After installing namib linux wireless/wifi adapter not detected.
Running 'lspci -k' gave me following output:

After researching a bit on how to install a driver manually, and eventually finding the driver, came across a post that talked about updating kernel before installing driver:
https://bbs.archlinux.org/viewtopic.php?pid=1892926#p1892926
So, I figured I, do that first.
Updated kernal using:sudo pacman -Syu
Several prompts come up. I selected default 'Y'. The last question was about a Perl Conflict. For that, first I selected the default. Then the update exited. Ran the above command again, then for the Perl conflict question selected the non default value. Update ran for about 10 minutes.
Rebooted. Wifi now available.
BTW, while the kernal update was running, I noticed there was some messages to do with 'broadcom'. Wonder if this was what was preventing proper wifi driver loading in the first place.
