lower efficiency and more data errors;

* overdriving the amplifier which will cause more data errors;

* excessive power usage for the card and this may overload the 3.3V power supply of the board that the card is located on resulting in voltage drop and reboot or excessive temperatures for the board.

* Life-expectancy of the adapter is greatly reduced.
