I have a HP ENVY dv6 Notebook PC with an AMD A10 quad core and RT3290 wireless. Since I upgraded from Ubuntu 13.04 to 13.10, the wireless connects, but then drops after a few minutes or longer, whether or not I am running openconnect to get through a VPN. If I attempt to run a remote X client (e.g. remote xterm) it drops. If I don't run an X client, it disconnects after a while, requiring a reload of the driver and reconnect.

Wireless info...

sudo lshw -c network
  *-network

I have successfully built and installed the MediaTek driver with no luck on connecting, then the system hangs on reboot and I have to recover/undo the changes to boot successfully.

2013/11/10 update...

I discovered that running a popular speed test on the web is a quick way to get the wireless to disconnect during the upload portion of the test.

Using the aforementioned method to reproduce the problem, I have installed and tested the Linux Kernel 3.12 Release as documented here on my Ubuntu 13.10 system and thus far I have not see the problem with wireless disconnecting again...

Installation of the kernel update on Ubuntu 13.10 with 4 simple commands as documented in Linux Kernel 3.12 Released, Install it in Ubuntu... appears to fix the RT3290 wireless problem for now.

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/linux-headers-3.12.0-031200-generic_3.12.0-031200.201311031935_i386.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/linux-headers-3.12.0-031200_3.12.0-031200.201311031935_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/linux-image-3.12.0-031200-generic_3.12.0-031200.201311031935_i386.deb

sudo dpkg -i linux-headers-3.12.0-*.deb linux-image-3.12.0-*.deb

11/14 Update - Been running for days on the 3.12 kernel and have not had a single wireless problem!
