10ec:8192 WiFi Realtek 8192E disconnects after a while and fails to reconnect

[Gilbert Dion]

A few minutes after booting my Samsung R580 laptop, the Wi-Fi disconnects and it fails to reconnect until I restart the machine. This happens with all the 64 bit versions of Ubuntu I tried, from 14.04 to 15.10. With the 32 bit versions, everything runs perfectly. No loss of connection at all, even after 48 hours in a row.

Here is the output of iwconfig after loss of connexion:

eth7 no wireless extensions.

lo no wireless extensions.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.4 kernel[0].

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'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[0] http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-rc5-wily

[Gilbert Dion (diong)]

Sorry, I don't know how to add a tag. This tag would be "kernel-bug-exists-upstream". And the bug is already marked as "Confirmed".

[penalvch (penalvch)]

Gilbert Dion, could you please provide the full computer model as noted on the sticker of the computer itself (not from the Bug Description)?

[Gilbert Dion (diong)]

Samsung Notebook
Model NP-R580
Model Code NP-R580-JS03CA

Note: I have seen this wireless card issue in various forums on different
machines back from 2011.

Since the Samsung bios updater is Windows only, I had to create a partition and install Windows on it to perform the update.

The update did not change anything.

Here is the output of dmidecode -s bios-version and dmidecode -s bios-release-date

Gilbert Dion, 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 mailing list? As per modinfo rtl8192se, TO Larry Finger, Realtek WlanFAE, and lizhaoming, CC linux-wireless.

Please provide a direct URL to your post to the mailing list when it becomes available so that it may be tracked.

Thank you for your understanding.

[Gilbert Dion (diong)]

Can you help me please: I can't figure out which mailing list you are talking about. Where can I find this address, or the addresses of Larry FInger and the others.

[Gilbert Dion (diong)]

ok, I found this:

RTL8192CE WIRELESS DRIVER
M: Larry Finger <email address hidden>
M: Chaoming Li <email address hidden>
L: <email address hidden>
W: http://wireless.kernel.org/
T: git git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-testing.git
S: Maintained
F: drivers/net/wireless/rtlwifi/
F: drivers/net/wireless/rtlwifi/rtl8192ce/

but there is no "Realtek WlanFAE".

I'll send my report Tuesday or <wednesday.
