Hi When I config my dlink router DIR-645 more then 20 times, sometimes if i have more lucky I see that my speedconnection between laptop and dir-645 is 150 Mbps. The 150 Mpbs is ok for me because when I using my usb stick wireless then I have 300 Mbps it the problem of my wireless adapter in my laptop. But most if it i have only 65 mpbs and with the usb wireless adapter is that 144 Mbps.
My question is why is it sometime ok with 150Mbps ? and most of the time only 65 Mbps.
The stranged thing is the follow I configur last month the router ok so speedconnection between laptop and router 150 Mbps. yesterday i take the plug of the main voltage out. I put it right back in and what I see now it's 65 Mbps ??
It's very strange with this anybody that can help me by this please?

To to get 300Mps on a connection you first need to make sure the wifi adapters are supporting of that connection speed. Then you need to do the following:
 
Set single mode N?
Set WPA-Personal. WPA2/AES only.
Ensure Auto Channel scan is enabled and bandwidth is set for Auto 20/40.

if your devices support 300Mb then you should see it.

Ok i have  a usb wifi adapter 300 Mbps but when I reset the router and do the follow as above still 144 Mbps.
But what I like to know for example, when my internet connection is 50 Mbps and my connection speed between router and laptop is 30 Mbps and i do a speedtest is then the max download speed 30 Mbps or more behind the 50 Mbps when my laptop is very close to my wireless router??
Have also here a dir-655 no problem 300 Mbps so I like my 655 and not my 645

What Firmware version is currently loaded? Found on routers web page under status.

Have you set up the 645 in the same way as the 655?
What FW is currently loaded on the 655?

What Firmware version is currently loaded on the 645? Found on routers web page under status.

Firmware: v1.01

[FurryNutz]

I see there is a beta 1.02, not sure if this would help any.
Ensure the USB WiFi adapter drivers are up to date as well?

Could U give me the url for download the beta fw version ?

Also make sure that the adapter is configured correctly to use the N mode. I have seen some settings that have the options however they are not enabled.

New Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy

All 802.11n certified routers must now implement a good neighbour policy. The router can support 20 and 20/40 channel width, however, will fall back to 20mhz only if the router detect another device nearby running on the same band. In other words, if your neighbours are running a 2.4ghz network. your router will fall back to 20mhz which negotiates to usually between 130-150Mbps. Older revisions of 802.11n routers did not implement this and thus will show up to 300Mbps. Without getting too technical, if this wasn't implemented, everyone would be cutting everyone elses signal and causing severe wireless disconnections.

If you want more information a google search for "20/40 coexistance" should give you more technical information.

As much as this may seem like bad news, the good news is the 5ghz band does not suffer from this issue and it is very easy to achieve 300-450Mbps without any issues. The 2.4Ghz band at 130-150Mbps should be more than sufficient to push through speeds that your ISP is dishing out.

As for the 65Mbps issue, all I could suggest is update the wireless NIC drivers, ensure you are using WPA2/AES and try changing wireless channels. That should do the trick, otherwise you may need to relocate the router or possible swap out your wireless NIC if all else fails to isolate the issue.
