R750 Slow Speeds

[roger_federer]

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

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

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

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 turned off the 2.4 radio, still the same sub par performance.

It could be that the R750 is running on a different channel and/ or channel width from the router, due to interference and/ or settings, limiting the current performance. Testing them with the same settings should create a more level "playing field"

Tbh this doesn’t make a lot of sense to me. When you say router you must mean the Access Point. The router is an Edgerouter 12 and doesn’t have channel width. 

[john_olsthoorn]

OK, that was not completely clear: I meant the PhiComm K3C AC 1900 wireless router, compared to the R750 access point.

[roger_federer]

Ah gotcha. I’ll do that and see what happens! 

Thanks!
