In June I started to notice problems with the connection speed between my MBP and Time Capsule.
In the beginning I thought the problem was to do with my Time Capsule, so after a bit of trouble shooting involving formatting and changing of settings without any change I did a bit of a comparison on speeds with @PatMahon.

Still no joy so it was time to give Apple a call and get some use from my Applecare policy.
After going over a few details of my issue with them we decided it was not a Time capsule issue as first thought but it was in fact a problem with my MBP, specifically the Airport card.

Getting to this conclusion was now quick or easy by any means, apart from the obvious ping tests and testing on a clean user account etc I did a archive and install of the OS, then a complete clean install…

Still no improvement.

So off my MBP went to Apple to be fixed, all boxed up and off it went.
A few days later I received a phone call from Group 8 (the company carrying out the repairs) they asked me a few questions and decided to replace the Airport card.

I happened to be on holiday so I had a bit of a wait until I got the MBP back.

Unfortunately once I had reinstalled my account from my backup I noticed that it was not in fact fixed, it was to tell the truth now worse than before.

Back on the phone to Applecare and I explained the situation was now worse than before, I had one more test to do…

Boot from the instal DVD and ping test, this confirmed once more that it was not a software issue.
I was sent a program by Apple that gathered some info and this was sent to Apple for the engineers to take a look at.

So here I am waiting for a reply from them to find out what is to happen next, I imagine that my MBP will be returned and ill be back to using my iPhone for a while.
