What's the best setup to get fast internal network speeds?

[sygyzy]

I just moved from a house with a 3Mb Verizon DSL connection to one with a 12Mb cable connection. The difference is in the first place, I had all computers/devices hardwired into a Gigabit network. Only laptops and phones were wireless.

In the new place, everything is wireless. I am obviously stoked at the 4x faster Internet download speeds but I am really disappointed at the internal transfer speeds. The reason why I care is I have a NAS that I move files to on a daily basis. I am on a 802.11N network and am getting really lame speeds, like 500KB/s. That's like 12 minutes to move a 350MB file. It's equivalent to a 4megabit connection.

Assuming I cannot wire the house and I cannot change the position of the computers, what is the best setup I could get to improve local transfer speeds. For example, would getting a dual simultaneous router and a 5ghz wireless card for my PC help?

Those speeds you getting are low even for wireless.
Maybe changing the channel might help. Also might try to change the wi-fi standard from N to different one (I know N is the fastest but just for diagnostic purposes )
Also if nothing helps I'd try using different protocols for sharing the data, what kind of file transfer are you testing the speed?
SMB (windows share)? FTP? NFS? or HTTP? try more ways if it's possible, some protocols have more some have less overhead.
Also if there is no packet loss in your transfer you could try some UDP based transfers like TFTP.
Not sure if any of this helps.

Try those 500mbps powerline adapters. I have the Trendnet 500 and they are working great. Old house with old circuits and still managed to get 10MB/s thru put, basically like a fast ethernet connection.

Before switching out hardware, I would download/install a wireless channel utility, check to see if there are other wireless networks near the channels you are using, then move your network away from them. You can get improved performance that way. What type of security are you using? I would use WPA2 + AES if possible as it provides better performance than TKIP supposedly.

There are at least 6 other wireless devices online now at my house and just got

and it briefly went over 50 (charter turboboost)

I'm on the 15/3 tier.

You have some interference or other problems.
