    I recently purchased an Acer Aspire 5560-8431 (AMD A8, AMD Radeon graphics, 8GB, 750GB HDD, etc.) and tried to upgrade the WLAN card with a dual-band 802.11 abgn card (SparkLan WPEA-111n, Atheros AR9280 chipset). When I replaced the card Windows (Win7 SP1) seems to recognize the card and installs the drivers. However, the card doesn't appear to be "on" to any receive signals and, yes, I have checked the device settings through the Computer Management console.

    I have recently upgraded the BIOS to v1.17 but resulting in no change in the behaviour of the card. I chose SparkLan because the Atheros chipset seems almost universal in terms of compatibility and have had success using it in other Acer laptops. I have, also, tried to place the original WLAN card back in and now the original card doesn't work! I have placed the SparkLan card in another computer and it worked perfectly so it's not defective.

    I don't get it.

    Does anyone have any ideas or suggestions?

    Sounds like you may have damaged something on the laptop's main board which is related to the card, since the original one doesn't work now either.
