HELP GS110EMX low Upload Speed when connecting at 2.5Gbps on ports 9 and 10

Hi All, I hope someone can help and point me in the right direction even though I think this is a software/hardware bug (I hope I am wrong). First - every time I connect on port 9 or 10 and c...

I have 2 new RAX200 both of them show the same behavior - Is the RAX200 throttling the upload speed throughput?

5Ghz Wifi ---> LAN Multi-Gig port connected at 2.5 Gbps the throughput is around 400-500 Mbps for upload, download I get 900 Mbps which is the limit of my NAS connectivity

5Ghz Wifi ---> LAN Multi-Gig port connected at 1.0 Gbps the upload throughput is around 900 Mbps for upload, download I get 900 Mbps which is the limit of my NAS connectivity

5Ghz Wifi ---> LAN 1 Gig Port connected at 1.0 Gbps the upload throughput is around 900 Mbps for upload, download I get 900 Mbps which is the limit of my NAS connectivity

I replaced the netgear switches with other non-netgear and the problem remains. At this point everything points to the RAX200.

Below is my post in the GS110EMX board which I basically closed today and my focus is the RAX200.

NEW HELP GS110EMX low Upload Speed when connecting... - NETGEAR Communities

Test 1

Wifi ax devices <---->RAX200 APs (ax) 2.5G port <----> 2.5G port 9 GS110EMX 10G port 10<----> 10G port 10 GS110EMX LAG 2 x 1G ports <--> NAS

Connection verified at 2.5Gbps between RAX200 APs and GS110EMX

2 different brand new out-of-the-box APs, They are different brands since I am testing them.

My Wifi ax devices are 8-10 ft connected at -33 dBm solid signal in the 5Ghz band using 160Mhz at wifi radio speed of 2.4Gbps solid and stable during all the time of my test. Using inSSIDer to monitor any WIFI interference and there is none.

The sustained throughput I get here with multiple connections from different laptops, different brands, and different OS is around 500 Mbps aggregated across all devices to the NAS.

============================================================================================================

Test 2

Then if I switch to 1 Gbps port on the RAX200 APs to 1 G bps port 5 on the GS110EMX

connection verified at 1Gbps

Wifi ax devices <---->RAX200 APs (ax) 1G port <----> 1G port 4 GS110EMX 10G port 10<----> 10G port 10 GS110EMX LAG 2 x 1G ports <--> NAS

I get a sustained throughput of ~880 Mbps to the NAS

============================================================================================================

Test 3

Then if I switch to 1 Gbps port on the RAX200 APs to port 9 on the GS110EMX

Connection verified at 1 Gbps between APs and GS110EMX

Wifi ax devices <---->RAX200 APs (ax) 1G port <----> 1G port 4 GS110EMX 10G port 10<----> 10G port 10 GS110EMX LAG 2 x 1G ports <--> NAS

I get a sustained throughput of ~800 Mbps to the NAS

As you experience the same with the RAX200 as well as we th the probably very similar Asus consumer router in AP mode, the idea is near that we're facing yet another well hidden performance issue operating such devices in AP mode, well possibly caused by some chip and platform maker implementation issue. Not the first we're reading about on various manufacturers communities. >99.9% of the implementation, testing and marketing money does flow into shiny consumer and influencer channels. Nobody really cares much about AP modes, especially if paired with exotic multi-gig technology. My advise: Stick with true SMB class access points like the WAX6xx series, stay far away from consumer routers for these purposes.

  I think that's what I will do. I am trying to escalate to L3 and I am being asked to run tests on router mode when I have shared that I am not interested on router mode after I provided the backup file of the config. it seems I am being asked to do the heavy lifting.
  
  I will start looking for a SMB AP. Hopefully I have a better experience.

    Hi All RAX200 owners,
    
    Are you able to achieve upload speeds higher than 700 Mbps using the 5 Ghz band?
    
    if you are, can you please post the fw version and hw version if any?
    
    I have not been able to pass 500-600 Mbps when using the 2.5 Gbps port. If I use the 1.0 Gbps then no problem at all. It seems the 2.5 Gbps port is throttling the upload speed with or without QoS.
    
    I was able to push it to ~620 Mbps by configuring the QoS to 1000/1000 Mbps but Netgear does not support anything higher than 1000 even if you are using the 2.5 Gbps.
    
    For some of you interested in my config/ test setup:
    
    I replaced the GS110EMX with a different multigig switch and same problem. No interference problem based on inSSIDer information. 2 different laptops, different brands and different WiFi Card same problem. Tested from iphone and same problem. Using 5ghz band. I am running the latest firmware and tested 2 previous fws same results.
    
    Test 1
    
    Laptop <--- 3 ft from RAX200 signal level -27dbm Tx/Rx wireless 2402 Mbps /2402 Mbps --->RAX200 Port 2.5 Gbps <--->GS110EMX <--> NAS/Local Speed Server Upload speed limited to ~500 Mbps / Download Speed ~900 Mbps
