N, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically
requested to do so.

Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.

Thank you for your understanding.

** Description changed:

- I just recently did a fresh install of Ubuntu 16.04 on my desktop last
- weekend, and since that time my household had to reconfigure our modem
- and router setup (from bridge mode to DHCP mode). As a result, I lost
- all ability on my computer to connect to WiFi or the Internet. This
- isn't the first time this has happened on an Ubuntu version.
+ When I installed Ubuntu 16.04 I had to reconfigure our modem and router
+ setup from bridge mode to DHCP mode. As a result, I lost all ability on
+ my computer to connect to WiFi.

- However, all other devices in my household (there are over eight other
- devices between my family members), including my iPad and my
- PlayStation, had Internet connection. Growing desperate, I
- troubleshooted for days, trying out multiple solutions posted on
- AskUbuntu.com. I even opened up two AskUbuntu.com questions, and some
- people helped me troubleshoot the issue for a while. But eventually they
- gave up and left me alone with my problem.
+ However, the other eight connected devices (ex. iPad, PlayStation) have
+ Internet connection.

- I felt so frustrated and exasperated. I thought I was never going to get
- Internet on my desktop again. Or that I would have to completely
- reinstall Ubuntu 16.04, because some old settings had been imprinted on
- my file system or something. But I can't be reinstalling my OS every
- time someone in my house alters something on our modem or router.
-
- Finally, this morning, I decided I would try one last thing: power-
- cycling our router and modem. I was very reluctant to do this, because
- the Internet had at last been working great for everyone in our house
- (we'd been having chronic Internet problems over the previous months),
- and I didn't want to compromise that. But I really need to have Internet
- on my desktop. So I power-cycled our router and modem, and finally,
- FINALLY my Internet works on my computer. It is a bit slow (only 2 Mbps
- download speed, and web pages load up slowly), but it actually works.
- I'm of course very skeptical that it will stop working at any time, but
- for now, it's functional.
-
- The issue I have with Ubuntu is that the networking seems extremely
- touchy and fragile, and isn't very resilient when something changes on
- your home network. My iPad doesn't have that problem at all; it will
- reconnect to any router within seconds, and you'll be back on the
- Internet in no time. My PlayStation can reestablish a new connection
- profile pretty much automatically and get you back gaming online within
- minutes. It's with Ubuntu, or Linux, that I've repeatedly encountered
- this debilitating issue, where reconnecting to an altered network is
- such a precarious thing.
-
- I'd really, REALLY like to continue using Ubuntu. For at least a few
- years, I no longer have Windows on my machine, I game heavily on Steam
- for Linux, and I really need the Internet on my desktop for work and for
- pleasure. But if I can't get Internet reliably with Linux, I fear I'm
- going to have to switch to another OS. And that would be a real shame.
-
- Please, improve the WiFi networking on Ubuntu so that it is just as
- snappy and resilient as my iPad, and I will be a very happy Ubuntu user
- for years to come.
-
- Thank you for reading.
+ After power-cycling our router and modem I'm now able to connect but I
+ get 2 Mbps download speed, and web pages load up slowly.

My system specifications:
Ubuntu 16.04 LTS (64-bit)
Asus M4A78LT-M LE Motherboard
AMD Athlon II X4 645, 3.10 GHz
Mushkin 8 GB PC3 Blackline RAM (2 x 4 GB)
500 GB Hard Disk
Qualcomm Atheros AR928X Wireless Network Adapter (PCI-Express)
Nvidia GeForce GTX 750 Ti

(* I bought the Qualcomm Atheros AR928X Wireless Network Adapter specifically to work with Ubuntu from a Linux-friendly retailer. It normally works great, and no matter what it always at least shows WiFi signals nearby, even if I can't connect to them.)
