Recently replaced a 1700 series router from Bell with an 1800 series router from AT&T, bother managed by them. Periodically my attached PIX needs to be reloaded (i.e. rebooted) to enable new computers on the network, with any OS (2000 to Vista) to have local and internet access. For some reason they only have local and the reload fixes the issue for a while longer. AT&T has no idea.
