I have an issue and can't connect to any wifi in Ukraine. I'm using a gigabyte 2442 laptop and running Ubuntu 14.04 on it only. Every time I turn on the laptop I have to go to land settings to turn off the Hotspot and after I turn it off sometimes it takes 2 times to get the list of available wifi spots. And I click on my wifi, for some reason it just doesn't want to connect. I press the connect button and it just ignores me. There is no action what so ever. I'm stuck and I don't know what to do. Is that a chip problem. The laptop is made in thaiwan and my one was bought in Canada. I don't know if that's a usefully information or not but I can't understand what the matter. Anyways if anybody knows what's the problem or had the same issue please let me know how I can solve it. The model of the router is tp-link 150mbps wireless n adsl2+ modem router And I'm a fairly new user ID the Ubuntu OS

I've tried a method that I've looked up on this web site and it didn't work. Know Lan is not showing any network at all since I've put all those codes in my terminal is it possible that I've blacklisted some settings on my wifi?

Below is the list of codes that I've typed in to my terminal. 

sudo apt-get purge bcmwl-kernel-source

reboot and you may need to blacklist b43 and/or ssb but you can try this after a reboot one line at a time and see if you are able to connect

sudo modprobe -r b43
sudo modprobe -r ssb

If you are able to connect only with using the modprobe -r b43 then echo "blacklist b43" | sudo tee /etc/modprobe.d/b43.conf If it also took the modprobe -r ssb to connect then do both echo "blacklist b43" | sudo tee /etc/modprobe.d/b43.conf and echo "blacklist ssb" | sudo tee -a /etc/modprobe.d/b43.conf and wifi should connect

  • The router's model is seldom relevant. Troubleshooting starts with the WiFi device. Please [edit] your question and add output of lspci -knn | grep Net -A3 terminal command. –  Aug 17 '17 at 12:12
  • OK the first command gave me a lot of information what do I have to look at to troubleshoot? At the end it says kernel driver in use iwlwifi. And kernel modules iwlwifi – eugene Aug 17 '17 at 15:36
  • And what should I edit in my question? I'm fairly a noob with this – eugene Aug 17 '17 at 15:40

  • Please [edit] your question and add output of lspci -knn | grep Net -A3 terminal command. It is one command, not two. – Pilot6 Aug 17 '17 at 16:49

    Better yet, follow the instructions in this answer and edit that information into your question. Thanks! – Seth Aug 17 '17 at 17:20
