I am looking for feedback to see if these problems with the DWA-140 are common and likely to be fixed by new drivers. If not, I need to return my adapter and I will need to decide that before newer drivers are likely to be available.

First, something positive.
D-Link is better than most in terms of access to tech support. They haven't helped me much, but they certainly made a good effort. Their resolve is enough to make me want to stay a D-Link customer even though I am still having a lot of problems.

Now for the complaining.
I have version B of the DWA-140, and I am trying to use it in Win7 Ultimate, 64-bit. My router is a DIR-615, which seems to be working fine on an XP machine. I downloaded and installed the latest drivers for the adapter (v1.60), which supposedly works with Win7, 64-bit. I was able to get connected once for just a minute or two, but after many hours uninstalling and re-installing I am getting nowhere. Here are some of the symptoms:
* I cannot connect -- other than that one experience. Even disabling alll security doesn't seem to help.
* Sometimes I can see my network, and sometimes I can't.
* When I have the adapter installed, it runs very slow. Boot up and shutdown take about 15 minutes compared to 2 minutes without the adapter.
* When I first boot up and the adapter is looking for the networks, any software related to the network including the D-Link connection software and the installation wizard freezes.

To me, these problems look like they would probably be solved by new drivers, but I'm not real sure. Please talk to me.
