Netduma R2 not connecting to internet (modem)

[Bcobz]

Just got off the phone with spectrum and they restarted everything and I plugged directly into the modem and was able to get internet. 
 

however wifi isn’t working and they said to contact the manufacturer of my router. Last time this happened I had to update the firmware but I’m up to-date (R2 3.0.394) 

im able to access  DumaOS when in incognito mode but connection tests are not even running

If you go to System Information -> Network Status, do you have a WAN IP?

Could you quickly try replacing the cable connecting the R2 to the modem, just to rule that out?

This happened to my R2 this morning as well. 3.0.394 firmware.  I rebooted the modem and router.  The router received the IP from my modem, was able to see network activity, and could do a speed test, but none of my devices could get internet.  I unplugged it twice and that didn't fix it.  I rebooted it from the GUI and the internet started to work again.  Weird that a hard reboot didn't fix it.

. Sorry idk why my profile wasn’t showing your reply notification. I have a WAN interface and it shows an IP.  It does Say “Disconnected” under the network status.

Ok so what i just did fixed the issue. I unplugged everything every cable. I replugged the Duma and let it sit for a minute or two. I then plugged the modem back in and powered it on. 

BEFORE I tried, putting my old router between the modem and Duma and was able to get a wifi signal but couldn't load anything using the internet. I tried turning off IPv6 on WAN and LAN. I reset the router through DumaOS about 8 times. I rebooted both modem and router like 10 times. 

Not sure why i need to do all that but it worked. 

Let me know if there is something i can do to avoid this in the future, Thanks,

OK, I'm not sure either why it would've required all of that to get a connection but it certainly seems like a one-off. Well done.
