R750 Slow Speeds

New Contributor III

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

802.3af 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.

The performance you had experienced above does not reflect the real performance we are getting from R750.  The client is Dell laptop with 11ax Intel AX200 2x2 card running Windows 10.  Single client it gets tcp downlink 829Mbps, uplink 938Mbps and even higher for udp with 1020Mbps downlink and 1002Mbps uplink.  Suggest you to contact support team to troubleshoot for you.

I purchased this from Amazon (Global Direct Sellers) and it appeared to be new and sealed as far as I can tell.

I just called support...

They would not help me because I bought this from Amazon and said this is likely gray market device. I mean...

He never asked for a serial number or a way to validate if it was an authentic product in my hand.

I find this disgraceful not to know and or support your product.

It's fine if it has no warranty, that's one thing. But if it's a valid genuine product why the hell would they just want to get off the phone and not even check.

This company is sad. Too much, just a little heated about this. 

It would be nice to know if I got a gray market product and help me make sure I buy the correct product. That seems reasonable.

Not sure if you have seen the below message when you ordered from Amazon.  You need SmartZone, ZoneDirector or Ruckus Cloud controllers in order to get the required support service.  If you want to run Unleashed, the part number is 9U1-R750-US00.

Clearly I don’t get the details of all of this.


However, I was able to update this AP to the Unleashed firmware. Doing this successfully doesn’t matter? It means this AP won’t work properly?

And because it’s not 9U1 model, that negates all my questions?

I’m trying to follow the logic of sub text on an Amazon site and how this company explains gray market items to me.

Your explanation and Ruckus Support don’t match. 

Am I missing something here?

So I’ll go buy an authorized R750 9U1.

What happens when I see the exact same issues for speed? Call tech support and now we can talk because I gave someone more money, basically?

Brutal, mired in partnership commissions.
