The wireless on my iPad has virtually given up, it works a metre or less from the router but any further away it fails. I have heard of Tan Telecom in MBK as being a reliable service centre, anyone else got other recommendations. Apple were useless and just wanted to charge $$$$$$$$ for sending it to Singapore.

Moved to the Apple forum.

Did you do some troubleshooting at all?

Simplest one being turning the iPad off and back on.

Network reset?

Also, where are you located? Is MBK only in Bangkok or in other cities around thailand as well?

Try a clean install of the OS. It might not be a hardware problem.
