Toshiba Satellite C855 wireless not working on a clean install, Ubuntu 12.04 LTS

[bruti]

Unfortunately, I am not getting the same results that the other posted was getting. The first time I followed the instructions in that post, "Enable Wireless" appeared. However, no networks were found. I rebooted my laptop and the router as he did, but now the "Enable Wireless" option is gone again. Redoing the steps did not yield any results (the enable wireless option doesnt even appear now)

Let's follow the same diagnostic process:

dmesg | grep rtl
lsmod | grep rtl
iwconfig

Thanks.

Sure thing.

dmesg | grep rtl

 lsmod | grep rtl
rtl8192ce              53780  0 
rtl8192c_common        47696  1 rtl8192ce
rtlwifi                65273  1 rtl8192ce
mac80211              475488  3 rtl8192ce,rtl8192c_common,rtlwifi
cfg80211              181041  2 rtlwifi,mac80211

iwconfig
lo        no wireless extensions.

Let's retrace the firmware step:

ls -al /lib/firmware/rtlwifi

Then please reboot and let me see:

dmesg | grep rtl

Thanks.

I'm not exactly sure how that changed anything.. but I am currently posting from the laptop that couldn't previously connect to the internet. What is this magic?

I'm not sure. Perhaps it needed a little encouragement, also known as a reboot!

I'm glad it's working by whatever means. Have fun!

I just find it odd that it did not work after the first reboot, but it did after the second.
You've effectively troubleshooted and solved an issue for me in regards to my PC and Laptop wireless issues.

I'm beginning to think there is no wireless issue you can't solve

Edit: Marked as solved.
Thank you very much, it would have been terrible to keep going to school without wireless!

I wish it were so. There are a few I've lost over the yaers. Thanks for your nice comments.
