Slow file transfer on win 7 network

post #1 of 5
Thread Starter 
I have a small home network with 3 computers all running Windows 7. My main computer which holds all my videos is wired into the router and the rest are all wifi. All wireless devices including the router are 802.11n and all of them get 20-30Mbps download and 15-20Mbps upload speeds on the internet. The main wired computer gets around 80Mbps down and 30Mbps up on the internet.

Copying files across my network is horrible. The fastest it will go is 2MBps for 1 very large file and 3-4MBps for several small files. What could be causing such a poor transfer rate? I have listed the things I have already tried to do to fix this below.

I have tried:
Switching wifi channels
Disabling QoS
Moving the router
Disabling Homegroup and using workgroup
Disabling 128bit encryption
Setting all wifi devices to 802.11g and also 802.11n
Router firmware up-to-date
All drivers up-to-date

I should also note that my main system is a Rampage III Extreme with i7 980x and 12gb ram.
I've also tried copying from an ssd on the main system to a ssd on another system with the same results. My system doesn't support jumbo frames so I can't try that.

Do both wireless machines involved in the transfer get 100mbps+ link to the network? If one dips down to 30mbps (which is common), then you will be looking at around 4MB/s transfer speed.

I don't typically transfer between wireless machines, most of my transfers are from my wired machine. The wireless link speed is 64Mbp and I can never seem to get a 100mbps link.

The transfer rate somewhat aligns with your speed test results (keep in mind 8 bits in a byte).

How populated is your area with wifi?

it's pretty populated on all channels and I have it set to the least populated channel. I tried the 5Ghz range also but that didn't help.
