I recently purchased 4 Inspiron 660 destkops with Windows 7 x64 Pro. When I plug them in to an ethernet connection, they are able to pull an IP address from DHCP but they do not connect to the internet. The network icon in the taskbar has a yellow exclamation point and has the message "No Internet Access" when I mouse-over it. I am trying to connect the computer in an office with a DHCP server. I have not joined the computer to the domain yet. I can plug any of my other computers into the same ethernet port and they will connect to the internet including other computers with the same OS and computers with XP SP3 or Vista. I have also had another tech connect the computer to other ethernet ports that we know work with other computers and the computers still cannot access the internet.
I have already tried the solution here: http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/no-internet-access-wireless-routernetwork/681f02bd-509e-4dfd-b527-90f671489103 which advises you to uninstall the free McAfee software (which was already done or the computer didn't come with it) and uninstall a windows update which we did. The computers still do not connect to the internet. Are there any other possible solutions? These computers are straight out of the box and unaltered other than removing the software and update in the above link.
Could this have anything to do withi the Atheros Smart Net software or the Intel Trusted Connect Service Client? I'm not familiar with this software or what it is supposed to do.
