[SOLVED] No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?
Hi.
My Wifi stopped working but it had previously been working just fine. I've been using Linux Mint for over a week with no Wifi issues so I don't understand why this would happen now.
I had to use a USB Wifi dongle in order to post this. The USB Wifi dongle works as it should, but why doesn't my computer's built-in Wifi work anymore?
The distro of Linux Mint that I'm using is Linux 18.3 Sylvia and the desktop environment is Cinnamon 3.6.6 if that helps.
Thank you.

Hello mintyfreshuser and welcome to the Linux Mint Forums,
First lets get a look at your system and see if we can diagnose the problems would you go to a terminal and type the following commands and post the outputs here:

Re: No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?
you can try this command and reboot see if it works.
Rtl8188ee has caused problems for quite awhile.
I suspect that the last update you did included and kernel update and that is what might have caused the problem.
good luck.

Not sure why wifi is hard blocked?! I was using it normally in the morning and afternoon without any update wifi didn't want to start up. I was trying to turn it on and off in BIOS but nothing has helped.
When i left click on network icon and try to turn it on switch button do not want to move it is just ''slipping''. When i go to network settings wifi switch goes on but then after some time it goes back off. :/
Not sure what is a problem.
Please help me somehow. Thanks a million.

Re: [SOLVED] No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?
I would try
Reboot
Code: Select all
sudo apt-get remove bcmwl-kernel-source && sudo apt-get install firmware-b43-installer
Re: [SOLVED] No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?
Hard block means that some how you hit or the machine decided to switch off you wifi card.
You'll have to find what the combo of keys or a physical switch on the machine will turn it back on.
on my machine the switch is the FN+F1 key. But it's different on each manufacturer's machine.
find the owner's manual. If you don't have one try searching on line. Good Luck.

Re: [SOLVED] No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?
Thanks for a super fast replies.
I have removed and reinstalled drivers as JeremyB instructed but nothing has changed. Actually, now when i apply command rfkill list
i have only this:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
I do not have phy4 option as before.
It is true, i have dedicated hard button on laptop for wifi on/off but also when i press it nothing changes :/ For as much i could tell i do not have keyboard combo for it.

Re: [SOLVED] No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?
HI,
According to the manual from dell there is a switch on the left side of the laptop near the HDMI output that switch must be turned on. did you accidentally turn that one off?
You can download a copy of the manual from here: https://www.manualslib.com/manual/11437 ... e=9#manual
Look at Section 2:7 & 2:8.
Good luck.

Re: [SOLVED] No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?
Thanks for a reply. I am aware of that button but for some reason when i press it nothing happens, i mean, output in terminal is the same and still there is no option to turn the wifi on. :/
Re: [SOLVED] No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?
I have the same card as you and it is the bcmwl - driver that works best with it. so if you did as JeremyB said and installed the b43 driver please make sure the switch is in the on position and plug into a Ethernet connection and reinstall the bcmwl-kernel-source driver. Then try again.
By the way it's always better to open a new thread for your own problem than reopen one that was solved. Just for future knowledge.
P.S. you may have to reboot the machine for it to work after you've installed the driver and made sure the switch is turned on.

Re: [SOLVED] No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?
I've also noticed that my WiFi with a Broadcom Wireless Adapter was not working in a freshly installed Linux Mint 19.1, despite that the driver bcmwl-kernel-source was installed.
Apparently the problem was related to this wizardry with Secure Boot, MOK, and driver signing. I could fix it with
I was asked to choose a password and on the next reboot i was prompted to use it to enroll some MOK or something like that. After this operation the WiFi got fixed.
