capabilities/regulatory prevented using AP HT/VHT configuration

[Luis Alvarado]

The error is similar to this one: http://archlinux.2023198.n4.nabble.com/Re-arch-dev-public-linux-3-8-0-1-wifi-problem-td4684455.html

After 2 to 3 hours, the connection simply drops. Not only that but if I try to look for the AP, it does not show the one I was connected to (but others appear). Or in rare cases for the error, it does not show any AP.

I have read other links suggesting where the problem could be like:

https://patchwork.kernel.org/patch/2117341/

https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?

Using Ubuntu 13.04 64 Bit
Network controller: Ralink corp. RT2800 802.11n PCI

Status changed to 'Confirmed' because the bug affects multiple users.

What's the workaround for this?

Getting the same error on 14.04 with an Intel 7265 connecting to 802.11AC networks:

Hi Christopher, thank you for the feedback. Will take this into account for any future bugs reported. I regret to inform you that the hardware I had at the time I created this ticket (2013) is not available. I moved to new hardware early this year.
