Hello,
I have the following setup :
Fast internet router from my provider -> connected to powerline sender ->sends to tl-wpa4235 receiver which is connected to a 1Gb switch next to my computer.
From this switch i have a connexion to my computer 1Gbs.

Internet is very fast but when i want to transfer files from my NAS (which is connected directly to my router (provider) i only achive transfer rates of 5-6 mb/sec

When i connect my computer directly to my router (provider) i achieve 80-100 mb/sec transfer.

Does anybody know why file transfer is so slow via the homeplug ?

Thanks in advance.
