it as much as= =20 sending, though: downloads are mostly small, while the bulk sending happens= =20 regularly during backup.) It is not related to how long the WLAN is up: I can work for days or weeks= =20 (happened with earlier kernels as well) with this laptop, over=20 suspend/resume, and WLAN works fine. It's only when I run backup that it=20 happens (always - but I since backups usually are incremental, they're ofte= n=20 small enough. But once I do a full backup WLAN goes down. So use cable fo= r=20 those...) Is this known? Can I get you more information?
