I'll be getting my NBN connected in a few weeks and it seems like a good time to retire my old WRT54G routers.
Does anyone have a suggestion for a router that is:
cheap
reliable
802.11n dual band
easy to put OpenWRT on
I'd highly recommend the RT-N66U.
There's a newer version now as well with 802.11ac but that's more expensive.
I don't know about OpenWRT but I'm a TomatoUSB user and it was a breeze to put Tomato on it. Fast 600 Mhz Broadcom CPU with lots of RAM, 4 GigE, 3 Wifi antenna and so robust and reliable, it has not rebooted on me once in over 1 year of usage.
As for NBN compatibility, these are just routers and as long as your modem supports NBN and then you configure it for passthrough, the router will just work with whatever connection it is getting.
I used to be with iiNet and they used to support it fine, they're engineers actually appreciated the unit. I've since switched to Internode and those guys are also fantastic in support.
