    The MT7711 is a modem/router combo device. And going router----router causes a double nat unless setup properly. 

    IT doesn't always cause issues but when it does, then you need to fix the 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.
    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.

Any updates on this? 

Mines working going on over 2 days with a GS-108 switch connected behind the MR.

Here are my hardware:

Cable Modem: MT7711 24X8 Cable Modem

Two unmanaged switches:

  • Trendnet TEG-S80g 
  • Netgear ProSafe GS108

The cable modem has 4 LAN ports. MR60 is connected to one of the ports. All WIFI device connected to MR60 network work well.

 

MR60 firmware version: V1.1.7.132_2.0.64

 

When I connect switches to the cable modem LAN ports, wired connections are good. But when I connect the switch to the Ethernet port of MR60, no wired connection can be established.

 

Is there any step or configuration change I should take? TIA.
