Just purchased a r7800 and flashed DD-WRT 4.9 v3.0-r37120M kongat (10/03/1 without problems.
However, I have had intermittent but almost daily connection drops (losing IP?)..sometimes just with ethernet connections (wifi still connected). This morning however both wired and wifi had dropped - instantly back up after loggin into GUI and "applying settings" but not changing anything otherwise.
In an attempt to blindly remedy this I have been trying to "downgrade" to a 3.15 firmware version (through GUI), without success.

The 4.9 kernel builds are not unstable. I'm currently at 10 days uptime on r37015.
That being said, if you're using QoS, you'll likely get better performance from one of the 3.18 builds. Otherwise, the 4.9 builds are fine.
OP's problem sounds like something else.
it strictly depends from its use 4.9 builds could be fine if you use it with basic settings, in my case it didn't lasted even a flash, had to erase nvram manually rebuild and it was
not stable at all currently im on 3.18 and its a rock solid.. http://www.desipro.de/ddwrt/K3-AC-IPQ806X/Test-3.18/ddwrt-netgear-R7800.bin _________________ Atheros

I lost my wifi and internet connection on 4.9 every day and router have to be restarted and Kong complain about similar problem. It newer happened on 3.18, you are lucky if 4.9 is rock solid. _________________ Netgear R7800

I was able to revert to 3.18 but problems with internet drops persisted.
Went back to factory Netgear firmware with no improvement. So, assumed a hardware issue and Amazon replaced with a new r7800.
Initially (about a week) with new r7800 and after updating to current Netgear firmware I had zero issues. Currently, after flashing with 3.18 r37495M kongat, I'm having continued similar issues with wired ethernet internet drops. Wireless has been stable. Occurs on both wired iMac and Roku devices and isn't fixed with reboot of the device(s) but does regain internet with reboot of the router through GUI. Prior to router reoboot, I can't access ddwrt GUI via wired connection but can via wireless....fixed with reboot.
I'm at a loss. Considering reverting back to factory permanently or potentialy trying a "standard" or brainslayer build.
