[ath9k-devel] External LNA gain.

[Alex Hacker]

Hellow all,
Does anybody knows how the xlnaGainCh field in EEPROM modal header should be
used to achieve a correct AGC behaviour? This values is always programmed in
a card's EEPROM but not used in ath9k driver, except in the debug code. How
the AGC can get into account the external LNA gain? Is the some default values
programmed by initvals?

Best regards,
Alex.

Which board?

Hello Adrian,
If you asking about chipset. I found that chips >= AR9220 do not use external
LNA bypass, switching the on-chip LNA instead. But I see that ath9k never use
xlnaGainCh. How the AR5416 works in this case?

Best regards,
Alex.

Hi Adrian,

Hope u get the infos for the LNA-gain bug out of the company.
We noticed in Vienna, that near all UBNT Products should have the problem.
A comparison between Bullet M, NanoStation, NanoBridge ans AirGrids shows,
that only Bullet M has the expected sensitivity. Guess it has 2do with the
LNAs.

Good luck
Joe
