I am using lucid lynx with this USB adapter and drivers rtl8187.

When I start a download, it starts at 1500kpbs (if i use "iwconfig wlan0 rate [more than 11MB]" it starts at a lower speed), it transfers a few kbs but then the speed starts to drop constantly and nothing is being transferred.

I've also tried the driver r8187, but I have the same speed problem only that with this driver the download starts at only 10kbps, and drops from there.

What can I try to identify the cause and fix this problem?
