[ubuntu] SOLVED problem a Problem again :(

Ok
SO i was facing this issue

HTML Code:

http://ubuntuforums.org/showthread.php?t=2317052

That was solved. Then again, after so many months, I downloaded some system "Recommended Updates" and bam! the coection issue is back again. This time I did't tamper with anything. Neither the Router (Actually bought a new one and set it as per the indicated solution for the above problem).
So I ran the first code here "http://ubuntuforums.org/showthread.php?t=370108" just to make sure everything is updated.
Ran the wireless-info code and saw to it it had the parameter "ant_sel" in it.
Here's the first one

Code:

########## wireless info END ############

Then tested the wifi coection issue and still problem persists. It doesn't coect wirelessly!!!

OK.
So I try the second code from here, "http://askubuntu.com/questions/717685/realtek-wifi-card-rtl8723be-not-working-properly/722904#722904"
except I try the setting "ant_sel=1" (as =2 was already tried and tested). And still the problem persists. Infact it gets worse. Doesn't detect my wifi coection.
So I set to "ant_sel=2" and test it again, and still no relief.
I ran the wireless-info text again and here's the result.

Code:
