network card buzzing

network card buzzing

[Pedro Venda]

hi everyone

I tought it was normal to have a buzzing on the network card while it 
transmits/receives high quanitities of data and using almost all of it's 
bandwidth... I had such a network card on my desktop and now my laptop does the 
same.

the laptop is a (smart-battery powered) acer travelmate 4001 WLMi and the 
network card is a broadcom (b44) 10/100Mbps.

after rejecting the idea, I decided to try the same on another OS... windows. it 
doesn't buzz while transmiting/receiving at 80Mbps whereas on linux it does. one 
can hear exactly when there is activity and when there isn't.

is this a problem? hardware issue? software issue? acpi? plain bad luck? what is 
happening here?

regards,
pedro venda.

I have exactly the same laptop, never heard any buzzing, not with LAN or WLAN.

wlan doesn't make any buzz...

issue. we all run gentoo.

Sining capacitors? See archives. idle=poll should fix it (evil grin).

Now you couldn't have possibly meant 'sinning'? (even more evil grin)

You are right, I meant "singing capacitors". I tried to look "sinning
capacitors" using google, and it really was not helpfull.
