    RT-AC66U B1 - LAN interface acts strangely

    The connectivity between devices on a powerline network is basically layer 2 (just like an unmanaged switch). I have a suspicion that if I did this: ...that I would run into the same problem - because we are putting both interfaces of the router on the same network segment. Not sure why this...

    RT-AC66U B1 - LAN interface acts strangely

    So you mean this: Now the problem is that the devices on the other end of the other powerline adapters can't access the LAN or the internet.

    RT-AC66U B1 - LAN interface acts strangely

    Here's why what you are saying won't work: As you can see, there's no way for the router to get to the internet this way.

    RT-AC66U B1 - LAN interface acts strangely

    Unfortunately, this didn't work. I changed the MAC address for the WAN adapter on the "WAN - Internet Connection" page to a different MAC address, but this had no effect on the problem. I am thinking the only resolution is to use managed switches instead of unmanaged switches and create a VLAN...

    RT-AC66U B1 - LAN interface acts strangely

    That won't work because then there's no connection back to the DSL modem. (Remember, there are two interfaces on the router.)

    RT-AC66U B1 - LAN interface acts strangely

    The reason for this design is to place the router in a more advantageous spot to maximize its signal. Moving the router to location of the DSL modem greatly attenuates the WiFi signal (particularly the 5GHz band).

    RT-AC66U B1 - LAN interface acts strangely

    That's interesting. Thanks for the info. Before I'm able to test this I'm going to find out if the Qualcomm-based RT-ACRH13 has the same default.

    RT-AC66U B1 - LAN interface acts strangely

    I will give that a try; thanks. What's your idea about what might be happening?

    RT-AC66U B1 - LAN interface acts strangely

    There is only one router (DSL modem is in bridge mode) and one DHCP server (the router). As noted, the network segment shared by the gigabit switches and the powerline network is all layer 2 (unless I am misunderstanding something). The fact that both of the router's interfaces are connected to...

    RT-AC66U B1 - LAN interface acts strangely

    The reason for the powerline adapter configuration is to position the router in a better location in the house. The gigabit switches are not smart switches, so the physical network segment switch -- powerline -- powerline -- switch should just be layer 2, unless I am missing something obvious?

    RT-AC66U B1 - LAN interface acts strangely

    DSL is in "transparent bridge" mode (no NAT). Router performs PPPoE and NAT (wireless router mode). There is a gigabit switch on either side of the powerline adapters. That would be layer 2, I thought. It works with the RT-ACRH13...if it's not valid then i would think it wouldn't work at all...

    RT-AC66U B1 - LAN interface acts strangely

    What specifically is invalid about it, why does it work fine with the RT-ACRH13, and how can I fix it?

    RT-AC66U B1 - LAN interface acts strangely

    Update: If I disconnect the WAN interface from the RT-AC66U B1, then I am once again able to ping the LAN interface. Reconnect WAN, and LAN interface stops responding again.

    ASUS static route not working from 2.4 GHz network

    Update [2020/12/20] This seems to have been resolved in a later version of the firmware. I'm now running version 3.0.0.4.382_52243 and it works fine.

    RT-AC66U B1 - LAN interface acts strangely

    I have an RT-AC66U B1 and have updated the firmware to ASUSWRT 3.0.0.4.386_40558. My network configuration is as follows: (TL-PA7010P are AV1000 powerline adapters) I have an older RT-ACRH13 that works fine in this configuration. When I put the RT-AC66U B1 in this configuration (using the...

    ASUS static route not working from 2.4 GHz network

    Update [2018/04/06] I have narrowed down the scope of the problem. If my PPPoE connection is active, then the static route does NOT work. If I stop the PPPoE connection (e.g., suppose I enter invalid PPPoE credentials), the static route DOES work. I have delivered this information to ASUS...

    ASUS static route not working from 2.4 GHz network

    Configuration I have an ASUS RT-ACRH13 router (latest firmware as I write this: 3.0.0.4.380_8228) and DSL service (CenturyLink, PPPoE). The DSL modem is configured in "transparent bridge" mode (no NAT, PPPoE, etc.); the ASUS device is configured to connect with PPPoE and all of that works fine...
