I have tried many commands and solutions but still the wifi drivers could not be detected by the software center in Ubuntu 14.04.5. I am using hp 15 bw096au powered by amd a6-9220. I will provide outputs of commands wherever necessary. Please help....Thanks in advance.

  • You asked the question previously, we showed you that the exact same wireless device was asked about and answered previously. Did you try the steps in the link? What went wrong when you did? The answer is still exactly the same. – chili555 Feb 8 '18 at 13:46
  • It did not work....I edited that question by adding my output – Kazi Fariadul Islam Feb 8 '18 at 13:48
  • "Still doesn't help" doesn't really tell us anything useful. Were there errors or warnings after any of the commands? Did you try a reboot? Are there any clues in the log? dmesg | grep rtl – chili555 Feb 8 '18 at 13:50
  • dmesg | grep rtl [ 11.878650] Bluetooth: hci0: rtl: examining hci_ver=08 hci_rev=000d lmp_ver=08 lmp_subver=8723 [ 11.878658] Bluetooth: hci0: rtl: loading rtl_bt/rtl8723b_fw.bin – Kazi Fariadul Islam Feb 8 '18 at 13:55

You have a few instances where a dkms module was added, but not fully installed.

sudo dkms remove rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414 --all

If there are any errors after any of these commands, STOP and post them here. Do not proceed until these errors are fixed.

If there are no errors, then do:

sudo rm -rf rtl8723de
git clone -b 4.10-down https://github.com/jeremyb31/rtl8723de.git
sudo dkms add ./rtl8723de
sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414

Then reboot.

Again, if there is any error, stop and tell us so we can fix it first.

  • The second command in your answer gave an error.... I've added the output in the question – Kazi Fariadul Islam Feb 8 '18 at 14:33
  • Would you like me to continue with the third one? – Kazi Fariadul Islam Feb 8 '18 at 14:34
  • Please see my edit above. I have amended the commands. Try again and stop if there are any errors. – chili555 Feb 8 '18 at 14:52
  • Only the last command showed an error. Result of the command added to question – Kazi Fariadul Islam Feb 8 '18 at 15:07
  • Is there anything you can do for the last command? – Kazi Fariadul Islam Feb 8 '18 at 16:33
