I was the one who mentioned the ralink drivers. I heard about them in the reviews for the DWA-140 on newegg. That's what I used and I've had no problems at all. I run windows vista home basic 32 bit.

Ralink drivers can be found at the link below.
The drivers you're looking for are RT2870 (for the DWA-140)

Hope this answers your question.

My Girlfriend and I are using the same Wireless N 300 Mb/s USB nic, her computer is running Windows Vista x64 and my computer is running Windows 7 x64. The problem i'm having is that my computer connects at 270 Mb/s where her computer only connects at about 84 Mb/s it doesn't make any sense, both computer are around the same place in respect to the router. I have checked both of our network settings and they are as similar as they can get between Win7 and Win Vista. I can't quite figure this out. Any suggestions?

[FurryNutz]

Are the drivers for the USB nic up to date?
Is the router running single mode N at 5Ghz?
Possible that the bandwidth between the router and her USB Nic is messing up.

Check the properties on the USB Nic as well. Might have to tweek some of the settings there.

Hi TyanColte,

Make sure that she is running the Drivers for Vista 64. Make sure that her USB Wireless Ethernet Adapter is plugged directly into the Motherboard's USB port.

I'm using the USB extension Cable that came with it, should i not be using that?

Hi TyanColte,

Try the Ethernet Adapter by plugging directly into the Motherboard USB Port. Don't use any Extension Cables. Take them out of the equation.

Hi Another Joe,

If you are using a D-Link Router with a D-Link Adapter and only achieving 130 Mbps, your Router may be defective or the adapter may be defective, in that it can't stay in the broader 40 Channel Width.

Hence, you are seeing 130 Mbps.

I think I may have figured the cause of my problem. Dlink support staff couldn’t determine the issue so they ruled that the router was defective. I got a new router and still experiencing the same problem (router falls back to 130Mbps). I moved the router around my house to isolate possible sources of interference, no luck either. I tried multiple configurations of network adapters DWA-140,160 and internal cards all operating with the latest firmware versions. Here are my results:

• Base scenario: Hp laptop (Win xp) with DWA-160 HW A1 and Compaq laptop (Vista) with DWA-160 HW B1.
   - Initial connection speed of 300 Mbps but falls back to 130 after couple minutes.
• Scenario A: Hp laptop (Win xp) with DWA-160 HW A1
   - Connection stable at 300 Mbps (24 hrs +)
• Scenario B: Compaq laptop (Vista) with DWA-160 HW B1
   - Initial connection speed of 300 Mbps but falls back to 130 after couple minutes.
• Scenario C: Compaq laptop (Vista) with DWA-160 HW A1
   - Connection stable at 300 Mbps (24 hrs +)
• Scenario D: Hp laptop (Win xp) with DWA-160 HW A1 and Dell laptop (Win xp, internal intel adapter)
   - Hp laptop connected at 300, Dell laptop between 100-160. Stable connection
• Scenario E: Hp laptop (Win xp) with DWA-160 HW A1, Dell laptop (internal intel adapter), Compaq laptop (internal adapter)
   - Hp laptop connected at 300, Dell laptop between 100-160, Compaq laptop (g band) at 54. Stable connection
• Scenario F: Compaq laptop with DWA-140 HW B1 installed with Ralink driver
   - Initial connection speed of 300 Mbps but falls back to 130 after couple minutes.
• Scenario G: Hp laptop with DWA-160 HW B1
   - Initial connection speed of 300 Mbps but falls back to 130 after couple minutes.

It seems that the problem is D-link network adapters with hardware version B locking the DIR-655 frequency at 20 mhz for a fixed connection speed of 130 Mbps. For those of you using DWA-140 hardware B1 and/or DWA-160 hardware B1 with this router; are you experiencing a similar problem?

Next step is getting a cheap DWA-160 version A1 on ebay and selling the other adapters with hardware version B so I can get all my laptops running on As.

Hi Another Joe,

Have you disabled the onboard Wireless Adapters on the Laptops?

Hi Another Joe,

Yes.

[Another Joe]

I found the solution! I bought another DWA-160 HW A1. It was hard to find but it was worth it. Now I have my two laptops connected between 240-300 mbps all the time.

In summary, the problem was compatibility between the DIR-655 HW B1 and DWA-160 or DWA-140 HW B1.

This is obviously another case where the "B" hardware release is much worse in performance to the "A" version.  I have never had a problem with my 655A and I would never purchase a "B" version.

The 655A passes all attempted security tests and the 655B's have yet to pass them cleanly.  If that isn't reason enough for your attention, I don't know what is.

[FurryNutz]

I've never had a problem with my B router either. I'm using FW v2.00.

[marmoduke]

On the last thread, you stated that your B didn't cleanly pass the security tests.  I would call that a problem, but, that is just me.

[FurryNutz]

Port 0 is probably not a major problem its only one port and the port IS closed.

I recently bought a 655-B1 to replace an existing 615-C1.
The router connects to 2 laptops and a tablet (DWA-652, Dell 1505, and ??), as well as an iPod and smartphone. With the 615, I was getting 270-300 consistently with the 652, and about 250 with the Dell.  The only issue was that the laptops and the smartphone would drop connection every once in a while, and I'd have to reboot the router.

I bought the 655 on the assumption that a stronger signal would mean better connections, and hopefully that would address the connection issues.

I took screenshots between switching routers, and AFAIK the settings are all the same.
I can get a connection at 300 or so, but the speed always drops down to 130 after a little while.
I just spent most of this past weekend trying to find the magic combination of settings, to no avail.
I still have the same neighbors(!), the hardware hasn't changed; the only difference that I am aware of is that I've changed the model of the router.

It's looking like I will revert to the 615 and see if I can return the 655.
I'm just baffled as to why the 652 (Xtreme N) and the 615 (N 300) performed better than the 652 and the 655 (both Xtreme N).
