Reset Network Preferences (OSX)

At times there may be one or two occasions where the network adapters such as AirPort or the Ethernet in your Mac suddenly cease to function properly, be that from hardware fault, software fault or accidental modification faults to your network. There is a way to reset them when things stop working as they should. If none of these methods work, you may have to send your machine in for some repairs if it’s hardware fault.

Resetting PRAM –

First steps, always try resetting SMC’s PRAM to see if that fixes the problem. Shutdown your computer and remove the power cable for atleast 15 minutes or so, I usually tend to do it in 7 to 8 minutes. If you’re doing it on Macbook or Macbook Pro, remove power cable and battery pack. Then you’ll  plug them back in. Next hold down  ⌘ + ⌥ + P + R   as you turn it back on, You should know if it was successful as usually you’ll hear the startup sound twice.

Network Preference File –

If the above method didn’t work then try this, this may well guarantee a 100% proper fix. In guidance for this I’m using Mac OSX 10.6.8 Snow Leopard, newer systems like 10.7 Lion will most likely be the same. Older systems may well differ from what I’ll show you here.

Navigate to /Library/Preferences/SystemConfiguration in Finder  (⌘ + ⇧ + G).  You will find two files there which relates to your network. NetworkInterface.plist and Preferences.plist, you will want to rename them and give them the extension on the end with .bak, so it looks something like this;

You will have to change the current permissions temporarily for that folder so you can rename them just hit  ⌘ + I  to bring up information, then click on the Padlock and enter your password if it asks for one, next click on the + sign and add yourself into the group permissions and change it from Read Only to Read & Write then make your changes to those files. You can go ahead and leave the permissions for that folder or revert them back to their original state to Read Only for you then remove yourself by clicking on your name then click on the – sign. Next all you just have to do is Reboot and should be in working order hopefully, this method should reset and restore AirPort and Ethernet together.

When you’ve done your Reboot, the computer will automatically recreate those Plist files you edited and be in ready normal working conditions. I think it will be safe to delete the old Plist files after the computer has created the new ones, as you shouldn’t need it anymore.

PSN Trophy Sync

Quite up until recently I was unaware of a certain what looks like, a bug or glitch with PSN Trophy’s on PS3. I didn’t notice it before until I went to go play Dead Island and Sonic Generations that I noticed I was receiving the same Trophies I’ve already obtained in the game from regular play. So I hit up a search on Google to see what could be done about it. It turns out that it’s something to do with the Trophy

PSN Trophies

Sync between your PS3 and the PSN Server with your account on it. What I have seemed to of discovered is that if you’ve obtained alot of Trophies for a certain game while connected to PSN, then go back and play them while signed out for a while, and you obtain more trophies for a certain game, then reconnect back online, I would probably say that the time frame would be 3-5 weeks maybe more of offline mode while playing games that have Trophies, that was roughly how long I was at the time due to Internet connection issues and constantly being signed out all the time, then asking me to update the system firmware, blah blah blah… then where I just decided to leave it signed out.

 

I’m guessing the whole thing about this weird glitch is probably a fail-safe to prevent people from cheating, trying to obtain a certain trophy without actually achieving it properly, or something like that, but what I did dig up that it is some sort of glitch that can happen sometimes, the simple fix to it is to just “Sync with Trophy Server“. So from the PS3 XMB screen go to Trophy which is under Game, then press △ to open the Side Menu then Press X to sync with the server, this may take some time to sync, but once this is done, go back into the game(s) that had missing Trophies and it should all be there again.
