13b1:002f Cisco Linksys AE1000 rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x0500 with error -71

[Jonathan Brier]

With my USB adapter Linksys AE1000, on the University of Maryland College Park campus I am experiencing wifi connectivity issues where I get an initial connection, but it will drop frequently and have difficulty reconnecting to this secured wifi. This is at multiple locations on campus, but not off campus that I've found at this time. My Android Phone and Tablet do not have wifi issues connecting. It was working for a while until it lost connection. After the loss of connection I saw a repeated:
ieee80211 phy1: rt2x00usb_regbusy_read: Error - Indirect register access failed: offset=0x00000500, value=0xffff8804

ieee80211 phy1: rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x0500 with error -71

Before the wifi connection loss I saw repeated:
ieee80211 phy1: rt2800usb_tx_sta_fifo_read_completed: Warning - TX status read failed -71

[penalvch (penalvch)]

Jonathan Brier, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, Y, and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

[Jonathan Brier (brierjon)]

I ran into the same issue with the latest mainline kernel 4.3.0-040300rc3-generic.

[Jonathan Brier (brierjon)]

Tested again with 4.3.0-040300rv4 issue still present.

[penalvch (penalvch)]

Jonathan Brier, the issue you are reporting is an upstream one. Could you please report this problem following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate venue (linux-wireless CC Stanislaw Gruszka and Helmut Schaa)?

Please provide a direct URL to your newly made report when it becomes available so that it may be tracked.

Thank you for your understanding.

Jonathan Brier, I wanted to clarify that the scope of this report is your Cisco Linksys device, not the built-in WiFi. This is as dealing with each device separately in their own reports is preferred both upstream and downstream. Hence, to scope a different report regarding your built-in WiFi, please file a report about it via a terminal:
ubuntu-bug linux
