WiFi speed drops significantly while using Bluetooth TD-W8961N
Hi!
I got TP-Link TD-W8961N. My ADSL connection is stable 20 Mbps.
But every time I use Bluetooth headhones or transfer files with Bluetooth download speed drops immidietly from 2500 kB/s to ~200 kB/s. And goes up to 2500 kB/s immedietly after pausing audio on Bluetooth headhones.
Its not problem with devices using Wifi, but with router instead. I tried it with different phones, laptops, PC and couple different Bluetooth devices, results same: Wifi speed drops similarly. l tried other routers from ZTE and D-link and they dont affected with this problem, internet speed stays stable.
I tried changing wifi channels 1-11 and width of channel from 40Mhz to 20Mhz it had no affect. I changed signal strengh and type b/g/n it had no affect. I tried using bluetooth devices near routed or phones, laptops and speed wasnt affected. Speed of wifi drops only when using wifi/bluetooth on same device.
My ADSL line parameters:
Also Wifi Tx error count and Tx drop cout goes UP
So what should I do?
