Hi, I just bought an XPS 8300 brand new. After woeking OK a few days, now it connects to the Broadcom Netlink Communication card only after rebooting 3-4 times at cold-start. Anybody experiencing the same problem? All the other home computers are connecting from the first shot. (two laptops and another desktop. They much slower computers. At the begining I have re-installed the driver (from DVD and downloaded), but not this is the problem. The computer has to get a bit warm. When it does not connect, the Dell Test tool DOES NOT SEE (does not appear in the test list) the Broadcom NetLink Gigabite Ethernet card. I am a bit dissapointed, it is a brand new computer, I expected more than problems from the very begining.   Thanks, Cristian, Montreal, Canada
