WIFI networks no longer appearing

[brajawill]

I installed LM 17 and everything was fine with my wifi networks until now. Now, no wifi networks even appear, and I have to manually type them in under network connections.

The only change I can think of that may affect this is that I was just in Bulgaria (where it worked fine), and now I'm in Turkey (where this change happened).

Any ideas? Help, I'm a newbie. Thank you!

In terminal

Code: Select all

iw reg get

Code: Select all

cat /etc/default/crda | grep REGDOMAIN

[brajawill]

below is whate happened. any ideas?

mate@mate ~ $ iw reg get

Ok we will try to set it up for Turkey, which has country code TR

Code: Select all

sudo iw reg set TR

Code: Select all

 sudo sed -i 's/^REG.*=$/&TR/' /etc/default/crda

and reboot

Run this script on the computer with ethernet connected, it will make a report named wireless-info that contains info that is helpful in diagnosing issues

Code: Select all

 wget -N -t 5 -T 10 https://dl.dropbox.com/s/qjc87hzk1z5x6z0/wireless_script && chmod +x wireless_script && ./wireless_script

I just did this and then rebooted and now my internet doesn't work at all!

[brajawill]

I realize now that you said to run that with Ethernet connected, but I did not see it before and ran the script without pluggin one in. now I have no internet. also, I do not have an Ethernet cable.

how can I fix this to at least get internet back?

ay, ay, ay...sorry

Ethernet/wireless, you just need an internet connection to download the script. Can you copy the wireless-info file from home to a USB or any method to post it here

See if

Code: Select all

rfkill list

shows anything blocked

And

Code: Select all

lspci | grep -i network

should tell us what network hardware is there

okay, now the internet is working again...i'm not sure why

though, still no wifi list--the original problem

[JeremyB]

Do you still have the media(USB/DVD) that you installed LM with? You might want to boot it up and see if the same behavior exists, if you don't have many modifications or programs installed it might be worth trying a reinstall and not reformatting the partition you want to install to, as it should save some of the info in your /home folder

From the report the

I do not have installation media any longer. C'est la vie. As long as the internet works, then this is fine. Thank you very much for all your help!
