Slow Internet Speed Through Switch (SG3452P)
Hello everyone,
The problem I am have is slow internet speed through a new (SG3452P) switch. The setup I have is xfinity internet to a Netgear Nighthawk Modem (Model#CM2050V) to a Qnap Router (Model# QHora-322) to A New TP Link Qmada (SG3452P) Switch. I Get about 1,252Mbps Downlad speed & about 33.82Mbps Upload Speed from xfinity. If I plug my laptop into the Qnap Router I get the same speeds. But when I plug in to the TP Link Qmada (SG3452P) Switch the speed drops down to 522.97Mbps Downlad speed & about 42.05Mbps Upload Speed. I tried difference patch cable (CAT-5 & Cat-6). But I allways get the same results. When I Log into the router the port says the speed going out is 1G and when I Log into the switch it say the port is getting 1G. Any ideas would help. Thanks
Hi @WhoMe08721
Thanks for posting in our business forum.
Do you have any QoS or any speed-related settings on the router?
I see that you have another switch that is throttled as well.
The server is not the same. I am not sure the reason why but it could be a DNS problem. It resolved to a different server.
Like I said, I require an iperf test instead of a speed test like this. It does not reflect anything about the hardware or the switch performance but your actual Internet speed. Iperf at least tells if the switch can perform on all its ports at 1 gig or not.

If you follow the guide of the iperf and do this test on the switch with two PCs, then the switch functions okay.
There is no problem with the switching chipset which concludes that the switch is not the cause of your slow Internet connection.
Like what I suggested previously, it could be a problem with the DNS. You did not mention any of this.
If you have reset the router and the switch, then this rules out the settings on the router/switch and hardware issue now. It should be your computer or the other settings like DNS stuff. Or the diagram or hardware connection.
You can RMA the switch and see if there is any difference but it is confirmed that the hardware of the switch is good. 1Gbps is available on the switch.
