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 confirmed that I am connected at 2.5G the throughput of my connections are lower than when connecting on the 1G ports at 1G speed.
QoS is set as port priority. I tested with all the different priorities and ensured no rate limiting on any port.

Test 1
Wifi ax devices <---->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 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.

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

I get a sustained throughput of 110 Mbps to the NAS

Because I am using different 2 brand new and different brands AP and both of them experiencing the same behavior when connecting at 2.5Gbps it seems there is a bug built-in rate limiting for ingress speed on the GS110EMX switch.
Any one having the same problem? Any advice other than trying to call Netgear Support?

The latest firmware, attached is the screen capture. Same problem.
Also, I connected an ASUS router's 2.5 Gbps port, and same problem with upload being throttled or rate limited.
The same problem across 2 x GS110EMX , and 1 x GS110MX. Monitoring on the switch and router shows 2.5 Gbps solid connection over 5ft of e Cat6 cables.
I already tried multiple cables, shielded and no shielded (The same 5ft cables work and support 10 Gbps with no problem).
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.

- 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.
I have the EXACT same issue. 2.5g and 10g ports give extremely slow upload speeds to an ASUS AXE11000. 1g ports are fine. Link aggregated ports are fine.
This problem has been maddening.After long hours, actually days, and multiple tests and HW I found the solution: I replaced all my switches where I had devices connected at different speeds including the GS110EMX
I have successfully tested the following communication patterns:
2.5Gbps <---> 1Gbps
2.5Gbps <---> 10 Gbps
1.0 Gbps <---> 10 Gbps
In my personal conclusion, the problem sits with the switches and how switches handle the flow control and buffer the packets between devices connected a different speeds.
I will send you a direct/private message with the switch that solved all my problems. YMMV
