Regarding bell-curve txpower, I've seen the same results on other devices, the one I worked most with was the Asus WL-500g AP (busybox). I performed dBm tests and it showed a power dropoff above a certain point. I then worked on other parameters, IIRC there seemed to be an automatic gain limiter or some such in action which could be modified also.
Previous poster mentioned this. I noticed there's a significant grounding/earthing problem with the Alfa. Touching the SMA metal collar "undeafens" the NIC. Often few AP's are picked up unless resting a finger on the metal collar. Can anyone else confirm this issue?
Further, Kismet (bt3final) misses many AP's unless channel dwell time is lengthened. Confirmation?
ok do you have your adapter hooked up with one usb port or two i just got mine and it came with the single usb cable i installed the drivers and patch from aircrack-ng.org and im getting low power even when i put the power leavel up to 15 im not real sure what is going on here but i think i need to have the usb cable with 2 male ends
On the original Alfa, the two cable connections are needed only when you are operating on battery power.....so, you are probably ok there.
When you say you only get low power, how do you know that? What does iwconfig say for your dbm?
The "power" reading or capability is ONLY for the transmit side so you may not see any improvement in number of APs that are visable.
BUT, if you see the AP, the higher transmit power may be the final factor that allows you to interact with the AP.
Finally, on a French 036 site, they did some very detailed analysis of the power but found a high sensitivity in the actual numbers....based on the exact positioning of the power meter (in order to make a valid comparison with other wireless cards)
Can anyone tell me why the txpower of the new rtl8187 in bt4pre can't go beyond 20? It used to go up to 27 for Alfa 500mW.
EDIT: I think I know why.
I have the card in me head, but you have the memory problems?
Alfa AWUS036H, BT 3:
iwpriv wlan0 highpower 1
iwconfig wlan0 txpower 35
Very good thread ... it helped me too much
[QUOTE=msenoz;159806]Has anybody found the utility in the video which has many extra tweaking features for 8187L chip, if yes can you please advise the link to download and try.
i can't post links but search for "RTL8187L UI Package and driver" on realtek homepage.
i'm not 100% sure if it's the tool in the vid since i can't test it coz it's only for m$ windoze and i'm using ubuntu but it has the same name
