Might be good to see contents of log files from around the issue. From telnet (or ssh) console:
less /tmp/log/dnscrypt-proxy-2.log (ignore that one since I realized you are not using DNSCrypt)
and
less /tmp/log/messages
and for both files scroll to the time when you have lost your connection.

Signal is fine and I don't have a problem with the internet,speeds or VPN. It's only when I use the add-on my router doesn't like something.
In answer to your original question, the router is connected to my ISPs modem.

Thanks, will try and get a log the next time it drops.
At the moment i have disabled all add-ons and it seems to be holding ok.
Will wait for a couple of hours before i enable an add-on one day at a time.
 
Based on my experience there might be an issue with some corrupted files/errors in the config file that could even survive reset to original settings. You might try reset plus mtd erase netgear command. Obviously you will lose all the config and mods with that step.

I'd like to try this but not sure how.
Are you able to direct/guide me to this "mtd erase"? Also is it safe?
 
From console:
mtd erase netgear
reboot
In addition you can try reset to default values either from GUI or by pressing and holding hardware reset button.
If you will put those commands as written above you should end up with clean config.
Might be good to create backup of the config prior to the reset (but do not apply it after reset, at least not immediately).

I have tried the hardware reset button in the past and from the GUI and noticed once its booted up it will still connect to my VPN lol. So hopefully this command should do the trick. Will try it tomorrow :)

Sorry to hear that. I have R7800 and was sure mtd toolkit is available on R9000 as well. Try searching on the web for R9000 nvram erase.
Also to doublecheck there is indeed no mtd you can run:
find / -name mtd

Hi percy3, and thank you for your help and good suggestions!

While trying to find out farenheit's issue I implemented your wish for WiFi device info.
It will be in next version of the add-on!

Example output:
Code:

What do you think?

@kamoj,

Is there a way to list as well networks identification and in output replace MAC addresses with names? Something like:
###2.4G###
host_a 52Mbps -59dBm
host_b 114Mbps -79dBm
host_c 70Mbps -63dBm

###5G###
host_d 845Mbps -63dBm

###2.4G Guest###
host_e 70Mbps -63dBm
host_f 1Mbps -71dBm

Looks great! The only info I can think of in addition is connection time but I guess that would be available only from DHCP lease and not necessary is going to provide info about last disconnection. So probably of not much use.

I started from scratch with everything.
Reset my isps modem, reset my router and also upgraded it to the latest fw.
Restored my settings and installed the latest add-on. It's been a day now and all is working great. Fingers crossed.
I still have the dnscrypt 2 enabled but not active, should I have this active or should I just disable it?
Thx all for your support
 
@kamoj I am still no sure about it but having quick look at log files it seams after upgrade of your add-on following error is being logged:
kernel: [Warning] skb_warn_bad_offload!!!
Could you check your syslog if you got the same?
 
Yes, I have them too.
This error also exist without add-ons.
I've seen it in since I started using my R7800.
Sometimes there are more of these logs, sometimes less.
Are you getting more of them when running OpenVPN with high load?

I googled it long time ago, and as I remember the error is due o a bug in the kernel, corrected in kernel 4.x...

Enabled means that you have the service installed and ready to use.
Just switch it on, by issuing these commands from the command prompt:
Code: 
nvram set dnscrypt2=1
nvram commit
reboot
