Losing network or internet connection after sleep/wake
I've created this as a new thread as it seems to be more prevalent with Mavericks and the very last update to ML but the problem has been around a while. It does seem to affect all types of Mac though from the other threads I have read and posted to.
The problem is essentially this: Intermittently, after a system sleep, the Mac appears to have no network connectivity (local and internet) and for a while the only reliable solution was to force the renewal of the DHCP lease or turning WiFi off and on again, after which the network would be restored.
There have been several theories postulated and a number of fixes, such as the DHCP renew, suggested but none of them have lasted for long but I now think I have this fixed as the following been 100% stable on my Mac Pro with wired ethernet connection for the last two weeks with no recurrences. I see no reason why this would not work on other Macs or connection types.
The problem seems to lie in the automatic location setting in the network settings, so here's what I did...
- Network settings - Location - Edit Locations
- Add a new location .. "Home" for example
- With home selected, click the cogwheel below the network services and choose "Set Service Order"
- Reorder the services so your preferred connection type is at the top
- After that, select each service in turn (assuming you have a few - like Bluetooth PAN etc)
- Make the services you are not using inactive
- Apply
Please post a reply if this works for you - it's been dragging on far too long and needs sorting out by Apple but if this is a good workaround for people then it will certainly do for now.
Mac Pro (Mid 2010), OS X Mavericks (10.9)
