And not unusual at all. But before I go there the more common thing I have to do is to get Apples to forget all prior hotspots then I have a fresh start.
http://www.howtogeek.com/195912/how-when-and-why-to-repair-disk-permissions-on-your-mac/ covers the permissions angle of how, why and when.
and I have to restart the computer to get connected again.
This started about several months ago.
Right now I am traveling, so I have to use all public WiFi; Starbucks, B&N, the public library’s, or my hotel’s WiFi.
It very rarely if ever stays connected when I wake it from sleeping overnight, and then it is for another fifteen or so minutes, and I always have to restart it again.
When it cuts out, the reception bars don’t disappear or move, so it looks like I am connected.
Sometimes, I turn it off before it cuts out, and later it is able to reconnect (for twenty minutes) without having to restart it.
Three possible reasons immediately come to mind;
(1) Several months ago, I had my permissions(?) changed at the Mac store G. Bar (I was getting asked to enter my password when deleting or renaming some M4V files, and/or moving them to a different folder on the same Mac, or to a ext. HD), and I still have that problem!
(2) I tried disabling Adobe’s Acrobat and Flash Player programs, and did it improperly
(3) Less likely, I was hacked!
I first noticed “a” (not “the&rdquo
Airport/WiFi issue several months ago, not too long after #1 was performed. Sometimes, when attempting to turn off Airport, it would not immediately turn off, I would see the reception bars move like it was trying to find reception when turning it on, and still does that occasionally, then eventually turns off.
I tried network>assist me>diagnostics which a few times (usually not though) said I have a connection, yet I can’t connect to a page as it doesn’t show any options to connect to.
Most other times though, I do the same assist me and it says status off, and I click the turn airport on button and it doesn’t show any signs of movement or showing I’m connected.
I tried the advanced page, picked the correct network >OK and still nothing.
When I don’t see any reception bars, it doesn’t show any other networks to join in the drop down list at the top of the screen and says that Airport is off.
Then, when I restart, Airport and the reception bars appear by themselves, and I am connected.
Sometimes I get the “no airport card installed” or “airport not configured” message @ the top pane when clicking the Airport icon.
Other scenarios are, I don’t see any Airport icon at all in the left pane of the network dialog box, only Ethernet and FireWire icons.
I trashed Firefox and re-installed it, and my Google is up to date.
Is there a WiFi folder and can I replace it with a new one? I just don’t want to restart the computer eight or nine times a day.
Does my Airport card need replacing?
Will this problem will definitely subside if I upgrade operation systems?
I’m sure I would have internet via Ethernet, however, no public places offer that option for the public.
Thanks in advance for any suggestions, though it may be a while before I can reply!
