[Bug 1586650] Re: Ubuntu 16.04 touchy WiFi Internet
I've run and submitted the requested Apport command. I'm currently on
Ubuntu 14.04.4, and the Internet has been great -- very stable and
It was brought to my attention through my inquiries on Ubuntu Forums
that my WiFi chipset, the AR928X, seems to stop working with newer Linux
kernels. Because I installed Ubuntu 14.04.1, I get the benefit of
staying on kernel 3.13. That's the main reason I don't want to upgrade
anything beyond that kernel.
This person also seemed to think it was kernel-related:

Ubuntu 16.04 touchy WiFi Internet
Status in linux package in Ubuntu:
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.
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.
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
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
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.
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)

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.)
