The brown out killed the power adapter or the router entirely?
I would recommend a DIR-645 or 657 if the parents aren't using 5Ghz.
No word on WRT support yet. Anything is possible at this point. I don't think DLink allowed any support on the DGL line though. Maybe the 5500 will be the first.
Killed it completely. Would power up fine, lights would show good connectivity, hardwired would show a connection, but no IP. I reset to default, went static but was able to ping the default gateway. I am going to try to reflash it but I think its a brick.
As for the those routers, Im still a sticklier for external antenna, so if I was going to go Dlink, I would probably go DIR-655 since thats more in my price point.
Last, reason the DGL has never hard 3rd party support is it needed the Broadcom processor for the Gamefuel processing and Broadcom has never been compatible with 3rd party firmware(with very few exceptions), unlike routers like the DIR-615 that has a Atheros or Ralink CPU which is much more 3rd party friendly.
