Post by: changing on September 25, 2008, 05:17:42 AM
Hi all, I am new here.

May I knw why i am getting 52mpbs, sometime during game is 104mbps. but it does not hit 300mbps as stated on the router manual? i use all N equipment, so it is not hardware fault. But I am not sure how to achieve the 300mbps. can any kind soul pls teach me? or is there is thread open for it?
currently my firmware is 1.20, using wpa settings.
Thanks for taking time help me

Could you please list the brands and devices you use?

Are you using Cat6 or Cat5? Did you make it yourself or buy it?

i using TP link TL-WN821N adapter but Dlink router.

more info of this adapter: http://www.tp-link.com/products/product_des.asp?id=140

what do you mean by cat 5 or 6? is it from router to modem or pc, If it is the question, i am wireless not wired connection.

using window configuration. Last nite, i on alot online application, max it hit was 161 mbps then drop down. very unstable, even though i have flashed to 1.21 , how do i static the 300Mbps, pls advise.
thanks

You probably won't be able to see 300 with that adapter.  In order for an adapter to hit the 300 speed it needs to be able to operate on the 40 MHZ channel width to hit 300 with this router.  They don't list what chipset is in this adapter but it most likely only operates on the 20 MHz channel.

TP link uses Atheros chipsets.
Title: Re: DIR 655 WAN MBps

atheros chipset meaning?
so there is no way i going to get 300Mbps with this adapter?
thanks forthe reply.

The Atheros chipset is what is used in the DLink products, so you should be able to connect to the router at higher connection speeds.  You may have to check into the advanced porperties of your adapter in the Device Manager to see if some of these may need to be tweaked to get the higher speeds.

IcIc, so how do i set the settings in the device manager? what might be the consquences that may result from wrong settings to its default settings? I very scared if i am going to make spoilt it, even though it is under warranty. please kindly advise me
thanks

You won't void any warranties changing settings in the device manager.  Open the device manager find you nic, right click it and select properties, there should be an advanced tab where you can change its settings.  Depending on your adapter there may or may not be a lot of choices here.  If you are unsure of your changes , write down what all the original ones are first.  If there is a manual for this adapter it may tell of what settings can be changed and what each one does.  Also Google can be your friend for finding explanations of what each setting does.

Devices from the same manufacturer are usually (more or less) guaranteed to work well together. Eventhough the same chipset brand is used, there can be differences in feature implementation and versioning by the vendor, causing issues that can affect connection speed.

There is nothing you can destroy with the settingss in NIC properties.

is there a way to make it more stable.
while gaming in counterstrike souce, it lags on and off very time.
quite distribing compared with my dgl-4300 wireless G
is there a thread to stablize the transfer and recieve speed.
i notice i am sending out alotof bytes, even though i am not surffing the web or on any online application.
thanks

Wireless signals are constantly transmitting and receiving whether or not you are browsing.  Even when your computer is on, because that's how it maintains a connection.

As far as making it more stable, you'd need to reduce interference between the devices.

reducing interference between the devices as in?
Title: Re: DIR 655 WAN MBps
Post by: Reinvented on September 27, 2008, 03:12:18 PM
Interference can be distance, and walls, or anything else in between.  It can also be from other wireless devices such as phones, etc.

A lot more phones are using 5.8 GHz wireless, so you may have problems there as well. 

If you are having trouble with signal strength as well, I recommend you use something to reflect the signal if need be, to get around corners, or to hit each of the corners in the home or wherever. 

But, a good bet is that your 52 Mbps can't be sustained either because of distance from the router, or interference from other devices, or both!

If you have to go through multiple walls, plus have cordless phones, you'll surely have some issues.  You'll have to slowly remove each of those problems to see what really causes it to go down.

If worse comes to worse, and IF you don't have any other clients, you *could try* to lock the transmission rate at the maximum speed, and see if it'll help.

I do not recommend this however as it can be detrimental as far as performance goes.  You may receive signal degradation or lost packets and have lots of retransmits.  May even cause lag.  So, it's not necessarily a good idea, but also worth a try.

Connecting at a lower speed often brings more stability then chasing the highest connection rate. Why connect at 300 Mbit internally while you only have an 8 Mbit DSL line that connects you to the online game?

speed on wireless is dynamic
btw how fast do you copy using TeraCopy?
if over 5 mb/s then its on high speed 11n
regardless of reported connection speed

btw my DIR-655 WebInterface Wireless section says its connected at 130mbps but on my vista SP1 32-bit HTPC with a DWA-140 it says 300mbps

i not sure how to connect my NAS to it. so i dun knw the copy speed.
I am still lagging in the game, how do i set the QoS for counterstrike? is there a thread for it?
I wonder is its MIMO working cos, it is works, i am not suppose to lags.

thanks

Lag can be caused by external causes too...

Hi changing,

It might help, if you log into your Router's settings and change the transmission rate to MCS 11-52[108] Mbit/s. Also try changing the Wireless Channel and pick one to give you a steady connection. Also do not use Vista's Wireless Network Manager, because I believe its top speed is 54 mbps, not 108 or higher.
