Retired IT professional, with iMac, MacBook, MacAir, Touch, iPad2.
I had some connection problems with the iPad 2 and used this site to explore solutions. I have a Netgear router supplied by a Mac specific ISP. Apart from the iPad2 I had not other connection issues.
I use an Airport Express when I travel so tried that as an extension to my network. The iPad2 connected first time and I have had no issues since.
