Trying to set up a Netgear Orbi with Arrius BGW210-700 (ATT Fiber). Many posts I have been reading suggest placing the Arrius modem in IP Passthrough mode, which I understand is very similar to Bridge Mode or Modem Only Mode. The most recent suggestion on point was from 2017. Can anyone please provide specific instructions on how to place the BGW210-700 into IP Passthrough mode. Any other suggestions for trying to have the BGW210 work with Netgear Orbi. Thanks in advance.
