Hi,

Firstly, I would like to introduce my devices in home environment.

1. Router - DIR-657 FW: 1.01
2. Storage - DNS-325 FW: 1.02 (2x HDD WD Green 1TB, RAID 0)
3. Laptops with Wireless N

I configured my home network that router and storage working on cable with manually 1Gb/s speed connection. Unfortunately when I connect my laptops via Ethernet cable to router I have almost 12 Mb/s (via Wireless N is almost 6 Mb/s).

What is going on? What I should do?

Apologies for my poor English grammar.

Many thanks for help,
Kamil

Are these numbers your posting UP for down?

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.

Some things to try:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.

What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N?
300Mbps Connection Requirements! Please Read!
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES only. Some WiFi adapters don't support AES, so you might want to try TPIK only. However TPIK isn't supported on N mode only.
Might change from Auto Scan to Manual Channel on the WiFi.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off Short GI and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing.

Check cable between Modem and Router, swap out to be sure. Cat6 is recommended.

Be aware that Connection speeds differ from actual file xfer speed and we'll never see the file xfer speeds match the same. If your connecting at max speeds, your average file xfer speeds on what your seeing is about right on the WiFi. Wired should be faster however this is due to the routers traffic management and any features and filters you might have turned on that can effect wired performance.

One thing I recommend when using routers and doing lots of file xfers between devices on the LAN side, get a external Gb network switch. This helps eliminate router management and processing interference while doing xfers between devices on the LAN side of things. Most routers with the ports in back have some sort of management processing going on on the ports thus there is some degradation on speed as it's having to process the data thats coming in and out of it. Having a external switch eliminates this.

I see usually about 50-60Mb on the upload to my server from a wired PC and about 9-12Mb on the up from my Mac Laptop to the server via 5Ghz single mode N. 2.4Ghz is about 5-8Mb I think. It's been a while since I've used 2.4Ghz.

I have the same problem.

I have DNS-325 with 2x 2TB WD Green in RAID1.
Router is DIR-615.
Laptop is Toshiba A300-233.

I get same speeds as you do.

Generally, when I change everything what you say the transfer from DNS to laptop via Ehternet cable was raise to 130Mbps.

But the Wireless mode is still in 5Mbps

Why do you keep your Wi-Fi in mixed g/n mode? As long as a single g-client is connected, all n-clients will be downgraded to g-speed as well. Unless, of course, your access point is having a dual-band radio.

[FurryNutz]

What happens to the speed if you use Single mode N?

I believe that this is about the speeds you should be seeing when using WiFi.

If your needing to xfer lots of files or large size files and you do this a lot, I recommend getting a Gb swtich and implementing that as your mode to xfer files. It will save you time.

12Mb/s equals pretty much to maximum one can get from 100mbit ethernet.
wireless on the other hand is ****e for interference, I usually get average of some 3Mb/s with my 802.11n, but sometimes 6-7Mb/s, my wlan AP is about 5 meters from the laptop.

So this is to say that you are getting the max out of 100mbit ethernet and good result with the wireless.
