Slow Internet speed on Vivaldi

[LassIV]

Hi!

I did a clean format on my computer to Windows 11 and after installing all drivers, softwares etc. I realized that my speedtest on vivaldi can't even reach 10mbps (download), while in different browsers (edge, chrome) it reaches the normal 50~100 mbps(download).

After a few tests I realized that it only occurs when I'm using the Youtube to play a song on the background.

I've tried already to:

• Restart my computer
• Deactived everything on my firewall and anti-virus
• Turning the VPN off
• Checking on mobile Vivaldi
• Turning off the extensions
• Downgrading my Wi-fi driver to a old version

I have run out of ideas, does anyone knows any alternative ?

@LassIV
Hi, disable extensions and AV software does not really disable them.
To check the first with a Guest Profile, some AV software has to be removed.
Which page do you use to test the speed?
I use https://www.speedtest.net.

@LassIV Please try the troubleshooting steps, including testing in a clean profile and disabling adblocking/extensions:

Tested in Vivaldi and the Zen Browser, I can't see much differences, some little fluctuations apart, Zen (Gecko) somewhat slower)

I've made more tests and realized it was my bluetooth speakers that was causing interference on the wi-fi.

I've tried to reinstall the driver but it didn't work, I've also tested different bluetooth device and it's the same issue... Seems like its a Windows bug

A strange issue.

I'm old school, I don't like Bluetooth devices, always cables. Safer and less problems
