Hello,

WiFi on my Acer Aspire 5739G is currently broken on linux-next. I bisected it to the following commit:

commit 97f95c93c8ed5177371e75275f236513152fa308

iwlwifi: remove support for fw older than -16.ucode

This issue was already reported here [1]. I'm just adding some more hardware details (and am not subscribed to linux-wireless so I can't reply over there).

It's failing with:

    iwlwifi 0000:05:00.0: enabling device (0000 -> 0002)
    iwlwifi 0000:05:00.0: can't disable ASPM; OS doesn't have ASPM control
    iwlwifi 0000:05:00.0: Driver unable to support your firmware API. Driver supports v5, firmware is v139658497.
    iwlwifi 0000:05:00.0: Direct firmware load for iwlwifi-5000-4.ucode failed with error -2

    iwlwifi 0000:05:00.0: request for firmware file 'iwlwifi-5000-3.ucode' failed.

    iwlwifi 0000:05:00.0: Driver unable to support your firmware API. Driver supports v5, firmware is v84148496.
    iwlwifi 0000:05:00.0: no suitable firmware found!

Here's some more info on my wireless chipset:

05:00.0 Network controller: Intel Corporation WiFi Link 5100
Subsystem: Intel Corporation WiFi Link 5100 AGN
Flags: bus master, fast devsel, latency 0, IRQ 31 Memory at c0400000 (64-bit, non-prefetchable) [size=8K]
Capabilities: [c8] Power Management version 3
Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
Capabilities: [e0] Express Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting
Capabilities: [140] Device Serial Number 00-1e-65-ff-ff-80-25-f6 Kernel driver in use: iwlwifi
Kernel modules: iwlwifi

The laptop isn't _that_ old so I'm surprised the driver is ripping out support for it... Is there some other driver I should be using?
