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

802.3af 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.

Where did you end up buying your R750, if you don't mind sharing? If not, no worries. Thanks!

I would rather not say bec I use several competing vendors on different projects and would rather not risk them identifying each other.

I still think you should first confirm channelization to make sure it isn't stuck at 40 MHz, and then survey for MCS/dBm.

Of course, no worries at all.

I'm checking that now! Thank you for the continued comments and help!

I did this, the speedflex was a little better but not tons.

Real world https://www.att.com/support/speedtest/ not much different.

In 2020 / 2021 and spending close to $800 on a commercial Access Point for a residential home I would expect some pretty stellar performance.

Bummer an $80 Chinese router performs the same. Yes, has many options for commercial and major mesh managed networks. Cool, but still.
