I have AT&T Gigabit, and if I connect directly to the modem, I get 900mbps down/up. However, if I connect through Orbi (wired), the upstream remains the same, but the downstream cuts in half. It hovers around 500 mbps at the most. I have no clue why this is happening. I tried IP passthrough, AP or Router Mode. Disabled all packet filters and advanced firewall rules in Modem. But nothing helps. Is this an issue with Orbi?

at&t router -> orbi rbr 50

Modem Combo Units:Couple of options,1. Configure the modem for transparent bridge mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. tosehee wrote: at&t router -> orbi rbr 50

There is no bridge mode for this modem. I've already enabled the IP Passhrough with fixed DHCP to the Orbi Router. As I wrote in the original thread, that didn't help one bit. I tried both AP and Router mode, and with and without the DHCP Servers in either modem or Orbi router. Neither of them helped at all which is why I am posting the question whether the issue is the Orbi router itself. Again, if I connect directly to the modem, I get 950mbps. If I connect to the Orbi ethernet port, I get 500mbps... At this point, I am blaming the Orbi here.. But I wanted to double check before I return this unit back to Best buy.

Below is the testing result direclty from modem. 10/13/2018 14:38:31 downstream 964.505 70 9.435 10/13/2018 14:38:25 upstream 899.986 70 6.671 And as I wrote, the upstream remains the same, but downstream is only 500mbps WITH hard wired to the Orbi Router.
