I have been using my LM 17 for over 5 months but after an update now my wifi can't connect at all. Here is some info.

I need help, please. I am to the point to reinstall my sys but I want to learn.

Try

Code: Select all

sudo ifconfig wlan0 up

If it gives an error about rfkill state then

Code: Select all

rfkill unblock all && sudo ifconfig wlan0 up

Hello, Jeremy.

I tried the code but it did not give any inputs, this is what I got:

Code: Select all

davilalb@fdavilalb-Satellite-L775:~ >     sudo ifconfig wlan0 up
fdavilalb@fdavilalb-Satellite-L775:~ >

And just so you know, I tried the next code and gave the following input:

Code: Select all

fdavilalb@fdavilalb-Satellite-L775:~ >     rfkill unblock all && sudo ifconfig wlan0 up
Can't open RFKILL control device: Permission denied
fdavilalb@fdavilalb-Satellite-L775:~ >

My wifi all it does is trying to connect, but just keep prompting "connection deactivated" so what will be the next step? I do appreciate your time you are granting me here.

Anything else that I can do to get my wifi back?

lead67 · Post by **lead67** » Sat Aug 22, 2015 9:58 pm

I have a question. I have been searching for a fix on my issue, and found this so my question, is this something I can apply to my problem?

Thanks

There's a "sudo" missing in the last command that you tried.... It should be:

Code: Select all

sudo rfkill unblock all && sudo ifconfig wlan0 up

I had entered the command as specified, but still did not work.

Code: Select all

davilalb@fdavilalb-Satellite-L775:~ >     sudo rfkill unblock all && sudo ifconfig wlan0 up
fdavilalb@fdavilalb-Satellite-L775:~ >

I want you guys to know that I am doing my homework, too. I want to learn and remedy this issue, and as you can see my is not associated and can't get the IP.

Code: Select all

fdavilalb@fdavilalb-Satellite-L775:~ > iwconfig wlan0

          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

so what would be the next step to get my wifi back? as I said, it was working perfectly but after the update it is not.

With an ethernet connection open terminal and run

Code: Select all

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

And post the contents of the wireless-info.txt file created

I would change the channel of your wifi router to a channel other than 11 and if it is using a password, change encryption settings to WPA2-AES, WPA2-PSK, or WPA2 only

You guys are the pro, but do you think it will make a difference? since it was working fine until I had the update, but I will try and reply on the matter. Thanks.

Success! WOW! I love mi Linux Mint family, I always get my issues resolved. How do you know that I needed to change my security configurations and why after the update did it stop working?
I want to learn more and I would like for you guys to guide on the right path, so what books do you recommend will be good for a newbie?

Please let me know if I picked the right channel:

Linux has had issues with TKIP and WEP encryption for a while, it may be because the developers don't want to support the less effective encryption method

There were a lot of other wifi access points on the same channel as yours and that can cause issues even with yours being the strongest

Have fun and enjoy your wifi

But what book or books should I search so that I can educate myself on this? Your reply will be appreciated.
