Boa noite, estou encontrando problemas ao conectar qualquer dispositivo bluetooth ao notebook, pois está ocasionando lentidão na conexão de rede usando o wifi.

Realizei teste de velocidade pelo Google, eis os resultados:
Com bluetooth conectado: Download 0.79 mpbs
Sem bluetooth conectado: Download 14.4 mpbs

Por pesquisas encontrei algumas soluções válidas para outros usuários, mas que não se aplicaram no meu caso, são elas:

1. Salvar em /etc/modprobe.d/iwlwifi.conf ----> options iwlwifi 11n_disable=8 bt_coex_active=0 e depois executar o comando modprobe -r iwlmvm || modprobe -r iwlwifi || modprobe iwlwifi

2. echo "options ath9k btcoex_enable=1" | sudo tee /etc/modprobe.d/ath9k.conf

3. echo "options iwlwifi bt_coex_active=N" | sudo tee -a /etc/modprobe.d/iwlwifi.conf

Sou iniciante no linux, portanto não sei quais informações seriam aptas a ajudar a solucionar meu problema, sendo assim estou a disposição para fornecê-las.

Obrigado!

O Bluetooth e o Wifi usam frequências diferentes. Então não deveria causar interferência.

Ao que atribui então essa perda na conexão?

esse procedimento eu já tinha realizado para habilitar o bluetooth, que não era reconhecido no sistema quando instalei.

Encontrei a solução em:

https://askubuntu.com/questions/791785/qualcomm-atheros-bluetooth-4-0-not-working-on-ubuntu-16-04

After fiddling with this problem for quite some time, I found this solution:

I installed linux-generic-hwe-16.04 to get a more recent kernel, because 04ca:3014 was added in version 4.6.

Then I noticed that ID 04ca:3014 Lite-On Technology Corp. was being disconnected after loading acer_wmi, so I blacklisted it:

/etc/modprobe.d/btconfig.conf:

blacklist acer_wmi
(Also, I thought it better to add btcoex_enable=1 and bt_ant_diversity=1 to ath9k in that same file: options ath9k btcoex_enable=1 bt_ant_diversity=1.)⁽¹⁾

Then I ran update-initramfs -c -k all, I rebooted the system, and voi-là, the adapter is up and working.

Somente alterei a instalação desse
