This thread seems to be rather stale (9 months) but the bug is
apparently still unresolved?
I have a fresh install of 14.04 on an HP pavillion. My network
controller shows up in lspci as

PCIe Wireless Network Adapter

I'm also on a Thinkpad X220. Seth, have you been able to make any more
progress on this bug?

Title:
Wifi Connection Dropping/Need to reconnect
Dear Seth,
Being a support expert myself, I hate to tell such a thing to a valued
developer but this time I don't think opening a new ticket would be the right
path. So far several people mentioned several different wireless cards and
apparently have similar or exactly matching problems. Of cour
Steve: You have different wireless hardware than the reporter. Please
file a new bug by running 'ubuntu-bug linux' in a terminal. Thanks!

Title:
New installation of 14.04LTS. Ralink RT3060 wireless card. Disconnects
about every 15 minutes. Does not automatically reconnect. Tried
disabling N as others have suggested. No effect. I wrote shell script
that runs every minute as a root cron job that checks the state, and
kicks it into operation
Sorry, I celebrated too soon. Today I had disconnections again. Returning to
the "brcmsmac" driver. It seems that the wpa-supplicant and the wl driver does
not like each other...
When disconnects there is a system tray message that says the wpa-supplicant
lost authentication.

After last kernel update (3.13.0-30-generic) I installed again the
proprietary driver (wl), but this time using a terminal: "sudo apt-get
install kernel-source-bcmwl" and there are already two days the wireless
network does not drop.

Sometimes the connection disconnects and disappears from the list of available
networks in network manager.
Enabling/Disabling "Airplane Mode" from KDE's network manager sometimes helps,
sometimes doesn't.

Two days ago I uninstalled the Broadcom (bcmwl-kernel-source package) driver
and since then using "open source" driver (brcmsmac) the wireless network no
longer drop.
So it seems that this confirms, at least in the case of Broadcom, that the
failure is in the driver.

I get this on both a vostro 3360 laptop and a separate machine with a
Ralink corp. RT2561/RT61 802.11g PC card and motherboard network . I did
think it was something to do with another possible connection being
available but it still happens when you disable that conenction in
network settings.

My suspicions were wrong, I installed and tested the WICD and the same symptoms
occurred, with the difference that the WICD automatically reconnected without
asking me the password for the wireless network.
I'll try to make some more tests, maybe compile the driver downloaded directly
from Broa
I have the same symptom, but with Broadcom wireless card and fresh
install of Kubuntu. Tried also Mint 17, same behavior.

I have two machines. A Thinkpad W701 and a Thinkpad Edge 510. Both with
a Realtek 8192SE adapter.
Installed a fresh Ubuntu 14.04 version 64 bits on both.
The Edge 510 loses the wifi connection time and time again, and loses in
the end the interface connection! The W701 loses the connection just

Update - everything ran fine for an hour, now the problem has returned.
Seems better with Chromium compared to Firefox, but still happening.
Apologies for the confusion.

Not sure if I had the same issue - but is sounds really similar. I have
a fresh install of Ubuntu 14.04 running Firefox 29. My wifi would drop
randomly and I'd need to disable and re-enable the wifi to get a
connection again. I had HTTPS Everywhere installed. Once that was
removed, everything w
Thanks. The data is a little incomplete as some of the wireless frames
don't seem to be passed up from the driver, but what I do see (excessive
amounts of frame retransmissions) seems to indicate that your wireless
adapter has difficulty communicating with the APs. The problems
themselves are proba
Seth, sent log file privately.

Jason: It looks like the problems happen when associating. Sometimes you
get a successful association, but then a short time later wpa_supplicant
tries to roam to another AP and the association with the new AP fails.
Unfortunately the logs don't really tell much about why association
fails.

Did this issue just start happening after a recent update? Was there a
prior Trusty kernel that did not exhibit this bug?
