Comments on: How to set up Gentoo wireless networking on AMD64 http://www.xaprb.com/blog/2006/02/11/gentoo-wireless-networking-on-amd64/ Stay curious!

This function calls ath_hal_getrfgain() and if it returns HAL_RFGAIN_NEED_CHANGE, the function ath_reset() is called. AL_RFGAIN_NEED_CHANGE may mean that new gain values must be loaded, but ath_reset() does many other things including dropping any enqueued frames. As we don't have a datasheet for PHY chip of Atheros PHY (5112), we are not sure but it seems it refers to ath_hal_getrfgain() (as defined in openHAL sources). Could you explain ath_hal_getrfgain() functionality of current HAL(not openHAL), and why does it need a full device reset? if some one gets the answer mail me at nikvoodoo@gmail.com can any one slove this

I also have a WLAN card with an Atheros chipset and it works fine since the day I bought it. No problems at all.

The MadWifi project does great work, and with emerge there shouldn’t be a problem to install the kernel module.

But if you upgrade your kernel, don’t forget to rebuild the atheros module. The last time I did an upgrade I wondered why there was no internet connection afterwards ;-)

Nice weblog, good opinions, I like it.
