[SOLVED]M5-64: I messed up WiFi Setup. Can't connect now.

[elmago]

On a HP Elitebook 8740W laptop I tried to add a USB WiFi adapter (very cheap Realtek 8188E 802.11n) and could not succeed. Had the built-in Intel Centrino WiFi disabled by panel touch switch when I did that.

Now, cannot connect the built-in WiFi anymore to office or home network where it used to connect without problem. Have deleted the extra interface by Network Control/Setup (after root password) but still no luck. When I enable the built-in WiFi by laptop touch switch, the LED blinks as if trying to connect but then within a second or two no more activity. WiFi applet shows both networks (Wire and WiFi) disconnected.

I want to restore the built-in WiFi first before tackling the USB WiFi. The laptop is OK as Win7 can connect using the built-in WiFi.

Here are some of the details of
lspcidrake -v | grep -iE "wlan|wifi|wireless|net"
ifconfig -a
rfkill list all
systemctl status network.service -a
journalctl -ab | grep -iE "fw|firmware|iwl|wifi|wire|80211"
Relevant section of "dmesg" output.
Thanks.

Update:
This morning at work, the laptop connected normally to the office network as if nothing happened. Could have been an issue with the network.
Will verify my home router set up tonight.

[elmago]

Problem solved.
In Office Network:
I really do not know how the problem got fixed all by itself. Maybe something to do with caching inside the office router...

In Home Network:
The reasons:
1. I had the router reset and while re-configuring, entered a spelling mistake in the existing password. Realized that and corrected it in /etc/sysconfig/network-scripts/wireless.d folder -- whichever file had the wrong password, I manually corrected them. But that was not enough!
2. Wrong usage of MCC while configuring network. I was trying to add using "Setup a new network interface...". When I tried with "Network Center", it somehow worked. When it asked for WPA2 password I saw it was still holding onto the wrong password (because the password is stored in two different places and I corrected only one).
3. The Wireless configuration is stored in another place: /etc/wpa_supplicant.conf. This morning I checked up on this file and the last time stamp for update is the time when the home network started working again.
4. I concluded from the following "dmesg" log that authentication had succeeded. So, never suspected the existence of the 2nd copy of the password! A little more description instead of "(Reason: 2)" would have been really helpful.
