Wi-Fi woes striking early iPad adopters are currently being reported at Apple's Using iPad Discussion Forum. Users are discussing problems ranging from weak Wi-Fi reception to Wi-Fi connectivity problems. 

The worst problem being reported is the weak Wi-Fi, and that discussion has been viewed nearly 9,800 times amongst 113 posts. This problem isn't new to us since we have also experienced problems with Wi-Fi reception on our new 64GB iPad. In one case, we had an iPhone with full Wi-Fi signal strength right next to it and the iPad flipped back and forth between one and two bars. The iPhone remained steady the entire time.

The other problem, which doesn't seem to be as bad as the first one, is a complaint about the Wi-Fi not connecting, and that discussion has been viewed over 1,249 times amongst 29 posts. We have not yet experienced this problem with our iPad -- so far.

Apple has posted one technical bulletin about iPad Wi-Fi in iPad: Does not automatically rejoin known Wi-Fi networks, which mentions dual banded networks (i.e. Airport Extreme) and some issues in that environment that may cause problems for the iPad. We suggest you take a look at this bulletin if you are experiencing Wi-Fi problems and are running this kind of network.

Ironically, this isn't the first complaint we've heard about Wi-Fi on an Apple handheld device. The original iPhone, the iPhone 3G, the iPhone 3GS and the iPod Touch all experienced similar problems initially. Hopefully, the problem can be resolved with a firmware update.
