Just got my AX4200 mesh to replace my buggy Google mesh system. Very impressive!!! All the connections are stable and lighting fast!! However, just a naive question. Why my backhaul only works at 1200Mbps instead of 2400, which is the one stated in the spec?Any thoughts?? Thanks in advance!!

>> The 2400Gbps is a misprint, unless anyone can show otherwise. I say this with confidence as we have installed over 2 dozen RBK73 systems. Not one of them does 2400Mbps backhaul. This is the problem. Their marketing and tech specs says the backhaul (specifically the backhaul, not a combination of devices) is 2400Mbps. For those with devices, the only customer facing information says 1200Mbps. If that 1200Mbps backhaul rate is true, then this is false advertising and enters lawsuit territory. Now, that said, I am starting to side with those saying this is a UI display issue. I finally telneted into the router and get this information (sensitive information <redacted>): ath11 IEEE 802.11axg ESSID:"<backhaul wifi>" Mode:Master Frequency:2.447 GHz Access Point: <redacted> Bit Rate:286.8 Mb/s Tx-Power:29 dBm RTS thr=64 B Fragment thr:off Encryption key:<redacted> Security mode:restricted Power Management:off Link Quality=0/94 Signal level=-98 dBm Noise level=-98 dBm Rx invalid nwid:59 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 gre0 no wireless extensions. eth1.4093 no wireless extensions. eth2.4093 no wireless extensions. sit0 no wireless extensions. ath02 IEEE 802.11axa ESSID:"<looks like a backend admin wifi>" Mode:Master Frequency:5.24 GHz Access Point: <redacted> Bit Rate:1.201 Gb/s Tx-Power:28 dBm RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=0/94 Signal level=-98 dBm Noise level=-98 dBm Rx invalid nwid:76615 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 lo no wireless extensions. eth3 no wireless extensions. eth3.4093 no wireless extensions. ipsecdummy no wireless extensions. ath01 IEEE 802.11axa ESSID:"<guest wifi>" Mode:Master Frequency:5.24 GHz Access Point: Not-Associated Bit Rate:0 kb/s Tx-Power:28 dBm RTS thr=64 B Fragment thr:off Encryption key:off Power Management:off Link Quality=0/94 Signal level=-98 dBm Noise level=-98 dBm Rx invalid nwid:3 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 ifb1 no wireless extensions. ath2.4093 no wireless extensions. eth2 no wireless extensions. br-guest no wireless extensions. ath2 IEEE 802.11axa ESSID:"<backhaul wifi>" Mode:Master Frequency:5.785 GHz Access Point: <redacted> Bit Rate:2.4019 Gb/s Tx-Power:29 dBm RTS thr=64 B Fragment thr:off Encryption key:<redacted> Security mode:restricted Power Management:off Link Quality=0/94 Signal level=-101 dBm Noise level=-101 dBm Rx invalid nwid:27534 Rx invalid crypt:12 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 ip6tnl0 no wireless extensions. teql0 no wireless extensions. ifb0 no wireless extensions. soc0 no wireless extensions. bond0 no wireless extensions. ip6gre0 no wireless extensions. miireg no wireless extensions. eth1 no wireless extensions. wifi2 no wireless extensions. ath1 IEEE 802.11axg ESSID:"<personal wifi>" Mode:Master Frequency:2.447 GHz Access Point: <redacted> Bit Rate:286.8 Mb/s Tx-Power:29 dBm RTS thr=64 B Fragment thr:off Encryption key:<redacted> Security mode:restricted Power Management:off Link Quality=0/94 Signal level=-98 dBm Noise level=-98 dBm Rx invalid nwid:127032 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 ath13 IEEE 802.11axg ESSID:"<looks like a backend admin channel>" Mode:Master Frequency:2.447 GHz Access Point: <redacted> Bit Rate:286.8 Mb/s Tx-Power:29 dBm RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=0/94 Signal level=-98 dBm Noise level=-98 dBm Rx invalid nwid:133630 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 ath11.4094 no wireless extensions. wifi1 no wireless extensions. ath2.4094 no wireless extensions. br-lan no wireless extensions. ath11.4093 no wireless extensions. ath12 IEEE 802.11axg ESSID:"<guest wifi>" Mode:Master Frequency:2.447 GHz Access Point: Not-Associated Bit Rate:0 kb/s Tx-Power:29 dBm RTS thr=64 B Fragment thr:off Encryption key:off Power Management:off Link Quality=0/94 Signal level=-98 dBm Noise level=-98 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 gretap0 no wireless extensions. eth0 no wireless extensions. wifi0 no wireless extensions. ath0 IEEE 802.11axa ESSID:"<personal wifi>" Mode:Master Frequency:5.24 GHz Access Point: <redacted> Bit Rate:1.201 Gb/s Tx-Power:28 dBm RTS thr=64 B Fragment thr:off Encryption key:<redacted> Security mode:restricted Power Management:off Link Quality=0/94 Signal level=-98 dBm Noise level=-98 dBm Rx invalid nwid:67888 Rx invalid crypt:7 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0

Max is 1147 for 2.4 and 2402 for 5g I believe

Possible his system is using 2.4Ghz wireless backhaul...

The 7 series is:2.4Ghz - 600Mbps5Ghz - 1200Mbps5ghz Backhaul - 2400Mbps So, the 7 series is reporting everything right except for the backhaul speeds (showing 1201M).

So this is my interpretation:The AX4200 is a combined throughput when you have 1 router 600Mbps 1200Mbps, 1 Satellite 1200Mbps, 1 Satellite 1200Mbps. The 2400Mbps backhaul is derived from the 2 combined satellites connecting to the router giving 1200Mbps+1200Mbps connection.With all due respect to whoever told you that, that is completely and utterly false.System speed has never been based around the number of satellites, the system itself is tri-band and the "speed" is adding the band speeds together.2.4 GHz Fronthaul - 600Mbps5 GHz Fronthaul - 1200Mbps5 GHz Backhaul - 2400MbpsThat's why you'll see every single Orbi RBK75X System labeled as AX4200, same with RBK85X being AX6000 with variants of each ranging between 2-4 satellites.There's only a couple possibilities here, either it is a bug (firmware or Router GUI) or the system's specs are incorrect.

AX4200 (rbs750) backhaul only works at 1200Mbps

  What Firmware version is currently loaded?
  What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
  Is the Orbi system operating in Router or AP mode?
  
  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 wirelessly connected. <This will impact actual connecttion speeds seen between the RBR and RBS.

    Thanks for moving my post to the correct forum. It is hard to test the actual backhaul speed. I knew it is running under 1200Mbps from the "Show Statistics" in the "Advanced Home" on web GUI (see the attached screenshot in my original post). Both the router and two satellites are updated to the latest firmware (V3.2.16.6). That mesh system is placed in a ~ 1700sqft two floor unit. And it was on Verizon FiOS 300/300. Since the AX4200 delivered the stable and fast WiFi coverage, I am not complaining the "slow" backhaul. In fact, I am just curious about how the backhaul works. Will the backhaul only be boosted (to 2400Mpbs) under havey load?
