I have been a linux user for the past one year.And I have noticed that all the distributions I have used so far have this trend of managing to block wifi access to windows computers on specific routers,though devices that have some sort of apple os continue to work fine.. By block , I mean these window computers aren't able to connect to the wifi(talk to it/make calls)

I was wondering if someone could tell me why such a trend is being observed or if it is just a coincidence.

I now am running ubuntu , earlier on it was sabayon,and then gentoo and before that it was arch ..the problem seems to be independent of what distribution I use.

Usually the I have never had a problem, so I never bothered checking on any windows computer , the problem has affected windows users in the past who have mostly been room mates /house mates ...but I have always wondered.

I've mixed windows and Linux wifi clients for years with no sign of what you describe. is this always the same windows machine you are talking about? – Frank Thomas Oct 6 '13 at 6:23
You really don't describe the problem. What happens to the Windows computers that you describe as "blocked"? Do they still connect to the WiFi network? Can they still communicate with the router? Do they get assigned IP addresses? – David Schwartz Oct 6 '13 at 6:28
What hardware are you on? What distributions? – DanteTheEgregore Oct 6 '13 at 6:33
Can you please post the Vendor+Device code of your wifi card? Ty – MariusMatutiae Oct 6 '13 at 7:47
And, btw, yes, I have seen similar behaviour, but never with an Intel card. Broadcom wireless cards under Linux occasionally produce this kind of behaviour, when they use proprietary drivers; a switch to the open source driver b43 solves the problem. As for changing OS, this will not solve the problem because all wireless drivers are the same inside Linux, and many are actually in-kernel. Are you using iwlwifi as a driver? – MariusMatutiae Oct 6 '13 at 8:29
