drStrangeP0rk - will you please stop insisting that there is no WiFi issue. Just because you haven't seen it yourself doesn't mean that it does not exist. I have been working for software product companies for over 30 years and I am fully used to people getting things wrong or misunderstanding things, but in this case I can assure you that something is wrong with IOS6.
This is all about support for legacy infrastructures. When we release a new or upgraded product, we have to verify that it works with existing environments or, it there are changes that require users to change their environments, these are advised in release notes. It simply isn't an acceptable option for Apple to advise people to reset, upgrade or downgrade half the routers on the planet, just because Apple choose to use a new feature that many access points cannot support properly.
What you see on the forums is simply the tip of the iceberg - most users will just assume that there's a problem somewhere else, or not even notice until they get hit with a 3G data bill. (I know this, because I have asked less tecchy friends and relatives who upgraded and this was their response - they aren't logging calls, but do see the problem).
The bottom line is, before IOS6 we could connect pretty reliably to the majority of WiFi access points at home, at work, in hotels, cafes and other public places. Since the upgrade, a significant proportion do not work.
There IS a problem with WiFi in IOS6.
Oh, and if you actually read the article on CNET, the author himself, Brooke Crothers, is experiencing the problem (read the "...count me in as an affected user..." paragraph), so how can you claim CNET haven't seen the problem?
