[Cerowrt-devel] wrt1900ac v1 vs v2

There are refurbished wrt1900ac units available quite cheap ($10 or $20
more than wrt1200ac).  I assume that they are v1 units as the v2 units have
only been on the market for a few months.  From lurking on this list I get
the sense that these will support full sqm in short order (correct?).

So what are the differences between wrt1900ac v1 and v2?  Is there any
reason to pay nearly $100 more for a v2?

There is an active discussion of the WRT1900AC routers at the OpenWrt forum. That would be a very good place to ask this question.

v1 has Armada XP chipset which has packet accelerator HW in it that 
OpenWrt doesn't use. v2 has Armada 385 which doesn't have a packet 
accelerator, but instead has a much better CPU for forwarding packets.

So basically if you buy a v1 you'll get a third or so in forwarding 
performance over the v2 with OpenWrt. With the Linksys firmware I could 
imagine the v1 is faster than the v2. The v1 has a fan, v2 does not.

Shows a v2 with 512M of memory, actually purchased.  I would think that the 512 is definitely useful.

From watching the openwrt discussion, it looks like 1900v2 and 1200 share the 
same driver, which has direct openwrt support from the vendor while 1900v1 had a 
closed driver that there was later a source version discovered for.

I would expect the future support for the 1900v2 and 1200 to be far better than 
the 1900v1 (especially as supplies of them dry up)

so the question is if 3x3 gives you enough value over 2x2 to make it worth 
getting a 1900v2 instead of a 1200
