Excellent. Thanks for that.
If TKIP really broken or is this yet another weak-password story.
I can't answer all your questions, and it seems no one else has either.
However you already know that APs cooperate when on the same channel, so the best thing you can do is get your neighbours to change to non-overlapping channels. I have done this by visiting my neighbours, explaining the problem and helping them to change channel. Result: reliable connection. You might prefer to get the concierge to advertise good wifi practice.
If you end up configuring all your neighbours then you get a chance to distribute signals intelligently: ie, reserve two channels for big downloaders, and the other reserved to ordinary users (even a single channel is more than enough for 20 people browsing the web).
Non-standard wifi and N: generally speaking it is best for these devices to be configured for g or b and disable the fancy feature which stomps on signals and acts like interference. They will do better not just you. Disable anything out of the ordinary.
As President Rossevelt's doctor is quoted as saying, words to the effect of "A physician could expect to see one or two cases in a whole career."
Genetics is just another red-herring.
People using well-documented, flexible frameworks are suckers.
The carriers have to make money: texts are used to subsidise other services. If they aren't allowed to charge such a high fee then voice goes up. There are plenty in the UK who barely use voice, so the carriers must find ways of making money from them.
Unless one accepts a general principle against subsidy (which infact I personally do as it obscures, causes distortions and also bubbles) then this isn't an issue. For government to interfere, which is effectively what this article logically ends at, would be absurd since governments are subsidy addicts.
In anycase "it's just a philosophy" is an illogical response. Marxism could be called 'just a philosophy', but equally with Stallman's position it causes human misery and removes human satisfactions by contradicting your nature.
I merely point this matters out for your information, since I am not affected by them in anyway, so that you may live long and prosper.
