Like droves of others, I've had serious issues with with my iPad maintaining a wifi signal about 40-50 feet away from my wireless router. Even when it did manage to connect, the connection was extremely slow even though my iPhone 4 had a very fast wi-fi connection. I tried all the troubleshooting procedures on Apple's Support page and even tried a restore at the request of their Customer Service rep. When that did not work, they asked that I send it in for them to replace it. I should have it by Friday but I'm curious if replacement units have fixed this problem for any of you or if it's simply a persistent design flaw inherent in the current generation of the iPad. Has anyone had their iPad replaced due to the wi-fi problem? If so, did this resolve your problem??
