My Galaxy S4 have the newest firmware from Samsung I9505XXUGNF1 (Kitkat 4.4.2). My router is a Asus RT-AC66U to which the S4 connects with max speed of 433 Mbps. My internet connection is 120 Mbps.

When I do a speedtest on the S4 I get results of ~110 Mbps, but when I'm downloading a file over LAN from the disk connected directly to the router I get download speed only of ~20Mbps (2.4 MB/s) which is very sucky!

My Laptop have only a N network card, and connects to the router with max 300 Mbps and when I download the same file I get over 7.5 MB/s!! (~65 Mbps).
Speedtest also shows results of over 110 Mbps...

I remember when the phone was new, and it had Android 4.3 (~10 months ago), I had LAN download speeds of over 9-10 MB/s...

I tried with different file managers like X-Plore and others, but it looks like it is not the app problem.

does somebody know what could be the problem?

Same problem on Galaxy Tab S (SM-T805)
The same is happening to my Brand new Galaxy Tab S.

It is connecting to the WiFi with 866Mbps, and files inside the network are download only at ~3 MB/s


does anybody have the same issue?
