Bug: WiFi fails to auto-reconnect after long idling
I really thought this bug would become history with the new MacBook Pros. Not so fast. Not the latest software, not even the latest and greatest hardware was able to permanently fix this damn bug. I can't believe after all these years, it's still an issue. I went though so many Macs, so many OS's, and it's there every damn time.
[crying]
I feel your pain
I work in a small business
They use an Pancake style AirPort Extreme
The Ssid for the 2.4 and 5 ghz radios are different
The Ssid is hidden
They use MAC authentication
Just about everything that Apple says don't do.
Doing a network scan (inet) there are 40 + DHCP address active in the scan.
There is a bunch of legacy 802.11 b/g junk on the network from webcams by the doors,
Old hp printers, scanners, fax machines.
For pcs there are Windows desktops and laptops running Windows 7 and 10 and a few MacBooks and an apple air.
I use my own 2012 MacBook Pro retina. An iPhone 7 and and Apple Watch from my cubicle.
I'm not the system admin and I don't get to tell them how to run their business, just a consultant.
The single biggest help for me and connection issues was
After making a connection Forgetting The Network
Shutting down the machine, complete power off
Then when reestablishing a Network 2.4 GHz connection
PICKING WPA2 Personal in the Security dialog
Box before putting in the network password.
I use 2.4 GHz because my Apple Watch does not have a 5GHz radio and everything plays nicely.
As A test After giving the IT guy the MAC address I just added an iPad with no issues.
