Thank you for taking the time to report this bug and helping to make
Ubuntu better.

You mention installing the most recent kernel for Ubuntu 18.04 LTS,
which currently is the 5.0 series (ie. a new install using Ubuntu
18.04.2 or 18.04.3 achieves this, or enabling HWE or the hardware-
enablement stack on older install media) but I see evidence of the use
4.15 series kernel, not 4.18/5.0 (not the latest, but available for
18.04 without specialized install steps).  The use (or evidence of) the
later kernels may also help make this bug-report more useful (it looks
more like it was filed on a 'live' system).

You may find help with your problem in the support forum of your local
Ubuntu community http://loco.ubuntu.com/ or asking at
https://askubuntu.com or https://ubuntuforums.org, or for more support
options please look at https://discourse.ubuntu.com/t/community-
support/709

You can also change this bug-report into a question, to try and get you
help, but even support sites may benefit from details of what
instructions you followed (to verify they applied to your situation),
who "they" are that told you to do steps, plus details of what those
steps were.

Currently the description and detail here do not match, so it may be
possible that little can be done.

Title:
  no wireless adapter was found ubuntu 18.04

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  recently I just installed ubuntu 18.04 lts in dual bot next to windows
  10. Everything in the installation was fine until the moment to start
  session. The problem is that the wireless network card does not detect
  me and when entering the configuration I simply get an error message
  saying that no wireless adapter was found. I have already followed all
  the tutorials I found on the web. and update the driver of a github
  repository, and install how much program they told me to install and I
  still can not connect via wifi.

  I just do not know what to do. I have a laptop hp 14-bs004 came with
  windows 10 installed. The information on the network card is as
  follows:

   Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec: 
d723]
  Subsystem: Hewlett-Packard Company Device [103c: 8319]
  Control: I / O + Mem + BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- 
Stepping- SERR- FastB2B- DisINTx-
  Status: Cap + 66MHz- UDF- FastB2B- ParErr- DEVSEL = fast> TAbort- <TAbort- 
<MAbort-> SERR- <PERR- INTx-
  Interrupt: pin A routed to IRQ 255
  Region 0: I / O ports at 1000 [size = 256]
  Region 2: Memory at 91000000 (64-bit, non-prefetchable) [size = 64K]
  Capabilities: <access denied>
  Kernel modules: wl

  already install the most recent kernel, already intale driver driver
  realtek rtl8723be according to the instructions of the git repository.
  and nothing has worked.
