Any details about the captive/public wifi login screen browser

alright I may have some light to shed on this:

I just got off the phone with an Apple Engineer and he said a few things to me that make sense. He has stated that the "crippled browser" should never be displaying any other page than our captive portal page. He stated that if after logging into captive portal I am redirected to www.apple.com/library/test/success.html the iPad's "crippled browser" will close. If I see another page (like I saw apple.com and not http://www.apple.com/library/test/success.html which would have closed the browser.) it is likely that the system hosting captive portal is not directing me to the exact original page requested. Which was http://www.apple.com/library/test/success.html It could in fact be truncating or altering the original URL, which is possibly why I see apple.com's main page in the "crippled browser"

No resolution yet, as I still need to confrim that the wireless controller is indeed doing this, but it makes sense, and might help.

If this is in your home, do you have an older microwave oven nearby? Or a 2.4GHz cordless phone? Baby monitor? Anything else "wireless" (that's not a wireless router/access point)?

Have you tried changing the channel of the wireless on the router? Many newer routers will do a "site survey" and indicate an unused wireless channel.

I have had similar problems with wireless in the past and solved it by changing the wireless channel.
