R750 Slow Speeds

One of my homes has Cable Internet speeds rated at 450 Mbps Down & 20Mbps Up.


I have a Arris TM1602 DoCSIS 3.0 16x4 > Ubiquiti EdgeRouter 12


At this location I had a...


27" iMac (Model Spring 2019)

iMac > Cat 6 Wire > EdgeRouter 12 = 450 Mbps Down & 20 Mbps Up

iMac > WiFi 5 > PhiComm K3C AC 1900 = 380 Mbps Down & 20 Mbps Up

iPhone 11 Pro (2x2 WiFi 6 Chipset) > WiFi 5 > PhiComm K3C AC 1900 = 365 Mbps Down & 20 Mbps Up


I picked up a Ruckus R750 Unleashed and added it to the EdgeRouter 12


27" iMac (Model Spring 2019)

iMac > Cat 6 Wire > EdgeRouter 12 = 450 Mbps Down & 20 Mbps Up

iMac > WiFi 5 > Ruckus R750 = 375 Mbps Down & 20 Mbps Up

iPhone 11 Pro (2x2 WiFi 6 Chipset) > WiFi 6 > Ruckus R750 = 362 Mbps Down & 20 Mbps Up

Note: I am powering the R750 with a POE+ Injector but could it may be under powered?

I know if it is under powered it may not perform as well as it should but I find it hard to believe an $750 Access Point can't beat a 2 year old $80 consumer router, especially since R750 is WiFi 6 Certified and I'm using an iPhone 11 Pro with WiFi 6 2x2 Chipset.


PoE Injector = Cudy 30W Gigabit PoE+ Injector Adapter, IEEE 802.3 at and IEEE 802.3 af Compliant, up to 100 Meters (328 Feet), 10/100/1000Mbps RJ-45, POE150


Ruckus Power Specs

https://www.commscope.com/globalassets/digizuite/61778-ds-ruckus-r750.pdf (Page 5)

802.3af PoE = PoE: 12.54W

802.3at PoE+ = Full Functionality = PoE+ : 22.34W    /    DC Power: 22.69W

Ruckus Optional Accessories 

These are much higher power specs than stated above in their power specs.

902-0180-XX00 · PoE Injector (60W)

902-1170-XX00 · Power Supply (48V, 0.75A, 36W)


Super appreciate any advice even if it's not related to the R750 just seems odd to me. Thank you!

I will also run iPerf3 tests between server (iMac) and iPhone to test the speed of the hardware minus the ISP. This will rule out any ISP issues. I still think hitting the same 450 Mpbs as a Cat 6 cable via the iPhone 11 Pro via the 2x2 WiFi 6 chipset should be easy.

I suggest confirming your channelization and see what your dBm and MCS are like from various locations.
This is 7 ft from my R750 AP:
AP Rx Signal (dB) 40
AP Tx Data Rate 11/80/2 / 1.20G bps
And Ookla shows the following (1G down/35M up svc):

What does your speedflex say? This would be a more hardware to hardware comparison. 

I’m less concerned about the connection out to an ISP provider as that has many more speculative conditions. 

thanks! 

I don't want to run speedflex as it doesn't work well with my VLAN set up.

I am hesitant to run speedflex as I never got that working.  Maybe it's due to my VLANs... never bothered to ifgure it out.

But regardless, whatever it says, it won't be less than actual measured external bitrates....

Yep all good, not curious about lower but if it’s higher speeds hardware to hardware. 

Thanks!
