Based on review, this router does not support vlan tagging. future firmware updates might be, but not too sure..

Anyway to work around it? I've been hearing something called Bridge mode but I'm not sure what it means or how it works.
Would really love to get the DIR 890 at the It Show as it's selling for $339 instead of getting a repeater and not getting the speed I want at dead spots around the house.
