Gigabit Network Problems

[Greg0986]

Hey all,

I am having some slight issues with my network. This is how it is currently setup; I have my Desktop and HTPC connected to a gigabit switch in the same room. The gigabit switch is then connected via powerline to the router which is connected at 100Mbps.

I can access the internet fine through all the connected devices. However, when I start transferring files between the Desktop and HTPC (Big files 20GB+), I only get transfer speeds of around 2MB/s. I assumed that with a gigabit switch, it should be faster. I then did some troubleshooting starting with removing the powerline connection from the switch. I then transferred the same file and I achieved speeds of over 50MB/s which is great.

Why should the powerline/router be restricting the speed when it is essentially on its own network?

and

What can I do about it apart from removing the powerline/router cable just to transfer some files?

Cheers all

Right guys. Thanks for the recommendations. I have tried copying a file and then disconnecting the powerline connection and the speed increased almost straight away. I don't have any other switch to try.

I changed both computers link speeds to full duplex 1Gbps. It is very strange. It is almost as if the powerline connection is slowing the network down.

I removed the DHCP option from the router and rebooted everything and gave everything its own static address, connected everything up and tried and it is still very slow. If you need to know, the switch is a TP-Link 5 Port Gigabit Desktop Switch (TL-SG1005D).
