This is problem with brcmsmac driver. This driver work perfectly but only with limited wi-fi channels like I said in first post. On high number wi-fi channels this have problem with connection to my router. On bcmwl-kernel-source I don't have this issue. So maybe Linux kernel team should fix issue with brcmsmac driver ? I prefer open source drivers instead restricted so this is very important to fix it. If they fix it a lot of people can simply install system without additional drivers and this will be so great!
