Got mine setup, only had a couple of small issues with doing so to my liking.
1. It's having trouble establishing a connection automatically with the ISP after reboot or power cycling. If I login to it and tell it to Renew the connection to the ISP manually it always works. I can deal with that easily enough for now with a simple script, not sure if it's down to my ISP or the firmware.
2. By default the FTP server port 21 on the device was Closed on the WAN side (not running/Open, but responding to requests by closing the connection). A quick port scan showed this up, and turning off the FTP server in the device didn't cure it, so I did what I always do with pesky ports, and forwarded them to a dead IP on the LAN, happily stealthing it again. This is something you need to do with routers that respond to IDENTD (113) requests with a Close, so I always check for things like that. Just wasn't expecting it to be on a service like FTP though.
Those things aside it's providing stonking wireless (best dB I've had compared to other previous b/g/n wifi routers) and a stable net connection - something I've been sorely missing for a while.
