wireless card problem rtl8192se autodisconnects after a few minutes in 13.04

Asked by pspencil

I am using wireless card rtl8192se. The official site of realtek provided a driver that supports kernel up to 3.2.x but recently i upgraded to 13.04 so i cannot use it.

Initially the driver in the kernel works find but after a while it start disconnecting after a few minutes.

The signal strength shown in the panel drops from 4/5 to 2 yet if I click open the menu, the strength remains. In the same time, network slows down drastically (from 100+kb/s to 100b/s). Only if i disconnect and reconnect will it start to work. but after a few minutes, it appears again.

This is not a new problem, but I cannot find a solution to that, especially with kernel 3.8.x.

Previously I switched from 12.10 to 12.04LTS also because of this problem.

Hi,

Please first connect your wired network adapter to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1:

If you are using the Gnome interface, open the Terminal console via "Applications->Accessories->Terminal"

If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.

The methods in Unity are:
Press Control-ALT-T key combination.
Dash > Search for Terminal
Dash > More Apps > 'See More Results' > Terminal
Dash > More Apps > Accessories > Terminal

Step 2: Please copy-paste the following command from https://help.ubuntu.com/community/WirelessTroubleshootingProcedure in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word lsmod. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo apt-get update; sudo apt-get install hwinfo grep rfkill; sudo lshw -C network; rfkill list; sudo iwlist scan | egrep -i 'chan|ssid'; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep '02:00|80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rror|rtl|rt2|rt3|rt5|rt6|rt7|usb|witch|wl';sudo dmidecode|egrep 'anufact|roduct|erial|elease'; iwconfig; cat /etc/modprobe.d/* | egrep '80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|wmi|witch|wl'; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|egrep 'wpa|icd|etwork'; netstat -rn ; cat /etc/resolv.conf; sudo lsmod

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Regards,

Mark

The required information is as follows. Some are not shown as I cannot scroll up anymore, but they are basically software sources from the "apt-get update" so I do not think that matters a lot.

Also, I am using a Thinkpad E40 0578B32. The wireless card I believe is rtl8192se (rtl8191sevb?).
Thank you.

Please try this solution: (appending "acpi=off" to the kernel entry in /boot/grub/menu.lst)

https://bbs.archlinux.org/viewtopic.php?id=114745

Your Terminal output also shows another issue:

                    Channel:8
                    Frequency:2.447 GHz (Channel 8)
                    ESSID:"WiFi@Dunman Hostel"
                    Channel:3
                    Frequency:2.422 GHz (Channel 3)
                    ESSID:"WiFi@Dunman Hostel"
                    Channel:4
                    Frequency:2.427 GHz (Channel 4)
                    ESSID:"WiFi@Dunman Hostel"

There are 3 SSID's (wireless router access points) with exactly the same name (WiFi@Dunman Hostel). Furthermore, the SSID name contains a special character and a space. I suggest giving each SSID a unique name, in small letters, without any @ or space in the name. That may also help.

Then reboot each wireless router.

pspencil (pspencil123456) said : 		#6

There is no menu.lst file under that folder. Should I create one?

Also, as u can see, it is a hostel wifi, whose router I have no access to. Is there any other things I can do to modify the SSID?

Thank you.

Revision history for this message
Mark Rijckenberg (markrijckenberg) said : 		#7

Please run this command:

gksudo gedit /etc/default/grub

Using the gedit editor, please replace the following line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

with the following line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

Then run

sudo update-grub

Then reboot and retest.

If you do not own the wireless routers and cannot modify the SSID yourself, and the acpi=off boot configuration idea does not work, then I unfortunately have no further suggestions to make.

pspencil (pspencil123456) said : 		#8

So the problem is due to the repeated SSIDS or the inappropriate naming of the SSID? Because in school, our school wifi also has a space and an "@" inside the SSID, but the same problem does not seem to appear under school wifi.

Revision history for this message
Mark Rijckenberg (markrijckenberg) said : 		#9

I only know that it can help to change the SSID name and remove spaces in the SSID name in other cases that I encountered. The suggestions may work or may not work. It is only a suggestion... You can still try the acpi=off suggestion....

Here are a few examples where I suggested changing the SSID name:

also try:

echo "nameserver 8.8.8.8" | sudo tee -a /etc/resolvconf/resolv.conf.d/head

Reboot to test

It does not work. The problem appeared again. I try run the above command again when the problem appears and here's what I get. Interestingly, it seems that either the wireless self-recovered or during my running the command, the wireless recovered on its own.

Hope it could help.

A new seemingly trivial discovery. The wireless is working for the whole afternoon. But after I left it idle for about 1 hour, it start dropping and reconnecting and dropping again and again with a time interval of about 10minutes.

Once again, I do not know whether this could help. I do not even know whether there is a direct correlation between idling and poor connection.

Idling should theoretically mean A better connection as the CPU is freed for use with wireless... If you still have this issue, I'll try to find a solution.

See also bug Bug #1175554 on a Thinkpad W701.

On a Lenovo ThinkPad Edge 15" 0302 I have the same problem as above.

Install kernel 3.9.4. It solves all rtl driver problems.
See https://wiki.ubuntu.com/Kernel/MainlineBuilds for instructions.

Thank you. I really appreciate your generous help. But, forgive my ignorance, which kernel are u referring to? The webpage is full of folders. And the kernels are numbered in a way like this 3.x.x.xxx like the 3.9.0.994. I do not think u are referring to this right?

Wait, are u referring to the 3.9.4-saucy? That sounds right.

I am also facing the similar issues in my device you can see here https://rangefindereviews.com/ the details in my project that is in process and slow just because of this issue.

Can you help with this problem?
