[vasyl4]

Please, help on Toshiba Satellite c855d I have wired internet, and i had wirelesses with d-link router. Now with Thomson TCW710 you can see wirelesses network but when you click on it after inserting password it seems to be connecting but after a while is asking for password again and eventually no connection ( wirrelles is working perfectly on ipod tauch).

Code:
$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:8c:fa:27:e8:ff

Right now I'm visiting parents for a week and time is limited, so please-please help.

So what kind of wireless device is it?

lspci -nn | grep 0280

Is the behavior improved if you detach the ethernet first?

Hi chili555,
Thank you for replying!
If I unplug wired there is no changes.

$ lspci -nn | grep 0280

I suggest you hook the ethernet back up and install the Ubuntu-ized version of compat-wireless. It seems to solve a lot of problems in these Real-hecks.

sudo apt-get install linux-backports-modules-cw-3.6-precise-generic

After it's installed, detach the ethernet, reboot and let us hear your report.

Did that. Unfortunately it is the same: taking password - connecting - and asking for password again.
Thank you

I assume this is using the driver rtl8192ce; verify:

lsmod | grep rtl

If so, let's try a driver parameter:

sudo modprobe -r rtl8192ce
sudo modprobe rtl8192ce swenc=1

If it works, write one file. CAUTION: don't blindly write the file unless it dramatically and perfectly works!

gksudo /etc/modprobe.d/rtl8192ce.conf

Add one line:

options rtl8192ce swenc=1

Proofread, save and close gedit.

EDIT: Off for the evening; see you tomorrow.

[sudo] password for maria:
maria@maria-Satellite-C855D:~$ sudo modprobe rtl8192ce swenc=1
maria@maria-Satellite-C855D:~$

No changes. So I didn't go further.

Since the behavior changed with a new router, let's see what changed there. May we see:

nm-tool

Is the cable-modem set to WPA2 only or the dreaded WPA and WPA2 mixed mode?

Dear chili555!

Somehow router was reset to defolt setting and i have wireless connection.
I think security setting screwed that.

So I thank you very-very mach for time, energy.

And I apologize for taking your time. I really appreciate your effort.

THANK YOU!

I was happy to help. I am glad it's working by whatever means.
