Running a 1900ac v1 and upgraded hoping it'd fix my reboot issues... I've been on a few betas and usually I'll have to go through a power down and 3-4 reboot cycles until mine comes up and is stable.. On the latest 33375 and still have 3-4 reboot cycles until it fully comes up...

any ideas?

There is a known issue with the WRT1900AC v.1 and the 4.9 Kernel that causes frequent random reboots.

The last stable build is 5/2/2017 - r31924
It was removed from the FTP site for another reason, but you can get it here:

Awesome... thank ya much. Once it's up it seems pretty stable but aggravating on the first boot

The stable build I am using is 24th April 2017 build 31899 as it doesn't lower the CPU frequency down to 600Mhz as the build from May does.

You can get it here.

ftp://ftp.dd-wrt.com/betas/2017/04-24-2017-r31899/linksys-wrt1900ac/

It seems that Linksys WRT 1900AC is only compatible with kernels versions from 3.10 and up to 4.1 (maybe). The April build runs kernel 3.18.50 that is now EOL.

I have the exact same version as you and I have tested the kernel 4.9 version. It does not work.

I’ve noticed on mine the CPU only displays 1200 MHz when under a load.

The last stable Kernel for the v.1 was 4.4, but I don’t think any of the DD-WRT builds has it. Brainslayer must have updated the Kernel several times between 31924 and 32170.

LEDE has a special 4.4 Kernel build for the WRT1900AC v.1 that you can get here:
