If your computer was using a combination of working DNS IPs and your Belkin router's IP, it's a plausible explanation for intermittent outages. So if you had 8.8.8.8, 8.8.4.4, and 192.168.1.1, 1/3 DNS lookups would time out. Specifics are up to your operating system and lookup configuration, but you would almost certainly notice the problem, even if it was just minor annoyance. Lookups will usually be retried after a few seconds, so it might have just seemed like everything was extra laggy.
