wifi adapter not working after upgrade to 11.10
I have been struggling with this and not making any progress and would like some suggestions from the forums knowledgeable about Ubuntu. I read many threads about wifi adapter issues and tried to proactively answer the common questions. I hope that did not make this thread too long.
Issue:
The wireless network adapter worked fine using 11.04.
After upgrading to 11.10, I seem to have no wireless device. The PC shows no signs of searching for a wifi signal. And of course, I have no network connectivity.
I believe I already have what I need. Possibly something is in the wrong location. But it worked on 11.04, so I think I just need to set it up in a way that 11.10 understands. I did try reinstalling the old driver and installing a new driver (notes below). That did not help.
iwconfig shows no wireless devices.
lsusb shows the ASUS device which is plugged into a USB port:
Bus 004 Device 002: ID 058f:9360 Alcor Micro Corp. 8-in-1 Media Card Reader
lspci shows the Realtek driver which is the original driver:
01:0c.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
