Ok , Papa Tita, thanks for your strong support !
I thought the MagicPowerv5.0 , also was applying the patch in the rcS file , but I did not see any implementation there, and still "GB" inside.... (but as you said, your patch did not modify the rcS.)
Anyway , after magicpower 5.0 , iwinfo , shows correctly 24 dBm in both AC, RC, but before the change I had a maximum range of 220m, and now 350 m, (good, but very far away from your forum results) (but always with perfect video link ) . Therefore I wonder , if the 5,8Ghz path is still limitted due to CE .or BO country .
When checking the reg setting , it answers,
country BO

FS-JP
(2402-2482 @ 40) , (N/A , 30, (N/A)
(5735-5835 @ 80), (N/A, 30, (N/A)
Please advise me , if I can do anything more to increase some dB's the 5,8Ghz.
Should I revert back to stock and apply the new magicpower 5.1 ?
