My connection randomly disconnects and prompts me again to input the passphrase for the wifi, I'm typing the password correctly and slowly. It does not connect until I turn off and turn on the Wireless. I'm using WPA personal and my wireless usb is RTL 8187
it seems like it is frequently dropping off the connection when I'm using Transmission bittorrent client, and seldomly if not.
here is the link of my thread on ubuntuforums, which unfortunately no one replied to it.
