Multiple devices not automatically joining previously known network
Multiple devices (two phones, two laptops) are now frequently failing to auto-join long-known home wifi network. Been the same network, same password, etc. for years, never an issue until recently. Now, 50% of the time, the devices won't automatically join, requiring manual join/password entry to access. All settings on all devices are unchanged, no updates to (i)OS's, no changes in Airport router or cable modem.
Router issue perhaps?
