You do not need to worry about those errors. Two other drivers in your system, lp8755 and dt2817, are messed up, but they will not affect your wireless.

The warning during the build can also be ignored.

thanks for the reply... and now I can follow the readme.. no? many thanks

[lwfinger]

I thought you were following the readme.

[NVG2021]

yes, i did, just stopped with the errors, will proceed so, when last input for blacklist is done, reboot?

[NVG2021]

I've rebooted but the wifi does not show on the network options..... one thing I've noticed is that my device number does not match with what the readme.md file says... Mines is Bus 001 Device 003: ID 0bda:d723 for a Realtek and on the readme it says 0bda:b720 almost the same, but different number at the end... any hint? Many thanks again

[lwfinger]

The USB ID differs only by 3 at the end, but 0bda:d723 is for an rtl8723du, not an rtl8723bu. You have installed the wrong driver. Use git clone git://GitHub.com/lwfinger/rtl8723du.git -b v5.13.4 to get the correct one.

I am closing this issue. If you still have problems, open a new issue in the rtl8723du repo.
