Increasing WLAN adapter capability

July 27, 2011 at 13:01:05
Specs: Windows 7 64 bit, 2 GB
I would like to know exactly what

PDCAP_D3_SUPPORTED

means, its under "power data" in the details of my Atheros AR9285 Wireless network adapter. Is there perhaps a way to increase the amount of power going to my Network adapter?

the whole page looks like this:
__________________________________________
Current power state:
D0

Power capabilities:
000000BB
PDCAP_D0_SUPPORTED
PDCAP_D1_SUPPORTED
PDCAP_D3_SUPPORTED
PDCAP_WAKE_FROM_D0_SUPPORTED
PDCAP_WAKE_FROM_D1_SUPPORTED
PDCAP_WAKE_FROM_D3_SUPPORTED

Power state mappings:
S0 -> D0
S1 -> Unspecified
S2 -> Unspecified
S3 -> D3
S4 -> D3
S5 -> D3

_____________________________________

it seems as though my newtork adapter is set in power state "D0" ... I have an incredibly slow internet connection and am looking for any possible way to increase the speed of this connection, I've seen alot of forums posts that state

- increasing the power to the network card,
- increasing the power to the actual Router Antenna and
-changing the Power mode on my laptop from "saver" to "high performance"

help to improve Wireless Network Card Adapter performance. I have updated al the drivers and firmware for my Wireless router and Adapter.

Thanks in advance ...

*note
I would obviously prefer to be connected with a wired connection, but from where I am it's not possible all the time.

I'm sorry but none of the following will increase bandwidth capabilities:

- increasing the power to the network card,
- increasing the power to the actual Router Antenna and
-changing the Power mode on my laptop from "saver" to "high performance"

which is what I believe you're asking for when you say, " have an incredibly slow internet connection and am looking for any possible way to increase the speed of this connection"

Truth be told, there is only one way to increase your bandwidth and that's to get a higher bandwidth package from your ISP. If the offer packages with more bandwidth.

If your network interface is working properly it's already doing it's best and the bandwidth issues you're experiencing are likely because:
- wireless is inherently susceptible to lag and latency
- your ISP oversubscribes their network segments and you have too many people on the same one as you
- you're sharing your network segment with people who run point-to-point sharing software and deal in illegal file up/downloads. Up/downloading, especially the 24/7 type, is very bandwidth intensive and can and will suck up all available bandwidth to the detriment of everybody else on the same network.

The only other thing I can think of that's the issue would be the modem as provided by your ISP. You could definitely be experiencing a hardware issue that isn't your network interface or the computer it's attached to.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

All those setting relate to power savings specifically PDCAP_WAKE_FROM_D0_SUPPORTED means that the device can wake the computer from a Sleep state.

None of it has anything to do with the RF power output of the wireless. That is fixed by regulation and there is nothing the user can do to change it except make better use of the power that is available and that means a hi-gain antenna.

Thanks for the quick replies ...

I figured that out eventually after sifting through quite a few posts and some other forums. I did also see someone else post something about increasing or decreasing the size of the *"packets" (if I'm not mistaken) so that the signal is not so fragmented between you and the router. Anyways, I guess I'm just going to have to stick it out with African Interwebzzzzz.

thanks again :)
