I am running 64 bit Ubuntu 11.04 - the Natty Narwhal .
I had Linksys WMP54GS (PCI) working fine but recently I acquired TP-Link PCI-E, model TL-WN781ND Ver 2.1, because report said it being supported by Linux. However, it is not the case for me, somehow.
I have searched and searched, even tried rebuilding the kernel but failed to update grub (followed all the instruction but grub does not list newly built kernel).
Here is the output of various probes:

I tried Linux-Secure-12.10 Live CD and it works fine out of the box. This card works under Windows Vista 32 Bit fine.
What am I doing wrong? Any help?
