  1. I run Manjaro KDE on a DELL XPS 13 (model 9343) notebook that has an Intel 7265D wireless (+ bluetooth) card with linux-firmware version 20170309.695f2d6-1 .

  30. I face the following problem. When bluetooth is on (enabled) the link quality of some of my wifi connections becomes quite low. For instance, at work (router: Dlink Dir-809, 2.4 GHz) with bluetooth on I get link quality = 28/70 even though the notebook is two meters away from the wireless router.

  58. Using any of the following options (or some combination of them) does not help:
  59.  
  60. 11n_disable=1
  61. swcrypto=1
  62. 11n_disable=8
  63. bt_coex_active=0
  64.  
  65. Turning off wireless power saving does not help either. The problem does not happen when I connect to a 5 GHz wireless network, i.e., it only happens with 2.4 GHz connections. The problem is not Manjaro-specific. Prior to installing Manjaro on this machine I was running Antergos + Gnome and was having the same problem.
