Complete novice and silver hair  so spoon feeding  only!  My  wife's  laptop  has  been  working  ok on  usb  wifi  till I  updated  today.  I  had  to  have  a  friend  install drivers  for  this usb  device  but  no  idea  how  he  did this.  After  update  no  wireless options  appear  to  click  on  (  I  assumed  this  would  be  automatic )  I  can  use  terminal  if  spoon  fed,  2  propriety  drivers  show  when  I  check  network  connections  from  menu.  how  do  I  get  back  on  line
 thanks

Can your friend not load the drivers for you again?

Thanks  for  reply   unfortunately  friend  was  just  visiting,  does  the  driver  have  to  be  loaded  again  and  if  so  how  is  this  done?
The  driver  folder  is  on  the  desktop  /  the  usb  shows  on  ls usb/  the  chip  is  rtl 8811cu / dkms is  installed.
 Would
  sudo ./dkms -install.sh
sudo modprobe  8811cu
iw config
 be  the  way  to  go?    Found  this  between  github  and  forum  search  but  unsure  if  this is  what  I  need
  Thanks

Make sure you are inside the driver folder, then open a Terminal and do:

Code: [Select]
sudo ./dkms-install.sh
follow whatever it says. You may or may not need to reboot after to get wifi.

Command not found means that you are not in the folder where the install file is. Have another look at my previous instructions and try again.

Right click inside the folder that has the dkms-install.sh file and follow previous instructions.

My thoughts  too
   but  decided  too  give  local  repair  shop  a  try  as  friend  would just  be  at  internet  distance  too!
  Will  post  what  was  wrong  here  after  visit  if  i  can,  in  case  it  is  helpful  to  someone  else
  Thanks  for  your  patience  .

@Jerry  Been following this. Interesting to me that firmware-realtek is still in Debian backports while I could not find the package in multiverse. Is it named something else now or is realtek support only on git?
