Hi guys how are you?
My new 87u is interefing with my Phillips bluetooth headphone, the sound pops a lot
With my old 68U i never had this issue, anything that i can do to fix it?
Thanks

Is there a option in the 2.4 radio setting that sets Bluetooth coexistence? I know in Tomato their driver supports it and I used to use it so because my mouse and keyboard were Bluetooth and I would have issues with them keeping connections.
I don't think so
Merlin, is there this option in your FW? Or at the professional tab?
I'm not in front of the router right now
Tks
Bluetooth uses the 2.4 GHz band. Try using a different channel on the 2.4 GHz band.
Bluetooth spectrum use
Bluetooth defines 79 channels for communication on the 2.4 GHz band each channel being separated by 1 MHz. The frequency range used is between 2.402 GHz and 2.480 GHz. Bluetooth's transmitted signal is spread across this 2.4 GHz band and the specification allows for 1600 frequency hops per second, the advantage being that since information is spread across a wide band of frequencies signals transmitted by other systems using a portion of the same frequency spectrum may appear as noise to only some of the frequencies used by Bluetooth device using frequency hopping and similarly only a portion of a Bluetooth transmission may interfere with signals transmitted by other systems.

Interference
Each 802.11 channel then equals to 20 Bluetooth channels. When communication is enabled on an Bluetooth device you will get interference when the Bluetooth device hops on to any of the 20 Bluetooth channels equivalent to your 802.11 channel. Even if a Bluetooth device hops at the max allowed frequency rate of 1600 frequency hops per second there are only 79 channels available so at this rate each channel will be used around 20 times in a second.
Change the channel to only 40mghz will make some difference?
My Beyerdynamic Rsx700 is clicking once per second while 2,4GHz is on. There is nothing we can with this interference.
Here is some info I dug up
from here
and more info
more info
hp info on it
finally the google search I used
Please let us know what you find out.
Edit: It seems, if I am reading what I posted above correctly, wifi channels 13 and 14 do not have bluetooth on them.
No, I'm on RT-N66U and was on RT-N16 before. Both routers causes interferences while 2,4GHz band is online.Are you using the 87U as well?
It was not happening with the 68U
No, I'm on RT-N66U and was on RT-N16 before. Both routers causes interferences while 2,4GHz band is online.
But we can select untill channel 11 at the router
