RBK353 drops internet every 20-40 minutes

Morning,

Yesterday I’ve got this set delivered to me as my prev. Network was getting a little outdated. Followed the out of the box installation and works great.

However, for some odd reason, the router somehow loses connection to the internet for a second every 20-40 minutes according to the logs and don’t really notice it until I ‘m gaming.

I’ve tried rebooting, a fresh start up, up/downgrading the firmware and checking my modem’s setting(Bridge), so I’m getting a little lost

    Technicolor router set from Bridge to Router mode and setting up the DMZ, I’ve had zero disconnects and solved my problem

    Much appreciated for the support!!

    Is it causing an issue? Or are you just noticing it in the logs and curious about it? 

    Some isp's set differing times for IP address renewals/lease times.

      Hi Plemans,

      Sure is, while gaming it disconnects you from the game, strangely my prev. setup didnt have these issues at all..

      I was thinking of changing my modem’s setting to function as a router instead of a bridge and setting my Orbi system up as an AP, you reckon this could resolve it?

        what modem/gateway is it? 

        If its a combo device as you're statement implies, it can cause a double nat. 

        A double nat happens when you cascade more than 1 router.

        Fixes? There’s 3 options but only use 1.
        1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions. I've see some ISP supplied modem/router combo devices be pretty sketchy and have poor passthrough mode. 
        2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
        3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.
