I'd had an 802.11n-capable router for a long time but as I discovered it wasn't connecting in n-mode. Installing the Asus router and having the ThinkPad T420s connect in n-mode made a believer out of me.
I never got my Actiontec PWR500 Powerline Ethernet adapters on the same phase so the TiVo in the bedroom continued to complain about network speed/connectivity.
I had an electrician in on another project and I asked him to give me a bid to drop Cat 6 Ethernet at each of the TiVos. His estimate sent me looking for alternatives.
I bought a pair (one for each TiVo) of Asus EA-N66R adapters. The installation was incredibly easy. The default configuration is an Ethernet bridge. All I had to do was choose the SSID and enter the pass phrase. While I was at it I reflashed the firmware.
How'd it work?
Here's the speed test using the Actiontec PWR500.
Yeah. Not good.

I think that this is actually limited by the Comcast Internet connection and that the 802.11n WLAN connection is faster than 30Mbps.
