Many thanks to alarconj! I finally got rid of interferences between my bluetooth mouse and my portable 4g router!
Just entered echo "options iwlwifi 11n_disable=1 bt_coex_active=0 power_save=0 auto_agg=0 swcrypto=1" | sudo tee /etc/modprobe.d/iwlwifi.conf > /dev/null and rebooted. I was affected by this bug running Ubuntu 15.04 with these peripherals: Asus U36SG - Dell WM524 - ZTE MF90 -- You received this bug notification because you are a member of Kernel 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?
