2.5gbps uplink on EAP670 speed not as expected
2.5gbps uplink on EAP670 speed not as expected
I have two EAP670 currently connecting to my TL-SG3210XHP-M2 using the 2.5 poe+ port. These two EAP works find on both 2.4ghz and 5ghz band and can give 600-800 gbps on my phone if I'm in the same room which is good. However, I'm expecting multiple device connecting to EAP670 can utilize its 2.5gbps uplink port that connect to my 2.5gbps switch.
I experimented with 2 mobile devices that connected to EAP670 and run iperf3 client that connect to two different servers that also are on TL-SG3210XHP-M2. If I run 1 mobile device I get 600-800mbps and if I run 2 mobile devices I get a total of 600-800mbps. I made sure the 2.5gbps port on my TL-SG3210XHP-M2 is fine by testing on my PC so I'm wondering if EAP670 is just not capable to utilize its 2.5gbps port due to hardware limitation or maybe there's some setting I need to enable. Thanks.

I can’t really tell whether it is possible or not to fully utilize the 2.5G link on EAP670 for a simple reason that I do not own EAP670 myself. My previous messages were about the testing itself. They were not to say that you could reach 2.5 Gb/s on that uplink.
I do not care much about Wi-Fi being supper fast, but prompted by you posting and having some free time, I did some testing similar to yours on one of my EAP660 HD. The testing was done in a similar environment as yours and the results I got were also very similar to yours. In my testing, I reached 100% utilization of the 5GHz channel, but the utilization was jumping up and down all the time. It was dropping from 100% almost to the bottom fast and jumping all the way fast to the top again. At the same time, the controller was reporting a massive number of retries and the rate of them was also jumping up and down. I guess those retries were affecting the utilization. I also ran some longer tests, like 5 min and more, and reached the point that I was no longer able to reach 100% utilization. I guess either the AP or the sever became overheated and switched to the lower processing speed. That’s really all I can say about it. I have developed rather low expectations as to Wi-Fi in general long time ago so I just leave it like that.

@chi844 With the EAP670, I've managed to reach up to 800mb/s. This is due to the 5GHz frequency's limitation with an 80MHz channel width. However, with a device that supports 160MHz, you can expect speeds up to 1.5gb/s
