Replacing a wireless module

There are a number of incompatible WLAN modules which are the same size and use the same miniPCIe connector. The compatible module is only available from OLPC.

Instructions:

• disassemble the top Disassembly_top
• unplug the two tiny coax connectors vertically away from the board
• undo the single screw holding down the module
• unplug the module from the motherboard
• reassemble in the reverse order
• the software may not recognise the module without going through the first boot sequence so either delete /etc/udev/rules.d/70-persistent* or reflash the operating system
