The Netgear R7200 hardware is the same as the R6800, and the R6700v2. The R7200 labeled one was only sold by walmart from what I have seen, but the same hardware was sold under different model numbers by different retailers.
Back when I posted this https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=323445 on the R7200 openwrt was not very stable on it. I tried again late last month, and have been using openwrt since. I am using the R6800 firmware from the daily snapshot builds as there is no stable build support for this model. Yes, the LEDs are buggy, but I am not too worried about that.
The nmrp recovery process makes it easy to recover from just about anything, and can even be used to put alternate firmware on one of these new out of the box without using the Netgear firmware interface at all.
Thanks for the reply. I'll check that out. I did see some activity regarding the 6715 chip there also. I guess that's Mediatek's wifi chip on these models. It would be nice to get a stable release of this fw.
If I remember correctly, I found this router for $79 on sale at Walmart. From what I can find online, the same router is now selling for over $150. Seems like solid hardware. If I ever do find another one on sale for a reasonable price, I may just buy and donate it.
