Since 2 months I have the following problem: the first time each day I power on my computer I cannot get internet access. I cannot reach the networkcenter to check if anything is wrong. Sometimes after a long wait (10 minutes) I get the alert: network adapter is not available. The only option is to power down the computer and to power on again. Usually then I have internetacces. I have run all kinds of diagnostics on the dell site but when internet acces is working nothing seems to be wrong. I have a XPS dimension 8300 with a Broadcom Netlink Gigabit Ethernet adapter
