Bug Description

On my Toshiba A110-228 laptop (PRO/Wireless 3945ABG network connection and Intel 945GM Express chipset), I close the lid and put the laptop in suspend mode. After waking up from suspend mode, on Edgy and on Feisty (Herd 2) everything works fine, except that I lost my wireless internet connection (DHCP). On Dapper, which I also use, everything works fine.
If you need more information / data files, please let me know.
