Hello.

I can notice that on my Gentoo, my Internet connection, with WiFi, goes down very very often, more than usual. For example, I'm also using Arch Linux. On Arch Linux, Internet goes down three times during a day, due to an IP change. But on Gentoo, Internet goes down three times every half hour, more or less, and with no reason.

And if I emerge something or do something that needs Internet connection, it's very annoying.

Hi Ignatius881,

could you post your /var/log/messages ? Or any relevant part(s) in this file, when your WiFi is disconnecting ?

Also, are you using the same WiFi module on Arch and Gentoo ? Same kernel on both Linux distros ?
What WiFi card model do you use ?

Good luck :]

Both on Arch and on Gentoo I've blacklisted this modules: rt2800usb, rt2x00usb and rt2x00lib.

The kernels are not the same. On Arch it's 2.6.37-ARCH, and on Gentoo it's 2.6.36-gentoo-r8.

My usb is a conceptronic c150ru.

EDIT: I was thinking about something. Maybe my connection is/was unstable due to a program emerge (firefox, networkmanager, wicd...). Because I was using Gentoo during a whole hour, and the connection didn't go down yet.
