I ordered a TP-LINK TL-WR842N from a ZOL.CN seller. This is a known good router for DD-WRT. After a week during which nothing happened, an Asus RT-N12+ router arrived. I guess they were out of stock, never updated their seller page, and just sent whatever they could find.

I am trying to find if this router is supported by DD-WRT. However, it is impossible to search for the "+" character. I just get results for the RT-N12 which is supported. However, as DD-WRT is highly dependent on hardware I can't tell if the RT-N12+ is supported. If it's not I'm going to return it and complain to the seller. Thanks to anyone who can help!

According to this it's not supported http://www.dd-wrt.com/wiki/index.php/Supported_Devices#Asus

Fwiw, the N12+'s are MediaTek devices. Another option versus the hassle of trying to return it, though the TL-WR842N is prob much better...
There is Padavan f/w (I'd never heard of it 'til now). See these:

Thanks! I didn't know about this Padavan, but it is its own distribution. According to the developer, the RT-N11P software works on the RT-N12+ hardware. I installed the mod via the router's upgrade interface, hard reset for 10 seconds, and presto it's running the new software. Of course now it's giving CHAP authentication failure with the exact same username and password, but that's a different issue. Amazing! Thanks a lot everyone!

I had looked on the old router to find its MAC address, and copied this to the new router. However, the old router had already had its MAC address copied from the router that it replaced. Luckily browsing through the settings, I found that it had been changed. I changed the MAC address in Padavan and it matched the MAC address registered with my ISP and CHAP authentication passed. I love my new router and I didn't have to return it (too much hassle all around). Thanks to everyone who helped!
