In 2017
It seams there's some problem with network-manager and also power
management in the driver.
Workaround:
Don't use network-manager. I'm using trinity, with out network-manager.
I also deactivated power management for wifi, and it works correctly.
sudo nano
sigh, it's still broken.
It still behaves the same way...
** Changed in: network-manager (Ubuntu)

I can confirm that removing network-manager and using plain
wpa_supplicant fixes this problem.

It seems that turning off wlan0 power management can help. I'm
using the following command as a temporary workaround:
sudo iwconfig wlan0 power off
As restoring the kernel/driver does not fix the issue, could the
problem be that NetworkManager incorrectly sets up the interface?

Same here: Removing network-manager and using plain wpa_supplicant
commands lead to perfectly stable wifi.

Update: did some regression testing;
- fallback to 3.14 kernel but using same version of network-manager and wifi
drivers did not solve the issue
- removed network-manager package, and used netctl for managing wifi, and the
problem is gone

Having the same issue here as well (although I'm on Arch with 3.16
kernel). Interestingly, on the same computer running Mint (3.13 kernel),
there is no issue. With 3.16 kernel, RT61PCI works for some minutes,
then disconnects, and unable to reconnect again.
Note: both distro's use version 2.3.0
An other computer is connected through the same wifi extender, and that
too uses Ubuntu 15.04. This computer reports Intel(R) Centrino(R)
Wireless-N 2230 BGN, REV=0xC8. There is no similar error reports in
dmsg on this machine.

Same problem here. Some notes about what happen.
Sorry for not providing complete logs.
This is my notes which is not very readable, not even for me.. :)
The machine has been continuously updated since 13.10.
Updated from 14.04 to 15.04 by going through 14.10.
All done yesterday. Problem
bad news...
even with these commands, the connection is rather unstable...

modprobe -v rt61pci nohwcrypt=y did the job for me...
seems to be quite stable now..
I'm still testing is the connection keeps running.

I made some testing with this problem and I wrote script to enable rt61pci wifi
connection temporarily.:
rmmod -v rt61pci
rmmod -v rt2x00mmio
rmmod -v rt2x00pci
rmmod -v rt2x00lib
sleep 1
modprobe -v rt61pci nohwcrypt=y
After I ran that script is started pinging some random host for awhile
and
I have a device that uses rt61pci and when it manages to connect to a
WiFi network, it stops working after a few seconds only.
Relevant line from lspci:
05:00.0 Network controller: Ralink corp. RT2600 802.11 MIMO
Relevant output from dmesg:
ieee80211 phy0: rt2x00queue_flush_queue: Warning -
Working all good on Ubuntu 14.10 livecd.
Still having those things from dmesg:
ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 0 failed to flush
ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 2 failed to flush
But the thing has stayed connected to a WiFi network for a good
plucky, no need to do a reinstall at this point. What was needed was
information regarding which release did the regression occur between.
Given that the issue didn't occur in Utopic, but did in Vivid, this has
been identified.
