Networking sucks

Can anyone explain this to me ?
Every time I start using the internet from my Ubuntu Linux thing, my wife starts making funny noises.

It's true. I checked the manual (spoke to my father-in-law !) She's alright.

The Wireless network gets totally overloaded when I start my browser.

Half the time my netcard is Idle, but the router is still working so hard that it makes my wife say §@$¤£~!

When I decided to install Linux I knew I would face some serious trouble. You know, all the things they are writing articles about on the internet. But I seriously never expected to hear funny noises from mrs. caused by this.

It's a Jensen of Scandinavia Air Ling WBR 6954 with firmware v1.4.3.C
