Wireless networking works fine for about 60 seconds then it freezes or something, can't resolve any domain names, and the only way to get it going again is to reconnect... any ideas?

I have a similar problem using this solution - my internet freezes after a while (usually few minutes) or it'll freeze if I start downloading something. Tried tweaking MTUs but that didn't seem to have any effect. Ideas ?

IT WORKED FOR ME TOO!!!!

THIS WAS THE BEFORE......

I have a Toshiba Satallite A665D-S5175 I cannot get my Ubuntu 10.04 to detect the wireless.

Thanks to canucked. That worked perfectly on L655-S5150

For beginners, this is what I ran in Terminal to get the Realtek RTL8188CE wireless working on a Toshiba L655:

Code:

sudo add-apt-repository ppa:lexical/hwe-wireless
sudo apt-get update
sudo apt-get install rtl8192ce-dkms

...but nice work with that script, satellite-of-love!

This also worked on my Toshiba Satellite L645D-S4056 !!!
Thank you so much!

@Colonel_Ingus, gibffe:

According to someone else's post, you may have difficulty maintaining a connection because of the type of wireless encryption in use.

From this post:
http://ubuntuforums.org/showpost.php...8&postcount=15

tdrusk says: "The driver does not seem to connect to WEP 40/128-bit Key with Open Authentication connections well. If you are having problems with the internet not working after a few minutes you may need to change it to a WEP 40/128-bit Key with Shared Authentication."

Because WEP encryption can easily be compromised, I would suggest switching to WPA or WPA2 wireless encryption if possible.

@tlcstat:

After a kernel update in February (I think), the Realtek RTL8188CE wireless on the Toshiba L655 stopped working. I too had to disable, reboot, then re-enable the restricted driver in Additional Drivers. Wireless then worked fine.

After the most recent kernel update, I noticed that this kernel module, rtl8192ce-dkms, failed to properly compile according to the Terminal output, yet wireless still worked. I wonder if support for the RTL8188CE was added to the newer linux kernel.

Also, Ubuntu 10.10 would not allow removal of rtl8192ce-dkms in Synaptic.

I have no interest in reinstalling Ubuntu 10.10 just to find out if wireless works without rtl8192ce-dkms. But I intend to try the 11.04 Natty beta Live USB to see if wireless works without adding the lexical/hwe-wireless PPA or manually compiling the driver.

Hi all.
I too have been struggling to get my toshi c660d to detect its wirelss card. my os is natty. i've tried canuck's suggestion, but to not apparent avail.
After the line:
sudo apt-get install rtl8192ce-dkms

i get:
Reading package lists... Done
Building dependency tree
Reading state information... Done
rtl8192ce-dkms is already the newest version.
The following packages were automatically installed and are no longer required:
kdelibs4c2a libqt3-mt-mysql kdelibs-data liblualib50 libavahi-qt3-1 barcode
apport-hooks-medibuntu liblua50
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 29 not upgraded

there's not change with the non-detection of card and as a newbie to ubuntu, i dont know what to do at this point.

Can anyone clarify the problem?
thanks in advance

Toshiba NB-500 here.
The wireless drivers are working in Ubuntu 11.04, no need to install them manually anymore.

Although, the internet connection gets freeze for a few seconds intermittently. And I'me using WPA2 wireless encryption.

Any thoughts on this? I believe that this wifi drivers issue is causing a little overheating and excessive power consumption too.
