I'm having oneplus Bluetooth earphones and when I connected it to my system the internet speed drops rapidly and even you tube won't work.

other apps like web-apps like MS teams, gmeet, Zoho call nothing works on Bluetooth

If I just replace Bluetooth earphone with wired earphone internet works lightning fast.

In previous Ubuntu 20 LTS version I didn't faced this issue. but, after upgrading to 22.04.2 LTS I'm thinking why I did this mistake.

Edit: updates installed now even with new upadted kernal upon connecting bluetooth MS teams or Gmeet get disconnects and it will not work.

Try disabling wifi power management with `sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf` in terminal. Can you switch to using wifi on 5GHz?

@Jeremy31 nothing happened. my wifi router wont support 5G. it's normal one. also in ubuntu 18 or 20 lts version I never faced this issue. i.e internet calls not working upon Bluetooth connection.

@VikasAcharya you're missing a leading `/` on that path. Jeremy didn't include it, and it's required.

It looks like there is no way to adjust the Bluetooth coexistence with ath10k

I don't know if using an older Ubuntu version will help. The problem is that wifi and bluetooth use the same frequencies and can interfere with each other

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
