I have made edits to this post and Wi-Fi works now, but I still have problems with Bluetooth, and is further explained below at "EDITS:"

A verbose output of lsusb has been posted down below, please tell me if I can get more info out of this. It indicates that Bluetooth is under Chicony Electronics.

Note: I have added another bounty on this question as I still have this issue with Bluetooth. I would like to have my internal Bluetooth working to reduce hassle with USB devices. I recall browsing answers which includes converting and editing specific driver files from Windows so I can use it with Linux and would like to do that where possible, but I lack experience with it and would love an answer that guides me through.

Original Question

I've got everything working on this laptop except for two tiny wee things:

  1. Bluetooth is not functioning correctly: it does show up in the tray, I can turn it on. When trying searching for a new device, none is found, and my other devices are unable to find my laptop either.
  2. Wi-Fi does seem to work, but after some time this becomes unstable: I'm unable to connect to any access point anymore until I restart my machine.

I have been searching on several forums and on this website, but I honestly do not have any idea what specific model I have for Bluetooth & Wi-Fi, and am unable to determine what drivers I need for this. I do know that the manufacturer of this Bluetooth device is Realtek.

If you would like to help me, I'd gladly appreciate it.

I have installed the Wi-Fi driver from source from here. I tried to install the Bluetooth driver with these files and make, but they do not work. Does anyone know the solution to Bluetooth?

    You can fix Wi-Fi by this solution. Regarding BT it should work with this kernel. If not I will look into it. – Pilot6 Apr 25 '16 at 16:23
  • There is no BT package for 16.04 in that PPA yet. I am not quite sure it is needed. – Pilot6 Apr 25 '16 at 16:25
  • And also I am not sure that there is BT in this laptop at all. – Pilot6 Apr 25 '16 at 16:30
  • BT won't work, but Wi-Fi should become stable. I will wright an answer for BT. – Pilot6 Apr 25 '16 at 16:40
  • I have added more edits to my question – Reboot Apr 26 '16 at 9:57

I would buy a new mini-PCIe Wi-Fi card (30-50 bucks) if I were you. Lot's of good ones out there. If you want to keep up on the bug reports for your card not working with bluetooth and flaky wifi you can read what others have tried and sign up here

  • Thus far your answer turned out to be most helpful during the bounty period, and therefore you deserve to have it. I will consider purchasing a new adapter if the bug continues to prevent me from using Bluetooth. The link you provided to me also allowed me to get a further insight on this bug. Thanks for willing to help. – Reboot Aug 24 '16 at 15:31
  • @Reboot - my pleasure. – WinEunuuchs2Unix Aug 24 '16 at 23:24
  • @Reboot Bumping an old question; did you replace the Wi-Fi card in the end? I heard this might be prevented due to BIOS whitelisting. – amees_me Oct 27 '17 at 14:23
  • @amees_me I've replaced my card and it's working just perfectly fine for me. Could be because my laptop had FreeDOS on it, so I'm not sure about the OEM Windows 10 versions of the laptop... Chances might be that there is better kernel support for this adapter now but you'd have to upgrade your Linux kernel manually for that. – Reboot Oct 28 '17 at 15:09
  • @Reboot Interesting! Many Lenovo laptops have BIOS-whitelists preventing you from changing the Wi-Fi card. What card did you change to? – amees_me Nov 5 '17 at 12:55

Unfortunately Realtek shows nothing for an RTL8723BE, but the WiFi drivers for Linux can be downloaded directly from Realtek, here: Realtek PCIe WiFi driver page

Here is an AskUbuntu page which seems to solve the WiFi problem for this Reaktek card: Wifi problems with rtl8723be in Ubuntu 14.04

There was an answer which appears to have solved the bluetooth problem in AskUbuntu: RTL8723BE Bluetooth does not work

Those should solve your issue.

Respectfully, David

  • Unfortunately compiling this driver will result in a bunch of errors for me: /home/reboot/Documents/makedump/bt/rtl8723au_bt/btusb.c:111:14: note: each undeclared identifier is reported only once for each function it appears in And a lot more: btusb.c:114:12: error: ‘struct hci_dev’ has no member named ‘reassembly’ skb = hdev->reassembly[index]; ^ btusb.c:141:7: error: ‘struct hci_dev’ has no member named ‘reassembly’ hdev->reassembly[index] = skb; ^ btusb.c:163:10: error: ‘struct hci_dev’ has no member named ‘reassembly’ hdev->reassembly[index] = NULL; – Reboot Aug 24 '16 at 15:14
  • (Comment 2) I have stumbled across askubuntu.com/questions/607339/… before, though the same compiling error occurred before me posting this question on here. – Reboot Aug 24 '16 at 15:32
  • Your lsusb result does not show a Realtek usb bluetooth device and is likely why you received USB errors. Here is a discussion which seems to provide a manner to solve the problems some have with it: github.com/lwfinger/rtlwifi_new/issues/18 But Ubuntu uses an older version of Bluez which causes problems for some. You can download the latest Bluez file here: bluez.org/download But the fact that it doesn't show in your lsusb results is a concern. – monkeyman_stones Aug 25 '16 at 0:20
