Got the new RBK852/Orbi Wifi 6 system today from BB. Getting it up and running was easy. Started testing speeds and realized that the speed between the satellite and the router is very low. The satellite is about 35 feet away with straight line of sight and nothing in between. First connected a Macbook to the ethernet port of the Router and ran iperf3 to a linux box connected to the same layer 2 network. Speed was ~ 900Mbps as expected. Next connected the same PC to the ethernet port on the satellite and ran iperf to the same server. Speed is average of 195Mbps: Connecting to host 192.168.1.191, port 5201[ 5] local 192.168.1.6 port 57862 connected to 192.168.1.191 port 5201[ ID] Interval Transfer Bitrate Retr Cwnd[ 5] 0.00-1.00 sec 27.0 MBytes 227 Mbits/sec 78 99.0 KBytes[ 5] 1.00-2.00 sec 25.7 MBytes 215 Mbits/sec 9 174 KBytes[ 5] 2.00-3.00 sec 22.6 MBytes 189 Mbits/sec 37 137 KBytes[ 5] 3.00-4.00 sec 21.4 MBytes 179 Mbits/sec 18 113 KBytes[ 5] 4.00-5.00 sec 24.7 MBytes 207 Mbits/sec 25 112 KBytes[ 5] 5.00-6.00 sec 25.0 MBytes 210 Mbits/sec 31 170 KBytes[ 5] 6.00-7.00 sec 24.4 MBytes 205 Mbits/sec 153 60.8 KBytes[ 5] 7.00-8.00 sec 21.9 MBytes 184 Mbits/sec 37 116 KBytes[ 5] 8.00-9.00 sec 18.3 MBytes 153 Mbits/sec 28 133 KBytes[ 5] 9.00-10.00 sec 25.2 MBytes 212 Mbits/sec 42 164 KBytes- - - - - - - - - - - - - - - - - - - - - - - - -[ ID] Interval Transfer Bitrate Retr[ 5] 0.00-10.00 sec 236 MBytes 198 Mbits/sec 458 sender[ 5] 0.00-10.00 sec 235 MBytes 197 Mbits/sec receiver The main reason to buy this unit was to use the advertised backhaul Wifi6 speed. Anything I can do to troubleshoot this ?

I wish it were something of note related to Orbi AX settings, but it was stupid: It was a bad ethernet cable to the machine connected to the Satellite. It was registering properly as gigabit full-duplex, and upstream to the machine was fine, but downstream must have been error correcting. Because it was working otherwise, I unfortunately blamed the Orbi until I could do more testing. Replaced the cable and things sped right back up again. With my laptop wired to the Orbi, I can now get close to Gigabit transfer speeds. Wireless AC (MBP isn't AX yet), I get around 500-600Mbit now across the Orbi backhaul (Router to Satellite) to the server, which isn't bad all things considered... My Orbis are also 2 floors apart through floors with radiant heating, so it's pretty impressive. This is with the 3.1.6 firmware (which was posted live briefly but is now apparently beta?).

I see this as well, internally on the network between Router and Satellite. When connected to the Satellite via WiFi, I can pull a solid 350Mbit/sec externally, so the Backhaul seems fine. But when transferring within my network, I get very slow speeds for some reason between devices connected to my Router and Satellite. Uploading to a Synology box (1000mbit wired to Satellite) from a MacBook Pro (1300 tx to Router), I'm seeing like absurd 50Mbit speeds. Hopefully it's just a firmware problem they can fix...

Ignore my previous post. I was actually able to resolve this and am seeing good speeds now. Can't seem to find a way to delete or edit posts here.

NateIU Don't leave us hanging. What did you do to resolve your speed issue?

How are the speeds with you connect your NAS to the RBR? NateIU wrote:I see this as well, internally on the network between Router and Satellite.

  Marginally better after updating firmware to 3.2.7:
  
  [ ID] Interval Transfer Bitrate Retr
  [ 5] 0.00-10.00 sec 290 MBytes 243 Mbits/sec 425 sender
  [ 5] 0.00-10.00 sec 288 MBytes 242 Mbits/sec receiver
  
  My Note 10 Plus connected to Satelitte is pulling > 350 from the internet. So I would say the wired interface performace is still pretty bad.

    Something I would make contact with NG about.

So what is the backhaul on the Orbi Wifi 6 system?

I know that despite the touted backhaul on RBK53, I seem to get a maximum of around 33 MB/Sec, and am looking to improve this (ethernet on RBR50 and ethernet on RBS50).

I have an iMac 5k in my office (with Thunderbolt 3 attached Drobo 8D) connected to ethernet, and a Synology Diskstation 1817+ in the downstairs family room (egress). I actually had to physically move the Synology upstairs and hook up to a RBS50 ethernet port to do my restore of the 8D due to the slow backhaul.

    Can you tell me what that translates to between an ethernet connected device on the router to an ethernet connected device on the satellite (assuming a good data connection between the router and satellite)?
