Saptamana trecuta v-am spus ca fara sa admita oficial existenta unei probleme, Apple isi instruieste angajatii sa schimbe orice tablete iPad 3 care sunt aduse de clienti ce reclama probleme ale conexiunilor Wi-Fi. Informatiile vin dintr-un document Apple Care care a fost publicat atunci si se pare ca intreaga problema ar putea avea legaura cu modul in care iOS-ul administreaza energia transmisa catre componenta Wi-Fi din chip-ul Broadcom BCM4330. Un expert in astfel de probleme sustine ca totul ar putea fi legat de noile functii pentru power saving incluse in chip-ul celor de la Broadcom si ca rezolvarea problemei prin simpla resetare a configuratiei Wi-Fi denota faptul ca un update al iOS poate rezolva usor problema.
It’s unlikely that hardware is the primary cause of the [problem]. This is probably a software problem, or a hardware quirk that software must negotiate. If this was hardware related, it would almost certainly have to be an error in assembly or failure in the chip itself. However, chip-related failure would likely be more absolute in its effects. The fact that a network settings reset can sometimes resolve the issue points strongly to a power-saving feature run amok. [The Broadcom BCM4330 chip] boasts a new design including several new power-saving features. Wi-Fi can be a hungry customer in mobile devices and Apple knew that the new LCD and its requisite monster truck GPU would be guzzling battery juice. They had to go aggressive on performance per milliwatt on every other component.
Exista posibilitatea ca Apple sa fi intentionat sa imbunatateasca autonomia tabletei in timpul utilizarii unei retele Wi-Fi si setarile facute de ingineri sa nu functioneze chiar atat de corect cu toate modelele de routere. Oricare ar fi adevarata sursa a problemei, partea buna este ca un update al iOS poate rezolva totul si probabil iOS 5.1.1/5.2 va scuti utilizatorii de batai de cap. Chiar daca problemele cu retele Wi-Fi ar fi usor de rezolvat, ramane de vazut cum va rezolva Apple problemele cu conectivitatea 3G.
