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.

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.

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.
-
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.

Thanks. I followed your advice and installed Cisco Speed Meter Pro on both my wired PC and my wireless laptop. Here are the results:
PC
Network Status: No issues found
Internet Speed:
--Internet download speed: Normal (1.37 MB/sec)
--Internet upload speed: Normal (205 KB/sec)
Local Network Speed:
--Speed to Laptop-PC: Normal (6.39 MB/sec)
Laptop
Network Status: No issues found
Internet Speed:
--Internet download speed: Slow (249 KB/sec)
--Internet upload speed: Normal (222 KB/sec)
Local Network Speed:
--Speed to Desktop-PC: Normal (3.78 MB/sec)
I ran both tests multiple times and the speeds varied slightly test to test, but generally they were all pretty close to what I posted above. Again, there were no issues found with the software, but what catches my eye is (a) an internet download speed on my laptop of 249 KB/sec with a wireless N connection at 100% signal strength, and (b) the speed from my laptop to my desktop is consistently 40-50% lower than the speed in the other direction.
The internet speed tests seem a little slow overall, but I'm not too concerned with that since my PC's internet connection through the DIR-655 is lightning quick.
Reactions? Any suggestions?

FYI-
I have tested this router (A4, 1.33NA) on my 35/35 FIOS connection against a Linksys wrt610nv2.
Wirelessly, under the same conditions (i.e., wireless settings), the DLINK only pulls down 30/25 (numerous tests). Linksys pulls down 35/30.

I'm just trying to tell you that this router is not very good wirelessly.
Did you try changing to 20 MHz if you had 40 MHz (OK I see you tried this, but maybe you can try with other channels)? How about changing channels - to say 1, 6, or 11?
You may also want to disable any afterburner or frameburst on both the router and adapter.

Sorry, I didn't mean to sound ungrateful for the reply, I'm just getting really frustrated with this.
You still got something close to your advertised ISP speed though; with wireless N on my laptop I'm getting a fifth of what I get through my wired PC. I'm not asking for lightning quick, just something close would suffice. And I'm getting the same slow speed whether I'm downloading from the internet or copying a file over my own network.
Did you try changing to 20 MHz if you had 40 MHz (OK I see you tried this, but maybe you can try with other channels)? How about changing channels - to say 1, 6, or 11?
Yes, I've tried 20 MHz only, 40 MHz only, and auto; I have yet to see any better transmission speeds than what I posted above. I've also tried every different channel and left it on auto-select with no result. I've even tried giving up on wireless N and reverting back to G, but that's even slower.
You may also want to disable any afterburner or frameburst on both the router and adapter.
I'm not exactly sure what either of those things are but I don't believe I am using either one; at least I can't find any references to them.
EDIT: I did find an Afterburner option on my wireless network adapter's settings but it is disabled.

Hi Macks1974,
You are talking Laptop and Desktop Computers along with the DIR-655 Router.
What Adapters are installed on each and what are they rated for?
Below are links to each type:

Hi Macks1974,
I read this also:
I've even tried giving up on wireless N and reverting back to G, but that's even slower.
Tried for a Wireless Mixed of 802.11n and 802.11g for 802.11 Mode.
Note: Wireless 300 Mbps Speed is only achieved by the following settings:
Channel Width: Auto 20/40 MHz
WPA Personal Security Mode then in WPA Mode using WPA2 Only
Cipher Type of AES
Group Key Update Interval: 3600 (seconds)
And also see this Sticky:

OK, I have everything set up properly as far as I can tell, and the Windows Network Adapter says I am getting 300 Mbps speed (although it does fluctuate from 243 to 300 Mbps). I'm still only able to transfer files across the network at about 5 to 6 MBps.
One thing I did notice is that that sticky says in step 1 that "...the router and adapter are both D-Link 802.11N products." Is that correct? It's not possible to get wireless N speeds by using another brand of wireless adapter? That doesn't seem right.
Also, even though I have a Broadcom wireless adapter and not a D-Link, would I gain anything by using the D-Link wireless utility instead of the built-in utility in Windows 7?

You and I both don't work for D-Link, but the statement is correct under Ideal Conditions with D-Link Products.
You can't use a D-LInk Wireless Utility with a Broadcom Wireless Adapter.
I have a D-Link DWA-552 Wireless Adapter Card for a Desktop Computer and I don't even use the D-Link Wireless Utility, I simply use Windows. Only the Card's Drivers are installed.

OK, I figured that was the case. I wasn't sure if there was some special feature that the D-Link utility has that the Windows utility doesn't.
I did turn off a couple of features in the DIR-655 setup, namely QoS and Extra Wireless Protection, and that has gotten my network transfer speeds up to about 9 MBps. But no matter what I do I can't get higher than this speed.
-
OK, interesting development.
I reset my DIR-655 to its factory defaults just to try something new, and after setting up the Internet and Network Settings I got around to setting up my Wireless Settings again. This time i started by leaving the 802.11 Mode as mixed b/g/n with Auto Channel Scan enabled, Transmission Rate set to Best, and Channel Width to Auto 20/40 MHz. I left the WPA Mode set to Auto(WPA or WPA2) and changed the Cipher Type to AES (since that sticky about 300 Mbps wireless N speeds says it is required); so basically the settings were almost exactly the same as before. Here is the speed test result:
(http://www.speedtest.net/result/808656670.png)
No luck, same poor speed results as before. After pulling out a little more hair I decided to try changing the Cipher Type. I changed it to TKIP (instead of AES or TKIP and AES) and restarted the router. After setting up the connection on my laptop I ran a speed test again. And...
(http://www.speedtest.net/result/808657801.png)
Bingo! I'm now able to watch high-quality streaming video on my laptop with no stuttering and excessive buffering like before. For whatever reason, apparently the AES cipher doesn't agree with my wireless adapter. The adapter properties in Windows list the speed at 54 Mbps now, instead of 300 Mbps like it did before, but my Internet speed is three times faster.
Unfortunately, my network transfers (copying a video from my wired desktop to my wireless laptop) are slower than before (Windows copy progress window averages around 2.3 to 2.5 MBps, while it was around 6 MBps before), even though the Windows wireless utility shows that my router is providing an 802.11n signal.
I'm wondering now if anyone has any ideas for how to increase my network transfer speed without sacrificing the great Internet speeds I am now getting over wireless, if that's possible. I guess I'm curious if this development with AES not working properly clears anything up.
EDIT: OK, after further investigation it appears that it might not be a cipher issue, it might be a problem with wireless N itself. It looks like I am getting the best internet speeds on my wireless laptop when connected via wireless G, not N. Now I'm not sure how to determine if the problem is with my laptop's wireless adapter or my router.
