R6700 constantly losing internet connection
Hi all, I've recently reverted back to the stock firmware from DD-WRT due to some issues with the upping DHCP over 150 clients causing the DD-WRT firmware to crash. I'm trying to give stock a go again, I really like the mobile app, but I'm constantly losing my internet connection.
First it was related to false positive DoS attacks from my work VPN, Facebook or other IPs related to web tools/services. I checked this by reviewing the logs and putting the IP of the attack item from log into the browser and it taking me to various related web assets. I've since disabled DoS protection.
Last night it crashed out of nowhere, just "initialized firmware" in the log. Additionally, it did the same thing today when I logged into the web interface. It seems to keep happening.
Firmware is V1.0.2.16_10.0.57
- Is this firmware really that unstable?
- Are there more detailed logs I can get to find out what's causing it to crash?
- Should I try to re-install the stock firmware?
- Or just go back to DD-WRT, which had it's quirks but was at least stable?
- Throw it all out and use the R6700 as a doorstop?
This is my last ditch effort, I have purchased a Linksys Velop system recently purchased/still in the box as a back up if this keeps happening, this is unacceptable and not condusive for remote work/video calls.

Have you got it back on to stock firmware? It isn't clear from your message.
Not knowing anything substantial about your network, beyond the fact that it crashes, it is hard to begin to guess what might be happening.

Netgear's firmware is great at creating false reports of DoS attacks. Many of them are no such thing.

If these events are slowing down your router, that may be because it is using up processor time as it writes the events to your logs. Anything that uses processor power – event logging, QoS management, traffic metering – may cause slowdowns. Disable logging of DoS attacks and see if that reduces the problem. This does not prevent the router from protecting you from the outside world.

Your call. Originally launched in 2014, this was never the most powerful of routers.

It looks like my screenshot of the most recent log/connection lose didn't post because well, I lost connection while authoring. Anyway, here it is:
- I reapplied the firmware yesterday and it's still doing it. It initializes the firmware and loses connection for one second, then reconnects. Total trash

- I did get it back to stock. I'm going to move to the Linksys Velop mesh I bought as a back up. I didn't realize it's almost 7 years old. I bought it 3 years ago. Now with kids using multiple devices our usage has changed and I need something more powerful.
