ASIX AX881 79 USB 3.0 to Gigabit Ethernet Adapter not working

[HarrysGulf]

when CAT5 cable is plugged into laptop port, status shows "network cable unplugged".  when trobleshooting protocol is used, the same result -- network cable unplugged.

then switchig to an external USB drive (startech.com) etherent adapter, the wired LAN connection is completed and the laptop is able to access the internet.

since the same identical CAT5 cable is used in both cases, and the laptop recognizes the CAT5 in one case and not in the other -- it appears to suggest that the internal network ethernet adapter has some sort of problem / issue (driver?)

it should also be noted that selecting the network adapter in the "device manager" does not show any issues / problems.  Everything looks normal and the status of the device shows "working properly".

I would prefer to use the laptop internal adapter when connecting to the internet from a wired connection (CAT5) rather than the external USB ethernet adapter.

Hi

There are 12 Network Drivers for your Laptop here...

https://support.hp.com/gb-en/drivers/selfservice/hp-probook-4545s-notebook-pc/5229461

You may already have the correct drivers installed.

I hope you can run a Command Line Interface / Command Prompt / DosBox as an Admin.

Initially try WinKey + R and type cmd.exe

Then try getmac and ipconfig -all in the screen, similar to this...

Ethernet adapter Ethernet:

   Media State . . . . . . . . . . . : Media disconnected
   Connection-specific DNS Suffix  . :
   Description . . . . . . . . . . . : Realtek PCIe FE Family Controller
   Physical Address. . . . . . . . . : BB-BB-BB-BB-BB-28
   DHCP Enabled. . . . . . . . . . . : Yes
   Autoconfiguration Enabled . . . . : Yes

And the above is probably indicative of your own results. 

Where we need to get is (Cable now connected)...

Using Device Manager and if necessary entering manual values.

So please try the above and copy and paste any relevant results.

here is the command prompt details you requested (hopefully they are attached below).  the setup of the laptop when I ran this command prompt was: 1) wireless network connection was intentionally disconnected; 2) external USB drive ethernet modem was connected; 3) no CAT5 wire was connected to laptop connection on side of laptop.

p.s. this is my first time using this process.  I don't see a way to attach a file.  The only way I could find to save the details from the command prompt screen was to paste it into WORD.  Then I had to covert it to PDF, then to JPEG so I could attach a photo to this reply note.  If there is a better way to save the info from the command prompt screen, please let me know.  Also, if there is a way to attach a file (WORD or PDF) to this mesage system, please let me know.

Hi

I press PrtSCn  printscreen and paste into paint, tidy up and save as a jpg.

OR the edit has copy and paste directly from the 'box'.

Hi

I see too many devices included.  VPN etc.

With everything connected..

So ping to a 127.0.0.1 usually works and shows the adapter is installed.

Then ping 8.8.8.8 and 13.107.4.54 are external places.

Removing/Disabling a device until only the Internal Ethernet is left.
