Sounds good. The AC mode is not displayed on the UI, it's hidden however seems to be active when using "Mixed mode".

I saw good operation with BGN mode and WPA2 Personal only as well using current FW version.

Thanks for clarifying and confirming that under ordinary circumstances Mixed Mode and B/G/N are identical. I do not see AC mode in my WPA2 Personal 2.4 pulldown, so I should be okay. I switched from the default WPA2/WPA Mixed Personal to just WPA2 Personal as suggested and everything's been rock solid with the initial firmware.
 
I've seen some people in the DD-WRT forum indicate that they purchased a 1900ACS and it's badged "V2". So far haven't found any official confirmation...
 
I'm not talking about the fact that the AC V2 and ACS appear to be identical.

I'm talking about people in the DD-WRT forum posting that they have in, their possession a WRT1900ACS V2, meaning a 2nd version of the ACS and a 4th version of the router overall.
 
I can't find any proof that it actually exists, though. It's certainly not documented anywhere on the Linksys website.
 
I'd be suspicious of users posting and mis-understanding of ACS v2. Possible confusion of what sticker really means.

Hope it's not true this early in the product cycle. 'Cause then I'd be really unhappy about the rebadged 1900ac v2 thing :(

Well the WRT1900AC was pretty much a fully-developed product at the time of the Belkin buyout. Belkin seems to be iterating hardware in order to cut manufacturing costs, so it's not real surprising.

Buyout was completed in March, 2013; 1900ac v1 was released in April, 2014.
 
Right. The platform itself likely had a 3-year development cycle, which means it was 2/3 complete when the buyout was finished. Figure in 12 months for synergies/integration and you're looking at Belkin monkeying with the hardware manufacturing process after the initial release.

Actually, from what I can tell thru various docs, SW development started around May, 2013, probably on a marvell HDK, with early mamba integration later in the summer...

RTM software code - production ready was Mar 2014, so this put final Production Definition right around late April, early May 2013... little bit longer dev cycle due to merge of the Marvell SDK into the Linksys mainline...
 
So they literally threw it together right after the merger. That would certainly be a plausible alternate explanation for the hardware iterations...

My guess is that it was on the product roadmap - but green lit post Belkin purchase - hence the development start back then... remember the disk expansion chassis that was announced (and cancelled) which actually explains why the eSATA port was present (connectivity to the chassis) - circa 2013, the WRT1900ac V1 was comparable horsepower wise to the Marvell based NAS boxes...

If I'm reading this right, it's saying it's a 1.6 processor.

Where do you see the CPU speed? I do not claim to know what I'm looking at but here is the same snippet from my 1900acs sysinfo:

Decent router but won't give me my 200Mbps speed on the both bands. Most I get is 160Mbps. The RT-AC88U gives me 230Mbps on both bands.

Well, after all, the RT-AC88U is rated #1 in its category here. On the other hand, it's the only router in its category *smile*.

Not reading it right...

Mamba is 1.2GHz (1900acV1)
Cobra is 1.3Ghz (1900acV2)
Shelby is 1.6GHz (1900acs)

They all perform about the same - the ACS has the higher Tx levels in 5GHz as per FCC rules..
