r2 Internet drops out after a few days

[MarcNHone]

Hi,

Received my R2 router the just under a fortnight ago (Monday).  Setup Virgin Media Cable modem as Modem only and connected to Router. 

I have a separate mesh network so the wireless is turned off and the main mesh device is plugged into an RJ45 port.

After a few days after the internet started to drop out and return irratically, within short periods of time.  I rebooted Cable modem, router, and Netgear GS108PE switch attached, after a few minutes the system was back with no issues.

I initially put it down to my playing with settings etc and thought it wouldn't reoccur.

Today the internet started doing the same thing again and I rebooted all again to recover.  I think it did it the other day too, can't recall which day but I think I waited to reboot later in the evening.

I believe it may be the router firmware, but as I was using the cable modem as the router before this has also changed use (although I have used a router before in this way and don't recall having the same issue).

Is there anything I can do when the issue occurs to verify if the issue is with the router or elsewhere?

Best Regards

Marc

 

p.s. running latest firmware since received.

Further to above:

Looks like it might be the cable modem:  found advice online to get this from it:

(anything I can change on the router to combat this or is it probably reboot cable modem only issue?)

Hey, welcome to the forum!

I have Virgin as well and I find the modem mode to be a little flaky, I'd recommend you switch that back to router mode. You can then put the WAN IP from the R2 System Information page into the DMZ on the V hub and that will resolve double NAT. Try that and see if it is any better. That's how I have my own setup.
