wifi lost after update - silverjock - 10-25-2019

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

  Is  this  what  you  need?            https://github.com/brektrou/rtl8821CU

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

Code:
sudo ./dkms-install.sh

follow whatever it says. You may or may not need to reboot after to get wifi.

    Further  problem  with  laptop now,  won't  boot,  stops at BusyBox  which is gobildygook  to  me,  so  may  be  a  while  till  I  can  try  your  fix.
  Thanks  anyway

Managed to get boot up
tried  above  command in terminal  but  get
command not found
thanks

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.

sorry for  my  lack of ability.  I  thought  i  was  in  folder,  When  I  click  on  folder  the  first  opens  as  driver (another  folder)  click  again  opens  with    a blanked  out  folder  symbol  and  rtl8821cu  wifi linux  etc  listed  acroos  the  top  further  click  and  a blank  page  appears.    If  I  right  click  on  the  page  with  rtl8821cu  etc  I  have  options  to open-  open in new  page-new widow-open  terminal-  or open  as  administrator  are  any  of  these  the  right  one?  or  is  the  file  required  somewhere  else  and  if  so  how  do  i  find  it  Thanks
