As I understnad it, the difference between the WNDR3700v4 and WNDR4300 is t= hat the 4300 has a slightly better wireless chip.

Unfortunantly from what I've seen so far, they did something wierd with= the storage and as a result the stock openwrt can't access it. I'v= e seen reports of people getting it to run from an initramfs, but this mean= s that no settings can be preserved across reboot.

If you've seen anything different, I'd be very interested to hear a= bout it (I picked up a 3700v4 and a couple 4300's for testing)
