Hi @NorthHill 

Thanks for posting in our business forum.

Not sure why you are insisting on getting 2.5Gbps.

As for now, 900Mbps is the normal speed you should get between them. You have all gigabit devices but only a switch that's 2.5Gbps. Getting a gigabit speed is what you can expect from this unless your whole network is based on 2.5Gbps devices.

  @Clive_A As I noted in previous posts, most of the network has 2.5gb NICs or better. Five of the six servers have 10Gb intel NICs or SFP+ with 10Gb. The 2 primary PCs that are directly connected to the SG3210 have 2.5gb Intel NICs installed. The EAP660HD likely will never hit 2.5Gb, but should be getting better than 700-800MB for the devices connected to it with capable WiFi and within reasonable range. I am not that ignorant to assume I'm going to get 2.5gb speeds with only gigabit devices.

 

Prior to posting here, I underwent most reasonable attempts a sysadmin would do for a new device - including extensive searching on the web and the TP-link website. I came here looking for help, not condescending criticism.

 

Why would I spend the money on 2.5Gb hardware for my business if I didn't have a need and/or didn't want to at least get close to achieving speeds within acceptable ranges. The 940-960mbs is great for gigabit devices, but I didn't pay for that.

Not being condescending but I am confused by what you craved all the time. Since ER7206 and other switch SG2008P are gigabit devices. I mean you've done a series of tests based on them and they are involved in part of your topology. They are limiting this to 1Gbps eventually as long as you pass over them. This is not gonna be fixed unless everything. Everything means every device from the router to the switch and clients are all based on at least 2.5Gbps if you expect a 2.5Gbps speed at least. You cannot tolerate a gigabit device in the switching if you need 2.5Gb.

Replacing the router would not help if you are testing a speed to/from SG2008 in the future. 2008 should be replaced with an M2 model as well.

I am only pointing out this as you are stuck in the obsession with getting more than 1Gbps speed while your network is not ready for it.

If you mean this speed problem now only resides in the SG3210XHP-M2 with two 2.5Gbps or above NICs/modules installed, and it cannot even pass 1000Mbps, that's a different story. We don't have to get other stuff involved and just troubleshoot over the switch. The diagram is not important as well as the sole purpose of this switch, the switching function has failed to operate normally.

And I think we are not on the same page, at least with a diagram and marking out the devices failing to get the theoretical speed.
