r8192se_pci driver occasionally drops connection, refuses to work with some networks

[Alex Wauck]

With any network, the connection will occasionally drop out. With some networks (I don't know what the determining factor is), the driver will connect, but I will be unable to use the network (connection attempts will time out).

Hi Alex,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. 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. Please let us know your results.

Thanks in advance.

This is affecting me too. Same laptop (ASUS 1201N). I've used ubuntu 10.10 64 and 32 bit versions and it's the same behavior. Looks like some other people with the same laptop are having problems too:

http://www.uluga.ubuntuforums.org/showthread.php?p=10387892

[leps (patrick-lepore)]

Also, somehow my bios settings get wiped out whenever the wireless flakes out

[leps (patrick-lepore)]

Other people are seeing the same issue. I found this thread:

http://ohioloco.ubuntuforums.org/showthread.php?t=1267961&page=11

[Marco Patzer (mpfusion)]

Affects me, too. Ubuntu 10.10 x86_64

[Feathertail (feathertail-deactivatedaccount)]

I am having this problem also, on a Compaq Presario CQ62-219WM. The problem has gotten worse after I upgraded to the Natty alpha. This thread on the forums describes my situation: http://ubuntuforums.org/showthread.php?p=10555397

Someone there suggests tweaking the power saving settings. I am not sure what the consequences of that would be though.

[Oliver Richards (richaoj)]

Problem still exists in 11.04 beta 2. Updating the to the 12/07/10 driver from realtek does not solve problem, though it makes it somewhat better.

[deibhaid (deibhaid)]

I have this issue as well. Ubuntu 10.10 x86_64

r8192se_pci modules

RTL8191SEvB Wireless LAN Controller (rev 10)

As a workaround, I had to write a script that removes the module, modprobes it, kills Network Manager and brings the network interface:

#!/bin/sh
# fix_wireless.sh

int=`ifconfig | grep wlan | awk '{print $1}'`

modprobe -r r8192se_pci
modprobe r8192se_pci hwwep=0
kill -9 `pidof NetworkManager`
ifconfig $int up
iwconfig $int key 10293847565647382910123456 essid "Grendel Cluster"
timeout 10 dhclient $int
if timeout 5 ping -c 1 google.com
 then echo "\033[33;3;148mConnected\033[39m"
 else sh fix_wireless.sh
fi

[Arif Ali (arif-ali)]

I am having the same problem, using the latest drivers from realtek rtl8192se_linux_2.6.0019.1207.2010

My machine is a Thinkpad Edge 15

I will try the latest mainline kernel from ppa, and see if I see the same problems

[Arif Ali (arif-ali)]

OK, tried the mainline kernel, and no luck at all

Tried the following
* 2.6.38.7-natty
* 2.6.39-rc4-natty

neither of these have the r8192se_pci

I tried the other drivers such as the rtlwifi and others that were there, but I got no wifi at all

[Arif Ali (arif-ali)]

The kernel below for me works

http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2011-06-02-oneiric/

i.e. 3.0.0-999-generic

The driver being used here is rtl8192se, and the stability issues I had are now gone, will test for a few more days and see how it goes

[Jose Marquez (ubuntu-hackwater)]

The 3.0 release candidate 4 kernel worked for me (from Mainline Kernel Builds), as above. 9 hours so far, stable connection on Kubuntu 11.04, connecting to a WPA2-PSK AP. I've got the Realtek 8191SE chipset in a Toshiba Satellite A500. So this seems fixed for Oneiric. Going to try drivers Realtek just sent me (newer than the December 2010 drivers on their site) with the stock 11.04 2.6.38 kernel.

[Arif Ali (arif-ali)]

Yeah, I have used rc2 to rc4, and all have given me stable connection using the rtl8192se driver, I am using the natty build with the oneiric kernel

[Jose Marquez (ubuntu-hackwater)]

I received drivers from Realtek today that seem to fix this problem for me. Stable connection so far without having to resort to the 3.0 kernel. I posted the drivers here: http://ubuntuforums.org/showpost.php?p=10989459&postcount=135

Go to page 14 of that thread for context, but it seems that the only issue with those drivers is some kind of conflict with conky. Also, the makefile creates three driver modules; I edited it to only have it build the rtl8192se driver module (note the name change), and I disabled the r8192se_pci module before running any of the make commands.

[Jesse Glick (jesse-glick)]

See bug #783010 which has a possible workaround.

[penalvch (penalvch)]

Alex Wauck, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. 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. Please let us know your results.

Thanks in advance.

[Alex Wauck (awauck)]

This bug no longer seems to affect my machine (at least as of 11.10). I don't know if the other people who commented here have had their problems resolved, but they don't appear to have said anything about it since August. I'd say it's safe to close this bug.

[penalvch (penalvch)]

Alex Wauck, this bug report is being closed due to your last comment regarding this being fixed with an update. For future reference you can manage the status of your own bugs by clicking on the current status in the yellow line and then choosing a new status in the revealed drop down box. You can learn more about bug statuses at https://wiki.ubuntu.com/Bugs/Status. Thank you again for taking the time to report this bug and helping to make Ubuntu better.
