Surely it should work?

I'm not very impressed with the Acer Veriton X2610G. As delivered, new, it doesn't work! The onboard network adaptor - though correctly installed - does not work when the machine is first started. After a reboot, it works. I have written a DevCon script which uninstalls the device and then reinstalls it, when anyone logs in. This fixes the problem - but, errm, aren't newly purchased items supposed to work???
