Wifi issues long term fix - Mountain Lion dropping connection

Further investigation on the Apple site - I found that 10.8.4 has a wifi diagnostics facility. Access this by pressing the option button and clicking the wifi connection. This just let me know there was an issue. I rang Apple and the first thing we tried was rebooting and holding down cmd-r until the apple logo and spinning icon appeared. This went into diagnostic mode.

From there we tried browsing the internet, and again the connection dropped.

Very strange that it was only the two Apple MacBooks (Air and Pro) that were dropping. iPhones, iPads and windows PC were fine.

So we tried turning of the router (Time capsule) for 30+ seconds and turning it on again. When it rebooted the two Macs now reconnected and maintained consistent wifi connection - perfect! The helpful Apple support analyst explained that sometimes with too many wifi devices it can switch channels to compensate, and then get stuck on a channel. Hmm, not sure I fully understand that how that causes this. But anyway restarting the time capsule router has resolved the problem, thankfully.

I'm also doing an update of the other computer to 10.8.4 which includes an update of the time capsule firmware, which should ensure the problem has gone for good.

MacBook Air setup

After giving some consideration I decided to get the MacBook Air 11 inch 64 GB laptop. The plan has been to use it as a cloud based device.

In order to utilise it as a cloud based laptop I have done the following;

• Followed the welcome screens and setup a user account
• Added in my iTunes Apple ID to get iCloud. I have two apple IDs one for iTunes and the one I had for mobile me. So I had to undo the iCloud service and put in my mobile me Apple Id - this didn't allow for notes and email - and it was asking me to create an iCloud email address - that is when I realised it was the wrong id. I then changed the ID and was then able to get all the iCloud services working.
• Configured my iTunes Apple ID in iTunes, authorised the new computer and setup iTunes match on my other MacBook Pro. Now when I got to iTunes on my Air it allows me to either download my music or stream it - really good. Strangely nothing appears on the iTunes match tab - which was slightly confusing initially.
• Installed software and software updates from the App Store, so this got me Pages, Numbers, Things, Xcode.
• Installed Evernote, Spotify, Drop Box
• I then moved my documents/projects folder to Drop Box on my MBP and moved my code to the DropBox
• On the Air I then selectively chose the project and code folders I wanted, and selectively chose some of my photos to download
• Setup photo stream in iPhoto, I'm not sure if I can get the DropBox photos to render within iPhoto so I am viewing them outside iPhoto.
• Configured iPhoto and Facetime - and my Air got added, and all the other devices notified me of this.
• Added my backdrops folder to drop box and setup a decent background to my desktop
• Bought a cover off of Gelaskins
• Now the policy is to do everything on this device in the cloud, and all setup.
