Electrical noise coming from the receiver and slow internet speed #344
Description
I have TL-WN8200ND V2 device. When in windows the green LED blinks when in use. On Debian 12 bookworm, the receiver seems to behave strangely. First of all, it makes an electrical noise that is at least 10 times more loud than when it works in Windows (I did not notice before that it was even making a noise with 4 years of use you have to get your ear close to hear it in Windows), and the LED is not blinking but it is synchronized with the noise with its light level. It is like it turns on and off 200 times a second. I am sure that the noise happens when I start using the internet. As soon as it starts loading a website it starts the noise. Lastly it is slower than Windows11 at about 1/2 to 1/5 ratio both down and up. I have verified that our driver is set up properly with sudo lshw -c network. It shows the wireless interface is using it driver=rtl8192eu driverversion=6.1.0-25-amd64. I have checked all relevant issue pages but could not resolve it. More importantly may this mean hardware failure?
