Bluetooth slows WIFI

[wosco]

Helllo All

Is it normal when using Bluetooth that your WIFI speed drops dramatically.

I am using Mint 19.3 on an Ideapad 530S when I use bluetooth to play music the speed drops to a tenth and music sometimes staggers.

Thank you I'll give it a try

[wosco]

Turned of Power Management but it had no effect. WIFI is still really slow while playing music via bluetooth

Ok, everything is unblocked & power management is off. That's all I know to do. Perhaps someone else will jump in here.

[wosco]

Thanks anyway

[jaundice]

try replacing default bluetooth applet with Blueman and then quit the default one , and start using blueman

Code: Select all

sudo apt install blueman

if the wifi speed is still down try removing bluedevil

Code: Select all

sudo apt remove bluedevil

good luck

[wosco]

Hi jaundice

Installed blueman and disabled bluedevil but the speed is just as slow

Thanks

I was going to say I already had that installed, but on checking I had the previous version from 2018. I installed this new one as per instructions and it appears to have fixed it.
I'll keep you posted

Thanks
wosco

[sleeper12]

Interesting, I deleted that post because I thought you already had it. Now maybe it fixed it after all.

[wosco]

Yeah it's funny, it's intermittent, sometimes I get 80% speed other times it's about 35% but it's much better than prior to the new version as it was constantly very slow.
Obviously whatever was done in the new version has helped this issue

[sleeper12]

Ok, at least it's an improvement.

Glad it worked ,in order to get the most of blueman, consider updating python to at least 3.6, (or better 3.7),
also if you have control over the router , try switching the channel ,

[wosco]

Jaundice

I've switched from channel 6 to channel 2, this was worse so have now gone to 5. I am presently on python 2.7.17, are there any issues going to 3.7?
