Background:
Currently I have the following devices on my home network:
- Router Asus RT-N16 (Latest Firmware Version:3.0.0.4.376_3754)
- HP MicroServer Proliant Gen 8 (Windows Server 2012 Essentials)
- Desktop PC (Windows 10 with wireless stick tp-link wdn3200)
The problem:
While the internet speed seems to be good (download on MicroServer is 11MB/s and on the desktop is ~3MB/s), the speed for accessing the MicroServer from desktop PC (wireless) starts from 500kB/s and rapidly drops to 0.
If I try to access the server while on lan, the transfer speed is ~4MB/s, which also seem slow.
If I try to access the server with my tablet I will have 300-700kB/s.
I already tried without any luck:
- disable TCP checksum Offload as described here: http://www.sevenforums.com/network-sharing/2503-extremely-slow-file-transfers-network-access-4.html
- follow the steps from here: http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/very-slow-200kbsec-file-copy-between-win7-machines/b8736b1b-0a91-4567-ba33-215084ffc906?auth=1
- disabled the Domain member: Digitally encrypt or sign secure channel data (always) and Microsoft network server: Digitally sign communications (always) as described here: http://jrs-s.net/2013/04/15/windows-server-2012-slow-networksmbcifs-problem/
Thank you!
Edit: I reinstalled windows 10 on my desktop, installed dd-wrt on router and I made a few tests with Lan Speed Test:
