It's upsetting that I still get this issue :(

Bug description:
Something odd that I have only seen in Ubuntu, Debian, and derivatives
thereof affects something that most of us use every day, and can be a
real hassle to beginners from what I've noticed: Many USB WiFi drivers
will connect to an access point like usual and after long periods of
inactivity on the network combined with user inactivity on the PC
alone is when this problem appears to arise: The WiFi disconnects and
does not connect again to the same hotspot using the same USB WiFi
dongle unless the computer is restarted or reset, and a lot of the
time, that doesn't immediately stop this error and even if so, the
computer will disconnect yet again not too long from then.
And why does this happen? It puzzles me. Maybe it's the USB chipset
inside the WiFi dongle, or maybe it's a communication error between
the Linux kernel and the automated firewall systems integrated in most
routers and base stations today, it's hard to say. What I know is that
this doesn't just happen on my computer, testing done by myself on
several other computers in different locations using different WiFi
hardware on Ubuntu, Debian, Linux Mint, or derivatives thereof gets
the exact same result as I am experiencing now.
I have gone digging through Debian, Ubuntu, and Linux Mint forums to
try and find the "cure" patch for my computer or router and the answer
as to why this is happening, and the best answer I could find is that
within my system's WiFi Settings, I need to set the BSSID of the
hotspot I am current using as the MAC address of the router which that
hotspot is transmitting.
Upon setting my BSSID to a clone of the Router's MAC address followed
by a system restart, I noticed instant improvement when it comes to
connection reliability, speed, and time to connect, yet after days of
having that MAC as the BSSID, things went back to the usual chaos of
an unreliable connection that no other device within the household has
encountered, not even Android telephones and tablets that use much of
the same underlying Linux code. I performed restarts, updates, more
updates, resets, and even more derivatives of Debian or Ubuntu and
this is still more of an issue than ever.
Via further digging and through a process of trial-and-error, I
enabled the "IPv4 is required for this connection" check box along
with changing the BSSID to a clone of the router's MAC address in
hopes it was a compatibility issue with the "newer" IPv6 Internet
Protocol architecture in an attempt to basically 'force' the machine
to get that digital handshake with the router in a more 'legacy' mode
with IPv4, at least to get some connection. That worked for a bit as
well, but didn't hold up just like before.
I am now sitting here at my computer, still experiencing this issue on
and off, currently having the issue stabilized and stalled at the
moment with the "IPv4 is required for this connection" check box on,
NO BSSID set, NO cloned MAC address, and NO "Restrict to Device"
settings opted-in, hoping this time around this combination of
settings will work, but it's a game of trial-and-error for me at this
point now, like mentioned before.
Has anyone else experienced such terrible connectivity issues only in
Debian-based distributions recently? I have been using Linux for ages
now and I feel as if this issue is now just arising within the past
year, 2014.
A HardInfo report generated from my computer is attached to this bug
report. I hope we can figure out a solution soon to get pushed to all
Debian and Debian-like distros soon! Nobody wants a bad connection.
