Orbi 770 - Buffering

The issue comes to when devices, mostly iPhones, will start to buffer video, reels, scrolling.  Device is stationary, not that should matter with the mesh network.  Using videos as an example, it will buffer for 5-10 seconds and then continue.  This was never an issue in the past, only once the 770 were installed.  here is a quick look at the current setup.  This should not be happening, must be a seting somewhere! 

 

Orbi 770 

Router RBE771

  • Firmware: v10.5.20.7 (as of Feb 12 2026)
  • Connected to Xfinity Modem via 2.5gbps port.

Satellite 1 RBE770 

  • Firmware: v10.5.20.7 (as of Feb 12 2026)
  • Wired Backhaul direct from Main Router - Cat 6a

Satellite 2 RBE770

  • Firmware: v10.5.20.7 (as of Feb 12 2026)
  • Wired Backhaul direct from Main Router - Cat 6a

WAN Tab

  • Unchecked: Port Scan  \ DMZ \ Respond to Ping
  • Checked: Disable IGMP \ Disable SIP ALG
  • MTU Size 1500

LAB Tab

  • RIP Direction = Both
  • RIP Version = Disabled
  • Use Router as DHCP Server is checked

IPv6 = Disabled

 

System seems to look connected and speed tests are usually good however the download speed results are never consistent, can range from very low to 1,600.  I have 2 gig services so I expect higher results.

 

The placement of the Router and Satellites are the SAME as my older orbi system. Orbi 770 with 3 units should be more than enough for my house, so the specs say.

 

 

iPhone setting - at least one.

iphone settings have been modified per some of the discussions on this group. 

Low Date Mode off

WiFI 6E Mode off

Private wifi Address = Fixed

Limit IP Address Tracking - Off

 

ipv4 = Automatic

DNS = Automatic DNS Configure

HTTP Proxy = Off

    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

    Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended. 

    What is the connection speed rate seen on the RBRs web page under Advanced Tab/Show Stats for the WAN port?

    How are you speed testing? Ethernet is most accurate for speed testing high speeds at the RBR. 

     

    What is the size of your home? Sq Ft?

    What is the distance between the router 📡 and satellite(s)🛰️? 30 feet or more is recommended in between RBR 📡 and RBS 🛰️ to begin with depending upon building materials when wired or wirelessly connected.

     

    What iOS version is on the phone? I see 26.3 is out in the wild now.

     

    Does this happen with the RBS turned OFF? 

    Does this happen with both wireless and wired devices? 

    What channel configurations are currently set on the router?

     

    Try disabling the following and see:

    Armor, Smart Parental Controls, Protection Engine, Traffic Meter.

     

    Try using some custome IPv4 DNS like cloudfare or quad9.
