yoga 3 - bluetooth does not work; must choose between wifi and bluetooth

Have you used a wired connection to get fully updated?

I suggest you report a bug

yes, it was updated

14.10 is EOL in 2 days and will cease to be supported in any way. I suggest you update to 15.04 asap

okay, let me see
thanks!

What is the wifi card? Post the result of

lspci -nnk | grep -iA2 net

wifi works now with the 15.04., still, it freezes the system quite a few times when I switch from one network to another

the network card is
01:00.0 Network controller [0280]: Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter [14e4:43b1] (rev 03)
 Subsystem: Lenovo Device [17aa:0623]
 Kernel driver in use: wl

bluetooth seems to work as a tool, still,
. it finds my envaya denon bluetooth speaker
. but it can not connect to it
same with my phone

What is the result for

dmesg | egrep -i 'firm|blue'

happiness@happiness-yoga3:~$ sudo dmesg | egrep -i 'firm|blue'

Thank you!

Why did you add sudo? Jersey's command in #9 doesn't have the word in it, so why did you add it?

because I am a new user of ubuntu, and when I was browsing on the net on how to do things, it always starts with a sudo; also, they many times leave it out (and expecting to add). this is why, factually. emotional wise I did not mean to hurt anyone with it, I was happy for the feedback and that it proceeds, so I hope I did not cause many disturbing feelings with it, and if I did, what to do..
Jeremy I hope everything is fine with you.

the response for the command as it was given is exactly the same:

happiness@happiness-yoga3:~$ dmesg | egrep -i 'firm|blue'

Adding sudo is not always needed, sometimes adding sudo to commands can do damage to files.

Please run commands given by helpers as given. Don't add sudo just because you think it's needed / because you feel like it.

What is the output of:

hcitool scan

If you set your device to be discoverable. Is it seen? Do you find any Bluetooth devices at all?

okay, I will not do.
this was a learning curve,
many thanks!

the result is

happiness@happiness-yoga3:~$ hcitool scan
Device is not available: No such device

it recognised deviced an Envaya speaker, but it did not manage to connect to it with any of the PIN options. My other laptop and phones recognised this Envaya device easily. Same with the headset.

Now it does not recognise it anymore (I have a bluetooth mouse, a headset, a speaker and a phone switched on next to me). I was waiting quite a few minutes expecting the search to give any results.
The search slows down the laptop very much, I can hardly write this text. After stopping the search, the computer is fast again.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Installed all of new updates, problem still persists.

Installed all of new updates, problem still persists.
