I have restarted the laptop, accessed as guest, and only resently did a hard reset.  This last seems to have mostly worked, but yesterday the same problem appeared while on campus.  I have a suspicion that the problem may be environment sensitive (it seems to work in my apartment, but (after walking in cold), it seems to fail when I get to campus).  However, the problem only started with the last update to this laptop.  The unclear correlation is that this last update it received was in late autumn.  When my laptop is warm, it seems inconsistent as well.  I am not sure whether this is a hardware or a software problem.  (If hardware, I would appreciate suggestions of alternative ways to access wifi, such as a comparable usb-wifi alternative that is compatabile with a chromebook)
