Model: EAP670  
Hardware Version: V1
Firmware Version: 1.0.9 Build 20230512 Rel. 66757(5553)

Newbie: this is my first EAP670, my first real access point. I want to implement network segmentation for my LAN using VLANs.


Router: Two ASUS XT8's (WiFi 6) in mesh with wired backhaul. 2.4GHz 2x2, 5GHz-1 2x2, 5GHz-2 4x4.

 

The EAP670 speed numbers make me think I don't have the settings correct. I used iPerf to measure the stats:
iPerf on EAP670 and the client is in the same room:
2.4 GHz   -tx 151 Mbps  -bandwidth 126 Mbps
5GHz   -tx 376 Mbps  -bandwidth 315 Mbps

 

iPerf on EAP670 and the client is on a different floor and 100 ft from the AP:
2.4 GHz  -tx 4.12 Mbps  -bandwidth 3.44 Mbps
5GHz   -tx 44 Mbps  -bandwidth 36.9 Mbps

 

My problem is that the XT8 mesh numbers are significantly better:
XT8 System Log with client in the same room:
2.4GHz  -tx 72.2 Mbps  -rx 72.2 Mbps
5GHz   -tx 1201 Mbps  -rx 1201 Mbps

 

XT8 System Log and the client is on a different floor and 100 ft from the AP
2.4GHz   -tx 72.2 Mbps  -rx 72.2 Mbps
5GHz   -tx 866.7 Mbps  -rx 866.7 Mbps

 

The EAP670 is stock regarding the settings. I am considering three EAP670's for a mesh network with VLANs but the speeds have me re-thinking these AP's. I'm a newbie and my first thought goes to operator error. Am I making any mistakes here or not understanding the data correctly?


Thanks for helping,

Greg

Welcome to the world of Enterprise APs versus Home Wireless Routers...

 

4804Mbps is the total max the AP can handle... you have to consider enterprise APs are built for large client count and stability during heavy load.  They are programmed differently than home wireless gear.  Put 500 clients on the Asus and it will PUKE... the 670 is built for that load.

 

It's almost like buying a corvette and a MACK truck.  Vette is fast... but the MACK is fairly fast without a loaded trailer.  NOT as fast as the Vette, but it will pick up and go... well introduce the 16 wheel trailer... Vette cant do it, but back up the MACK to it and go.  That's really the comparison.  

 

You are comparing apples to oranges when it comes to 2 different applications... 

 

At the same time, are you really going to saturate 500mbps+ every second of the day?  Probably not.  I push 10TB a month out of my home, but ride around 30-50mbps during the week and 100mbps during the weekends (with my kids friends over).

Hi, is your network layout ASUS XT8)))((((ASUS XT8----EAP670?

How far is between ASUS XT8 and the EAP670?

Tried using a 1m-short cable connecting the EAP to your network for testing. Change the channel, channel width, Tx power to optimize the wireless environment.

Just striving to develop myself while helping others.

First off - just be looking at your TX, those are low numbers.  Need to change it to a cleaner channel.  The cleaner the channel, the higher those numbers will go.  Higher the TX/RX is you will get more real time wireless speeds.  

 

Have you expanded the 5ghz to 160, and tested it?  Crank the power up to high?  

 

I wouldn't worry about the 2.4 speeds, you won't get anything blazing fast off of it.  

 

What's the signal strength between the Asus mesh?  You have to make sure you have enough signal between the Omada APs to utilize the full strength of the wireless backhaul.  Easiest way to do that is download Acrylic Home Wireless on your laptop and look for your SSID and look at the signal strength.  Anything lower than -70 is a good signal.  More in the -60 below is where you want to be.  

 

Also - you have to remember, every hop, it will cut the wireless backhaul bandwidth down.

Thank you for the help. Following is the LAN topology:
Firewalla switch -- Asus XT8 Mesh AP -- Asus XT8 Mesh Node (1 floor down, about 100 feet away) - ethernet backhaul @ 1.0Gbps
                |
                 -- TP-Link EAP670 (in same room with XT8 Mesh AP)
                 
My wireless client is an HP 3570 with an Intel Wi-Fi 6E AX211 160MHz running at 1.2Gbps


I have been running the tests with both the EAP670 and XT8 powered on in the same room.

EAP670 - I made the following changes, all else is stock:
5GHz    Channel Width 160MHz, Channel 40/5200MHz
    After reboot, Status Radio Settings Max TX Rate 4803.9Mbps
2.4GHz    Channel Width 40MHz, Channel 1/2412 MHz (no one on it)    
    After reboot, Max TX Rate still 573.5Mbps
Changed Security from WPA/WPA2 to WPA2/WPA3 on both channels. Enabled OFDMA.
Power on both bands is set at max.
            
iPerf on EAP670, Client in same room with AP on and XT8 on            
                Transfer (Mbps)    Bandwidth (Mbps)    
EAP670    2.4GHz    168.00            140.00    
EAP670    5GHz    550.00            461.00    

From Asus System Wireless Log:
XT8        2.4Ghz    43.30            72.2    
XT8        5GHz    780.00            866.7    

 

FAST.com        All values Mbps    
iPerf on EAP670, Client in same room with AP on and XT8 on            
    Internet Speed    Download    Upload
2.4GHz    207            167            153
5GHz    577            520            227
XT8        547            663            350

With EAP670 Off            
XT8        547            430            277
    
I expected the 5GHz throughput would be much higher, especially since I'm in the same room as the WiFi APs. If the APs can provide up to 5GHz 4804Mbps why do I only see 1/4 of it? The area around this installation has a lot of other 2.4GHz and 5GHz traffic, although signal strength on MetaGeek's inSSIDer is much higher for the local LAN.

Are these numbers to be expected or am I missing a setting which could open up the pipes?


Thank you very much for the help. I truly appreciate it.

Greg

  @KimcheeGUN 

Thank you for the reply and the straight talk.

It's the Mack truck effect I am after: VLANs so I can separate out IoT devices, a more robust guest network, L2+ management, and the ability to handle the ever-increasing number of connections.

 

Your point about the maximum throughput of the AP vs one individual connection's requirements was something I had not considered. I won't have clients requiring 5Gbps throughput but I do need their connections to be stable. I've noticed problems on the consumer gear when the device count gets high and the XT8 begins to drop connections. I am anticipating the more robust EAP's will take such matters in stride.

 

Multiple VPN connections to other offices have us averaging 70-115 GB per weekday. Pushing that through a 4800 GB per second pipe should be a walk in the park for the Mack truck.

 

I believe I see the light. Thank you for your help and your illustrations. 

 

Greg

  @KimcheeGUN assuming you are correct... then why even have AX3000 or faster AP's with 160Mhz channel width support?!

I'm not assuming.  It's the truth.  I worked for a networking vendor, and that's how the developers looked at enterprise wireless.  It's internal speeds.  Not "internet" or "wan" speeds.  Not looking at "gaming" speeds.  

 

It's internal wireless speeds.  Client to client under 1 AP speeds.  Client to server under 1 network.  You have 200-300 people in an office crunching away on their laptops.  You need speed and stability at the same time.  You can't have more speed and less stability, it all has to equal out to keep production going.  That's how the Enterprise AP world works.  

 

There isn't a switch that turns off "enterprise" mode and goes into "residential" mode.  That is burned in / developed into the device.   

 

I'm not saying that you CAN'T get your speeds that you want.  It will take a little more effort, knowledge, and testing to get it there.  Because you are playing in a different ball field now.  That goes by different rules than residential wireless.
