I found some bizzare issues where WEP and WPA access points coexist,
and the client is configured with passwords for *both*.

The usual response to this is "why use WEP when it is insecure etc etc
etc" but that sidesteps the issue, and WEP is sometimes required to
support some older device. Also some modern devices can do WEP only,
not WPA; e.g. the well known Joikuspot software for Nokia phones which
turns them into GPRS/3G-WIFI radios.

That issue was found on both the Iphone4 and the Ipad2, IOS4.x and the
latest 5.x. And both the Iphone and the Ipad had been replaced (both
failed in unrelated areas so the Apple shop exchanged them under
warranty).

Incidentally, it's obvious from the Apple forum that the general wifi
issue is on the Ipad2, not the older Ipad.

Even after the firmware upgrade to the Draytek 800 access point, the
connection sometimes falls over and does not reconnect unless one goes
into Settings and does a fresh search for networks. I have never seen
this behaviour with any wifi device I have ever had. I've had loads of
wifi issues related to passwords not working e.g. the different ways
that a passphrase is hashed into a WEP key, but the Ipad2 problem is
different.

Draytek may not be well known in the USA but Netgear certainly are and
they have loads of issues with Ipad2s.
