Network Card not being found (Ubuntu)

Hello,

I just received my Chuwi Herobook Air today and I am super excited!

Serial #: HeroB AQ128G21082495

I installed Ubuntu (Ubuntu 20.04.3 LTS) on it and things seem to be working fine, with the exception of the networking options not being found. Looking in the config, seems like my networking card is not being recognised.

So, I am guessing, it’s a drivers issue.

I looked through the internet and your forums and see that some drivers are made available:
These ones don’t seem to be the right ones for my card.
These ones are for Windows.

Can you help me locate the right drivers for Ubuntu and perhaps run me through how to install them?

All the best,

Theo

I don’t have a herobook so have no idea what the available cards are, but if you post the output of lspci I may be able to assist.

Thanks @tlmiller76 !

Which one is the culprit ? :slight_smile:

I ran lsusb and found the name of the card:
ID 0bda:d723 Realtek Semiconductor Corp. 802.11n WLAN Adapter

Found these drivers but when I go to install them, I hit a deep mesh of missing dependencies in Ubuntu. I tried installing them individually, one by one, but it keeps going deeper and deeper.

I ll keep at it tomorrow.

OH wow, what a horribly archaic and trashy wireless card. Do you have any alternative way of getting online for a few minutes? There’s a PPA that has working versions of the drivers.

Turns out, connecting the phone by USB to the computer and using it to tether allows you to have a connection going (helps for dependencies)

Ok, we’re getting somewhere! :slight_smile:

@tlmiller76 , I added the PPA you suggested, then ran the drivers troubleshooter from the Software & Updates > Additional Drivers and Ubuntu suggested using rtl8723du-dkms

Remains to be seen if this is successful.

Thank you so much for your help so far guys/gals!

Update: it worked!

Pretty impressive of the drivers trouibleshooter, that is INDEED the package that’s needed for that chipset.

Thanks for your help on this guys!
Now, onto the sound card, which is also not recognised :smiley:
