Query: Another defective unit

The DIR-450 seemed to work at first, but within 1 hour it went into power reset/cycling over and over. Hard reset, power off/on, nothing worked. D-Link tech support worked with me for 25 minutes and gave up. He said the unit appeared to be defective and told me to return it to the store (Fry's).From the other postings, a DOA unit seems to be way too common. I am looking for a different manufacturer now.
