No issues connecting with CM6. Every now and then it would randomly disconnect and still show as connected but that's been on every post sapphire 1.0 rom that I've tried.
I'm on the same base as you are Cory. WiFi on my device is working flawlessly. I spent roughly an hour last night completely punishing it and all was well.
I did a total wipe, went back to stock and everything and started over. And the problem seems to be fixed. Im back on CM6 all is well, I did convince verizon to send out a replacement. So it all depends on what arrives at my door a D1 or a D2.
