I'm in the process of deciding which wifi will replace the default. However I can find two sizes on ebay: one has the parts only on one side of the PCB (like the original one) and some (like some newer Atheros) have electrical parts on both side of the PCB (e.g.
Atheros AR9281 AR5B91 Wireless NWiFi Mini Card 300M B12 bei eBay.de: PCMCIA Cards Controller (endet 05.08.10 08:50:33 MESZ)). Has anyone used a double-sided wifi and can tell if it still fits?
