Got my iPad on Tuursday (UK) and think it's amazing. 3G model so no problems with the wi-fi signal. My issue though is if I turn the wifi off and turn back on or shut the iPad down and restart it does not automatically join my known home network. I have to go into the setting menu and select my network, no password prompts, then joins straight away. My iPhone shows no such issues and as long as the wi-fi signal is there it connects without any interaction. Anyone else noticed this or know what I'm doing wrong?
