Bug Description

On all of my Ubuntu Desktop 12.10 amd64 systems, the network manager will show the wireless card and networks, but will ask for the network password again after trying to connect.

In the attached logs from an pure Ubuntu Desktop 12.10 amd64 system (Live ISO booted from USB stick),
we can see that it worked once :
[ 123.224546] wlan0: associated

Internet access worked, but after disconnecting manually :
[ 129.742078] wlan0: deauthenticating from 00:17:33:b4:e4:44 by local choice (reason=3)

subsequent tentatives will fail with :
[ 143.300130] wlan0: deauthenticated from 00:17:33:b4:e4:44 (Reason: 15)

With Ubuntu 12.04 64bit live environment it connects only once but subsequent tries fail. I have to unplug then replug the adapter to make it work again.

The following upstream drivers load, but fail to activate the device (LED does not light):
* RTL819xCU_USB_linux_v3.4.2_3727.20120404.zip
* RTL819xCU_USB_linux_v3.4.3_4369.20120622.zip

Attached is the syslog from one of my main Ubuntu Desktop 12.10 amd64 with NetworkManager in debug level.

I have reproduced this issue running Ubuntu Desktop 12.10 amd64 in Virtualbox: that will make testing easier if needed.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.7 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and leave the other tags. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

pdecat, thank you for testing the newest mainline kernel. Could you please plug your Netgear USB device in, unplug all other USB devices, execute the following in a terminal, and post the results here:
lsusb -v

FWIW, with the Ubuntu Desktop 12.04 64bit Live DVD (ubuntu-12.04-dvd-amd64.iso),
it connects only once but subsequent tries fail. I have to unplug then replug the adapter to make it work again.

pdecat, thank you for providing the requested information. Regarding your Bug Description:
>"Tried installing Realtek drivers (versions 3.4.2, 3.4.3 and 3.4.4) as suggested in #1030858, the 8192cu driver loads but it fails to activate the device (LED does not light)."

As the device identifies itself as a RTL8188CUS, have you tried the upstream Realtek driver version 3.4.4_4749 from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true#2742 ?

pdecat (pdecat) wrote :

Yes, I tried this one (it is the same download for RTL8188CUS and RTL8192CU).

Exact same behaviour with Ubuntu Desktop 11.10 64bit Live DVD (ubuntu-11.10-dvd-amd64.iso) :
* first connection works
* subsequent tries fail
* unplug/replug to repeat.

pdecat, thank you for providing the requested information. Could you please test for this in a Lucid live environment following http://releases.ubuntu.com/lucid/ ?

With Lucid (ubuntu-10.04.4-desktop-amd64.iso) and Maverick (ubuntu-10.10-desktop-amd64.iso), the adapter is not recognized.
Only message is "usb 1-1: new high speed USB device using ehci_hcd and address 2".

pdecat, thank you for testing Lucid and Maverick. Could you please test Natty via http://old-releases.ubuntu.com/releases/natty/ ?

Same with Natty (ubuntu-11.04-desktop-amd64.iso), device not recognized.

pdecat, the issue you are reporting is an upstream one. Could you please report this problem through the appropriate channel by following the instructions _verbatim_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream ?

Thank you for your understanding.

Marking Triaged as newest mainline tested, and regression testing completed back to Lucid.

You can forget about the PC hardware, because I am using a different PC (a Toshiba laptop) running Ubuntu 14.10 and this NetGear USB WNA1000M (0846:9041 [Realtek RTL8188CUS]) does not connect to Wi-Fi networks either.

Any other idea ?
