[Bug 219057] Re: Bluetooth does not coexist with WiFi

[ockels]

Stumbled across this bug installing 14.04.4 on my new HP 14-ac181 low-budget laptop.
First of all my wireless had unusable signal strength. After fixing it with the following code:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get install rtlwifi-new-dkms linux-firmware rtl8723au-bt-dkms
echo "options rtl8723be ant_sel=2"  | sudo tee /etc/modprobe.d/rtl8723be.conf

Wireless & BT worked.

But Wireless & BT do not coexist together. The following things happen:

- Without an AC adapter BT does not discover any device
- With BT & Wireless both enabled BT is very slow (eg: A2DP sound gets choppy and out of sync) + my wifi speeds are unusable
- With eth cable, AC adapter and wireless disabled BT works like a charm

Expected behaviour:

All interfaces should work together.
