Linux Mint 19.1 HP laptop Realtek RTL8723DE no WLAN

Post by Cliff_G » Mon Jun 03, 2019 2:48 pm

I have a similar problem. New HP laptop with a Realtek RTL8723DE 802.11b/g/n PCIe Adaptor. I am trying Linux Mint via USB stick boot to begin with, so am not sure if I can install a driver for it as I assume it would need to be within the USB boot image.

Same with Ubuntu.

Any advice, anyone? Can I add the driver onto teh USB stick somewhere?

Thx in advance

Since this has been solved, you should probably start your own post.

Thanks, karlchen, wasn't sure if Solved meant threads were never looked at again.

As extra info I have found this HP thread: https://h30434.www3.hp.com/t5/Notebook- ... -p/6477307

So, basically, I can find a driver which if I have installed Linux Mint then I can swop in, so the question becomes:

How do I add in an extra driver to a boot-from-USB copy of Mint?. I'm not personally prepared to install it unless I get it working satisfactorily from USB stick, for exactly this sort of reason. I need it to "just work"

Hi, Cliff_G.

The "tag" [solved], prefixed or appended to a thread title, means that the user, who has reported a problem, has been given steps to solve his/her problem and that the user has confirmed that the solution worked for him/her.

The "tag" [solved] in a thread title is meant as a help for other users, who are searching steps to solve a problem which they experience, to find threads, where solutions have been given and where solutions have been successfully applied, too.

As a consequence, appending a second problem report to a thread, which has been marked as [solved] already, is less likely to be noticed by other users. As a rule, a thread should be about one problem only, not about several (different) problems.

In addition, if a solution , which has been confirmed by the thread starter, does not work for you, then your problem is very likely not identical to the problem, reported and solved in the thread. New / different problems deserve dedicated threads.

Regards,
Karl

Hello, Cliff_G.

About the problem that you cannot use your wifi interface in the Linux Mint live system yet. As a consequence of which you cannot use it during the installation, either.

I suggest to use an ethernet cable and connect the machine to your DSL router using the ethernet cable, while you use the Linux Mint live session and during the installation.
Once Linux Mint 19.1 has been installed on the machine, you should be able to follow JeremyB's instruction and make your wifi interface work.

I admit that the last time that I had to do so, run the installation connected to the internet via my ethernet cable, because the needed wifi driver was not included on the installation medium, was when installing Ubuntu 10.04 on my Zotac and on my Acer Aspire D260 way back in 2010. Yet, doing so worked.
(Later Ubuntu and Mint releases brought along the needed wifi drivers on the installation medium.)

Best regards,
Karl

Thanks, Karl, yes, at least I can complete testing with the exception of Wifi. That's if I can find my ethernet cables.... :roll:

Karl, checking those instructions, it says "In terminal check mokutil --sb-state as Secure Boot needs to be disabled in BIOS, don't delete the Secure Boot keys".

Would this {whole procedure} work on a machine that has UEFI, not BIOS?

Hi, Cliff_G.

Indeed the instructions which are about checking the state of secure boot and of making sure it has been disabled, these instructions are for UEFI machines only.
