I'm running an R7000 on DD-WRT v3.0-r35965M kongac since he released the firmware. I've had no issues at all up until maybe the past couple of months.

My internet and/or wifi will drop randomly and at any interval. Sometimes I'll reboot and it'll lose either again within minutes, sometimes it'll last for days.

I've tried an nvram erase and redid my settings (very basic, only 2 people ever connect to it, I don't use IPV6 or any other features) multiple times to no avail.

I'm considering trying to flash the firmware to the latest BS build here but, considering it used to run indefinitely without issues before, I'm worried maybe it's failing hardware.

I recently got my gf bluetooth earphones and thought maybe that might interfere so I tried playing with Bluetooth Coexistance (and learned why that setting exists) but it didn't help the issue.

I've read some people had issues with DDNS and QoS enabled so I've just disabled DDNS (i use noip sometimes) but left QoS on to try and figure out what's causing this issue -- if it isn't hardware related.

Does anyone have any tips on trying to figure out what might be happening?

The wifi drops more than the internet does.

If the wifi drops and I try to change any setting in ddwrt and "Apply Settings" , the router seems to fully crash and I need to hard reset to get it back (which led me to believe it's more of a software issue thaan hardware but couldn't rule it out).

Any help is appreciated.

Sure sounds like flakey hardware. 3 years is about the most you can use these home grade routers and reasonably expect the hardware to hold up. Anyway, you pretty much diagnosed it yourself. The firmware / config did not change from when it was working properly. The old stack of 120 or 130 fucked up radios I used to have will attest to the fact that hardware does fail and typically with intermittent operation.

Same thing for me.

Since some versions, WIFI is not stable.

For now, I rolled back to Firmware: DD-WRT v3.0-r42366 std (02/14/20)

I have tested :

03-29-2020-r42813 => Wifi unstable
03-05-2020-r42617 => Wifi unstable


Netgear R7000 :

#1 - DD-WRT v3.0-r42366 std (02/14/20) - running since 03/30/20 - DHCP Off / VAP Off & Wifi 2.4 / 5Ghz
#2 - DD-WRT v3.0-r37015M kongac 09/23/18 - running since 09/23/18 - DHCP On / VAP On & Wifi 2.4 / 5Ghz & Isolated Guest Network
