RBK752 Real World WIFI Speeds

Won't let me put in the crrect model number for some reason. I have the RBK752 system (AX4200). I have a Gigabit connection and am able to get speeds over 900Mbps to my router consistently. When I am hard wiored, this is the speed I usually get. However, my average WIFI speeds are under 500Mbps, sometimes beloiw 300Mbps. I am losing half my speeds over WIFI. This is 5Ghz on a Macbook Pro and iPhone 11 Pro. Shouldn't this Mesh system be able to give me full speeds on a 5Ghz connection? It's rated at 1200Mbps. WHy am I losing so much speed?

Depending on support and design of wifi devices, mimo, antenna configuration, 2x2 or 3x3 or 4x4, you may not see anything near 900Mpbs on wireless. For AC devices, they usually max out at around 400-500. While I was surpised seeing 700 on my MBP 2018.

WiFi 6 put to the test! 802.11ax iPhone 11 any good?

Re: RBK752 Real World WIFI Speeds

So I'm on a newer MacBook Pro on 5Ghz. I'm 3 feet away from the router. And then I also have an iPhone 11 Pro. What speeds should I expect on these devices? I already chatted and talked directly with multiple tech supports and they had me make tweaks to settings. But nothing really improved it. I spent almoist $500 on this mesh WIFI system and it seems pretty slow to me. Losing half my speed compared to wired.

The wifi speed limitation is mostly in your wifi clients.  You purchased an AX system but only very new clients, like iPhone 11 Pro and later, support wifi 6.  These clients can achieve 600 or 700 Mbps over wifi but older clients will get much less (even on 5Ghz).  For best results test your speeds using speedtest.net app or wifi, not the Orbi measurement.  Mac wifi cards have also been reported by some posts as slow.

 

Another thing to check is that your ISP modem is bridged to your Orbi, otherwise your home network is traversing through multiple routers.  If the Your IP shown in https://canyouseeme.org/ is not the Internet Port IP shown by http://orbilogin.com/ Advanced, then your modem is not bridged and you have Double NAT.

Re: RBK752 Real World WIFI Speeds

Ok I checked and my IP addresses match. So my iPhone 11 Pro is still getting very slow speeds compared to hardwired. Here are a few comparing tests I just completed. Comparing wired to wireless connection speed tests over the app one right after another alternating. Som what is the reason I'm losing over 60% of my speed in some cases? Just wondering if there is somethiung wrong with the units I received and if they need to be returned.

 

WIFI

335 Mbps

385 Mbps

344 Mbps

407 Mbps

 

Hardwired

926 Mbps

918 Mbps

857 Mbps

903 Mbps

Re: RBK752 Real World WIFI Speeds

You would need to test the iPhone out on a different wifi system to see if the problem follows or not. Would help rule out the iphone or Orbi. 

 

I know my mac book sees over 700Mpbs on wireless and it's only AC supporting.

Wired is always 900Mpbs or over.

Re: RBK752 Real World WIFI Speeds

It may very likely just be wireless randomness but if you're concerned you can try swapping units.  You need to make sure that your iPhone 11 Pro is communicating over wifi6 to the nearest thing.  Maybe try turning off your satellites and running the speedtest app on your phone standing near the base station.

 

Have you changed any of the default settings and don't enable Circle or any of the other security features?  Besides a fixed wifi channel (pick one that is not the most congested in your area, for 2.4Ghz only choose from 1/6/11) and WPA2 you shouldn't need to change anything else.  You might improve wifi speeds with Short preamble.

 

Wireless has extra overhead than wired like encryption and packeting, but you should still be able to get 600-700 Mbps under the best conditions with your wifi 6 device.

Also use WiFiSweet Spots on your phone to see what the connection rate is between the iphone and the RBR and RBS.
