I have a Win 7 Pro Laptop (quad core) 1GB LAN
A linksys WRT1900AC with a Red Nas 3TB hdd.
My speed was 10Mb/s for wireless or wired file transfer to the NAS.
I did all of the following testing the wireless with no success, at the end I tried the ethernet and I got 63MB/s NOW!!!!!!
So I don't know what setting or registry entry fixed the problem. Wireless file sharing is still slow.
SETTINGS
-Disable Remote Differential Compression
-Disable TCP Auto Tuning
-Disable Receive Side Scaling
On the REGISTRY:
Network Throttling Index:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
NetworkThrottlingIndex=ffffffff (DWORD, default: 10, recommended: 10 for media sharing, ffffffff for gaming and max throughput, valid range: 1 through 70 decimal or ffffffff to completely disable throttling)
Disable Bandwidth Throttling:
Create (DWORD value)
HKLMsystemCurrentControlSetServiceslanmanworkstationparametersDisableBandwidthThrottling
Set Value to 1
Network Memory Allocation (Event ID 2017 error):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
LargeSystemCache=1 (DWORD, default value: 0, recommended value: 1)
A value of zero establishes a cache of ~8 MB, a value of 1 allows the cache to expand up to the amount of physical memory minus 4 MB, as necessary.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
Size=3 (DWORD, default value: 1, recommended value: 3)
1 - minimizes used memory
2 - balance used memory
3 - optimal setting for file sharing and network applications
Need more information: Are you connecting via Wifi? If you're connecting via cables, are they Cat 5? Cat 5e? Cat 6? Cat 7? – Jonathan – 2015-09-02T18:09:25.867
