help with TL-WDN4800 very very slow connection

[kicsrules]

I recently got a TP LINK TL-WDN4800 pcie adapter, the card xfers at most 512Kbps while in a tablet/phone same connection gives me at least what the bandwidth is 20Mbps.

i already tried latest drivers from here http://www.station-drivers.com/index.php/downloads/Drivers/Qualcomm-Atheros/WLan/AR5xxx-9xxxx-Serie/

since tp link drivers are very out of date (already tried them too)

i tested the card with a live version of linux mint and it goes up to 11Mbps at least.. that make me think that the drivers are the issue... but i already tried every driver available for this card :/

my setup is as follows

router FO alcatel lucent i-240w-a current bandwidth 20Mbps - ethernet 1Gbps (which there is a NAS connected)
the wireless setup is automatic (b/g/n) currently the speed that shows connected at is 144Mbps. (if i change the speed just to "n" it goes slower - the other devices are not affected)

windows 7 64bit ultimate SP1

any thoughts ?
