New Gigabit internet

Hey everyone. I just had spectrum gigabit internet installed today. The brought a new modem and a separate router. When the tech was there he had me test the internet speed and I was getting close to ...

If you measured 500 Mbps with Orbi over WiFi, then everything is working up to specs and there's nothing more for you to do.

 

Orbi is a 2x2 WiFi device with a maximum link rate of 866 Mbps.  Throughput is typically 50% to 65% of the link rate, due to the overhead inherent in the WiFi protocol, so 500 Mbps is typical for a link rate of 866 Mbps.

 

Orbi is intended to provide good speeds over a large area, not to provide maximum speed for a single device right next the to AP.

 

If you think you need more than 500 Mbps throughput over WiFi then you need to buy another WiFi solution.

Thanks for a detailed reply. Is there anyway to know the current/realtime link rate between router and satellites?

    The wireless backhaul link throughput is 1.7Gbps in the AC3000 Orbi's (RBR50/RBS50 which has 4x4 backhaul antennas), and is 867Mbps in AC2200 Orbi's (RBR20/RBR40/RBS20/RBS40/RBW30 which has 2x2 backhaul antennas)

    Not that I know of.  Perhaps there is via telnet and the command line, but there's no documentation.  It's not realtime but probably the best way to assess the backhaul connection is to run an iperf3 test between wired devices, one on the sat and one on the Orbi router.  The most I've measured is about 575 Mbps, but that's with a couple walls between. 

     

    Several folks are giving incorrect info on this thread.  The iPhone XS is one of the latest models.  I believe it's a 4x4 WiFi device and the OP said he measured 900 Mbps throughput on the iPhone XS.

      Nope ... 4x4 only on the LTE side, 2x2 for 802.11ac -> https://www.apple.com/lae/iphone-xs/specs/

       

      All models
      • Gigabit-class LTE with 4x4 MIMO and LAA
      • 802.11ac Wi‑Fi with 2x2 MIMO

        Thanks.  If the XS is only 2x2 on WiFi, then only one of two things are possible:

        1. The iPhone XS supports 160 Mhz channel widths (1733 Mbps link rate). OR

        2. The OP did not actually measure 900 Mbps over WiFI with his phone.
