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. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/219057 Title: Bluetooth does not coexist with WiFi Status in bluez package in Ubuntu: Confirmed Bug description: On my system bluetooth and wifi are unusable together. I have a built- in CSR-based bluetooth module in my laptop, and an Atheros wifi. Wifi transfers slow to a halt whenever there is BT traffic. For example, if I play a music file from another machine through the network using a BT headset, only the first few seconds of the file will play until the player runs out of buffered data. No further data is downloaded. Web pages also do not download, and I even lose connection to AP from time to time. At the same time, it looks like AFH is trying to work. If I monitor the value returned by 'hcitool afh', it changes. But this seems to have little effect on connection quality. Is this a problem with my hardware, or the AFH implementation? Is there a way to force bluetooth to not use the channels in use by WiFi?
