Hi,

I have been desperately trying to figure out why my lan transfer is soooo slow. If anyone can help I would appreciate it.

I have a D-Link DIR655 802.11n with two computers. Each computer has a D-Link DWA552 802.11n PCI network card.

I get a great connection 300Mbps to the router with each computer. My ping time to the router is <1ms.

Problem is when I go to transfer a file from one computer to another. I am getting transfer rate of 1.5 Meg/sec instead of the theoretical 30 Meg/sec.

This doesn't make any sense !

If someone can offer a suggestion it would be appreciated.

thanks,

slevytam

You probably have leeches using your bandwidth since you have no security enabled.

If you have a cordless phone that is using the same broadcast frequency as your WLAN that can cause interference. Or if a neighbor has a WLAN set to the same channel as yours that may cause problems as well.

Hi,

No leeches since I can monitor who is connected to my router. Also there is no interference. Computers are next to each other and I have selected the optimal channel so that connection is close to 100% from the computers to the router.

Any other ideas ? This must be configuration problem with either windows or the router !

Thanks for the reply

I just got off the phone with D-Link. Product Specialist had the same problem!!! Looks like D-Link has a defective product.

It has been reported to the D-Link Research and Development team for examination. Hopefully can be fixed with a driver update. . .

Hi,

Well i went out and spent 150 each on two wireless cards. Linksys ones. Tried to do an ad-hoc network in windows safe mode (network support).

Same problem. Even worse actually... I got speeds of 300-600 KB/s.

Can someone help me ?

Well in the mean time since your speeds suck even for wireless g I would switch over to those. Just set up your router to only broadcast in g mode. Granted this bites and I would through a fit and return it but if you can't you can whether the storm in g mode until they fix it.

On a side note 30 mbps seems low for what you draft n guys are spending. My super g mimo set up does that with a $25 normal super g card and will do 40 if I spend the $70 for a supger g mimo card. Granted my stuff is prolly no longer supported but at least it works.
