Really slow lan transfer performance
« on: September 13, 2008, 03:37:36 PM »

Transferring files between my desktop machine and laptop is horribly slow.

The desktop is using DWA-552 adapter, and connecting at 300mbps. The laptop is connected at 130mbps.

Transferring files at a rate of 2.21Mb/second. Where my older WRT54G router used to transfer files at roughly 5Mb/second.

DIR-655 rev A3, 1.20 firmware.

Both systems using Windows Vista Ultimate, but the desktop is the 64bit flavor.

^BUMP^

Surely someone must know why performance is so slow.

Would going back to firmware 1.11 help?

Hi Edtek,

What is the Transmission Rate set at? Take it off Auto and try the different rates.

I have a similar problem too.
My comp conntects to the router with a cat5 cable, and the other comp connect with a dwa-547. It says 300mbps. But when i try copying files, it's about 1900kb/s. It's friggin' slow :\

I 've already downloaded the newest drivers for the computers.

I tested my computer with the otherone wired, and i set my network adatper's parameters: (these settings were the bests. the speed of copying was about ~10.5mb/s with an old UTP cable and a new CAT5 cable)
VLAN: Disabled
Flow Control: Enabled
Jumbo Frame: 4KB MTU
Speed: Automatic Speed & Duplex

After this, i disabled the wired lan on the other computer, and enabled the DWA-547.
It was still about 0.8mb/s.
I disabled WISH, QoS, WPS, and set the Wireless Encription to none the 801.22 mode to g and n, and the speed was ~10.5-11.14 mb/s. (It's still really slow for a 300mbps connection.)

After, i turned on WPA /AES encription. The speed dropped to 2.3-3.0 ~mb/s.

Hi Prince,

Your Product: http://www.dlink.com/products/?sec=1&pid=530 D-Link DIR-655 Router works with your adapters, but is not a matching adapter for the D-Link Router of yours.

Your Adapter that you are using isn't going to give you as high a speed as a matching Adapter will for the Router.

The best I have been able to get out of this router was 11.6Mbps, and that was between two 300Mbit connected computers.

I had so many issues with this router, and spent so much time with tech support on the phone I finally gave up and smashed it. Literally.

Currently I went back to my older WRT54GL router and I get pretty much the same speeds as the DIR-655 and the range is pretty much the same; I am not losing anything by the "switch".

If anyone would like to glue it back together, I can send it to them :)

Now I am trying to figure out a frisbee method for my DWA-552 wireless card. I figure it should fly 30-50 feet without to many problems, but I would like it to have some sort of boomerang effect before smashing into the ground.

thecreator,
Thanks for the info, good to know it's a problem too..:)
This config wasnt cheap either, so does it worth to replace? What is your best speed between two computers?

Thanks in advance:)

BUMP. On my wired network CAT6 gigabit/4k JUMBO / WINXP I used to get 25mb/s. After I upgraded to Visat Ultimate 32Bit It dropped to 6MB/s. If you have kaspersky anti virus it slows down your connection becuase it scans the files while transfering. You'll know if this is happening if the transfer goes to like 3 or 4mb/s.

Test File:
a) 3.5G image file
b) 4.5G 8 DIR varoius RAR sizes


DIR-655 Settings:
EVERYTHING YOU CAN IMAGINE! I disabled and enabled everything.
Static IP's

LAN:
1) Gigabit PC (Enabled / Disabled Jumo Frames)
2) DNS-323 (Enabled / Disabled Jumo Frames)
3) CAT 6 cabling brand new

When copying files from NAS to PC I wonder if the DNS-33 user authentication could slow it down. If so how to reverse this. BESIDES a drop of 20MB/s is ridiculous. When I used XP prior to the upgrade to Vista there was a jump in performace from 18MB/S to 25 MB/S when I enabled Jumbo frames.

Any help here would be great.

I tried to reproduce this and found that I was getting 2.4-2.9 MB/s from a wired XP box to a wireless laptop, which is around 24 Mbps (8 bits per byte plus a little overhead).  I live in an apartment with a lot of other Wi-Fi and 2.4 GHz cordless stuff around me, so I wasn't expecting much more than that.

I'm wondering if everyone else is mixing up 2 MB/s for 2 Mbps -- the difference is that 2 MB/s is 16 Mbps -- which is what you might expect if you are transferring between two different wireless clients (two wireless hops).
