I've had this router for over a year and the results have been very good. The router plugs into my ISP's wall jack in my 400 unit apartment. I tested this in mixed mode and it worked fine, however I have chosen to deploy the router with N-only as all of my neighbors have G routers and I wanted to operate on a different frequency. I've got N-wireless on my laptop, have set WPA2 + AES, which is what you need to use in order to achieve maximum speed. Don't use WPA+TKIP or WEP unless you have no choice.Running Windows VISTA and the connectivity has been very good. I have had one occassion where I couldn't connect to the router and the odd thing is that I couldn't figure out why. Oh well, I'm going to buy another as a spare.
