Wrong thread for those questions. Here's a quick reply - but discussion should be in other threads...
Are you sure you enabled the wireless?
Settings -> Wireless & networks -> Wi-Fi checked [x] ON then Wi-Fi settings under that and search for your network. Does your router block unknown MACs? Mine does so I had to add the MAC to allowed connections - a router setting.
After rooting and installing Google Market I installed Nook with 2.1
Please do NOT hijack threads! It's rude and will hinder you in getting help.You were already told this was the wrong thread to ask questions in and ignored it. Please start your own thread and ask there. I will tell you that it is not possible to upgrade to Android 2.2 at this time.
Again, start your own thread-and read the stickies as well. The instructions to add the Android Market are there.
Finally got myself the "Shoot Me" app to capture my Home Screen. It took me forever to muster up the courage to attempt the Root and Clockwork Recovery mod but I'm SOOOO happy that I did it. It makes all the difference in the world. I really can't imagine spending $700.00 on a tablet with all that this community has accomplished with the Coby.
