Hello guys, please after installing ubuntu 16.04 my wlan doesn't seems to work, iwconfig shows
wlo1 IEEE 802.11bgn ESSIDff/any
Mode:Managed Access Point: Not-Associated Tx-Power=off
Retry short limit:7 RTS thrff Fragment thrff
Power Managementff

eno1 no wireless extensions.

lo no wireless extensions.

My wireless refuse to work after its being enable.
pls help me out.

My guess is that your WiFi is blocked. I haven't used Ubuntu for awhile, so I don't know if rfkill is installed by default, but could you try this command in a terminal:
And post the result on this forum.

Best regards,
HMW

Hi Michael, welcome to the forum

I'll need some additional information concerning your wireless adapter. Please open a terminal and post the results (using the code tags) of these commands...

You can omit the last entry if your are using a desktop system, not a laptop.

Disclaimer: Be careful with commands including "sudo" especially, as it will essentially allow root access to your system. Mistakes could possibly damage or even destroy your OS.

Regards...

Ok, so your wireless is "hard blocked". That usually means there is a physical switch to turn WiFi on and off. Do you have such a switch on your computer?

It can also be disabled in BIOS. But first things first: please provide model and any other possible identification of your hardware.

Best regards,
HMW

Hello my Engr's, this re the result i got bout the wlan issue, i'll be grateful if the issues re solved for me.Big thanks to you guys.

Hi...

Please see HMW's response above. Your wireless adapter is disabled via the hardware. What is the brand and model (and model number) of your laptop?

Regards...

The Enable wi-fi switch is active for me to decide whether to enable or not but there is another switch which shows <wi-fi is disable> and <wi-fi network> they are in Grey white not the normal white and it shows that i don't have any access to click on those switches on less i perform a troubleshooting which i don't know how to and that was why i had no access to wireless network except using lan. I'm grateful for your help sir's. I love using LINUX and i know you guys are gonna help and i will also try my best(GOD BLESS YOU).

Hi...

May God bless you, as well.

I'm not sure what you mean by two switches, there is only one hardware switch. Could you explain this in more detail and provide the brand and model (and model number) of your computer?

The BOLD ones are active while the Grey ones aren't active on my laptop. I'm using HP_635 AMD processor 4gb RAM.

Thank you. There are several suggestions as to how to fix this problem in Ubuntu:
