I just changed my OS from windows to ubuntu 16.10 and the problem is since then my wireless doesn't work at all, I can't see any WİFİ conection so I have to plug the ethernet cable to get connection.I don't know where is the problem since it was working well in windows. But I checked the network hardware by this comand lshw -C network and here is the output

  • how can I check my drivers?? what is the comand?? – Kalbert Mar 17 '17 at 16:52
  • oh nvm, you did it... –  Mar 17 '17 at 16:54
  • hmm, it says here on the generic side, illegal vendor id, there's clearly a problem on the wireless interface. @kalbert –  Mar 17 '17 at 16:56
  • oh wait you dont have windows xD –  Mar 17 '17 at 17:03
  • how can I fix it please?? I really need it. – Kalbert Mar 17 '17 at 17:12
  • I would power it down and remove the wireless card and reinstall – Jeremy31 Mar 17 '17 at 17:34
  • could you explain clearly how to do that??@Jeremy31 – Kalbert Mar 17 '17 at 17:42
  • Do a google search for you laptop model and wireless card, you will likely find instructions or a video – Jeremy31 Mar 17 '17 at 23:17
  • i doubt that will work- give ^ a try, tsk tsk compatability. or just stick with plain wires –  Mar 18 '17 at 03:25
  • the rtl8723be driver it's for ethernet interface....as displayed in my code above it seems like the wireless interface doesn't show any driver since it says illegal vendor ID.....can someone help me with this? – Kalbert Mar 18 '17 at 09:09
  • Hopefully you've upgraded to a supported version by now and a newer kernel has resolved your issue. If you've moved to a supported version and still have this issue please review this and [edit] a link to a pastie of the output into your post. Thank you for helping us help you! – Elder Geek Sep 23 '17 at 18:37
  • Please upgrade to 17.04 and try. Newer versions ship with newer updates, the problem may be fixed. If it isn't, please give us your exact model number. HP Notebook 15 is a very broad model, there are many sub-models. – Seth Sep 24 '17 at 15:58

Did a net search - rtl8723be and ubuntu? Discovered that there are problems with setting up this Realtek wireless device. Some info was available about configuring this device that will be helpful to you. One caveat here - Follow instructions and enter commands Carefully! There seem to be some modprobe commands. This command works with kernel modules and are not to be used without healthy respect. You will have to connect to the net with either another PC or use the wired ethernet connection to get the information and any downloads that may be required. This search could be done on the Ask Ubuntu page as well.

  • Did not actually view a page, Links will be found by doing the same search - 'rtl8723be and ubuntu?' – Craig Mar 20 '17 at 22:32

Just go to additional driver ...put the LAN cable(internet cable) it will automatically search for the driver and just install it by selecting apply ...you will be able to use wireless internet in just few seconds... Go for it
