Unable to find an existing Wifi cell on both 13.10 and 14.04

Asked by vr

I had this problem on both 13.10 and 14.04. I am using 14.04 currently.
There's a wifi cell just next room with essid "Arkham-net".
I could connect with it initially. But sometimes when the modem restarts,
my wifi connection breaks as expected, with a notification saying "disconnected".
But it does not reconnect nor list the "Arkham-net" cell in the available
connections there after.

There are other wifi devices connecting to the same cell "Arkham-net" with no issues.
I dont understand why this wifi connection is not detected in my OS. I could connect
and disconnect on 12.04 any number of times. Its just when I freshly-installed 13.10 and
now 14.04 that this problem is coming up. I stopped using 13.10 in February after this problem
and waited till 14.04 hoping the problem would be fixed.

There was an issue with broadcom wireless drivers in 13.10.
That was resolved in 14.04 with "wl" driver. I found it already activated in the
additional drivers list. I used wifi on 14.04 twice today. But now the connection is not detected.

I checked the wifi connection on my samsung galaxy phone with an app called "wifi analyzer".
I could browse the net on my phone, it works fine, I mean there is problem at the modem end I believe.
No other wifi devices using the connection have experience this problem.

I have run a set of commands before and after the problem, I am posting their output below.
Kindly help me figure out this problem. I have used long line of stars(****) to show the differences in the
output before and after. Other commands produce the same output.

I use Dell Inspiron 1525 laptop.

Can someone please respond, I have tried the following cmd:
echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf > /dev/null

but it did not solve the problem. I dont understand why I can view other wifi networks
but not the one I was connected to earlier. It just disappeared but the modem is actually on
and other devices are connected to it(my phone). I rechecked the modem settings if any MAC address
is blocked or something. Didn't find anything fishy there.

I did grep 'etwork' on /var/log/syslog, I got this:

Apr 21 23:08:12 archangel NetworkManager[722]: <info> (wlan0): bringing up device.
Apr 21 23:08:12 archangel NetworkManager[722]: <info> (wlan0): preparing device.
