Query: Does not deliver stated speeds, unreliable

I purchased this item based on the highs review here, but I am disappointed and regret my choice because it does not deliver the stated performance levels reliably.This router is easily overloaded and struggles to deliver the full N speeds across the wireless network. This results in stuttering web video streams, poor file transfers which hang part way through, and a need to restart the unit every few days to restore performance. It's worth reading the dlink support forums to see what others say about this router -- it sounds like many users have the same issues with the dir-655 that I do.I'm switching back to my 6 year old 802.11g router, which had no issues at the same usage level.
