Hello all.

I've been browsing the forums for a couple of days now and have seen some similar issues brought up, but no matter what suggestion I try I can't seem to get my wireless speeds up to where they should be.

I just got a new HP Pavilion laptop with wireless N capability.  I've owned the DIR-655 for about a year and love it, but was not using its wireless features until I got this laptop (I have my PC and PS3 hard-wired into it and get great speeds).

Anyway, when I try a speed test from my laptop online like at dslreports.com, my results are consistently at 3 Mbps down and about 2 Mbps up.  They do fluctuate a little lower than that, but I have yet to see them above that number. Watching streaming video on the web is nearly impossible on my laptop, as the video has to buffer every 10 seconds.

On my PC (connected via ethernet cable) I get test results consistently at or above my ISP's advertised speed of 16 Mbps down and 2 Mbps up.  

In addition, when trying to copy a large file like a video from my PC to my wireless laptop, the transfer speed doesn't go above 3 Mbps.  Depending on what settings I enable/disable on the router (like forcing 40 MHz channel width in the router settings or changing the wireless channel or transmission rate) it actually goes down to about half that speed.

Basically, I've tried every setting I can think of on the router and can't seem to get anywhere.  I'm about to pull my hair out, so if someone could help me out it will be greatly appreciated.  All suggestions are welcome.  

Thanks in advance.

EDIT: I forgot to mention that distance from the router is not an issue, as I am having these problems with the laptop even when I am 12 feet away from it with a clear line of sight.

Verify your wireless adapter on you rlaptop is set to "Auto" for N communication.
It was set to 20MHz, by default, for my laptop.

Check your connection speed. Verify idle should be around 150Mps. Actively downloading, normally, should be 200 or higher.

I'm also assuming you went through the 300 Mps sticky.

Thanks for the reply.

Mine was as well, I already changed that setting from 20 MHz to Auto 20/40 MHz.  It may have been your post that I read regarding this.  Unfortunately it hasn't improved my speeds.

Can you explain this further please?  I looked through the router settings and didn't see anything that looked to be related to this.

I did, and since making that change the adapter does show a speed of 300 Mbps.  Unfortunately my actual network speed hasn't changed.

Look at this for tut to get N-speed

Thanks, I did all that, short of using the D-Link wireless utility.  The adapter does show a speed of 300 Mbps, but it hasn't improved my actual speed.

You can't count with 300 Mps that only teoretical. What speed did you get ?
16MB = 128megabit  2MB = 16megabit

I've made a couple of changes to the router settings, namely disabling Short GI and Extra Wireless Protection, and speeds have increased somewhat.  Here are the latest speed test results.  This is from my PC connected to the router via ethernet cable:



Here is from my laptop:



Based on the speed from my PC, the wireless N speeds should be higher than this right?  At the very least I should be able to transfer files across my own network at a speed much higher than 6 Mbps.

I go to Network and Sharing Center in Vista, then view Wireless Connection Status.
Mine will say 150 Mps when idle, faster when actively downloading.

It's usually says 300 Mbps on my laptop, and does go down sometimes, but I can still only transfer files between my networked PC's at a speed of about 5 or 6 Mbps.

This is really annoying me.

[Macks1974]

Anyone else with suggestions?  What kind of data transfer speeds do other people get across their network via wireless N?

I believe you gave yourself the needed clue.  DO NOT LOAD OR USE THE D-LINK utility.  It will pound your performance and connection reliablility.  Use the MS "ZERO" utility only.

I think that will solve your problem.  If it doesn't you can always go back to how you had it.

Actually, I haven't used the D-Link utility at all, I was saying that I did everything on that post except for downloading that utility.  I'm just using the built-in wireless utility in Windows 7.

Hi Macks1974,

What Anti-Virus program are you using? You need to download the program to your computer and run the program from your computer and not use SpeedTest.net, because that measures the Speed from the computer to a Site on the Internet not on your Local Network.

I'm using Norton Internet Security.

And I realize that the SpeedTest.net results were Internet speeds, I posted that because the Internet speed I am getting from my wireless N laptop is nearly identical to the data transfer rates I am seeing over my local network (5 to 6 Mb/s, tested by copying a large file over the network and watching the data transfer speed).  My understanding is that both of those speeds should be quite a bit higher.

Tried a Trial Copy of Speed Meter Pro and it may help you figure things out.

It is not Network Magic.
