I am trying to use the AWUS036H wifi adapter which I have used on older versions of ubuntu without problem. But now using 12.04.2 I am having problems, i connect the adapter and I use "modprobe rtl8187" to load the drivers, then I can see wlan0 with iwconfig, then i tried to connect to a wifi network using the network-manager-gnome gui, and I noticed the "Wireless" section disappeared and reappeared, so I checked dmesg and this is whats shown exactly then the wlan0 disappears and reappears

[ 1208.044663] ADDRCONF(NETDEV_UP): wlan0: link is not ready <- STILL WORKING
[ 1286.188003] usb 1-1.3: USB disconnect, device number 112 <- DISAPPEARS
[ 1286.476739] usb 1-1.3: new high-speed USB device number 113 using ehci_hcd <- WORKING AGAIN

Here's the full log http://pastebin.com/raw.php?i=ZXQM0L6G it repeats the same stuff as long as the usb wifi adapter stay connected.

Anyone knows whats going on and how to solve it? UPDATE:

Let me know the pci id of the adapter by using lsusb -v | grep 10ec, seems like it's a realtek chip. –  grimpitch Apr 26 '13 at 3:55
    
@grimpitch question updated with lsusb output. This same adapter work perfectly fine in ubuntu 11. –  peterfra Apr 26 '13 at 4:10
